Abstract

PROBLEM TO BE SOLVED: To facilitate sound generation that matches an intention of a player's performance operation while preventing an adverse effect on auditory feeling even when a continuous performance operation is performed with an overlapped part.SOLUTION: An electronic musical instrument includes one or more assigners that select pitch which generates sound on the basis of a predetermined rule in accordance with an operation state of a plurality of operation sections each corresponding to the pitch, stores a selection history of the pitch of each assigner, and changes the predetermined rule for the assigner whose stored selection history has satisfied a predetermined condition to a later-arrival priority that selects the pitch of the operation section in which a sound generation start operation is performed last (S22, S23).

Description

  The present invention relates to an electronic musical instrument that selects a pitch to be generated according to an operation state of a plurality of operation units, a program for causing a computer to realize such a pitch selection function, and an operation state of a plurality of operation units. The present invention relates to a pronunciation pitch selection method for selecting a pitch to be generated in response.

  Conventionally, in an electronic musical instrument, there are provided a plurality of assigners for selecting pitches to be pronounced from predetermined pitches according to a predetermined rule, and a pitch selected by each assigner is assigned to a tone color corresponding to the assigner. It is known to make it sound.

Then, by using this plurality of assigners, for example, if a rule is set so that one assigner selects the lower pitch and the other assigners select the higher pitch, the bass is automatically set. The high-side and high-side sounds (for example, accompaniment and melody) can be played with different tones. Also, depending on the rule settings, the same pitch can be selected for multiple assigners to produce a sound like unison performance of multiple parts, or different pitches can be selected for multiple assigners, such as ensemble performance of multiple parts. You can also pronounce.
Such an electronic musical instrument is described in Patent Document 1, for example.

  Patent Document 2 discloses an electronic musical instrument that assigns a predetermined number of parts to a pressed note according to a rule corresponding to the number of key presses, and causes each note to sound with the tone of the part assigned to that note. An instrument is disclosed. According to this electronic musical instrument, a predetermined number of parts can always be sounded regardless of the number of key presses.

Japanese Patent No. 2565069 JP 2010-79179 A

By the way, in the case where the pitches to be sounded are selected using the above-described plurality of assigners, the method described in Patent Document 1 does not always produce a desirable sound.
For example, when playing the previous sound and the next sound consecutively, such as when playing legato, it is inconvenient for sound generation when pressing the key of the next sound before releasing the key of the previous sound was there.

  FIG. 19 shows this example. In FIG. 19, the vertical axis represents time, the horizontal axis represents pitch, and the band at each pitch indicates the period during which the key of that pitch is depressed. In the example of FIG. 19, the key with pitch n4 is pressed, and before the key is released, the key with pitch n3 is pressed. Then, since the key of pitch n4 is released immediately thereafter, it can be assumed that this performance is a performance intended to continuously generate the sound of pitch n4 and the sound of pitch n3.

  However, in the method described in Patent Document 1, each assigner selects a pitch to be sounded in response to a key pressing operation, while a sound corresponding to a key that has been released is being sounded during a key releasing operation. It just sends a key-off signal to the sound channel. That is, during the key release operation, the pitch is not selected by the assigner.

  Therefore, for example, at the timing of KON1,2,4 when the key of pitch n4 is first pressed (simultaneously with the keys of n1 and n2), each assigner is pressed by three keys of pitch n1, n2, n4. In this state, the pitch to be pronounced is selected. However, at the timing of KON3 when the key of the pitch n3 is pressed, each assigner selects the pitch while the four keys n1 to n4 are pressed. Further, at the timing of KOFF4 when the key of pitch n4 is released immediately thereafter, the sound that is pronounced with respect to pitch n4 is simply muted.

  For this reason, in the period from KON1, 2, 4 to KON3, and the period after KOFF4, the relationship between the pitch order of the keys being pressed and the pitch selected by each assigner may deviate. is there. That is, from the performance operation, it can be inferred that the sound of the pitch n4 and the sound of the pitch n3 are continuously generated, but the sounds of these pitches are pronounced in different timbres, and thus unnatural pronunciation. There is a possibility of becoming.

  Patent Document 2 describes a mislegato process for preventing the sound from becoming unnatural during such legato performance, although it is different from the method using a plurality of assigners. In the miss legato process, when there is a note-off within the miss legato determination time from the note-on of the latest note that is being sounded, the part is assigned to the note and the sound is redone at that time.

  In this way, when a performance operation as shown in FIG. 19 is performed, if the period from KON3 to KOFF4 is within the mislegato determination time, the assignment can be redone at the KOFF4 timing. Sound generation corresponding to the three key depressions of high n1 to n3 can be performed.

  However, if reassignment is performed at the timing of KOFF4, when multiple parts are assigned to pitch n3, for each key press of pitch n3, the part that starts sounding with KON3 and the part that starts sounding with KOFF4 There will be. For this reason, two sounds are pronounced at a slightly shifted timing, which is not preferable for hearing. This point is particularly noticeable when a performance is performed in which the pitches change quickly (the time of one key press is short or there is a continuous pronunciation in a short time).

  The present invention has been made in view of such circumstances, and even when successive performance operations are partially overlapped, the pronunciation suitable for the intention of the player's performance operation is suppressed while suppressing adverse effects on hearing. The purpose is to make it easy.

In order to achieve the above object, an electronic musical instrument according to the present invention includes one or more selection means for selecting a pitch to be generated based on a predetermined rule in accordance with operation states of a plurality of operation units each corresponding to a pitch. The sounding selection history of the selection means by each of the selection means, and the predetermined rule for the selection means for which the selection history saved by the storage means satisfies a predetermined condition, is finally operated to start sound generation. And a control means for changing the priority of the operation unit to the late arrival priority.
In such an electronic musical instrument, it is preferable that the predetermined condition includes a change in pitch selected at a frequency equal to or higher than a predetermined reference within a predetermined period.

Another electronic musical instrument of the present invention includes one or a plurality of selection means for selecting a pitch to be generated based on a predetermined rule in accordance with operation states of a plurality of operation units each corresponding to a pitch, and each operation described above. A storage means for storing the operation history of a part, and a selection means in which the pitch to be selected in any of the plurality of operations fluctuates when a plurality of operations in the operation history stored by the storage means satisfy a predetermined condition And a control means for changing the predetermined rule to the priority of late arrival for selecting the pitch of the operation unit that has been operated to start the sound generation last.
In such an electronic musical instrument, when the predetermined condition is that a sound generation start operation is performed on a certain pitch operation unit and a sound generation stop operation is performed on another pitch operation unit within a predetermined time, the operation exceeds a predetermined standard. It is good to have done with the frequency of.
The present invention can be implemented as an apparatus, a program, a method, a system, or any other form.

  According to the electronic musical instrument, the program, and the tone pitch selection method of the present invention as described above, even when consecutive performance operations are partially overlapped, the performance operation intention of the performer is suppressed while suppressing adverse effects on the audibility. It is possible to make it easy to produce a suitable pronunciation.

Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
[First Embodiment: FIGS. 1 to 9]
FIG. 1 is a block diagram showing a hardware configuration of an electronic musical instrument which is an embodiment of the present invention.
As shown in FIG. 1, the electronic musical instrument 10 includes a CPU 11, a ROM 12, a RAM 13, a storage device 14, a communication interface (I / F) 15, a detection circuit 16, a display circuit 17, and a sound source circuit 18. Connected by. The electronic musical instrument 10 includes a timer 21 connected to the CPU 11, a performance operator 22 and setting operator 23 connected to the detection circuit 16, a display 24 connected to the display circuit 17, and a DAC (digital / analog conversion) connected to the tone generator circuit 18. Circuit) 25 and a sound system 26.

Then, the CPU 11 controls the entire electronic musical instrument 10 by executing a required program stored in the ROM 12 or the storage device 14 using the RAM 13 as a work area, thereby detecting the performance operation and responding to the operation state of the performance operator. Various functions such as selection of pronunciation pitch and control of pronunciation according to the selection are realized. A timer 21 connected to the CPU 11 supplies a basic clock signal, interrupt processing timing, and the like to the CPU 11.
In addition to the above programs, the ROM 12 also stores various data files such as waveform data corresponding to timbre, automatic performance data, automatic accompaniment data (accompaniment style data), various parameters, various tables, and the like.

The RAM 13 is used as a buffer area such as a reproduction buffer in addition to the work area of the CPU 11 that stores flags, registers, various parameters, and the like.
The storage device 14 is composed of at least one of a combination of a recording medium such as a hard disk or a semiconductor memory and a driving device thereof.
The communication I / F 15 is an interface for communicating with an external device such as a server, an audio device, an external controller, and the like, and can be configured using communication means of any standard regardless of wired or wireless. For example, it is possible to use USB (Universal Serial Bus) or MIDI (Musical Instrument Digital Interface) _I / F.

