[0003]

In the above-mentioned prior art, since only one sound can be assigned to one performance operator, it can be used only as a simple percussion instrument performance operator, and performance performance is limited. was there. On the other hand, the function of generating a plurality of tones by operating one key of the keyboard is known as a single finger function of automatic bass chord performance. However, in this case, the chord corresponding to the pressed key is fixed to the root note of the pressed key, and the chord cannot be freely assigned to the key. Therefore, it was necessary to accurately find and press the key of the desired chord when playing. Moreover, such a function is usually exerted in combination with the automatic rhythm progression, and it was not possible to produce a sound at a free timing as the player's will.

[0007]

According to the first aspect, by the assigning means,
In the assignment mode, an arbitrary plurality of sounds can be assigned corresponding to one performance operator, and in that case, any musical sound designated to be assigned when the performance operator is in the operating state is assigned to the operator. At the same time, the assignment can be changed by changing the musical sound instructing the assignment, and the assignment is fixed when the operator changes from the operating state to the non-operating state. Therefore, it is possible to perform an operation for allocating a plurality of arbitrary sounds to one performance operator with a margin, and there is an advantage that the operation of allocating a plurality of sounds is very easy. The plurality of sounds assigned to the performance operator are
When the performance operator is operated, the musical tone signal generating means simultaneously produces sound. Therefore, if desired plural tones are assigned to the performance operator in accordance with the musical composition to be played at each performance opportunity, when the plural tones are to be generated, the performance operator is operated only once. With this, it is possible to easily generate the desired plural sounds at the same time. By doing so, it is possible to easily perform a multi-tone simultaneous performance such as a chord.

According to a second aspect, a plurality of performance operators, a first mode in which a plurality of sounds are simultaneously generated corresponding to an operation of one performance operator, and an operation of one performance operator are provided. Correspondingly, a mode selecting means capable of selecting a second mode in which a plurality of tones are sequentially generated is provided. Therefore, when a certain performance operator is arbitrarily assigned according to the first mode, the performance is selected. You can easily play multiple notes simultaneously, such as the above chord, by operating the control once.
On the other hand, when a performance operator is arbitrarily assigned according to the second mode, the sequence tone can be easily played by operating the performance operator only once. In this way, performances in two different modes can be mixed, and performance performance is greatly improved.

According to a third aspect, information indicating a setting state of at least one operator among various setting operators for tone control or effect setting corresponds to allocation of a plurality of sounds to the performance operator. Then, it is stored in the storage means. Then, in response to the operation of the performance operator, a tone signal corresponding to a plurality of tones assigned to the performance operator is simultaneously pronounced, and the setting information stored in the storage means is read out. Is performed on the tone signal. As a result, when assigning a sound to a performance operator, it is possible to assign any setting state of various setting operators corresponding to this performance operator. Therefore, when the performance operators are operated to reproduce and reproduce the plurality of assigned sounds at the same time, desired setting states of various setting operators can be reproduced at once, so that control of reproduced sounds and reproduction of the reproduced sounds can be performed. Various effects to be added to the sound can be reproduced in a desired setting state, the operation is easy and the reproducibility is excellent, and the performance effect can be further improved. Further, when a plurality of performance operators are provided, different setting states can be assigned to the respective performance operators, so that the performance can be improved in this respect as well. For example, when a plurality of performance operators are simultaneously operated to generate assigned sounds, musical tones can be controlled or effects can be given in different setting states for each sound corresponding to each performance operator. No playing effect is obtained.

According to the fourth aspect, arbitrary plural tones are sequentially assigned in correspondence with the performance operator in an arbitrary sounding order, and at least one of the setting operator means is associated with this assignment. Information indicating the setting state of the operator is stored together with the time change of the setting state. When the performance operator is operated, a plurality of sounds assigned to the performance operator are sequentially generated, and the change in the setting state is reproduced over time based on the memory of the storage means. , Tone control or effect imparting control according to the reproduced setting state. As a result, not only can sequenced sounds be played easily, but the setting states for various musical tone controls or effect addition controls can also be changed automatically in a sequential manner. In addition to being obtained, it has an excellent effect that it is easy to operate.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram of a hardware structure showing an embodiment of an electronic musical instrument according to the present invention. Various processes are executed below. A keyboard circuit 14, a panel switch circuit 15, and other various circuits are connected to the microcomputer via a data and address bus 13. The keyboard circuit 14 is
This circuit is provided corresponding to a keyboard having a plurality of keys for designating the pitch of a musical sound to be generated, and includes a key switch corresponding to each key of the keyboard. The panel switch circuit 15 is a circuit including a switch group corresponding to various operators for selecting, setting, and controlling tone color, volume, pitch, effect, and the like. An indicator 16 including an LED or the like is provided corresponding to a predetermined switch in the panel switch circuit 15 so that the ON / OFF state of the function corresponding to each switch can be displayed.

A plurality of performance operators (for example, 5
Individual pads P0 to P4 are provided. Each pad P0
A sensor is provided at P4, detects that the pad has been operated by a player's hand or the like, and provides the bus 13 with ON / OFF information of the pad. These pads P0-P
The arrangement of 4 is preferably a position where the player can easily operate. For example, it may be near the keyboard or at an appropriate position on the front panel, and the pads P0 to P4 are separated from the electronic musical instrument body as a separate unit so that they can be freely placed in a position where the player can easily operate. May be. Arbitrary plural sounds can be assigned to each of the pads P0 to P4, and this assignment processing is performed by the pads and the panel switch circuit 15
It is performed under the control of the CPU 10 based on the operation of a predetermined switch or the like. For convenience, this assignment process will be referred to as a pad assignment process.

The tone signal generation circuit 17 is capable of generating different tone signals for a plurality of tone generation channels (16 channels as an example). The tone assigning process for each tone generating channel (this is known as the key assigning process) is performed by the CP.
It is performed under the control of U10. Information indicating a musical tone assigned to each musical tone generating channel is given to the musical tone signal generating circuit 17 via the bus 13, and the musical tone signal generating circuit 17 generates a musical tone signal in each musical tone generating channel based on this information. As is well known, the tone generation channels in the tone signal generation circuit 17 may be formed in a time-sharing manner by using a common hardware circuit for each channel in a time-sharing manner, or separate hardware. It may be formed in parallel by a wear circuit.

Any tone signal generation method may be used in the tone signal generation circuit 17. For example, a method of sequentially reading tone waveform sample value data stored in a waveform memory according to address data that changes according to the pitch of a tone to be generated (memory reading method), or the address data as phase angle parameter data. A method for obtaining musical tone waveform sample value data by performing a predetermined frequency modulation operation (FM method) or a method for performing a predetermined amplitude modulation operation using the above address data as phase angle parameter data to obtain musical tone waveform sample value data ( Any known method such as AM method) may be used. Further, when the memory reading method is adopted, the musical tone waveform stored in the waveform memory may be only one period waveform, but it is preferable to use a plurality of period waveforms because the sound quality can be improved. A method of storing a plurality of periodic waveforms in a waveform memory and reading the waveforms is, for example, as shown in Japanese Patent Laid-Open No. 52-121313, a method of storing all waveforms from the start to the end of sound generation and reading the waveforms once or 58-142
No. 396, a method of storing a plurality of periodic waveforms of an attack portion and one or a plurality of periodic waveforms of a sustain portion, reading the waveform of the attack portion once and then repeatedly reading the waveform of the continuous portion, or Various methods are known, such as a method of storing a plurality of discretely sampled waveforms as shown in No. 60-147793, sequentially switching and specifying the waveforms to be read, and repeatedly reading the specified waveforms. Therefore, these may be appropriately adopted.

The tone signal generating circuit 17 may of course be provided with not only the tone generating channels for generating the scale tones but also various devices such as a rhythm sound source and an automatic performance function. The digital tone signal generated from the tone signal generation circuit 17 is converted into an analog tone signal by the digital / analog converter 18, and is spatially generated via the sound system 19. Timer 2
0 generates a clock pulse of a predetermined cycle, and the timer clock pulse is added to the CPU 10 and acts as a timer interrupt signal.

