Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance control device for recording input operation information as a series of performance patterns and controlling the reproduction of the performance patterns.

[Prior Art and Problems to be Solved by the Invention] As a performance control device used in a conventional electronic musical instrument,
An effect adding device such as a delay machine, or a device such as a sequencer for recording and reproducing a series of performance patterns of performance information is known. However, a general effect adding device can add an effect to a musical sound, for example, an effect of delaying the sounding timing of the musical sound, but cannot transpose the pitch of the musical sound to an arbitrary range. Although a sequencer can record and reproduce a series of performance patterns, the recorded pitch data (key code) is an absolute pitch, and it can be transposed into an arbitrary pitch range during playback. I can't. In this case, the key transpose switch of the electronic musical instrument can be operated separately to transpose each semitone in a limited range of, for example, one octave to reproduce the performance pattern.
There is a problem that it is not possible to immediately transpose to a desired pitch (key) and reproduce it by one operation. Further, according to the conventional sequencer, data for controlling musical tone characteristics such as key touch data can be recorded / reproduced, but the reproduced pattern to be reproduced is controlled by the recorded key touch data as it is. Therefore, there is a problem in that it is not possible to change the control characteristic such as an arbitrary key touch at the time of reproduction to reproduce the performance pattern.

[Object of the Invention] The present invention has been made to solve the above-mentioned problems, and records input performance information as a series of performance patterns, and transposes the recorded performance patterns into an arbitrary musical range, or arbitrarily. It is an object of the present invention to obtain a performance control device capable of reproducing and performing after changing the musical tone characteristics (volume / timbre) at the time of sounding.

[Points of the Invention] A first point of the present invention is a performance information input means for inputting performance information including touch data for controlling the tone characteristics of a tone to be generated, and one of the input mode and the playback mode. Of the touch data sequentially input by the performance information input means when the mode designating means for designating
Conversion storage means for converting the touch data input first as reference touch data into touch data input thereafter and converting the touch data into differential touch data indicating a difference value with the reference touch data, and storing the conversion data. When the playback mode is designated, the touch data input first by the performance information input means is used as the reference touch data, and the reference touch data is sequentially added to the differential touch data read from the conversion storage means. Then, there is provided a generation means for generating new touch data and a performance control means for performing a performance based on the performance information including the new touch data generated by this generation means.

A second important point of the present invention is to provide performance information input means for inputting performance information including pitch data of a musical tone to be generated and touch data for controlling musical tone characteristics, and one of an input mode and a reproduction mode. Of the pitch data and the touch data sequentially inputted by the performance information input means when the mode designating means designates the input mode. As the reference pitch data, the pitch data input after that is converted into the difference pitch data with the reference pitch data and stored, and the touch data input first is used as the reference touch data. The conversion storage means for converting the touch data input thereafter to the touch data different from the reference touch data and storing the converted touch data, and the mode designating means for the reproduction mode. The when it is specified first pitch data and the touch data is inputted to the reference pitch data and the reference touch data in the performance information input means,
Of the differential pitch data and the differential touch data sequentially read from the conversion storage means, the reference pitch data is added to the differential pitch data to generate new pitch data, and the differential touch data is converted to the reference pitch data. Generating means for adding touch data to generate new touch data; and performance control means for performing a performance based on performance information including new pitch data and new touch data generated by the generating means. , Is to have.

[Embodiment] An embodiment of a control device for an electronic musical instrument according to the present invention will be described below with reference to the drawings.

<First Embodiment> Configuration FIG. 1 is an overall circuit configuration diagram of an electronic keyboard instrument according to a first embodiment. In the figure, a key on / off signal, key code data as pitch designating information of a musical tone to be generated, or strength at key depression based on key operation of a keyboard 1 which is a performance input means for inputting performance information. The velocity signal (touch data) corresponding to is given to CPU2 which is a central processing unit including a microcomputer. The switch group SW is a tone color selection switch 3 for designating a tone color of a musical tone, an edit made setting switch 4 for setting the mode of this musical instrument to an edit mode in which various data settings can be made, a pitch bend range setting mode designation switch 5, Value key 6 consisting of up key and down key for entering various data including setting of modulation depth and pitch bend range, performance pattern input mode key 7 for setting the mode for inputting a performance pattern, It is composed of a performance pattern reproduction mode key 8 for setting a mode for reproducing a performance pattern. An operation signal output by operating these switch groups SW is also supplied to the CPU 2.