The detection circuit 16 is an interface for connecting the performance operator 22 and the setting operator 23 to the system bus 19.
The performance operator 22 is connected to the detection circuit 16 and supplies performance information (performance data) according to the performance operation of the user. The performance operator 22 includes a plurality of operation units each corresponding to a pitch for receiving a user's performance operation. Then, the operation start timing and end timing for the operation unit of the user are supplied to the CPU 11 through the detection circuit 16 as key-on data and key-off data including pitch information corresponding to the operation unit operated by the user. The performance operator 22 can also supply various parameters such as a velocity value in accordance with a user's performance operation. In the present embodiment, the description will be made assuming that the keyboard-type performance operation element 22 is provided and each operation unit is a key. However, the present invention is not limited to this.

The setting operator 23 may be any device that can output a signal corresponding to a user input, such as a button, a slider, a rotary encoder, a character input keyboard, and a mouse. The setting operator 23 may be a pointing device for performing an operation on a GUI (Graphical User Interface) displayed on the display 24 or a touch panel stacked on the display 24.
In any case, the user can perform various inputs, settings, and selections using the setting operator 23.

The display circuit 17 is an interface for connecting the display 24 to the system bus 19.
The display 24 is a display means for displaying various information for setting the electronic musical instrument 10, an operation state of the electronic musical instrument 10, and the like, and can be configured by, for example, a liquid crystal display device, a light emitting diode (LED), or the like. .

  The tone generator circuit 18 has a function of generating musical tone signals (digital waveform data) using a plurality of tone generation channels (channels) in response to a tone generation instruction from the CPU 11. The sound generation instruction from the CPU 11 includes designation of tone color, pitch, volume, and the like. When the CPU 11 detects the performance operation of the performance operator 22, the assigner function selects the pitches for sounding corresponding to the assigners from the pitches of the keys being pressed, and follows the selection. The tone generator circuit 18 is instructed to generate the sound. Details thereof will be described later.

  The sound source circuit 18 is a waveform data, audio data, automatic accompaniment data, automatic performance data recorded in the storage device 14, ROM 12 or RAM 13, etc., or a performance supplied from an external device connected to the communication I / F 15 or the like. It is also possible to generate a musical sound signal according to a signal, MIDI signal, phrase waveform data, and the like. The tone generator circuit 18 also has a function of adding various musical effects to the generated musical sound signal.

The tone generator circuit 18 outputs the generated musical sound signal to the DAC 25. The DAC 25 converts the musical sound signal into an analog acoustic signal and supplies it to the sound system 26 connected to the DAC 25. The sound system 26 is sound generation means including an amplifier and a speaker, and outputs an analog sound signal supplied from the DAC 25. The DAC 25 and the sound system 26 may be outside the electronic musical instrument 10.
In the electronic musical instrument 10 described above, a characteristic point is related to the operation of the assigner. Therefore, the operation of the assigner will be described more specifically.

FIG. 2 is a functional block diagram of functions related to sound generation control using the assigner in the electronic musical instrument 10.
As shown in FIG. 2, the electronic musical instrument 10 includes a sound generation instruction receiving unit 31, an operation state detection unit 32, an assignment control unit 33, a musical sound generation unit 34, a selection history storage unit 35, a late arrival priority setting unit 36, and an output unit 37. Is provided. Among these, the function of the sound generation instruction receiving unit 31 is realized by the performance operator 22 and the detection circuit 16, the function of the musical tone generation unit 34 is realized by the sound source circuit 18, and the function of the output unit 37 is realized by the sound system 26. The The functions of other units are realized by the CPU 11.

  The sound generation instruction receiving unit 31 has a function of receiving a sound generation instruction operation by the user. For example, when the keyboard as the performance operator 22 receives a key pressing operation (pronunciation start operation) of any key, the sound generation instruction receiving unit 31 detects this, and the operation state detecting unit 32 performs the key pressing operation. Key-on data, which is an operation signal indicating that there is a note and the note number that is the pitch of the pressed key, is transmitted. When a key release operation (pronunciation stop operation) is accepted, similarly, key-off data indicating that there has been a key release operation and the note number of the key is transmitted.

  In the following description, an operation for instructing the start of sound generation such as a key press is referred to as a “key-on operation”, and an operation for instructing a stop of sound generation such as a key release is referred to as a “key-off operation”. A state from the key-on operation to the key-off operation is referred to as “in operation”. Speaking of the keys on the keyboard, “Now pressing” corresponds to this. However, even when a sounding start instruction is given, sounding is not always started. This is because it is possible to make a setting that does not generate sound for a certain pitch, or to limit the number of simultaneous sounds.

  The operation state detection unit 32 detects the current operation state of the performance operator 22 (here, the key is pressed because it is a keyboard) based on the operation signal transmitted from the sound generation instruction reception unit 31. More specifically, the pitch of the key being operated is obtained. This key depression state can be obtained, for example, by adding the note number included in the key-on data to the list of operating pitches and deleting the note number included in the key-off data from the list of operating pitches. it can.

  When the key-on data is received, the operation state detection unit 32 supplies information on the detected operation state to the assignment control unit 33, and selects a pitch to be generated. A specific supply destination is an assigner whose function is valid among n assigners from the first assigner AS-1 to the nth assigner AS-n included in the allocation control unit 33.

When a person performs, even if he intends to operate a plurality of keys at the same time, it is difficult to perform the operation at the same timing without any difference. Therefore, if the timing difference between a plurality of operations is within a predetermined threshold (for example, about 15 to 30 milliseconds) that can be regarded as simultaneous operations, it is desirable to treat those operations as being performed at the same time. Here, explanation will be made assuming that this is handled. A key-on operation for one key and a key-off operation for another key may be performed simultaneously.
Further, the operation state detection unit 32 has a function of causing the tone generation unit 34 to stop the sound generation of the pitch for which the key-off operation has been performed when key-off data is received.
In addition, the operation state detection unit 32 has a function of transmitting the fact to the late arrival priority setting unit 36 when key-on data is received.

  Next, the allocation control unit 33 includes one or a plurality (here, n) of assigners AS-1 to AS-n (use the code “AS” when there is no need to specify an individual of the assigner). . Each of these assigners AS, according to the operation state information of the performance operator 22 supplied from the operation state detection unit 32 according to the key-on operation, from the pitch of the operation (during key depression) from the musical tone. This is a selection means for selecting a pitch (note) to be generated by the generation unit. This selection is performed according to a rule set for each assigner.

FIG. 3 shows an example of rules set for the assigner.
FIG. 3 shows an example in which four assigners are used, and a rule set for each assigner includes items of “target key press” and “priority method”. The item “explanation” is an explanation for helping understanding of the contents of the rules defined by the information of these items, and is not used for the selection process.

  The target key-pressing item is an item that determines which range of pitches during key pressing should be considered as a selection target. “Full key press” indicates that all pitches during key press are considered. “Low-pitched side X sound” indicates that only X pitches from the low-pitched side among the pitches being pressed are considered. However, if the number of key presses is less than X, all the pitches during key press are considered. Further, although not shown in FIG. 3, “high-side X sound” can be similarly set.

  The item of the priority method is an item that determines how to select a pitch to be generated among the pitches considered as a selection target. “High pitch priority” indicates that the highest pitch among the pitches to be considered is selected. “Low-tone priority” indicates that the lowest pitch among the pitches to be considered is selected.

From the above, it can be seen that for the first assigner, a rule for selecting the highest pitch among all pitches being pressed is set.
For the second assigner, if the number of key presses is 3 or less, the highest pitch among the key presses is selected. If the number of key presses is 4 or more, the highest pitch among the three low-pitched sounds, that is, the third pitch from the bottom is selected.
Similarly, for the third assigner, if the number of key presses is 2 or less, the highest pitch among the key presses is selected. If the number of key presses is 3 or more, the second pitch from the bottom is selected. Will do.
It can be seen that for the fourth assigner, a rule for selecting the lowest pitch among all pitches being pressed is set.
For assigners not shown in the figure, it can be considered that the function is disabled.

When each assigner AS selects a pitch to be pronounced according to the above rules, the assigner AS requests the tone generator 34 to start the tone having the selected pitch. Each assigner AS is set with a corresponding tone color T1 to Tn, and requests that a musical tone be generated with the corresponding tone color. It is also possible to set a corresponding part in the assigner AS and set the timbre in association with the part. In this case, the assigner AS and the timbre are associated with each other through the part, and the part associated with the assigner AS-n is represented as the nth part.
Further, when each assigner AS selects another pitch while a certain pitch is selected, the assigner AS requests the tone generation unit 34 to stop generating the tone having the selected pitch. .

  Each assigner AS holds information about which pitch is the last selected pitch until it selects another pitch next time. Even when the pitch is selected, the selected pitch does not change from the previously selected pitch, and the pitch is not the pitch that was key-oned this time (it was being operated before). In this case, it is preferable not to make a request for sound generation to the musical tone generation unit 34. In this case, for the pitch selected by the assigner AS this time, it is considered that it is desirable to continue the pronunciation started in response to the previous key-on operation regardless of the key-on operation detected this time.