In the embodiment, the tone generation mode (hereinafter referred to as a pad mode) corresponding to the operation of the pad has two modes: a simultaneous tone generation mode and a sequence tone generation mode. First, the "simultaneous sound generation mode", which is the first mode, is a mode in which a plurality of tones are simultaneously sounded in response to the operation of one pad. The second mode, "sequence sound generation mode", is a mode in which a plurality of tones are sequentially generated in response to the operation of one pad. Some mode selecting means is provided for selecting the pad mode. In the above-mentioned pad assigning process, which pad mode is to be used for sounding a desired pad is selected (mode selection), and the assigning process according to the selected mode is performed. At this time, the sounding time intervals of the sequence sounds in the "sequence sounding mode" can be set arbitrarily at the time of allocation. For example, a method is appropriately adopted in which the sounds to be sequentially pronounced are selected or designated at desired time intervals, and the time interval information is stored together with the information of the selected sounds.

In order to assign an arbitrary plurality of tones to a desired pad, some sort of selection means for selecting a tone to be assigned is provided. As an example, selection of an arbitrary note to be assigned to a pad can be performed by a key pressing operation on the keyboard, and a plurality of scale notes can be assigned to the pad. Appropriate storage means are provided for storing the information of the sound assigned to each pad according to the selection by the selection means. An appropriate area in the data and working RAM 12 (this is called a pad memory) is used as this storage means.

2A, 2B and 2C show an example of the format of the pad memory in the data and working RAM 12. First, areas of the pad memories PDM0 to PDM4 are prepared for the respective pads P0 to P4 (see a in FIG. 2). Each pad memory PDM0 to PDM4
The storage format inside the pad depends on the pad mode currently selected for each pad. FIG. 2B illustrates a storage format in one pad memory PDM in the simultaneous tone generation mode. FIG. 2C illustrates a storage format in one pad memory PDM in the sequence tone generation mode.

The stored data in the simultaneous tone generation mode will be described with reference to FIG. 2B as follows. PM (PN): Pad mode data: PN is a pad number, and the pad (P
0 to P4). This is data indicating what pad mode is currently selected (assigned) to the pad corresponding to this pad number. It is "0" in the simultaneous tone generation mode and "1" in the sequence tone generation mode. PTC (PN): Pad tone data: This pad number P
This is data indicating what timbre is currently assigned to the pad corresponding to N. This data consists of code data indicating a tone color. Therefore, it is possible to assign a different tone color to each pad.

P (PN): Pointer: This is not used in the simultaneous tone generation mode and will be described later. PAT (PN): Pad assigned sound data: data of a plurality of sounds assigned to the pad corresponding to the pad number PN by the pad assigning process, one for each sound
Use the byte area. In this example, 5 bytes can be simultaneously pronounced at the maximum, so 5 bytes are used for storing the pad-assigned sound data. It should be noted that the breakdown of the 1-byte data forming the data for one note is a multi-bit key code indicating the pitch (key) of the assigned note,
It is composed of a 1-bit flag for indicating that it is allocated. TGCHF: Sound source channel flag: This is a flag that indicates to which tone generation channel each tone indicated by the above-mentioned assigned tone data is assigned for sound generation. In the pad assigning process, it does not specify which musical tone generation channel the assigned notes are to be played. The assignment to the tone generation channel is performed by the key assignment process. The sound source channel flag stores which channel is assigned by the key assign process.
This sound source channel flag consists of 2 bytes = 16 bits, 1 bit corresponds to 1 channel, and “1” is set to the bit corresponding to the channel to which the pad-assigned sound is assigned.

The stored data in the sequence tone generation mode will be described with reference to FIG. 2C as follows. PM (PN): Pad mode data: As described above. PTC (PN): Pad tone color data: As described above. P (PN): Pointer: A pointer for designating the event order, which will be described later, in order to control the sequence sounds to be emitted in order. Sequence data area: An area for storing the sequence sound data assigned to the pad corresponding to the pad number PN by the pad assignment process in the order of events (sounding timing order). , 20 events = 40 bytes in total. The 2-byte data for one event consists of event data E (PN, p) and duration data D (PN, p). p = 0, 1, 2, ...
, 19 are event rankings, and the pointer P (P
N). Event data E (PN, p)
Consists of a 1-bit event flag and a multi-bit key code indicating the pitch (key) of the assigned sound related to the event. The event flag is "1" for a key-on event and "0" for a key-off event. The duration data D (PN, p) is data indicating the time interval from the event to the next event. In addition,
A predetermined end mark code is stored at the end of the sequence. TGCHF: Sound source channel flag: As described above.

Next, an example of the processing executed by the microcomputer will be described with reference to the flowcharts of FIGS. FIG. 3 shows an example of the main routine. First, after performing a predetermined initialization process, "key process", "pad process", "panel switch process",
The "other processing" routine is repeated. In the "key processing", each key switch in the keyboard circuit 14 is scanned to detect the ON / OFF of the key switch. When a key-on event, the key-on event processing shown in FIG. A key-off event process is performed as an example. In the "pad processing", the sensors of the pads P0 to P4 are scanned to detect the ON / OFF of the sensors, and the pad-on event processing shown in FIG. 6 is performed at the pad-on event, and the pad-off event is performed. Pad-off event processing, an example of which is shown in FIG. 7, is performed. In the "panel switch processing", various operators and switches in the panel switch circuit 15 are scanned to detect ON / OFF, and various processing is performed based on the detection. An example of processing executed in this "panel switch processing" is shown in FIG.
This is shown in FIGS. In "other processing", various other processings are performed. One of the processes performed here is a sequence control process as shown in FIG.

During execution of the main routine, interrupts are periodically applied by the clock pulse of the timer 20. In that case, the timer interrupt process of FIG. 12 is performed. Here, the content of the timer register TIME is incremented by 1. Therefore, the timer TIME is free running and its overflow is ignored. In the initial setting process, each pad memory PDM0 to PDM
4 may be preset with predetermined initial data. Then, when the power is turned on, a predetermined plurality of sounds can be initially assigned to the pads P0 to P4.
Of course, such initial allocation may not be performed.

--Selection of Pad Mode-- The pad mode can be selected by operating the pad assign switch PASW in the panel switch circuit 15 during the pad assign process. For more information,
In this embodiment, the pad assign switch PAS
The pad assign mode is determined according to the operation of W, and the pad mode is determined according to the pad assign mode. The pad assign mode will be described. There are four modes, 0 to 3. The four pad assign modes are instructed as follows by the contents of the register PAM.

PAM = 0: Play mode: Indicates a mode in which normal performance is performed, that is, the pad assignment process is not performed. PAM = 1: Plural note assigning mode: A mode for assigning arbitrary plural notes to be sounded simultaneously to one desired pad. When this mode is selected, the simultaneous tone generation mode is selected as the pad mode. In the embodiment, this mode is selected by operating the pad assign switch PASW before operating the desired pad. PAM = 2: Sequence sound assignment preparation mode: A mode showing a first state (preparation state) when allocating arbitrary plural notes to be sequentially pronounced corresponding to one desired pad. When this mode is selected, the sequence tone generation mode is selected as the pad mode. In the example,
This mode is selected by operating the pad assign switch PASW while operating the desired pad. PAM = 3: Sequence sound allocation storage mode: A mode indicating that the storage operation is started when the sequence sound is allocated. In the embodiment, the sequence sound allocation preparation mode (P
When the assigned sound is selected by pressing a desired key when AM = 2), the mode is switched to this mode.

When the pad assign switch PASW is operated, the pad assign switch ON event process shown in FIG. 8 is executed. First, in step 30, the contents of the pad assign mode PAM are checked. If PAM = 0, go to step 31 and select one of the pad switches P
Check whether 0 to P4 are turned on at the same time. If the answer is NO, it means that the pad assign switch PASW is pushed before the pad switches P0 to P4, and the process goes to step 32 to set the pad assign mode PAM to 1. In this way, the plural sound allocation mode is selected. If YES at step 31, the process goes to step 33 to set the pad number of the pad which is already turned on in the register i. Next, in step 34, the pad assign mode PAM is set to 2. In this way, the sequence sound allocation preparation mode is selected. By operating the pad assign switch PASW again,
The pad assign process can be ended, but this point will be described later. As shown in FIG. 13, a display device such as an LED is provided beside the pad assign switch PASW so as to display according to the state of the pad assign mode PAM. For example, by controlling to turn off the light when PAM = 0 and turn on the light when PAM ≠ 0, it is possible to display that the pad assigning process is being performed.