Further, after-touch data for the keyboard 1 detected by the after-touch detection circuit 9 (data obtained by changing the pressing force in a key-pressed state)
However, the gate G1 and the A / D converter 1 which open at the time division time t1 in the time division timing signal t given from the CPU2
It is taken into CPU2 through 0. Further, the following functions are provided as effect information input means for adding an effect to a musical sound. That is, by turning on the modulation switch 11-1 in the modulation operation unit 11 and rotating the modulation wheel 11-2 from the front direction to the back direction, the depth of the vibrato effect on the musical sound is preset by the value key 6. Similarly, at time division time t2, a signal that gradually increases to the depth is captured by the CPU 2 via the gate G2 and the A / D converter 10.
When the modulation switch 11-1 is off, the modulation wheel 11-2 does not function, and a vibrato effect with a preset depth is added according to the tone color selected by the tone color selection switch 3. When the pitch bend wheel 12-1 in the pitch bend operation unit 12 as pitch bend means is rotated from the center position to the back, it is set by the operation of the value key 6 when the pitch bend range setting mode designating switch 5 is turned on, and once the RAM ( Data for gradually increasing the pitch of a musical tone within the range of the pitch bend range stored in the random access memory (13), for example, within one octave range,
At time division time t3, C is passed through the gate G3 and A / D converter 10.
Captured by PU2. Conversely, pitch bend wheel 12-1
When is rotated from the central position toward the front, data for gradually lowering the pitch of the musical sound within the range of a maximum of one octave is similarly fetched by the CPU2. Further, when the foot pedal 14 operated by the foot is operated, a signal for controlling the volume of the musical sound is transmitted at the time of the time division time t4 by the gate G4 and the A / D converter 1
It is taken into CPU2 through 0. Further, when the slide volume 15 is operated, a signal which also controls the volume of the musical sound is taken into the CPU 2 via the gate G5 and the A / D converter 10 at the time division time t5. The display unit 16 displays the operation state of the switches in the switch group SW by, for example, a liquid crystal display device.

The counter 17 as time information generating means counts the time interval between key-on of the keyboard 1 and other events under the control of the CPU 2 in the above-mentioned performance pattern input mode or performance pattern reproduction mode. is there.

And CPU2 is keyboard 1, switch group SW, A / D converter 1
Music tone control that executes processing for various information acquired from 0 or RAM 13 based on a program given from ROM (Read Only Memory) 18 and controls sound source section 19 to generate and mute musical tone signals Signal (key on /
OFF information, pitch designation information, etc.) is transmitted. The tone signal output from the sound source unit 19 is converted from a digital signal to an analog signal by the D / A converter 20, and is emitted as a tone through the amplifier 21 and the speaker 22.

Operation Next, the operation of the electronic keyboard musical instrument according to the first embodiment having the above-described configuration will be described focusing on the processing operation of the CPU 2.

FIG. 2 is a flow chart of performance pattern input processing showing a processing operation of storing performance information input by the keyboard 1 which is performance information input means in the RAM 13 as a performance pattern together with time information indicating timing at which the performance information is input. is there. This flow is started by interrupting the main flow (not shown) in the CPU 2 when the performance pattern input mode key 7 is turned on. First, it is checked whether or not 1 is set in the fundamental tone flag in order to set the pitch of the musical tone first depressed (key-on) after the performance pattern input mode key 7 is turned on (step S1). Here, since the fundamental tone flag is initially reset, it is determined to be NO, and then it is checked whether or not the key-on is actually performed (step S2). If NO is determined, it means that the first key-on for actually inputting the performance pattern has not been made yet, so the process returns to the main flow, but the key-on is made.
When YES is determined, the counter 17 is subsequently reset (step S3). Then, in order to generate a musical tone based on the key code corresponding to the key-on, the musical tone pronunciation instruction is issued.
Perform for 19 (step S4). Then, the fundamental key flag that makes it clear that the first key-on has been performed is set (step S5), and first, in order to obtain the difference key code information that is the difference value information with the key code corresponding to the subsequent key-on, The fundamental key code corresponding to the key-on is read (step S6), and the process returns to the main flow.