  Further, every time the pitch selected by each assigner AS varies, the allocation control unit 33 supplies the information to the selection history storage unit 35 together with information on the time at which the variation occurred, and stores the information. Here, “the pitch to be selected fluctuates” means that a pitch has been selected so that a tone generation request to the musical tone generation unit 34 needs to be made. That is, a case where a pitch different from the previous pitch is selected, or a pitch that is keyed on this time even if the pitch is the same as the previous pitch is applicable. In the latter case, the corresponding pitch should have been keyed off and then on again, and in this case, it can be considered that the selection of the pitch has been canceled and then selected again.

In this example, it is assumed that each assigner selects one pitch for the sake of simplicity, but it is also possible to set a rule capable of selecting a plurality of pitches. Select two tones with priority on high tones, etc.
There is no problem even if a plurality of assigners select the same pitch. In this case, the selected pitch is pronounced with a plurality of timbres.

  The musical sound generation unit 34 includes m sound generation chTC1 to TCm (use the code “TC” when there is no need to specify an individual sound generation ch). When a request to start sounding is received from the assigner AS, a sounding channel that is not sounding is searched, and a sound signal of the tone and tone color specified in the sounding start request is generated by using the found sounding chTC (sounding). Let In FIG. 2, the assigner AS and the sounding chTC are connected by a line, but there is no fixed correspondence between them.

In addition, when the operation state detection unit 32 instructs the musical sound generation unit 34 to stop generating a specific pitch, the musical sound generation unit 34 searches the pronunciation chTC for the one that is generating the pitch, It also has a function to stop the pronunciation of the pronunciation channel. In addition, when any of the assigners AS is instructed to stop the sound generation of a specific pitch, the sound of the pitch is generated by the part associated with the requesting assigner AS from the sound generation chTC. It also has a function of searching for what is being recorded and stopping the pronunciation of the pronunciation. These outages include a transition to a released state.
Then, the musical sound generation unit 34 mixes the acoustic signals generated by the respective sound generation chTCs and supplies them to the output unit 37 to output musical sounds.

Next, the selection history storage unit 35 is a storage unit having a function of storing, as a selection history of pitches, information on changes in pitch selection by each assigner AS and the time of occurrence thereof supplied from the assignment control unit 33. is there.
FIG. 4 shows an example of a selection history table used by the selection history storage unit 35 for storing the selection history.
As shown in FIG. 4, the selection history table is a table for recording, in time series, which pitch the assigner has selected at which timing for the assigner enabled in the allocation control unit 33. .

In the example of FIG. 4, it is registered that the first assigner has selected the pitch nm1 at the time KON1, selected the pitch nm2 at the time KON2, and selected the pitch nm3 at the time KON3. Note that it is not essential to register the time of deselection, but it may be registered. Further, as described above, even if the assigner AS selects a pitch in response to a key-on operation, if the pitch selection does not change, the pitch selection is not registered in the selection history.
This point will be described in detail later using a specific performance operation and an example of pitch selection according to the operation. Further, the operation history table may be stored in the RAM 13, for example. However, it can be stored in any storage means including those external to the electronic musical instrument 10.

Returning to the description of FIG.
The late arrival priority setting unit 36 refers to the selection history stored in the selection history storage unit 35 at an appropriate timing (for example, the timing at which a key-on operation is detected), and the assigner AS whose selection history satisfies a predetermined condition is referred to. , A control means having a function of setting that the pitch selection rule used by the assigner AS is to be given priority on the arrival. This late arrival priority replaces both the target key depression and the priority method shown in FIG. Then, the assigner AS that decides to use the late arrival priority selects the pitch of the key that was last key-on among all the keys being pressed, regardless of the rules set in FIG. become.

  Here, “there was a change in pitch to be selected with a frequency equal to or higher than a predetermined reference within a predetermined period” as the “predetermined condition”. It is considered that the assigner AS satisfying this condition continuously selects a pitch for which a key-on operation related to a performance in which the pitches are quickly switched (the time of one key depression is short) is performed. When performing such a performance, even if not intended, the key release of the previous key becomes slower than the key press of the next key, and as shown by the pitch n3 and pitch n4 described with reference to FIG. It is easy for part of the key timing to overlap.

  Therefore, by making the assigner AS responsible for sound generation related to such performance use the late arrival priority rule, it is possible to reliably start sound generation at the timing of the key-on operation, regardless of whether or not the key press timing is overlapped. Further, even when a plurality of assigners AS select a pitch related to the same key-on operation based on different rules, the sounding start timing is not shifted for each assigner AS.

  The predetermined period is, for example, 800 milliseconds, and the predetermined reference frequency is, for example, four times within the predetermined time. This is because if the pitch length of the eighth note at tempo 150 is 200 milliseconds and the pitches are switched more frequently than this, the start timing shift for each assigner AS is noticeable.

Further, a condition for returning the pitch selection rule of the assigner AS once set to use the late arrival priority to that shown in FIG. 3 is also set separately. For example, the assigner AS that is set to use the later arrival priority that returns to the original state after a predetermined time has elapsed after setting to use the later arrival priority has entered a state in which no pitch is selected (by a key-off operation or the like). In some cases, it may be possible to restore the original.
Alternatively, it may be possible to restore the operation history of the relevant assigner AS when the operation history of the assigner AS no longer satisfies the predetermined condition used when setting to use late arrival priority. The pitch frequency to be selected falls below a predetermined standard, and so on. This is to determine whether or not a predetermined condition is satisfied for each assigner AS at an appropriate timing, and if satisfied, a setting using the late arrival priority is performed, and if not satisfied, the original rule is used without using the late arrival priority. It corresponds to doing.

  The selection history storage unit 35 continues to store the selection history regardless of whether or not the late arrival priority setting unit 36 is set to use the late arrival priority (however, the history before the predetermined period is deleted). You may). Therefore, even if the pitch selection rule is restored, if the selection history at that time satisfies the predetermined condition, the setting for using the late arrival priority is immediately made again.

Next, an example of pitch selection by the assigner AS in the electronic musical instrument 10 in consideration of the functions of the selection history storage unit 35 and the late arrival priority setting unit 36 will be described with reference to FIG.
In FIG. 5, as in FIG. 19, the vertical axis represents time, the horizontal axis represents pitch, and the band at each pitch indicates the period during which the key of that pitch is depressed. Moreover, the arrow shown in the belt | band | zone shows whether each assigner has selected the pitch and is performing the corresponding pronunciation. The base of the arrow indicates the start of sound generation, and the tip indicates the sound stop timing.
An arrow T1 indicates “predetermined time” used by the late arrival priority setting unit 36 based on KON3. In the example of FIG. 5, for convenience of illustration, the predetermined standard of the frequency used by the late arrival priority setting unit 36 is two pitch fluctuations within this predetermined time.

  In the example of FIG. 5, at the first KON1 timing, keys of three pitches n1, n2, and nm1 are pressed simultaneously. After that, the keys of the pitches n1 and n2 are continuously pressed, and the keys of the pitches nm1 to nm5 are sequentially pressed during that time. Further, there is a little space between the key release at pitch nm1 and the key press at pitch nm2, and the key press timings of other key presses partially overlap.

In this case, at the timing of KON1, each assigner AS selects a pitch to be generated according to the rules shown in FIG. 3 while the keys of three pitches n1, n2, and nm1 are being pressed. As a result, the first assigner AS-1 and the second assigner AS-2 have the highest note nm1, the third assigner AS-3 has the second lowest n2, and the fourth assigner AS-4 has the lowest note n1. The tone generator 34 is selected to start sounding.
Then, the selection history storage unit 35 stores the time KON1 and the pitch information selected by the first to fourth assigners at that time, as in the first row of the selection history table of FIG.

  At the next KOFF1 timing, the first assigner AS-1 and the second assigner AS-2 that have selected the pitch nm1 according to the key release of the pitch nm1 cancel the selection of the pitch nm1, and the musical tone The generation unit 34 stops the sound generation.

  At the next KON2 timing, the key of the pitch nm2 is pressed. At this time, since no assigner has performed pitch selection only once in the past, this does not correspond to the “predetermined condition” for which the late arrival priority should be set. Accordingly, each of the assigners AS selects a pitch to be generated according to the rules shown in FIG. 3 in a state where the three pitch keys n1, n2, and nm2 are being pressed. As a result, the first assigner AS-1 and the second assigner AS-2 select the highest tone nm2, and the third assigner AS-3 and the fourth assigner AS-4 select n2 and n1, respectively.

  Then, as shown in the second row of the selection history table in FIG. 4, the selection history storage unit 35 selects the first assigner AS-1 and the second assigner AS-2 that have changed the pitch selection at this time. Saves information about time KON2 and the pitch selected at that time. In addition, the first assigner AS-1 and the second assigner AS-2 cause the tone generator 34 to start sounding the corresponding pitch. For the third assigner AS-3 and the fourth assigner AS-4, there is no change in pitch selection (no new pronunciation is started), so no history is added.