--- Assignment of Plural Tones --- If PAM = 1 is set as described above, the plural tone allocation mode is selected. In this state, a desired pad (one of P0 to P4) desired to be assigned is turned on. Then, the pad-on-event process of FIG. 6 is started, and the following process is performed to produce the sound currently assigned to the pad. First, the pad number of the turned-on pad is stored in the register PN (step 35). Next, the pad assign mode PAM is 2 or 3
Is checked (step 36). No, because PAM = 1 now, go to step 37 and register P
Store the pad number of N in register i. Next, the pad memory PDM corresponding to the pad number of the register PN
The pad mode data PM (PN) is read from (one of PDM0 to PDM4) and it is checked whether it is "0" (step 38). If it is "0", the simultaneous tone generation mode is set, and by the processing of steps 39 and 40, the pad assigned sound data PAT is written from the pad memory PDM.
(PN) is read out, a plurality of tones corresponding to the pad assigned tone data are assigned to different channels, and the tone signal generating circuit 17 generates these tones. On the other hand, if it is not "0", it is the sequence tone generation mode, and the event data and duration data of each sequence sound are sequentially read from the sequence data area of the pad memory PDM by the processing of steps 41 to 47 and FIG. Are respectively assigned to appropriate channels, and these sounds are generated by the tone signal generation circuit 17. The details of the sound generation control in the simultaneous sound generation mode and the sequence sound generation mode will be described later.

In this way, the operator can confirm the sound already assigned to the pad by ear. Then, while the ON operation of the pad is being continued, the desired key to be newly assigned is pressed. Then, the key-on event process of FIG. 4 starts and the following process is performed. First, the key code of the newly pressed key is registered in the register KCD (step 48). Next, it is checked whether the tone color code TC of the currently selected tone color is the value "&HFF" indicating keyboard percussion (step 49). Note that keyboard percussion means that a key on the keyboard is used as a percussion instrument sound designating operator, in which case the tone color code TC is set to a predetermined value "&HFF",
A tone color name, that is, a percussion instrument tone name is designated by a key code.

If the pressed key is a normal scale-designated key, the process proceeds to step 50, where a normal sounding process (including a key assigning process for assigning sound to any one of 16 channels) is performed, and the pitch of the pressed key is increased. Generate a tone signal with. If the pressed key is the designated key for the keyboard percussion, the process goes to step 51 to perform a predetermined sounding process for the keyboard percussion. In the next step 52, the tone generator channel flag TGCHF of the channel in all the pad memories PDM0 to PDM4 for the channel used in the tone generation processing is turned off. This is because when the channel has already been used by the pad, the use is canceled and the latest key press, which is the latest event, is given priority. Next step 5
In 3, check the contents of the pad assign mode PAM,
If AM = 0 or 1, this process ends.

In this way, when one or more desired keys to be assigned to the pad are pressed, the above process is performed for each pressed key. If you do not want to assign the key once pressed to the pad, you can release the key. Finally, with one or more desired keys pressed, the pad that has been kept on until then is turned off. Then, the pad-off event process of FIG. 7 is started, and the following process is performed, and the musical tones corresponding to one to a plurality of keys being pressed are assigned to the pad. First, the pad number of the turned off pad is stored in the register PN (step 54). next,
Pad memory PD corresponding to the pad number of register PN
M (one of PDM0 to PDM4, PDM (PDM
Pad mode data PM (PN) is read from (denoted as N)) and it is checked whether PM (PN) = "0" (step 55). If YES, the process proceeds to step 550, the pad tone color data PTC (PN) is read from the pad memory PDM (PN), and PTC (PN) ≠ & HFF.
To find out. If YES, the process proceeds to step 56, and the tone signal generating circuit 17 (indicated by TG in the flow chart) corresponds to the channel (indicated by CH in the flow chart) in which the tone generator channel flag TGCHF in the pad memory PDM (PN) is ON. ) To a key-off signal. This is because the assigned sound of the pad up to that point is being sounded, so that the sounding assignment is canceled. In step 57, all tone generator channel flags TGCHF in the pad memory PDM (PN) related to the off pad are turned off.

Even if PM (PN) = "0", that is, in the simultaneous tone generation mode, if the keyboard percussion sound is generated, step 550 is NO, and step 56 is skipped and step 57 is executed. In the case of keyboard percussion sounds, without giving a special key-off signal,
This is because the sound is muted. If the assigned sound up to that point is a sequence sound, PM
Since (PN) = "1" and step 55 is NO, the process goes to step 58 without performing steps 56 and 57. This is because, in the case of the sequence sound, the mute processing is performed by the event data.

In the next step 58, PAM = 1 and P
Check if N = i. In the present example, since the mode is the multi-tone assign mode, the pad assign mode PAM =
It is 1. The register i stores the pad number related to the latest pad-on event (step 37 in FIG. 6), and the register PN stores the pad number related to the current pad-off event. Usually PN
= I, step 58 becomes YES, and step 5
Go to 9. In step 59, the presence or absence of the currently pressed key is checked. If there is a pressed key, step 60-
At 62, allocation data is written to the pad memory PDM (one of PDM0 to PDM4) corresponding to the pad number designated by the register i. That is, the pad memory P corresponding to the pad number i
The pad mode data PM (i) in DM is set to "0", and it is stored that the simultaneous tone generation mode is selected corresponding to this pad (step 60). Then, the tone color code TC indicating the tone color currently selected is stored as the pad tone color data PTC (i) in the pad memory PDM corresponding to the pad number i (step 60). Further, the key code of the currently pressed key is written as the pad assigned sound data PAT (PN) in the pad memory PDM corresponding to the pad number i (step 6).
1). In this case, the key code of up to 5 tones can be written, and when the number of simultaneous keys is 6 or more, only 5 keys are selected according to a predetermined priority selection criterion, and the key code is written. The priority selection criterion may be determined as appropriate, such as high tone priority, low tone priority, or priority at a new key depression time. Further, an on-flag “1” indicating allocation is set in correspondence with the written key code. When the number of keys pressed simultaneously is less than 5, the data "&H0" indicating no key code is displayed in the remaining area where the key code is not stored.
0 "and the off flag" 0 "are stored (step 62).

As described above, when one or more desired keys to be assigned to the ON-operated pad are pressed and the pad which has been continuously ON-operated until then is turned OFF, the corresponding one or more keys are dealt with. The sound information is stored in the pad memory PDM corresponding to the pad. In this way, desired one or more tones are assigned to the pad. If you do not intend to change the assigned sound after turning on a pad to play the sound assigned to it and confirming it, perform a key depression operation to select a new assigned sound. Without turning off the pad. In that case, since step 59 becomes NO, steps 60 to 62 are executed.
The process ends without performing the process. If a certain first pad is turned on, another second pad is turned on before turning it off, and then the first pad is turned off, PN = i in step 58 is satisfied. No, step 60
The processing of ~ 62 is not performed. When the second pad is turned off, PN = i in step 58 is established, and step 60-
The process of 62 is performed.

The tone color of the assigned sound can be freely selected. In this embodiment, when assigning a scale note to a pad, the assignable tone color is 1 per pad.
There are only types. In that case, the desired tone color to be assigned in the panel switch circuit 15 is selected in advance. When the tone color switch of the desired tone color is turned on, the tone color switch on event process of FIG. 10 is performed, and the tone color code TC corresponding to the turned on tone color switch is registered as information of the selected tone color. By storing this tone color code TC as the pad tone color data PTC (i) in step 60 of FIG. 7, a desired tone color is assigned.
In this case, the tone color information regarding a plurality of tones assigned to one pad is common, but it goes without saying that a different tone color may be assigned to each tone as a modification example.