Then, if there is a change in various switch states in the switch group SW, a process corresponding to the change is performed in the main flow, and then the flow is entered again. Since the fundamental flag has already been set this time, it is determined that the basic flag = 1 is YES (step S1), and then the event (key on / off,
It is checked whether or not performance information such as pitch bend is input) (step S7). If NO, it is not necessary to input any performance pattern, so the process directly returns to the main flow. If YES, it means that there is some event for inputting the performance pattern, and the count value of the counter 17 that was reset earlier, that is, the elapsed time from the time when the key was first turned on to the time when this event occurred Read and reset the count 17 (step S8). Then, it is checked whether or not the previous event was a key-on (step S9), and if it is a key-on, it is determined to be YES, and an instruction to sound the tone corresponding to the key-on is sent to the tone generator section 19 (step S1).
0). After that, the difference value between the key code based on the second key-on and the fundamental key code (the key code corresponding to the first key-on) previously read in step S6 is calculated to calculate the difference between the second key-code and The data is converted into the data of the differential key code which is the result of this calculation (step S1
1). This differential key code is written in the first address area of the RAM 13 as the first data of the performance pattern (step S12), and the differential key code based on the next third key-on is written in the second address area of the RAM 13. Therefore, the memory address of the RAM 13 is incremented by 1 (step S13), and the process returns to the main flow. If it is determined in step S9 that the event is not key-on, an instruction other than the start of sound generation, for example, a pitch bend instruction to mute or add an effect to a musical sound is sent to the sound source section 19 (step S1
4) Proceed to step S12 described above, and write the information such as the mute or pitch bend together with the time information indicating the timing of each event in the RAM 13 as the data for forming the performance pattern. Similarly, the address of the RAM 13 is set to 1 only. Increment (step S13),
Return to the main flow.

Subsequently, the same processing operation is repeated for the third and subsequent events based on this flow, and a differential key code, mute, or other information is stored in the RAM 13 as a series of performance patterns each time this event occurs.

FIG. 3 is a performance pattern reproduction processing flow chart showing the processing operation relating to the reproduction of the performance pattern stored in the RAM 13 based on the above-mentioned flow. This flow is different from the main flow in the CPU 2 in the performance pattern reproduction mode. When key 8 is turned on, it interrupts and starts. First, it is checked whether or not 1 is set in the fundamental tone flag (step T1), but since the fundamental tone flag is initially reset, it is determined to be NO. Then, check whether the key is turned on (step T2),
If NO is determined, it means that the first key-on for reproducing the performance pattern, that is, the case where the reference performance information is not input, does not need to be reproduced yet, and the process directly returns to the main flow. However, if YES is determined, it means that the first key-on for inputting the reference performance information is performed for reproduction, so first, the counter 17 is reset to prepare for counting the elapsed time until the next event ( Step T3). Subsequently, the tone generator section 19 is instructed to generate a tone corresponding to the first key-on, that is, the fundamental tone (step T4), and the fundamental tone flag is set to 1 to clarify that the reference performance information has been input. (Step T5). Then, in order to start the reproduction of the performance pattern based on the next key-on, the key code corresponding to the current key-on is read as the fundamental key code, that is, the reference performance information (step T6). Further, the memory contents of the area corresponding to the first address among the count information as the performance information input in the above-described performance pattern input mode, that is, the various data and the time information which is the time interval between each event, is loaded from the RAM 13. After (Step T
7) Return to the main flow.

Then, after performing other processing as necessary in the main flow, when this flow is entered again, it is determined that the fundamental flag is already set to 1 (step T1), and the counter 17 has counted this time. The value is compared with the count value as time information in the performance pattern previously loaded in step T7 (step T8). If they do not match, this determination is repeated until they match, and if they match, the process shifts to the conversion process for the event data stored in the area corresponding to the first address in the previously loaded performance pattern.

First, it is checked whether or not the event data is key-on (step T9), and if it is determined to be YES, the key-code data loaded earlier was the difference key code with respect to the fundamental key code. In step T6, the key code read in step T6 is added to the difference code to perform the inverse conversion of the key code data. Get (step
T10). That is, in this step T10, the key codes obtained by inverse conversion based on the fundamental key code as the reference performance information are all the fundamental key code read by the first key-on in the performance pattern reproduction mode, that is, the pitch of the fundamental tone. As a reference, it is a key code obtained by moving the key code in the previously read performance pattern in parallel (transposing the pitch). And this step
The tone generator section 19 is instructed to generate a musical tone of a pitch based on the key code as the reproduction performance information obtained at T10 (step T1
1). Then, after resetting the counter 17 to prepare for the next event in the playing pattern (step T12), the RAM
The address of 13 is incremented by 1 and the data and the count value stored in the area corresponding to the second address of the RAM 13 are loaded in preparation for the next loading (step T14), and then the process returns to the main routine.