  At the next KON3 timing, the key with the pitch nm3 is pressed. At this point in time, the first assigner AS-1 and the second assigner AS-2 have the selected pitch changed twice within the predetermined period indicated by the arrow T1, and therefore, the "predetermined condition" It corresponds to. On the other hand, the third assigner AS-3 and the fourth assigner AS-4 do not correspond to the “predetermined condition” because the change in the selected pitch within the predetermined period is only once at the time of new selection. Therefore, the late arrival priority setting unit 36 performs setting using the late arrival priority rule only for the first assigner AS-1 and the second assigner AS-2.

  At the timing of KON3, the pitches generated by each assigner AS are selected while the four pitch keys n1, n2, nm2, and nm3 are being depressed. Here, since the first assigner AS-1 and the second assigner AS-2 perform selection with priority on the last arrival, the last pitch key nm3 is selected and the musical tone generation unit 34 selects the previous one. The sound generation of the tone pitch nm2 is stopped and the sound generation of the newly selected pitch nm3 is started. The third assigner AS-3 and the fourth assigner AS-4 select pitches according to the rules shown in FIG. 3, and select n2 and n1 as before.

  Then, as shown in the third row of the selection history table in FIG. 4, the selection history storage unit 35 selects the first assigner AS-1 and the second assigner AS-2 that have changed the pitch selection at this time. Saves information about time KON3 and the pitch selected at that time. FIG. 4 shows the state of the selection history table at this KON3 timing. For the third assigner AS-3 and the fourth assigner AS-4, since there is no change in the selection of the pitch, the history is not added and the pronunciation is not started.

  At the next KOFF2 timing, the key of pitch nm2 is released, but since no assigner has selected pitch nm2 at this time, this key release does not affect the pitch selection of each assigner. .

Thereafter, until the timing of KOFF5, for the first assigner AS-1 and the second assigner AS-2, in each key-on (KON4, KON5), the condition that the selected pitch fluctuates more than the reference number during the immediately preceding predetermined period T1. Therefore, the condition for returning the pitch selection rule to the original condition is not satisfied, and the late arrival priority is maintained.
In this case, the first assigner AS-1 and the second assigner AS-2 each have a pitch according to the key press of the key with the pitch of nm4 at the timing of KON4 and the key press of the key with the pitch of nm4 at the timing of KON5. nm4 and pitch nm5 are selected, and the tone generator 34 stops the pronunciation of the pitch selected so far and starts the pronunciation of the newly selected pitch.
For the third assigner AS-3 and the fourth assigner AS-4, the pitches to be selected do not change much, so in the example of FIG. 5, the “predetermined condition” for setting the late arrival priority is not satisfied.

  As described above, in the electronic musical instrument 10, by the functions of the selection history storage unit 35 and the late arrival priority setting unit 36, a key depression operation with a partial period overlapped like the pitches nm2 to nm5 in FIG. 5 is performed, and When a plurality of assigners AS should select a pitch related to the key press, the plurality of assigners AS can simultaneously select the pitch related to the key press at the timing of the key press. Accordingly, as described with reference to FIG. 19, the timbre is not changed every time the key is pressed or the sounding start timing is not shifted for each part, and the adverse effect on the audibility is suppressed, and the performance operation of the performer is intended. Proper pronunciation can be performed easily.

If the first-come-first-served priority is always used, the assigner setting shown in FIG. 3 is completely ignored, and this does not result in a performance that matches the intention of the performer. Therefore, it is effective to set the late arrival priority by discriminating the assigners effective for setting the late arrival priority and the timing thereof based on the “predetermined condition” as described above.
Further, depending on the setting of “predetermined conditions” (for example, when a predetermined reference of frequency is set to four pitch fluctuations within a predetermined time), there is a change in tone color or a difference in sound generation timing for several key presses. Although this may occur, it is still possible to suppress an adverse effect on the audibility and to produce a sound suitable for the intention of the player's performance operation, compared to the case where the priority is not given to the last arrival.

Next, processing executed by the CPU 11 in order to realize the function performed by the CPU 11 among the functions shown in FIG. 2 will be described.
FIG. 6 to FIG. 8 are flowcharts of processing when key-on data and / or key-off data are received.
When the CPU 11 receives key-on data and / or key-off data from the detection circuit 16, the CPU 11 starts the processing shown in the flowchart of FIG. 6 by executing a required program. As described above, an operation performed with a timing difference within a predetermined threshold is regarded as a simultaneous operation.

In the process of FIG. 6, the CPU 11 first determines whether or not the detected operation includes a key-on operation (S11). If a plurality of operations are detected at the same time, the answer is Yes if there is even one key-on operation.
In the case of Yes, if there is a key-off operation in the detected operation (Yes in S12), the CPU 11 instructs the musical sound generation unit 34 to stop the pitch generation related to the key-off operation (S13). Thereafter, the quick play determination process shown in FIG. 7 corresponding to the function of the late arrival priority setting unit 36 is performed (S14).

  In the process of FIG. 7, the CPU 11 first assigns 1 to a variable n (S21). Then, with reference to the selection history stored by the selection history storage unit 35, it is determined whether or not the pitch selected by the nth assigner fluctuates at a frequency equal to or higher than a predetermined reference within the most recent predetermined period (S22). That is, it is determined whether or not the pitch selection history by the nth assigner AS-n satisfies a “predetermined condition” in which the pitch selection rule is to be given priority on the last arrival.

If YES in step S22, a late arrival priority flag is set for the nth assigner AS-n (S23). This flag is a flag indicating that the pitch selection rule for the assigner is given priority to later arrival. If No in step S22, the process proceeds to the next process without changing the flag.
In either case, the CPU 11 next determines whether or not the currently assigned assigner is the last assigner (S24). If not, the CPU 11 increments n by 1 (S25), and returns to step S22 for processing. repeat.

In the case of Yes in step S24, it can be seen that the processing related to all assigners has been completed, so the processing in FIG. 7 is terminated and the original processing is returned.
Here, it returns to step S15 of FIG. Then, the CPU 11 sets a sound generation assignment flag for all the assigners AS in order to select a sound generation pitch according to the key-on operation by the assigner AS (S15), and proceeds to the sound generation assignment process shown in FIG. 8 (S16).

In the process of FIG. 8, the CPU 11 first assigns 1 to a variable n (S31). Then, it is determined whether or not the sound generation assignment flag is set in the nth assigner AS-n (S32).
If it is set here, the CPU 11 next determines whether or not the late arrival priority flag is set in the nth assigner (S33). If “No”, the CPU 11 selects a pitch to be generated from the pitches of the key being operated in accordance with the rules set for the nth assigner AS-n (S34). On the other hand, if Yes in step S33, the CPU 11 selects a pitch to be generated from the pitches of the key being operated in accordance with the rules for priority on arrival (S35).

In any case, it is determined whether the nth part corresponding to the nth assigner AS-n is sounding at the pitch selected in step S34 or S35 (S36). If the answer is No, it is understood that the selected pitch fluctuates the selected state of the pitch, and the pitch selection history is recorded and a new pronunciation should be started.
Therefore, the CPU 11 stores the selected pitch and its timing in the selection history table shown in FIG. 4 (S37). Further, the musical sound generation unit 34 is instructed to start sounding the nth part corresponding to the nth assigner AS-n at the selected pitch (S38). In this case, the timbre used for sound generation is the timbre set for the nth part.

If “Yes” in step S36, it is understood that the current selection does not change the selection state of the pitch, and it is not necessary to record the selection history of the pitch and to start a new pronunciation. Therefore, steps S37 and S38 are skipped and the process proceeds to the next process.
If No in step S32, no pitch is selected for the nth assigner, and the process directly proceeds to step S39.

The above steps S32 to S38 are processing for one assigner AS. Thereafter, the CPU 11 determines whether or not the currently assigned assigner is the last assigner (S39). If not, the CPU 11 increments n by 1 (S40), and returns to step S32 to repeat the process.
In the case of Yes in step S39, since it can be seen that the processing relating to all assigners has been completed, the processing in FIG. 8 is terminated and the original processing is returned. Here, since the process returns to step S16 in FIG. 6, the CPU 11 ends the process as it is. When the process proceeds from step S15 to step S16, the pitch selection and the sound generation instruction corresponding to all the assigners are performed in the sound generation assignment process.

  Before starting the processing of FIG. 8, the sound assignment flag of all assigners may be confirmed first, and steps S33 to S38 may be executed only for those assigners with flags. In this case, if there is no assigner with a flag, the pronunciation assignment process itself can be skipped.

On the other hand, in the case of No in step S12 of FIG. 6, that is, when the detected operation is only a key-off operation, the CPU 11 instructs the musical tone generation unit 34 to stop the tone generation related to the key-off operation (S17). .
Thereafter, the process proceeds to the sound generation assignment process of FIG. 8 (S16). However, since no sound assignment flag is set for any of the assigners, the process ends without recording the selection history or starting the sound generation. Therefore, in this case, the pronunciation assignment process itself may be skipped as described above.
With the above processing, the pronunciation as described with reference to FIG. 5 becomes possible.