It is also possible to assign keyboard percussion sounds to the pads. For that purpose, the keyboard percussion mode is set in advance. The keyboard percussion mode is a keyboard percussion switch KPSW provided in the panel switch circuit 15.
It is turned on / off according to the operation of. When the keyboard percussion switch KPSW is turned on, the keyboard percussion switch on event processing of FIG. 9 is performed. First, it is checked whether the tone color code TC has a predetermined value "&HFF" indicating the keyboard percussion mode (step 63). If it is not in the keyboard percussion mode, branch to NO, save the tone color code TC at that time in the buffer TCBUF (step 64), and then change the tone color code TC to the code "&HFF" indicating the keyboard percussion mode. (Step 65). After changing to the keyboard percussion mode in this way, the desired pad is turned on and the key corresponding to the desired keyboard percussion sound is pressed. Then, as described above, when the pad is turned off, the key code of the pressed key is stored in the pad memory PDM together with the tone color code TC indicating the keyboard percussion mode. To stop the keyboard percussion mode, turn on the keyboard percussion switch KPSW again. Then, step 63 branches to YES, and the tone color code stored in the buffer TCBUF is re-registered as the tone color code TC (step 66).
As shown in FIG. 13, a display device such as an LED is provided beside the keyboard percussion switch KPSW so that a display corresponding to the state of the keyboard percussion switch mode is performed. For example, when the keyboard percussion mode is selected (TC = &
Lights up when HFF) and when not selected (TC ≠ &
It is controlled to turn off the light (in the case of HFF). To end the multiple tone assignment mode, press the pad assign switch P
Turn on the ASW again. Then, in step 30 of FIG. 8, it is determined that PAM = 1 (plural note allocation mode), the process proceeds to step 67, and the content of the pad assign mode PAM is reset to PAM = 0 (play mode).

--- Assignment of Sequence Sound ---- If the sequence sound is to be allocated as described above, first, the desired pad (one of P0 to P4)
Turn on first. Then, the pad-on-event process of FIG. 6 is started. At this time, since PAM = 2 or 3 is not satisfied, step 36 is branched to NO and the same process as described above is performed, and the sound currently assigned to the pad is reproduced. Is pronounced. If you want to assign a new sequence sound to this pad after confirming the already assigned sounds by this,
Turn on the pad assign switch PASW. Then, step 31 of FIG. 8 branches to YES, the pad number of the pad that is turned on is stored in the register i, and P
AM = 2 is set to enter the sequence tone allocation preparation mode. The pad may be turned off at any time after setting PAM = 2. The sequence sound is assigned / stored at each key depression / key release event, not at the pad off timing.

After setting PAM = 2, the operator sequentially presses desired plural keys designating plural sounds to be assigned as sequence sounds at desired timing. in this case,
It does not matter if two or more keys are pressed twice in a certain period. In response to this series of key operations, the key-on event process of FIG. 4 is performed when the key is pressed, and the key-off event process of FIG. 5 is performed when the key is released. Then, for each event, as described below, the pad memory PD
The sequence data is stored in M, and sequence sounds are assigned. When the key is pressed, the key code of the pressed key is registered in the register KCD and the musical sound is generated by the processing of steps 48 to 52 in FIG. When the first key is pressed, it is still PAM = 2, so in step 53 it is determined that PAM = 2, and the routine proceeds to step 68. In step 68, the pad assign mode is set to PAM = 3 to set the sequence tone allocation storage mode. Next, the pad memory PDM corresponding to the pad number of the register i (one of PDM0 to PDM4 is 1
Pad mode data PM (i) is set to "1", and it is stored that the sequence tone generation mode is selected corresponding to this pad (step 69). Then, the tone color code TC indicating the tone color currently selected is stored as the pad tone color data PTC (i) in the pad memory PDM corresponding to the pad number i (step 6).
9).

Next, the predetermined one-measure time length data MJL is added to the current value of the timer TIME, and the result is stored in the sequence end time register ENDT (step 70). This is, for example, to limit one phrase of the sequence sound to a time corresponding to one bar.
Next, the pointer P (i) in the pad memory PDM corresponding to the pad number i of the pad to be assigned is set to the initial value 0 (step 71). Next, in the sequence data area (see c in FIG. 2) in the pad memory PDM corresponding to the pad number i, the pointer P
(I) First event data E specified by = 0
The key code of the register KCD (that is, the key code of the key just pressed) and the on-event flag "1" are stored as (i, 0) (step 72). And
The current value of the timer TIME is set to the old time register OL
The event occurrence time of this time is stored by setting it in DT (step 73).

When the second and subsequent keys are pressed, PAM = 3 has already been set, so in step 53, PA is set.
It is determined that M = 3, and the process proceeds to step 74. In step 74, the value of the old time register OLDT is subtracted from the current value of the timer TIME to obtain the difference between the previous event occurrence time and the current event occurrence time, that is, the event time interval, and store it in the duration register D. next,
In the sequence data area (see c in FIG. 2) in the pad memory PDM corresponding to the pad number i, the duration register is designated as the duration data D (i, P (i)) of the event order designated by the pointer P (i). The time interval data stored in D is stored (step 75). For example, if P (i) = 0, the time interval data of the duration register D is stored as the duration data D (i, 0) of the first event ranking. Next, the pointer P (i) is incremented by 1 and the next event ranking (that is, the ranking of the current event) is designated (step 76).

In the next step 77, the event data E (i, P) of the event order designated by the pointer P (i) in the sequence data area (see c in FIG. 2) in the pad memory PDM corresponding to the pad number i.
As (i)), the key code of the register KCD (that is, the key code of the key related to the current on event) and the on event flag “1” are stored. In the next step 78,
It is checked whether the value of the pointer P (i) has reached the maximum value of 19.
If NO, go to step 79 and set the current value of the timer TIME in the old time register OLDT. In this way, the duration data D related to the previous event ranking corresponding to the new key-on event
(I, P (i)) and event data E (i, P (i) +1) related to the current event ranking are written.

When the pressed key is released, the key-off event process of FIG. 5 starts. First, the key code of the key released this time is registered in the register KCD (step 80). Next, the tone color code TC of the currently selected tone color is the value "&HF" indicating the keyboard percussion.
It is checked whether or not it is F "(step 81). If the released key is a normal scale-designated key, step 81 returns N.
Since it is O, the routine proceeds to step 82, where normal muffling processing is performed. For example, as is well known, a key-off signal is transmitted corresponding to the channel to which the released key is assigned,
The volume envelope of the channel is switched to the attenuation mode to attenuate the pronunciation of the tone signal related to the key release. In the next step 83, the pad assign mode is PAM =
Check 3 In the case of the present example, since PAM = 3 has already been set, the determination result is YES and the process proceeds to step 84.

The processing of steps 84 to 89 is almost the same as the processing of steps 74 to 79 in FIG. The difference is that in step 87, as event data E (i, P (i)) of the event order designated by the pointer P (i),
It is only that the key code of the register KCD (that is, the key code of the key related to the off event this time) and the off event flag “0” are stored. In this way, even when the key-off event is dealt with, similarly, the duration data D (i, P (i)) relating to the previous event ranking and the event data E (i, P (i) + relating to the current event ranking.
1) and are written. If the released key is the keyboard percussion designated key, step 81 is YES, and the key off event process is terminated without performing the subsequent process. This is because the percussion sound is attenuated irrespective of the key release operation, and no special silencing processing is required.

When the value of the pointer P (i) becomes the maximum value 19 due to the increment in step 86, step 88 becomes YES and the routine proceeds to step 90. Here, the pad assign mode is set to PAM = 0, that is, the play mode (step 90), and a predetermined end mark code is written at the position of the duration data D (i, 19) of the event ranking 19 (step 91). Then, the value of the pointer P (i) is set to "&HFF". This completes the pad assign process. The same applies when the value of the pointer P (i) reaches the maximum value 19 during the key-on event process, and step 78 in FIG.
Then, the process in steps 93 to 95 is performed, which is exactly the same as steps 90 to 92, and the pad assigning process is terminated.