If it is determined that the key is not turned on in step T9,
An instruction based on event data other than key-on in the previously read performance pattern, for example, data such as pitch bend or key-off (silence) is sent to the tone generator section 19 (step T15).

After that, the process returns to the main routine at the same time through the steps T12, T13, and T14 described above, and the reproduction process of the previously read performance pattern is continued. When the performance pattern completes one cycle, the fundamental tone flag is reset and the system waits until the next key-on to reproduce the performance pattern. If there is a change in the operating state of any of the switches in the switch group SW during the playback of this performance pattern, the processing of this flow is temporarily interrupted and the necessary processing corresponding to the change of that switch is performed in the main flow. Run.

As described above, according to the electronic keyboard instrument of the first embodiment, in the performance pattern input mode, a series of phrases are played by pressing the keys of the keyboard 1, and their pitches are set to the fundamental tone based on the first key-on. RAM1 with the data of the counter value indicating the time interval between each key-on in order as the data of the difference key code indicating the difference value with the fundamental tone based on the pitch.
Data of events other than key-on, such as key-off, pitch bend, and other effect information, are stored in RAM 13 together with counter value data indicating timing.
To be stored. In the play pattern playback mode, RA is set based on the first key-on for playback, that is, the pitch (key code) of the fundamental note based on the input of the reference performance information.
The data of the performance pattern sequentially read from M13 is inversely converted to obtain the key code as the reproduction performance information, and the musical tone is sequentially generated from the tone generator section 19 so that the reproduction performance of a series of phrases based on the performance pattern is performed. I have to. Therefore, when playing a playing pattern, the player transposes the pitch to a desired range by arbitrarily selecting the pitch of the first key-on as the reference playing information that serves as a reference, and then playing the previously entered playing pattern. Can be played and played. That is, unlike the case where a so-called sequencer is used to record and reproduce a performance pattern, it is not necessary to perform a switch operation for key transposition many times, and only a single key-on operation transposes to an arbitrary range. In this state, the performance pattern can be automatically reproduced. Also, as the playing pattern, not only the key code information relating to the key on / off, but also the data for adding various effects such as pitch bend or modulation are stored in the RAM 13 together with the counter value indicating the timing of those events. , It is also possible to reproduce a performance pattern with various effects (effects) added to a musical sound.

<Second Embodiment> A second embodiment of the present invention will be described below.

Configuration The overall circuit configuration of the electronic keyboard instrument to which the second embodiment is applied is basically the same as the overall circuit configuration of the electronic keyboard instrument to which the first embodiment shown in FIG. Only the points will be explained. That is, in the second embodiment, the keyboard 1 as the performance information input means also outputs the touch data (initial touch data) corresponding to the strength of the key pressing operation as the detection output. However, it is configured to be taken into the CPU2 together with the data of the key code corresponding to the key on / off.

Operation Next, the operation of the electronic keyboard instrument according to the second embodiment will be described focusing on the processing operation of the CPU 2.

FIG. 4 is a performance pattern input processing flow chart showing the processing operation for storing the performance pattern, but the steps designated by the same reference numerals as in FIG. 2 previously described perform the same processing or judgment. However, description of that point will be omitted, and only points different from the operation of the first embodiment will be described. That is, when the first key-on for input is performed, not only the fundamental tone key code is read, but also the fundamental tone touch data, that is, the touch strength data at the first key depression is read (step S6-2). ). Also in the second and subsequent key-on, not only the conversion to the differential key code (step S11) but also the difference value between the touch data in the second key-on and the previously read fundamental tone touch data is calculated. As a subtraction operation (step S11-2), and the differential key code and the differential touch data are both written in the RAM 13 (step S1).
2).

FIG. 5 is a performance pattern reproduction processing flow chart showing the processing operation relating to the reproduction of the performance pattern stored in the RAM 13 based on the above-mentioned flow. Also in this flow, steps denoted by the same reference numerals as those in FIG. 3 perform the same processing or judgment, and the description of the points will be omitted and only the points different from the operation of the first embodiment will be omitted. explain. That is, when the first key-on is performed as the input of the reference performance information that is the reference data for reproduction, not only the fundamental key code is read but also the fundamental touch data, that is, the touch strength data at the first key depression. Is also read as reference performance information (step T6-2).
If it is determined in step T9 that the event data stored in the area of the first address from the RAM 13 is the key-on data, the read differential key code data is added to the fundamental key code and inverse conversion is performed. Not only (step T10), but also the differential touch data is added to the fundamental touch data and inversely converted to obtain touch data designating the strength of the musical tone to be generated (step T10-2). Further, for the differential key code and the differential touch data stored in the second and subsequent address areas of the RAM 13, the reverse conversion of the touch data is performed together with the reverse conversion of the key code data.