Next, FIG. 9 shows a flowchart of processing relating to cancellation of the late arrival priority flag.
The CPU 11 starts processing shown in the flowchart of FIG. 9 at an appropriate timing. This timing may be arbitrary, such as a timing for executing the processing of FIG.
In the first embodiment, it is preferable to use “the predetermined condition used when setting to use late arrival priority is no longer satisfied” as the release condition of the late arrival priority flag. And when using this cancellation | release condition, it is preferable to also perform the process of FIG. 9 at the timing which performs the process of FIG.

  In the process of FIG. 9, the CPU 11 first assigns 1 to a variable n (S51). Then, it is determined whether or not a late arrival priority flag is set in the nth assigner AS-n (S52). In the case of Yes, it is determined whether or not a condition for canceling the late arrival priority flag (condition for stopping the late arrival priority and returning to the original rule) is satisfied for the nth assigner AS-n (S53). Specific examples of the conditions used here are as described above.

If YES in step S53, the CPU 11 cancels the late arrival priority flag for the nth assigner AS-n, and thereafter selects the pitch according to the rule set for the assigner (S54).
In the case of No in step S52, there is no matter to be considered here for the nth assigner AS-n, so steps S53 and S54 are skipped and the process proceeds to step S55.
In the case of No in step S53, it is not necessary to cancel the late arrival priority flag, so step S54 is skipped and the process proceeds to step S55.

In either case, the CPU 11 next determines whether or not the currently assigned assigner is the last assigner (S55). If not, the CPU 11 increments n by 1 (S56), and returns to step S52 for processing. repeat.
In the case of Yes in step S55, since it is found that the processing related to all assigners has been completed, the processing in FIG. 9 is terminated.
With the above processing, the CPU 11 can restore the pitch selection rule at an appropriate timing for the assigner AS that is set to use the late arrival priority.

[Comparative example of the first embodiment: FIG. 10]
Next, the effect of using late arrival priority will be described using the comparative example of FIG.
FIG. 10 shows an example of pitch selection by each assigner AS when the same key operation as in FIG. 5 is performed, assuming that the same assigner as in the first embodiment is used and there is no late arrival priority setting unit 36. FIG.
In this case, the pitch selection by each assigner AS is the same as in the case of FIG. 5 until the timing of KON2.

However, at the timing of KON3, all the assigners AS select the pitches according to the rules shown in FIG. 3 while the four pitch keys n1, n2, nm2, and nm3 are being pressed. Therefore, the first assigner AS-1 has the highest tone nm3, the second assigner AS-2 has the third nm2 from the bottom, the third assigner AS-3 has the second n2 from the bottom, and the fourth assigner AS-. 4 selects n1 of the lowest sound.
In this case, since the pitch to be selected by the first assigner AS-1 varies from nm2 to nm3, the musical tone generator 34 starts a new pronunciation, but the pitches to be selected by other assigners do not vary. Does not start proper pronunciation.

  At the next timing of KOFF2, the key of the pitch nm2 is released, and the tone generator 34 stops the sound generation of the second assigner AS-2 that has selected the pitch nm2. At this time, the sound corresponding to the second assigner AS-2 is not performed.

  At the timing of the next KON4, all assigners AS are shown in FIG. 3 with the key of the pitch nm4 being pressed and the keys of the four pitches of n1, n2, nm3, and nm4 being pressed. Select the pitch according to the rules. Therefore, the first assigner AS-1 has the highest tone nm4, the second assigner AS-2 has the third nm3 from the bottom, the third assigner AS-3 has the second n2 from the bottom, and the fourth assigner AS-. 4 selects n1 of the lowest sound.

In this case, since the pitch to be selected by the first assigner AS-1 varies from nm3 to nm4, the musical tone generation unit 34 starts a new pronunciation. The second assigner AS-2 also causes the tone generator 34 to start a new pronunciation in order to newly select the pitch nm3.
However, the sound generation of the second assigner AS-2 is stopped when the key having the pitch of nm3 is released at the timing of KOFF3 immediately after that. The same thing occurs when the key is pressed at the next pitch nm5 and the key is released at the pitch nm4.

  As described above, when the function of the late arrival priority setting unit 36 is not provided, if there is a partially depressed key pressing operation as shown in FIG. 10, the pitch order of the pressed keys and the assigners are The relationship with the selected pitch will deviate. That is, from the performance operation, it is possible to guess the intention to continuously generate the sounds from the pitch nm1 to the pitch nm5, but these pitched sounds are pronounced in different tones, resulting in an unnatural pronunciation. End up. In this example, the pitches nm1 and nm2 are pronounced by the timbres of the first assigner AS-1 and the second assigner AS-2, while the pitches nm3 to nm5 are substantially assigned to the assigner AS-1. It will sound only with the tone of.

  On the other hand, by using the function of the late arrival priority setting unit 36, such a problem does not occur, and even if the key depression from the pitch nm1 to the pitch nm5 partially overlaps or there is a gap, As described above, it is possible to produce a sound without changing the tone color for each key press and without shifting the sound generation start timing for each part.

[Second Embodiment: FIGS. 11 to 15]
Next, an electronic musical instrument according to a second embodiment of the present invention will be described.
In the second embodiment, instead of changing the pitch selection rule to the last arrival priority for an assigner whose pitch selection history satisfies a predetermined condition, the predetermined condition is set in the operation history of the performance operator. The only difference from the first embodiment is that when a satisfying operation is detected, the pitch selection rule is changed to the late arrival priority for the assigner whose pitch selected at the time of the operation varies. Therefore, only this difference will be described, and the same reference numerals as those in the first embodiment are used for the same or corresponding components as those in the first embodiment.

The electronic musical instrument 10 of the second embodiment has the same hardware as that of the first embodiment shown in FIG.
FIG. 11 is a functional block diagram corresponding to FIG. 2 in the electronic musical instrument 10 of the second embodiment.
As shown in FIG. 11, the electronic musical instrument 10 of the second embodiment includes an operation history storage unit 38 instead of the selection history storage unit 35 in the first embodiment, and further includes a key-off retrigger control unit 39. Further, the condition that the late arrival priority setting unit 36 sets the assigner's pitch selection rule as the late arrival priority is also different.

  In the electronic musical instrument 10, the operation state detection unit 32 supplies the operation content and operation timing information to the operation history storage unit 38 each time an operation of the performance operator 22 is detected, and stores the operation content history. The operation history storage unit 38 is a storage unit having a function of storing the operation contents and operation timing information supplied from the operation state detection unit 32 as the operation history of the performance operator 22 in time series.

FIG. 12 shows an example of an operation history table used by the operation history storage unit 38 to store an operation history.
As shown in FIG. 12, the operation history table is a table for registering the contents of operations performed on the performance operator 22 in association with the times.
If a plurality of operations are performed simultaneously, a plurality of operations may be registered at the same time. Further, although the time is indicated by a sign in FIG. 12, not only the order but also a specific time (may be an elapsed time from a predetermined reference time) is registered.
This operation history table may be stored in the RAM 13, for example. However, it can be stored in any storage means including those external to the electronic musical instrument 10.

Returning to the description of FIG. 11, when the operation state detection unit 32 detects a key-off operation of the performance operator 22, the operation state detection unit 32 notifies the key-off retrigger control unit 39 of this.
In response to this notification, the key-off retrigger control unit 39 selects the pronunciation pitch at the allocation control unit 33 according to the current key-off operation based on the information in the operation history table created by the operation history storage unit 38. A function is provided for determining whether or not it is necessary to perform the operation. When it is determined that it is necessary to perform this, the assignment control unit 33 is instructed to select a pronunciation pitch.
In this manner, letting the assigner AS select the tone pitch according to the key-off operation is referred to as “key-off retrigger”.

The key-off retrigger is performed in order to prevent a certain note from being reduced by muting a key-off operation. Typically, as in the case of n4 and n3 in FIG. 19, it is considered that the intention is to play two sounds in succession, but the operation period of the previous key and the subsequent key is slightly overlapped. Yes.
In this case, if the pitch of the pitch n4 is stopped at the timing of KOFF3 after the pitch of the pitch assigned by each assigner AS is selected at the timing of KON3, the tone corresponding to the assigner AS having selected the pitch n4 at the timing of KON3. Will disappear immediately. However, although it cannot be determined at the timing of KON3, in the operation shown in FIG. 19, the key of pitch n4 is not key-off operated at the timing of KON3 because it is not necessary to increase the sound at that part and then decrease it. Conceivable. Therefore, it can be said that the pitch n4 should not be considered when the assigner AS selects the pitch at the timing of KON3.

  Therefore, the key-off retrigger control unit 39 determines whether or not the overlap between the operation periods of n4 and n3 is intended for sound overlap at the timing of KOFF4 when the key of the pitch n4 is key-off operated. The function to judge according to the conditions is provided. In addition, when it is determined that the duplication is not intended, the assigner AS is provided with a function of selecting a pitch to be regenerated (performing key-off retrigger) according to the operation state after n4 key release.