On the other hand, as shown in FIG.
1 sequence control processing is performed. Here, first,
Pad assign mode is checked (step 9)
6). As described above, when the sequence tone allocation storage mode is being executed, PAM = 3, and the routine proceeds to step 97, where it is determined whether the current value of the timer TIME matches the value of the sequence end time register ENDT or exceeds it. Find out. If NO, this routine is ended, but if YES, steps 98 to 100 are executed. The processing of steps 98 to 100 is exactly the same as the processing of steps 90 to 92 in FIG. 5 described above, and thus the sequence sound allocation processing ends. The sequence sound allocation process can also be ended by turning on the pad assign switch PASW again during execution of the sequence sound allocation storage mode. In that case, it is determined that PAM = 3 in step 30 of FIG. 8, and the processes of steps 101 to 103 are executed. The processing of steps 101 to 103 is the same as step 90 of FIG.
The process is exactly the same as 92. If another pad is turned on while the sequence sound is being assigned to a certain pad, the pad assign mode PAM
Is 2 or 3, therefore, in the key-on event processing of FIG. 6 executed when the other pad is turned on,
If step 36 becomes YES, the key-on event process is not performed and the process returns to the main routine.

--Simultaneous Sound Generation of Plural Tones-- By turning on a desired pad, plural tones assigned to the pad can be sounded. When the pad is turned on, the pad-on event process of FIG. 6 starts, as described above, and the pad memory P corresponding to the pad is started.
The pad mode data PM (PN) is read from DM (PN) and it is checked whether it is "0" (step 38). If the pad mode selected corresponding to the pad is the simultaneous tone generation mode, PM (PN) = “0”,
The processing of steps 39 and 40 is performed. In step 39,
The pad memory PDM (P
The key code assigned to the pad is read from the area of the pad assigned sound data PAT (PN) of N) and assigned to different channels. The key code and the key-on signal are sent to the tone signal generating circuit 17 in correspondence with these key codes assigned to the channels. In addition, the pad tone color data PTC (PN) from the pad memory PDM (PN).
Is read out, and this is also sent to the tone signal generation circuit 17. In the corresponding channel of the tone signal generating circuit 17, tone signals corresponding to these one to a plurality of key codes are formed and generated with tone colors corresponding to tone color data.

In this way, one or more tones assigned to the pad which has been turned on are simultaneously produced by one pad operation. For example, if a desired chord is assigned to the pad, the chord performance can be easily performed by operating the pad once. Moreover, since the content of the pad assignment can be changed appropriately according to the performance purpose, a limited number of pads can be efficiently used as performance operators for various chords or arbitrary multiple notes. Easy to operate. In step 40, the pad memory P corresponding to the channel determined in the previous step is assigned.
Sound source channel flag TGCHF in DM (PN)
Is set to "1".

When the pad which has been turned on is turned off, the pad off event process of FIG. 7 is started as described above, and the pad mode data PM (PN) and the pad tone color data PTC of the pad relating to the off event of this time are started. (PN)
However, PM (PN) = "0" and PTC (PN) ≠ & HF
It is checked whether it is F (steps 55 and 550). If it is the simultaneous tone generation mode and the normal tone color, the process goes to step 56, and a key-off signal is sent to the channel to which one or more tones assigned to the pad are assigned to be emitted (channel in which the tone generator channel flag TGCHF is on). To do. As a result, the sound generated by the channel is set to the attenuated sound generation state after the key is released, and one or a plurality of sounds corresponding to the pad are muted. After that, the routine proceeds to step 57, where all the tone generator channel flags TGCHF in the pad memory PDM (PN) related to the off pad are turned off. If the tone assigned to the pad is a keyboard percussion tone, step 550 is NO and step 5
Go to step 57 without performing 6. This is because the keyboard percussion sound is attenuated and sounded without any special key-off processing, so that the processing of step 56 is unnecessary. Note that when the keyboard percussion sound is generated, it may be generated by a dedicated percussion sound generation channel or device without being assigned to the 16 channels that generate the scale sound.

--Sound Generation of Sequence Tone-- When a desired pad is turned on, as described above, the pad on event processing of FIG. 6 starts, and the pad mode data PM from the pad memory PDM corresponding to the pad is started.
(PN) is read and it is checked whether or not it is "0" (step 38). If the pad mode selected corresponding to the pad is the sequence tone generation mode, PM (P
N) = “1”, the process goes to step 41, and the sequence sound generation process is started. In step 41, the pointer P (PN) in the pad memory PDM (PN) of the turned-on pad is set to 0 to indicate the first event ranking. Next, from the sequence data area (see c in FIG. 2) of the pad memory PDM (PN), the pointer P
Event data E (PN, 0) and duration data D of the first event order designated by (PN) = 0
(PN, 0) is read and the event data E (PN,
Sound generation processing of the sound corresponding to the key code indicated by 0) is performed (step 42). This tone generation processing is almost the same as the processing of steps 39 and 40 described above, and the key code indicated by the event data E (PN, 0) is assigned to any channel to generate the tone signal generation circuit 17
The key code, the key-on signal, and the pad tone color data PTC (PN) are sent to the channel of, thereby making one tone signal corresponding to the key code of the tone signal generating circuit 17 into tone color data. Form with the corresponding tone color and have it sound. Further, the tone generator channel flag TGCHF corresponding to the assigned channel is turned on.

In step 43, it is checked whether the read duration data D (PN, 0) is an end mark code. If NO, go to step 44, and set the duration data D (PN,
0) is added and the addition result is stored in the next event time register NEXT (PN) corresponding to the pad number PN. The value of NEXT (PN) indicates the time when the next event will occur. After that, the pointer P (P
The value of N) is incremented by 1 (step 45). If the read duration data D (PN, 0) is the end mark code, the process goes to step 46 to perform a predetermined sequence end process. Here, processing necessary for ending the generation of the sequence sound, for example, if the key-off signal has not been issued yet, the key-off signal is given to the tone signal generating circuit 17, or the pad memory PDM corresponding to the pad number PN. Processing such as turning off all sound source channel flags TGCHF in (PN) is performed. Then, the value of the pointer P (PN) is set to the predetermined end value & HFF, and the process is ended (step 47). As described above, in the case of a pad-on event, the sequence sound of the first event sequence assigned to the pad is generated. The processing of the second and subsequent events is performed in the sequence control processing of FIG. This sequence control process is repeated every time the main routine is repeated.

In the case of the play mode or the mode of allocating a plurality of sounds, since PAM = 0 or PAM = 1, the process branches from step 96 to step 104 in FIG. In step 104, the pad number register PN is preset to 0. Next, at step 105, the pad mode data PM (PN) and the pointer P (PN) are read from the pad memory PDM (PN) designated by PN, and PM is read.
It is checked whether (PN) = "1" and P (PN) ≠ & HFF. If the tone generation mode assigned to the pad number PN is not the sequence tone generation mode, or if the pointer P (PN) is set to the predetermined end value & HFF even in the sequence tone generation mode, step 10
6 and checks whether the pad number PN has reached the maximum value of 4. If it has not reached yet, the routine proceeds to step 107, where the pad number PN is incremented by 1. Then, returning to step 105, the above judgment is made for the pad number PN incremented by 1.

The tone generation mode assigned to this pad number PN is the sequence tone generation mode and the pointer P
If (PN) is not already set to the predetermined end value & HFF, step 105 is YES and step 1
08, register NEXT pointed to by PN
Next event time data is extracted from (PN) and compared with the current value of timer TIME. When the current value of the timer TIME coincides with or exceeds the next event time NEXT (PN), the process proceeds to step 109, but the current value of the timer TIME still has the next event time NEXT (P).
If N) has not been reached, the process goes to step 106, and the loop of steps 106, 107 and 105 described above is repeated. When the above-mentioned check is completed for all the five pad numbers, PN = 4 becomes YES, and this sequence control process ends.

While the sequence control process is repeated several times, the current value of the timer TIME becomes the next event time NE.
When XT (PN) is reached, step 108 becomes YES and the process goes to step 109. In step 109, P
The current value of the pointer P (PN) of the pad memory PDM (PN) designated by N is read out, and the pad memory PDM (PN) is read.
Event data E (PN, P (PN)) and duration data D (PN, P (PN) of the event order designated by the pointer P (PN) from the sequence data area of DM (PN) (see c in FIG. 2). )) Read
The sound generation process or the muffling process of the sound corresponding to the key code indicated by the event data E (PN, P (PN)) is performed. When the flag of the event data E (PN, P (PN)) is an on flag indicating key depression, sound generation processing is performed, and when it is an off flag indicating key release, mute processing is performed. This tone generation process is almost the same as the process of step 42 described above, and the key code indicated by the event data E (PN, P (PN)) is assigned to any channel,
The key code, key-on signal, and pad tone color data PTC (P
N) is sent out, whereby one tone signal corresponding to the key code is formed and generated in the tone color corresponding to the tone color data in the channel of the tone signal generating circuit 17. Further, the tone generator channel flag TGCHF corresponding to the assigned channel is turned on. In the sound deadening process, a key-off signal is sent to the tone signal generating circuit 17 corresponding to the channel to which the key code relating to the off-event indicated by the event data E (PN, P (PN)) is assigned. Which channel is assigned is determined by the sound source channel flag TGCHF. It is preferable to turn off the tone generator channel flag TGCHF for the channel that has transmitted the key-off signal.