  However, at this time, the pitch is selected only by the assigner AS that has selected the pitch (n4 in the example of FIG. 4) whose sound generation has been stopped in response to the key release. The pitches selected by other assigners AS have already begun to sound at the timing of KON3. If the pitch selection is changed at the timing of KOFF4, the pitch will change in a short time. It is because it ends up.

  When performing the key-off retrigger, the key-off retrigger control unit 39 may specify the pitch and instruct the assignment control unit 33 to reselect the pitch to be generated. In response to this instruction, the assignment control unit 33 searches for the assigner AS that has selected the designated pitch, and determines the assigner AS that is to select the pitch. In the search, information on the selected pitch held by the assigner AS is used. The selection of the pitch in the determined assigner AS and the processing of the sound generation start request to the tone generation unit 34 are the same as in the case of the selection according to the instruction from the operation state detection unit 32.

By the way, in this embodiment, when the key-off retrigger control unit 39 determines that a certain key-off operation is an operation related to the legato playing technique, the key-off retrigger control unit 39 causes the assignment control unit 33 to select a sound pitch according to the key-off operation. It is determined that it is necessary.
The legato playing method is a playing method in which a key that was previously pressed is released immediately after a certain key is pressed. For example, after a key-on operation at a certain pitch, When there is a pitch key-off operation, it can be said that the key-off operation is an operation related to the legato performance. This is a condition that the time from the most recent key-on operation to the current key-off operation is within a predetermined time considering the timing of the key-off operation.

In the case of the legato playing method, since the key that was pressed next is not normally released at the time when the key that was previously pressed is released, this point may be added to the condition. That is, the condition is that the key related to the most recent key-on operation is being operated at the time of the current key-off operation.
The key-off retrigger control unit 39 refers to the operation history table of FIG. 12 and performs the above-described key-off retrigger when it is determined that a certain key-off operation is an operation related to a legato performance based on the above conditions.

  Further, the key-off retrigger control unit 39 creates a legato history table as shown in FIG. 13 so that the late arrival priority setting unit 36 can grasp the assigner AS to set the late arrival priority in accordance with the conditions described later.

As shown in FIG. 13, the legato history table includes items of time, key-off operation, previous key-on operation, legato determination result, and presence / absence of selected pitch fluctuation for each assigner.
Among these, the time and operation contents of each key-off operation included in the operation history table are registered in the items of time and key-off operation.
In the most recent key-on item, the most recent key-on operation performed before the registered key-off operation is registered.
In the item of the legato determination result, it is registered whether or not the registered key-off operation and key-on operation are operations related to legato performance. “○” is legato, “×” is not legato. The four items so far can be considered as a history of operation contents of the performance operator 22.

  In the selection pitch change item, whether or not the pitch selected by the corresponding assigner has changed in accordance with the registered key-off operation or key-on operation is registered. “◯” indicates fluctuation, and “×” indicates no fluctuation. The key-off retrigger control unit 39 determines whether or not a legato performance is performed at the time of a key-off operation. Actually, a combination of the key-off operation and the previous key-on operation is a performance operation of the legato performance. Therefore, if the pitch of an assigner selected according to any of these changes, it can be considered that the assigner is the assigner responsible for the sound generation related to the performance of the legato performance.

  On the other hand, the late arrival priority setting unit 36 refers to the legato history table of FIG. 13 at an appropriate timing (for example, the timing at which a key-off operation is detected), and detects an operation satisfying a predetermined condition in the operation history. A control having a function for setting, as for the assigner AS whose pitch to be selected at the time of the operation, the priority for selecting the pitch used by the assigner AS is to be given priority as in the case of the first embodiment. Means.

Further, here, as the “predetermined condition”, an operation of performing a key-off operation of another pitch within a predetermined time after performing a key-on operation of a certain pitch (that is, a performance operation related to a legato playing method) It was performed with the above frequency.
In this manner, when the legato playing method is frequently (or continuously) performed, it is highly likely that the legato playing method will continue to a certain extent thereafter. Therefore, by making the assigner AS responsible for sound generation related to the performance of the legato performance use the late arrival priority rule, it is possible to reliably start sounding at the timing of the key-on operation regardless of whether or not the key pressing timing is duplicated. Further, even when a plurality of assigners AS select a pitch related to the same key-on operation based on different rules, the sounding start timing is not shifted for each assigner AS.

  Note that the assigner AS responsible for the sound generation related to the performance of the legato performance method can be considered to be the assigner AS in which the pitch selected in response to the performance operation of the legato performance method is changed. This is because an assigner AS in which the pitch to be selected does not change even if there is a performance operation is considered to be an assigner AS that produces a sound irrespective of the performance operation of the legato performance method, such as a key being pressed all the time.

In addition, here, the predetermined standard of the frequency is assumed to be “the key-off operation related to the legato playing method has been repeated a predetermined number of times (two times)”. However, the predetermined number of times is not two times, or m / n is a predetermined value (for example, 0.7) or more when m out of n previous key-off operations are the legato performance, and the key-off operation related to the legato performance is performed for a predetermined time. It is also possible to adopt other conditions, such as a predetermined number of times.
The release condition for returning the pitch selection rule of the assigner AS once set to use the late arrival priority to the one shown in FIG. 3 is the same as that in the first embodiment. However, a preferable release condition is different from that in the first embodiment, and this point will be described later.

Next, an example of pitch selection by the assigner AS in the electronic musical instrument 10 in consideration of the functions of the late arrival priority setting unit 36, the operation history storage unit 38, and the key-off retrigger control unit 39 will be described with reference to FIG.
FIG. 14 is a diagram corresponding to FIG. 5, and the notation is the same as FIG. 5. An arrow T2 indicates “predetermined time” used by the key-off retrigger control unit 39 based on KOFF1 and KOFF2.

In the example of FIG. 5, at the first KON1 timing, keys of three pitches n1, n2, and nm1 are pressed simultaneously. After that, the keys of the pitches n1 and n2 are continuously depressed, and during this time, the keys of the pitches nm1 to nm5 are sequentially pressed so that the key pressing timing partially overlaps.
In this case, at the timing of KON1, each assigner AS selects a pitch to be generated according to the rules shown in FIG. 3 while the keys of three pitches n1, n2, and nm1 are being pressed. As a result, the first assigner AS-1 and the second assigner AS-2 have the highest note nm1, the third assigner AS-3 has the second lowest n2, and the fourth assigner AS-4 has the lowest note n1. The tone generator 34 is selected to start sounding.
Then, the operation history storage unit 38 stores the time KON1 and information on the operation performed at that time, as shown in the first line of the operation history table of FIG.

At the next KON2 timing, the key of the pitch nm2 is pressed. Then, with the four pitch keys n1, n2, nm1, and nm2 being pressed, each assigner AS selects a pitch to be generated according to the rules shown in FIG. As a result, the first assigner AS-1 selects the highest tone nm2, and the second assigner AS-2, the third assigner AS-3, and the fourth assigner AS-4 select nm1, n2, and n1, respectively. . Accordingly, only the first assigner AS-1 whose pitch selection has been changed causes the musical tone generation unit 34 to start pronunciation of the selected pitch.
Further, the operation history storage unit 38 stores the time KON2 and information on the operation performed at that time, as shown in the second row of the operation history table in FIG.

  At the next timing of KOFF1, the second assigner AS-2 cancels the selection of the pitch nm1 in response to the release of the key of the pitch nm1, and the tone generator 34 stops the sound generation. Further, the operation history storage unit 38 stores the time KOFF1 and information on the operation performed at that time, as shown in the third row of the operation history table of FIG.

On the other hand, the key-off retrigger control unit 39 is within a predetermined time T2 from the key pressing operation of the key having the latest pitch nm2 to the key releasing operation of the key having the current pitch nm1, and the pitch at the time of the key releasing operation. Since the key of nm2 is being depressed, it is determined that the key release operation of the key of pitch nm1 is an operation related to the legato playing method. Then, it is determined to perform the key-off retrigger for the second assigner AS-2 that has selected the pitch nm2 until immediately before.
Then, in the operation of the key-off retrigger, the second assigner AS-2 selects a pitch that is pronounced according to the rules shown in FIG. 3 while the keys of the three pitches n1, n2, and nm2 are being pressed. . As a result, the second assigner AS-2 selects nm2 of the highest sound and causes the musical sound generation unit 34 to start the sound generation.

Further, the key-off retrigger control unit 39, as shown in the first line of the legato history table shown in FIG. 13, includes the legato performance determination result corresponding to the key release operation at the time KOFF1, and each key including the previous key press operation. Stores whether or not the pitch selection by the assigner has changed.
At this time, since the operation related to the legato playing method is detected only once, it does not correspond to the “predetermined condition”, and the late arrival priority setting unit 36 does not perform the setting using the late arrival priority.

At the next KON3 timing, the key with the pitch nm3 is pressed. Then, with the four pitch keys n1, n2, nm2, and nm3 being pressed, each assigner AS selects a pitch to be generated according to the rules shown in FIG. As a result, the first assigner AS-1 selects the highest sounding nm3, and the second assigner AS-2, the third assigner AS-3, and the fourth assigner AS-4 select nm2, n2, and n1, respectively. . Accordingly, only the first assigner AS-1 whose pitch selection has been changed causes the musical tone generation unit 34 to start pronunciation of the selected pitch.
Further, the operation history storage unit 38 stores the time KON3 and information on the operation performed at that time, as shown in the fourth line of the operation history table of FIG.

At the next timing of KOFF2, the second assigner AS-2 cancels the selection of the pitch nm2 in response to the release of the key of the pitch nm2, and the tone generator 34 stops the sound generation. Further, the operation history storage unit 38 stores the time KOFF2 and information on the operation performed at that time, as shown in the fifth line of the operation history table of FIG.
On the other hand, the key-off retrigger control unit 39 is within a predetermined time T2 from the key pressing operation of the key having the latest pitch nm3 to the key releasing operation of the key having the current pitch nm2, and the pitch at the time of the key releasing operation. Since the key of nm3 is being pressed, it is determined that the key release operation of the key of pitch nm2 is an operation related to the legato playing method. Then, it is determined to perform the key-off retrigger for the second assigner AS-2 that has selected the pitch nm2 until immediately before.

Then, in the operation of the key-off retrigger, the second assigner AS-2 selects a pitch to be generated according to the rules shown in FIG. 3 while the keys of the three pitches n1, n2, and nm3 are being pressed. . As a result, the second assigner AS-2 selects nm3 of the highest sound and causes the musical sound generation unit 34 to start the sound generation.
Further, the key-off retrigger control unit 39 stores various data in the legato history table shown in FIG.

  In addition, since the operation related to the legato playing method has continued twice, it corresponds to the “predetermined condition” for setting the late arrival priority. Therefore, the late arrival priority setting unit 36 refers to the legato history table, and the first assigner AS-1 and the second assigner AS-2 in which the selected pitch fluctuates due to the operations related to the two legato performances so far. Is set to use the late arrival priority rule.

  At the next KON4 timing, the key of pitch nm4 is pressed. Then, with the four pitch keys n1, n2, nm3, and nm4 being depressed, the third assigner AS-3 and the fourth assigner AS-4 generate pitches that are pronounced according to the rules shown in FIG. select. As a result, the third assigner AS-3 and the fourth assigner AS-4 select n2 and n1 as before. In addition, the first assigner AS-1 and the second assigner AS-2 select the pitch nm4 that is last pressed with priority on later arrival.

For this reason, the pitch selection is fluctuated in the first assigner AS-1 and the second assigner AS-2, and the tone generation unit 34 starts to generate the selected pitch.
Further, the operation history storage unit 38 stores the time KON4 and information on the operation performed at that time, as in the last row of the operation history table of FIG. FIG. 12 shows the state of the operation history table at this time.
Similarly, for the key pressing operation of the key N5 of KON5, which is the next key pressing operation, the pitch selection varies in the first assigner AS-1 and the second assigner AS-2, and the selected pitch is pronounced. Is started by the musical sound generator 34.

  Further, if the key release operation of the key with the pitch nm3 in KOFF3 and the key release operation of the key with the pitch of nm4 in KOFF4 are also the key release operations related to the legato performance, the operation related to the legato performance is 2 even at these timings. This is a “predetermined condition” for which the last arrival priority should be set. However, the first assigner AS-1 and the second assigner AS-2 whose selection pitches fluctuate due to the operation related to the legato playing method have already been set using the late arrival priority rule. The priority setting unit 36 does not perform any setting that uses the new arrival priority rule for any assigner AS. For the first assigner AS-1 and the second assigner AS-2, the condition for canceling the late arrival priority is not satisfied, and the late arrival priority remains.

As described above, in the electronic musical instrument 10, the functions of the late arrival priority setting unit 36, the operation history storage unit 38, and the key-off retrigger control unit 39 are used to press the presses having overlapping periods such as pitches nm 1 to nm 5 in FIG. When a key operation is performed and a plurality of assigners AS should select a pitch related to the key press, the plurality of assigners AS can simultaneously select a pitch related to the key press at the timing of the key press. .
Accordingly, as described with reference to FIG. 19, the timbre is not changed every time the key is pressed or the sounding start timing is not shifted for each part, and the adverse effect on the audibility is suppressed, and the performance operation of the performer is intended. Proper pronunciation can be performed easily.

  In addition, at the timing of KON2 and KON3, since the setting using the late arrival priority rule has not yet been made, the sounding start timing is slightly shifted between the tone color of the first assigner AS-1 and the tone color of the second assigner AS-2. Yes. At the timing of KON4 and KON5, this deviation is corrected by the setting using the late arrival priority rule.

  In the second embodiment, since it is directly determined whether or not the performance operation is related to the legato performance method, it is not essential to consider time in the “predetermined condition” used by the late arrival priority setting unit 36. Therefore, if a condition that does not take time into consideration is used, even when a performance with a legato performance is slow, this can be properly identified, and a setting using a late arrival priority rule can be made.

Next, processing executed by the CPU 11 in order to realize the functions performed by the CPU 11 among the functions shown in FIG. 11 will be described.
FIG. 15 is a flowchart of processing when key-on data and / or key-off data is received.
When the CPU 11 receives key-on data and / or key-off data from the detection circuit 16, the CPU 11 starts the processing shown in the flowchart of FIG. 15 by executing a required program. As described above, an operation performed with a timing difference within a predetermined threshold is regarded as a simultaneous operation.

  In the process of FIG. 15, the CPU 11 first stores the detected operation and its time in the operation history table shown in FIG. 12 (S61). Next, if the detected operation includes a key-on operation (Yes in S62), a sound assignment flag is set for all assigners AS so that the assigner AS can select a sound pitch according to the key-on operation (S63). ). If No in step S62, step S63 is skipped.

  Next, the CPU 11 determines whether or not the detected operation includes a key-off operation (S64). And if it is Yes here, the musical tone production | generation part 34 will be instruct | indicated to stop the sound generation of the pitch which concerns on the detected key-off operation (S65). When there are a plurality of key-off operations, an instruction to stop sound generation for all of them is given.

  Next, the CPU 11 determines whether or not the key that has been subjected to the key-on operation is still being operated within a predetermined time from the most recent key-on operation to the current key-off operation (S66). This is a determination as to whether or not the current key-off operation is an operation related to a legato performance, and is determined by referring to the operation history table of FIG. If Yes here, the CPU 11 sets a sound generation assignment flag for the assigner AS that has selected the pitch for which the key-off operation has been performed (S67). It can also be said that the sound generation assignment flag is set for the assigner AS corresponding to the part that has been generating the pitch N before stopping in step S65.

  The processes in steps S66 and S67 are processes related to the key-off retrigger function. When a plurality of key-off operations are detected, these processes are executed for each key-off operation. If No in step S66, step S67 is skipped and the process proceeds to step S68.

Next, the CPU 11 stores the detection results of the current key-off operation, the most recent key-on operation, and the legato performance operation (judgment result of step S66) in the legato history table shown in FIG. 13 (S68).
Thereafter, the CPU 11 executes the sound generation assignment process shown in FIG. 8 as in the case of the first embodiment. However, in the second embodiment, it is not necessary to execute the process of step S37. In this sound assignment process, for each assigner for which the sound assignment flag has been set in step S63 or S67, a sound production pitch is selected and a sound generation start process is performed as necessary.
In the case of No in step S64, steps S65 to S68 are skipped and the process proceeds to step S69.

  Next, the CPU 11 determines again whether or not the detected operation includes a key-off operation (S70). And if it is Yes here, the selection pitch fluctuation presence or absence of each assigner will be registered into the legato history table shown in FIG. 13 (S71). This registers whether or not there has been a change in the selected pitch of each assigner during the current key-off operation or the most recent key-on operation registered in step S68. Therefore, whether or not there is a change in accordance with the key-on operation is saved so that it can be referred to later when the processing of FIG. 15 is performed in accordance with the key-on operation. In step S71, the selection result in step S69 and its The presence / absence of variation may be stored with reference to the stored variation presence / absence.

  Thereafter, the CPU 11 determines, for each assigner, whether or not there has been a legato performance operation at a frequency equal to or more than a predetermined reference (S72). That is, it is determined whether or not the operation history stored in the legato history table (and the operation history table) satisfies a “predetermined condition” in which the selection rule of the pitch is to be given priority on the last arrival. If the answer is Yes, the late arrival priority flag is set to the assigner whose pitch selection fluctuates during the legato performance operation (S73), and the process ends.