In this way, in the case of the off event, the mute processing is performed in step 109, and the sequence sound related to the off event that has been generated until then is muted. Also,
In the case of an on-event, sound generation processing is performed in step 109, and a new sequence sound is generated. Step 110
Then, the read duration data D (PN, P
(PN)) is the end mark code. N
If O, go to step 111 and set the duration data D (PN, P (PN)) to the current value of the timer TIME.
Is added and the addition result is stored in the next event time register NEXT (PN) corresponding to the pad number PN. Then, the value of the pointer P (PN) pointed to by PN is incremented by 1 (step 112). If the read duration data D (PN, P (PN)) is the end mark code, the process goes to steps 113 to 114, and a predetermined sequence end process and pointer similar to those in steps 46 and 47 (FIG. 6) described above. Perform reset processing.
As described above, a plurality of tones assigned as sequence tones are sequentially sounded according to the event data and the duration data stored in the sequence data area.

--Second Embodiment-- In the above embodiment, the performance operators, that is, pads P0 to P4.
Only sound source signals such as scale tones and rhythm sounds can be assigned to, and only setting information of the tone color switch can be simultaneously assigned to setting operators. next,
As a second embodiment, not only the tone color setting operators but also the setting states of various setting operators for setting the volume and various effects are assigned corresponding to arbitrary performance operators, that is, pads P0 to P4. An embodiment that enables the above will be described. It can be considered that the hardware configuration diagram of the electronic musical instrument according to the second embodiment is similar to that of the first embodiment, as shown in FIG. Further, the details thereof generally follow the examples of FIGS. 2 to 13, but are modified in some points as described below. The changed portions will be described below, and the points that are not described may be considered to be the same as those in the first embodiment unless a particular inconvenience occurs.

These setting operators are provided in the panel switch circuit 15. An embodiment of a part of the panel switch circuit 15 will be described with reference to FIG. The automatic accompaniment switch AASW is a switch for selecting an automatic accompaniment function such as automatic bass chord performance. The auto harmony switch AHSW is a switch for selecting to add the auto harmony effect. The auto harmony effect is to obtain a harmony effect by automatically adding an auto harmony sound, that is, an automatic performance sound to a sound being played.

Explaining the auto harmony effect in a little more detail, for example, a chord played on a keyboard or the like is detected, and a sound to be added is determined according to the type of the chord and the auto harmony type designation data separately designated. Examples of auto harmony types include duet, trio, octave, and strum. The duet is lower (or higher) by a predetermined pitch than the main performance sound (for example, melody sound) to be added 1
This is the effect of automatically adding two sounds. The trio is an effect of automatically adding two different sounds lower (or higher) by a predetermined pitch to the main performance sound (for example, melody sound) to be added. Octave is an effect of automatically adding a sound lower (or higher) by one octave to a main performance sound (for example, a melody sound) to be added. The strum is an effect of automatically adding a plurality of different arpeggio sounds lower (or higher) by a predetermined pitch to the main performance sound (for example, melody sound) to be added. The types of duet, trio, octave, strum, etc. are not limited to one type, and there may be a plurality of types depending on the pitch difference and pattern difference of the notes to be added. The types of playing chords are
It is used to determine the pitch of the added automatic sound. The main performance sound to be added is, for example, a melody sound, which is, for example, the highest pressed key in the melody performance keyboard or keyboard. Alternatively, when a sound assigned to a pad is sounded, these auto harmony sounds may be added to the pad assigned sound. Alternatively, it may be possible to automatically determine whether or not the sound currently being generated is a pad-assigned sound, and add the auto-harmonic sound only to the pad-assigned sound.

Returning to FIG. 14, the auto harmony type setting switch AHTP is a switch for setting the above auto harmony type, and is composed of, for example, an increment switch and a decrement switch. The numerical data displayed on the data display DPY increases or decreases in response to the pressing operation of the increment switch or the decrement switch of the type setting switch AHTP, and the desired auto harmony type can be selected. In addition, like the above-mentioned pad assign switch PASW and keyboard percussion switch KPSW,
A light emitting diode LED is provided corresponding to each of the automatic accompaniment switch AASW and the automatic harmony switch AHSW, and lights up when the automatic accompaniment or the automatic harmony effect is turned on. Volume switch VOLM
Is a switch for setting the volume level of a musical sound, and includes, for example, an increment switch and a decrement switch. The numerical data displayed on the data display DPY is increased or decreased according to the pressing operation of the increment switch or the decrement switch of the volume switch VOLM, and the desired volume can be set.

In the following, as an example, the volume information set by the volume switch VOLM, the auto harmony switch AHSW and the type setting switch AHT are set.
An example will be described in which the auto harmony setting information set by P can be assigned to any performance operator, that is, pads P0 to P4.
First, in this second embodiment, data and working R
The storage data format of the pad memory in the AM 12 is as shown in FIG. FIG. 15 corresponds to FIG. 2, a is the same as FIG. 2, but b and c are changed respectively. That is, the storage data format of the pad memory (PDM) in the simultaneous tone generation mode is as shown in b of FIG. 15, and is different from the case of b in FIG. (P
A storage unit for storing N) as header data (setting data common to sounds assigned to the pad) is added.
Volume setting data VOL (PN) is the pad number PN
This is volume information set by the volume switch VOLM corresponding to the pad. Auto Harmony Data AH
(PN) is auto harmony setting information (auto harmony on / off setting data and auto harmony type setting data) set by the auto harmony switch AHSW and the type setting switch AHTP corresponding to the pad of the pad number PN.

An example of the storage data format of the pad memory (PDM) in the sequence tone generation mode is as shown in c of FIG. 15, and similarly to the above, as compared with the case of c of FIG. A storage unit for storing PN) and the auto harmony data AH (PN) as header data is added. In addition, the setting information of these timbres, volume, and auto harmonies is the event data E (PN,
p) is stored in the sequence data area. That is, in this example, not only the key-on and key-off, but also changes in the tone color switch, the volume switch VOLM, the auto harmony switch AHSW and the type setting switch AHTP in the panel switch circuit 15 are detected as an event for sequence sound generation control, and the sequence is controlled. It is designed to be stored in the data area. Therefore, in the format of c in FIG. 15, the event data E (PN, p) is composed of an event code and data indicating the data content related to the event. The event code is a code indicating an event type such as key-on, key-off, tone color, volume (volume), auto harmony on / off, auto harmony type. The event data content is data showing specific data content such as a key code, tone color code, volume setting data, and auto harmony type setting data. As before,
Duration data D (PN, p) indicating the time interval from the event to the next event is also stored.

When the sequence sound is generated, the sequence sound is initially set as tone color, volume and auto harmony setting information PTC (PN), VO stored as header data.
It is controlled according to L (PN) and AH (PN), but with the passage of time, the event data E (PN, p) is read out, and the event data changes the setting state such as tone color, volume, auto harmony, etc. If the corresponding information is included, control is performed so as to change the setting state of the tone color and volume of the sequence sound thereafter, or the setting state of the auto harmony effect added to the sequence sound.

FIG. 16 shows the main routine, and the point different from the main routine of FIG. 3 is that the processing for automatic accompaniment and auto harmony is specified. That is, if the automatic accompaniment is turned on, the process for the automatic accompaniment is performed, and then it is checked whether the auto harmony is set to the on state, and if so, the process of adding the auto harmony sound is performed. If automatic accompaniment is not turned on, no auto harmony sound is added. In the initial setting process, the pointers P (0) to P (P) in the pad memory (PDM) corresponding to the pads P0 to P4 are used.
A predetermined end value & HFF is written as the instruction value of (4). This is because the sequence tone generation mode of each pad is initially set to a stopped state.