It should be noted that when assigning an assigner in step S73, it may be based on the fact that all or a predetermined ratio or more of the legato performance operation in the range referred to in the determination in step S72 is changed. . For example, if it is determined in step S72 that “legato performance operation has been performed twice” as a reference, it is referred to whether or not the last two key-off operations are operations related to legato performance. In this case, the assigner whose pitch selection is changed may be specified.
If No in step S72, step S73 is skipped and the process is terminated.
In the case of No in step S70, steps S71 to S73 are skipped and the process is terminated.
With the above processing, the pronunciation as described with reference to FIG. 14 becomes possible.

In the second embodiment, it is preferable to use “the condition of step S72 was not satisfied when there was a key-off operation” as the release condition for releasing the late arrival priority flag. The flag cancellation processing using the cancellation condition may be performed in the case of No in step S72 in the processing of FIG. 15, or the processing of FIG. 9 is executed with a key-off operation as a trigger, and is performed according to the determination result in step S53. May be.
In addition to the condition of S72 described above, it is also preferable to use a temporal condition such as when a fixed time has elapsed since the last arrival priority was set last. The time condition may be determined by periodically starting the process of FIG.

[Comparative example of the second embodiment: FIGS. 16 and 17]
Next, the effect of using the late arrival priority will be described using the comparative examples of FIGS.
FIG. 16 shows that the same assigner as in the second embodiment is used, and that there is no late arrival priority setting unit 36 and key-off retrigger control unit 39. It is a figure which shows the example of pitch selection.

In this case, the pitch selection by each assigner AS is the same as in the case of FIG. 14 until the timing of KON2.
However, since the key-off retrigger is not performed at the timing of KOFF1, the second assigner AS-2 simply cancels the selection of the pitch nm1 and causes the tone generator 34 to stop the sound generation. Therefore, the pronunciation corresponding to the second assigner AS-2 is temporarily stopped here.

  At the timing of KON3, the second assigner AS-2 selects the pitch according to the rules shown in FIG. 3 while the four pitch keys n1, n2, nm2, and nm3 are being pressed. The third nm2 is selected from the above, and the tone generator 34 is caused to start sounding. However, this pronunciation is immediately stopped at the timing of KOFF2.

  Since the selection rule does not give priority to the last arrival, it is repeated that the pronunciation corresponding to the second assigner AS-2 starts immediately before the key release operation and stops immediately when the key is released. become. That is, from the performance operation, it is possible to infer the intention to continuously generate the sound from the pitch nm1 to the pitch nm5, but for the key depression after nm2, the sound substantially corresponding to the second assigner AS-2 Is not pronounced, resulting in a sound different from the pitch nm1, and it is considered that the pronunciation according to the intention of the performer cannot be performed.

FIG. 17 shows an example of pitch selection by each assigner AS when the same assigner as in the second embodiment is used and there is no late arrival priority setting unit 36 and the same key operation is performed as in FIG. FIG.
In this case, the pitch selection by each assigner AS is the same as in the case of FIG. 14 until the timing of KOFF2. Compared with the example of FIG. 16, since the key-off retrigger is performed, the sound corresponding to the first assigner AS-1 and the second assigner AS-2 can be generated for each key depression, and the performance is performed. The pronunciation is in line with the person's intention.

  However, after the timing of KON4, the pitch assignment rule of the second assigner AS-2 does not give priority to the last arrival, so the second assigner AS-2 performs the key-off retrigger at the timing of the key release operation of the previous key. To select the pitch of the key that was pressed next. For this reason, the sound corresponding to the first assigner AS-1 and the sound corresponding to the second assigner AS-2 are slightly deviated from the start and end timings of sound generation, which adversely affects hearing.

  On the other hand, by using the function of the late arrival priority setting unit 36, such a problem does not occur, and even if the key depression from the pitch nm1 to the pitch nm5 is partially overlapped by the legato playing method, the key depression is performed. As described above, it is possible to produce a sound without changing the timbre for each part and without shifting the sounding start timing for each part.

[Modification: FIG. 18]
This is the end of the description of the embodiment. However, the configuration of the apparatus, the configuration of the operator including the performance operator, the configuration of data used for processing, the specific processing procedure, etc. are described in the above embodiment. Of course, it is not limited to.

  For example, the timing at which the late arrival priority setting unit 36 determines whether to use late arrival priority based on a predetermined condition is not limited to that of the above-described embodiment. In the embodiment described above, this determination is performed at the timing when the key-on or key-off operation is performed. However, it is not hindered to perform the determination at a timing unrelated to these operations. Of course, the determination may always be made at the timing when some operation is performed regardless of the key-on operation or the key-off operation.

  In addition, the criterion for determining whether or not an operation in the second embodiment is a legato performance operation is not limited to that in the above-described embodiment. For example, there is an operation in the order of key-on of a certain pitch M, key-off of another pitch N that was operated before the key-on of pitch M, and the pitch M and pitch N at the time of pitch-M key-on. It is also possible to use a criterion that does not consider time, such as no key being pressed in between.

In the process of FIG. 15, since the late arrival priority flag is set later than the sound generation assignment process (S69), at the time of sounding at the timing of the key-off operation that triggered the late arrival priority flag, It was not possible to select the pitch with priority on the last arrival (unless the late arrival priority flag was already set).
There is no particular problem with this configuration. However, the following measures are conceivable when it is desired to select the pitch with priority on the last arrival even when the sound is generated at the timing of the key-off operation that is the trigger.

That is, at the time of step S69, the selection pitch by each assigner for performing the determination of step S72 is temporarily determined, and the setting of the late arrival priority flag according to the determination of step S72 is reflected again. It is conceivable to select the pitch that each assigner actually pronounces.
In this way, even if a key-on operation and a key-off operation are performed simultaneously, if the late arrival priority flag is set according to the key-off operation, it can be immediately reflected in the pronunciation according to the simultaneous key-on operation. The pitch selection rule can be switched more quickly.

  Further, in each of the above-described embodiments, an example in which the late arrival priority setting unit 36 and the key-off retrigger control unit 39 are provided separately from the assignment control unit 33 has been described. However, each assigner AS of the assignment control unit 33 has the late arrival priority setting unit 36 or The function of the key-off retrigger control unit 39 may be provided. In this case, as described with reference to FIGS. 7, 15, etc., each assigner AS determines whether or not it is necessary to use late arrival priority or key-off retrigger based on a predetermined condition. What is necessary is just to change a high selection rule to the last arrival priority, or to perform a key-off retrigger process.

  Also, the pitch selection rules set for each assigner may behave differently for each number of key presses, as shown in FIG. In FIG. 18, the rule is defined only for the number of key presses of 4 for the second assigner and the third assigner, but may be defined for the case of 5 or more.

  In the above-described embodiment, an example has been described in which the performance operator is a keyboard, and a sounding start instruction is performed by a key pressing operation and a sound generation stop instruction is performed by a key release operation. However, the form of the performance operator is not limited to this. The present invention can be applied not only to the shape of other musical instruments but also to an apparatus having a user interface having a shape completely different from that of a traditional musical instrument, such as a pad having operation units arranged in a matrix. In this case, the sound generation start instruction and the sound generation stop instruction are received by an operation method according to the characteristics of the user interface.

Further, it is not necessary for the electronic musical instrument 10 to incorporate a performance operator. It is also conceivable that performance data indicating the operation content of the performance operator is acquired from an external controller connected to the communication I / F 15 and the electronic musical instrument 10 grasps the operation state of each operation unit based on the performance data. .
It is also conceivable to use a GUI (graphical user interface) displayed on a keyboard of a general-purpose computer or a touch panel as a performance operator. In this case, it is possible to make the general-purpose computer function as an electronic musical instrument by realizing the functions of the respective units shown in FIG. In any case, the functions of the respective units shown in FIG. 2 and the like can be distributed and provided in a plurality of devices, and the functions of the electronic musical instrument 10 can be realized by cooperating them.

The program according to the embodiment of the present invention is a program for realizing the functions of the respective units (particularly the late arrival priority setting unit 36) shown in FIG. 2 and the like by causing one computer or a plurality of computers to cooperate. is there.
Then, by causing the computer to execute such a program, the above-described effects can be obtained.

  Such a program may be stored in a ROM or other nonvolatile storage medium (flash memory, EEPROM, etc.) provided in the computer from the beginning. However, it can also be provided by being recorded on an arbitrary nonvolatile recording medium such as a memory card, CD, DVD, or Blu-ray disc. Each procedure described above can be executed by installing the program recorded in the recording medium in a computer and executing the program.

Furthermore, it is also possible to download from an external device that is connected to a network and includes a recording medium that records the program, or an external device that stores the program in a storage unit, and install and execute the program on a computer.
Moreover, it is needless to say that the configurations of the embodiment and the modified examples described above can be arbitrarily combined and implemented as long as they do not contradict each other.

As is clear from the above description, according to the present invention, even when consecutive performance operations are partially overlapped, it is possible to easily generate a sound suitable for the intention of the player's performance operation while suppressing adverse effects on hearing. Can be done.
Therefore, the convenience of the electronic musical instrument can be improved by applying the present invention.