--Processing in the plural tone allocation mode--
In this case, the pad-off event process of FIG. 7 is changed as shown in FIG. 19 as the process related to the multiple sound allocation mode. In FIG. 19, step 60 is followed by step 60
7 is different in that 1 is inserted, and the rest is the same as the processing in FIG. 7. First, as described above, the pad assign switch PASW is operated to set the pad assign mode PAM to 1. Also, at an appropriate time, the panel switch circuit 15 selects a desired timbre, sets the volume switch VOLM to a desired value, and sets the switches AASW, AHSW, AHTP.
Desired selection for automatic accompaniment and auto harmony in /
Make settings. The selection / setting state of these setting operators is detected and scanned by the panel switch processing of the main routine and stored in an appropriate buffer register. Then, in the same manner as described above, the desired pad to be assigned is turned on, one or more desired keys to be assigned to the pad are pressed, and then the pad that has been turned on is turned off.

Then, step 5 in the processing of FIG.
From YES in 8 to step 59, after confirming that there is a key being depressed, the processes of steps 60 to 62 are performed.
In the processing here, as described above, the data is written in the pad memory PDM corresponding to the turned off pad (pad number PN = i). That is, in step 60,
The pad mode data PM (i) is set to "0" to register the simultaneous tone generation mode, and the tone color code TC of the tone color set by the tone color switch is registered as the pad tone color data PTC (i). Next step 601
Then, the volume setting information set by the volume switch VOLM is registered as the volume setting data VOL (i) corresponding to the pad (pad number PN = i), and the auto harmony on / off set by the auto harmony switch AHSW is performed. The OFF setting information and the auto harmony type setting information set by the type setting switch AHTP are registered as the auto harmony data AH (i) corresponding to the pad (pad number PN = i). Then, the processing of steps 61 and 62 similar to the above is performed. In this way, the volume and auto harmony setting information is registered as header data in the format shown in FIG.

--- Processing at the time of assigning sequence sounds --- In the case of the second embodiment, the key-on event processing of FIG. 4 is modified as shown in FIG. 17 as the processing related to the assignment of sequence sounds. FIG. 17 differs from FIG. 4 in that step 691 is inserted after step 69, and the other points are the same as the processing in FIG. However, in the normal sound generation process of step 50, the volume data buffer VO described later is used.
The volume of the generated sound is controlled according to the LBUF data.
The process of step 691 is the same as step 601 of FIG. 19 described above.
This is the same processing as the processing of. By adding the processing of this step 691, as in the above, in the pad memory PDM corresponding to the pad (pad number PN = i) to which the sequence sound is assigned, the volume setting data in the format shown in FIG. VOL (i) and auto harmony data AH (i) are registered as header data. That is, the volume and auto harmony data to be set as the header data are set in advance in a desired state by the volume switch VOLM and the switches AHSW and AHTP. Then, as described above, the pad assign mode is set to PAM = 2 and the first key of the sequence sound is pressed. Then, step 5 of FIG.
In 3, it is determined that PAM = 2, and the processes of steps 68 to 73 are performed. In the process, the process of step 691 is performed, and the volume setting data VOL (i) and the auto harmony data AH (i) are registered as header data.

21. In order to store the setting data such as tone color, volume and auto harmony as event data in the pad memory PDM corresponding to the time change when allocating a sequence tone, as shown in FIG. Setting operator event processing as shown in is performed. Tone switch or volume switch VOLM
Alternatively, when the selection / setting state by the auto harmony switch AHSW or the auto harmony type setting switch AHTP is changed, the event processing of FIG. 21 is started. In FIG. 21, step 120
Now, check the pad assign mode PAM. If the PAM is 0, 1 or 2, this event processing is immediately terminated. When PAM = 3, that is, in the sequence tone allocation storage mode, the processing of steps 121 to 129 is performed. The processing in steps 121 to 129 is similar to the processing in steps 74 to 79 and 93 to 95 in FIG. That is, in step 121, the value of the old time register OLDT is subtracted from the current value of the timer TIME, and the difference between the previous event occurrence time and the current event occurrence time,
That is, the event time interval is obtained and stored in the duration register D. Next, the sequence data area in the pad memory PDM corresponding to the pad number i (see FIG.
5c), the duration data D (i, P) of the event order designated by the pointer P (i).
As (i)), the time interval data stored in the duration register D is stored (step 122). For example, if P (i) = 0, the time interval data of the duration register D is stored as the duration data D (i, 0) of the first event ranking. Next, the pointer P
(I) is incremented by 1 and the next event ranking (that is, the ranking of the current event) is designated (step 123).

At the next step 124, in the sequence data area (see c of FIG. 15) in the pad memory PDM corresponding to the pad number i, the event data E of the event order designated by the pointer P (i)
As (i, P (i)), an event code indicating the type of the setting operator event this time and event content data indicating the setting state are written. In the next step 125, it is checked whether the value of the pointer P (i) has reached the maximum value 19. N
If it is O, go to step 126 and set the current value of the timer TIME in the old time register OLDT,
As a result, the time at which this event occurred is stored. In this way, the duration data D (i, P (i)) relating to the previous event ranking and the event data E (i, P) relating to the current event ranking corresponding to the event (change in setting state) of the setting operator. (i) +1) is written. When the value of the pointer P (i) becomes the maximum value 19 due to the increment in step 123, step 125 becomes YES, and the processing of steps 127 to 129 exactly the same as the processing of steps 93 to 95 in FIG. 4 is performed. , Pad assignment processing ends.

--Processing at Playback Sound Generation-- In the case of the second embodiment, the pad-on-event process of FIG. 6 is changed as shown in FIG. 18 as a process related to the playback sound of the pad assigned sound. In FIG. 18, step 130
~ 134 has been added. Also, step 3 in FIG.
In FIG. 18, 9 and 42 are changed to steps 390 and 420. First, the case of the simultaneous sound generation mode will be described. When the desired pad is turned on, the pad on event process of FIG. 18 starts. In the simultaneous tone generation mode, the pad mode data of the turned-on pad is PM (P
Since N) = 0, YES is determined in step 38 in FIG. 18, and steps 130, 131, 390,
40 processing is performed. In step 130, the volume setting data VOL (PN) is read from the pad memory PDM (PN) corresponding to the turned-on pad and stored in the volume data buffer VOLBUF. In step 131, the pad memory PDM corresponding to the turned-on pad
The auto harmony data AH (PN) is read from (PN), and on / off data and type data of the auto harmony effect are set / stored in a predetermined buffer register in response thereto. In step 390, as in step 39 of FIG. 6, the pad tone color data PTC (PN) and the pad assigned tone data PAT are read from the pad memory PDM.
(PN) is read, a plurality of tones corresponding to the pad assigned tone data are assigned to different channels, and tone signals of these tones are formed by the tone colors corresponding to the pad tone color data and generated. 6 is different from step 39 in FIG. 6 in that the volume of the plurality of pad sounds is controlled by the volume setting data of the volume data buffer VOLBUF.

The adding process of the auto harmony sound is performed in the main routine (FIG. 16) according to the ON / OFF data and the type data of the auto harmony effect stored in the predetermined buffer register in step 131. In this way, a plurality of tones assigned to the pad are sounded, and the volume setting state and the auto harmony effect setting state that are assigned and stored corresponding to the pad are reproduced, and the pad is set according to the reproduced volume setting data. The volume of the sound is controlled, and additional control of the auto harmony sound according to the reproduced auto harmony effect setting state is performed. Next, the case of the sequence tone generation mode will be described. If the pad mode corresponding to the pad that has been turned on is the sequence tone generation mode, PM (PN) = “1”, so in FIG. 18, NO is determined in step 38, and the routine proceeds to step 132. In step 132, it is checked whether or not the value of the pointer P (PN) corresponding to the turned-on pad is the predetermined end value & HFF. In the initial setting process in the main routine of FIG. 16, the pointers of all pads are initially set to & HFF, and also when the sound generation control of the sequence sound is completed, the pointers are set to & HFF. Therefore, the value of the pointer P (PN) is & H.
Being FF means that the sequence sound is not being sounded. That is, step 132 of FIG.
If P (PN) = & HFF is determined to be YES in,
It means that the pad-on operation this time is to start the generation of the sequence sound. Therefore, if step 132 is YES, after performing the processing of steps 133 and 134, it proceeds to step 41 and starts the sound generation processing of the sequence sound.

The processing of steps 133 and 134 is the same as the processing of steps 130 and 131. That is, the pad memory PDM corresponding to the turned-on pad
(PN) to read the volume setting data VOL (PN), store this in the volume data buffer VOLBUF, and also read the auto harmony data AH (PN), and according to this, turn on / off the auto harmony effect data and type. Data is set and stored in a predetermined buffer register. In step 41, the pointer P in the pad memory PDM (PN) of the turned-on pad is
Set (PN) to 0 to indicate the first event ranking. In the next step 420, the pointer P (PN) = 0 from the sequence data area (see c in FIG. 15) of the pad memory PDM (PN), as in step 42 in FIG.
Event data E (PN, 0) and duration data D (PN, 0) of the first event order designated by
Is read out, and the sound corresponding to the key code indicated by the event data E (PN, 0) is sounded.
It is different from step 42 of FIG. 6 in that it is controlled by the volume setting data of LBUF. Continued steps 43-4
The process of 5 is the same as that of FIG.

As described above, the process of producing the sequence sound of the first event order assigned to the pad is performed. The processing of the second and subsequent events is performed in the sequence control processing of FIG. 20 is almost the same as that of FIG. 11, and only step 109 of FIG. 11 is partially changed, which is shown as step 1090 in FIG. As described above, when the current value of the timer TIME reaches the next event time NEXT (PN), step 1
08 becomes YES, and the process goes to step 1090. In step 1090, the pad memory P designated by PN
The current value of the pointer P (PN) of DM (PN) is read, and the event data of the event order designated by the pointer P (PN) is read from the sequence data area of the pad memory PDM (PN) (see c in FIG. 15). E (P
N, P (PN)) and duration data D (PN, P)
(PN)) and reads the event data E (PN, P
(PN)) sound generation processing or mute processing of the sound corresponding to the key code, or setting processing of tone color, volume, effect, etc. is performed. The event data E (PN, P (P
If the event code of N)) indicates a key depression, sound generation processing is performed, and if the event code indicates key release, mute processing is performed. During this pronunciation processing, the volume of the generated sound is set to the volume data buffer VOLBU.
It is controlled by the volume setting data of F. When the event code of the event data E (PN, P (PN)) indicates an event of various setting operators, the setting data content is changed by the event content data accompanying it. That is, if the event code is a volume event,
The volume setting data stored as the event content data is stored in the volume data buffer VOLBUF.
If the event code is an auto harmony event, the auto harmony data stored as the event content data (that is, ON / OFF data or type data of the auto harmony effect) is set and stored in a predetermined buffer register. Subsequent steps 110 to 11
The process of 4 is the same as that of FIG.

In this way, a plurality of sequence tones assigned to the pads are sequentially sounded, and the tones, the volume, and the tone assigned to the pads are stored in correspondence with the time change.
The setting state of the auto harmony effect etc. is reproduced over time, the tone color and volume of the pad sound is controlled according to the reproduced tone color and volume setting data, and the auto mode according to the reproduced auto harmony effect setting state is set. Harmony sound addition control is performed. Note that in the example of FIG. 20, when the sequence sound corresponding to an arbitrary pad is being sounded, if the pad is pressed once again, the process of automatically stopping the sounding of the sequence sound is devised. That is, the pointer P (P
Since N) is a value other than & HFF, when the same pad is pressed again, step 132 in FIG.
Then, it is determined to be NO. This results in steps 46 and 4
7, the sequence end process is performed, and the pointer P (P
Set N) to & HFF.

--Modification-- In both cases of the multiple sound allocation mode and the sequence sound allocation mode, the details of the allocation processing method are not limited to those in the above-described embodiment, but can be modified appropriately. Further, the process of assigning a plurality of sounds or sequence sounds to the pads and other various processes are not limited to the software process using the microcomputer as in the above-described embodiment, but may be performed by a dedicated hardware circuit. The performance operator to which a plurality of tones can be assigned is not limited to the pad (operator having an elastic operation surface) shown in the above embodiment, and any other operator may be used. Further, the sensor of the performance operator may detect not only the on / off of the operation but also an operation touch and control the generated sound according to the touch.
As a means for selecting and designating a desired assigned sound, a keyboard, a tone color designating switch or the like is used in the above embodiment, but the invention is not limited to this, and other appropriate data input means or the like may be used. In the above-described embodiment, in the plural-sound allocation mode, desired one to plural sounds are simultaneously allocated and stored. However, the present invention is not limited to this, and it is also possible to add or delete desired sounds one by one. In the sequence sound assignment mode, the time data (duration data) between each event is set according to the key playing operation in the above embodiment, but the present invention is not limited to this, and the data input is separately performed by an appropriate data input means or the like. You may do it. Further, the maximum number of sequence sounds, the phrase time length, and the like are not limited to those in the embodiment, and can be changed as appropriate. The technique of storing the setting information by the setting operators such as volume and effect corresponding to the performance operators such as pads is the technique of assigning a plurality of sounds to the performance operators such as pads as described in the above embodiment. The present invention is not limited to combination, but can be applied to a musical instrument such as a pad in which only one sound is assigned.

As described above, according to the present invention, it is possible to assign an arbitrary plurality of sounds corresponding to one performance operator in the assignment mode. In that case, when the performance operator is in the operating state. It is possible to change the assignment by assigning an arbitrary musical sound designated to be assigned to the operator and changing the musical tone to be assigned, and when the operator changes from the operating state to the non-operating state, The assignment is fixed. Therefore, 1
It is possible to perform an operation for assigning a plurality of arbitrary sounds to one performance operator with a margin, and it is very easy to assign a plurality of sounds. Also,
The plurality of tones assigned to the performance operator are sounded simultaneously by the tone signal generating means when the performance operator is operated. Therefore, if desired plural tones are assigned to the performance operator for each performance opportunity in accordance with the music to be played at that time, when the plural tones are to be generated, the performance operator is operated only once. The excellent effect that the desired plural tones can be easily pronounced at the same time is achieved. In addition, a plurality of performance operators and a first mode in which a plurality of tones are simultaneously generated in response to an operation of one performance operator and a first mode in which a plurality of tones are sequentially generated in response to an operation of one performance operator. By providing the mode selecting means capable of selecting the two modes, it is possible to easily perform both a multi-tone simultaneous performance such as a chord and a sequence sound performance according to the mode selected corresponding to each operator. Since it becomes possible to perform a mixture of performances in two different modes, an excellent effect of greatly improving performance performance can be achieved.

Further, when assigning arbitrary plural tones to the performance operator, various setting operators such as volume and effect are set to desired setting states, and this setting information is also stored and stored thereafter. In response to the operation of the performance operator, a plurality of musical tones corresponding to the sounds assigned to the performance operator are simultaneously pronounced, the stored setting information is read, and the tone control according to the setting information is performed. Since the effect imparting control is performed, the desired setting state of each setting operator can be reproduced at once when the assigned sound is reproduced and reproduced. The effect of setting various effects to be added is easy, the reproducibility is excellent, and the performance can be further improved. Further, when a plurality of performance operators are provided, different setting states can be assigned to the respective performance operators, so that the performance can be improved in this respect as well. For example, when a plurality of performance operators are simultaneously operated to generate assigned sounds, musical tones can be controlled or effects can be given in different setting states for each sound corresponding to each performance operator. No playing effect is obtained. Further, while a plurality of arbitrary tones are sequentially assigned in an arbitrary pronunciation order corresponding to the performance operator, at least one of the setting operator means is associated with this assignment.
The information indicating the setting state of one operating element is stored together with the time change of the setting state, and when this performance operating element is operated,
A plurality of sounds assigned to the performance operator are sequentially generated, and the change of the setting state is reproduced over time based on the memory of the storage means, and the tone control or effect according to the reproduced setting state is performed. Since the addition control is performed, not only can the sequence sound be played easily, but also the setting state for various tone control or effect addition control can be automatically and sequentially changed. In addition to the unprecedented playing effect, it is easy to operate and has excellent reproducibility.