Thus, according to the electronic keyboard musical instrument of the second embodiment,
In the playing pattern input mode, a series of phrases is played by pressing the keys of the keyboard 1 and not only the data of the differential key code and the counter value but also the touch data at each key-on is stored as the differential touch data in the RAM 1
The data of various effect information by the operation of the effect adding means such as the modulation operation unit 11 is also stored in the RAM 13 together with the respective counter values. Then, in the playing pattern playback mode, RA is based on the pitch (key code) of the fundamental note and the chich data, which is the reference performance information based on the first key-on for playback.
The performance information data read from the M13 is inversely converted, and various effect information is also sequentially read, and the musical tone is generated by the tone generator section 19 with the effect added thereto, and the performance pattern is reproduced. Therefore, the performer can play back a series of pre-recorded performance phrases by optionally setting the strength at which tones are generated based on the touch data of the fundamental tone, and the automatic tune of more varied songs can be performed. Playback performance becomes possible.

<Modified Embodiment> In the above-described first embodiment, in the performance pattern input mode, the fundamental key code corresponding to the first key-on,
The key code of the difference value from each key code corresponding to each key-on in the performance pattern is sequentially stored in the RAM 13. However, instead of the difference key code with the first fundamental key code, the difference value with the key code corresponding to the immediately preceding key-on is subtracted and the difference key codes are sequentially stored in RAM 13, and in the playback performance mode, It is also possible to add the sequentially loaded difference key code to the key code immediately before being sounded to obtain the key code of the musical sound to be sounded by sequential reverse conversion.

Similarly, in the above-described second embodiment as well, in the performance pattern input mode, the immediately preceding key-on is not converted into the key-tone key code corresponding to the first key-on and the difference key code from the fundamental-tone touch data or the difference touch data. It is possible to store the difference key code and the difference value converted into the difference touch data, which are obtained by subtracting the difference between the immediately preceding key code and the immediately preceding touch data, sequentially in the RAM 13. Then, in the playing pattern playback mode, every time a key-on event is sequentially loaded from the RAM 13, the loaded differential key code data and differential touch data are used as keys for the first key-on as reference playing information in this playback mode. The key code and the touch data of the musical sound to be generated may be obtained by adding the chord and the touch data, respectively.

In the first and second embodiments, the present invention is applied to the electronic keyboard instrument, but the invention is not limited to the electronic keyboard instrument, and a key code designating the pitch of a musical tone can be output. It is widely applicable to electronic musical instruments, for example, electronic string instruments, electronic wind instruments, electronic percussion instruments, etc., which have pitch inputting means or performance input means capable of outputting touch data for controlling the tone level of musical tones and velocity signals similar thereto. .

The information contained in the performance pattern to be recorded / reproduced includes the performance information input by the performance input means such as the keyboard 1 and the musical tones such as pitch bend and modulation shown in the first and second embodiments. It is not limited to the effect addition information relating to the effect addition to. For example, aftertouch data corresponding to the detection output from the aftertouch detection circuit 9 and foot pedal data corresponding to the output from the foot pedal 14 can be recorded / reproduced together with the time information of each event together with the data regarding various effects. , It becomes possible to play with richer performance patterns.

Further, in each of the electronic keyboard musical instruments according to the first and second embodiments, the keyboard 1, the sound source section 19, the amplifier 21, the speaker 22 and the like are integrally configured. It may be configured to be connected to each other by communication by or by audio code.

You can play with touch data of any size without changing it. Further, since the touch data included in the performance information is stored not as an absolute value but as a difference value, the memory device to be used may have a smaller storage capacity than the conventional one, and the cost can be reduced.

According to the second aspect of the invention, in the input mode for inputting performance information, the reference pitch data and touch data are first input, and thereafter the pitch data and touch data included in the performance information.

The reference touch data and the stored differential touch data are added to generate new touch data, and the performance is performed based on the generated new pitch data and touch data. Therefore, by simply changing the pitch data that is input first in playback mode, you can freely transpose the performance information that was input in advance into any range without changing the performance pattern. ,
For touch data as well, by simply changing the touch data that is input first, the performance information that has been input in advance can be played with touch data of any size without changing the overall change pattern of the touch. You can In addition, since the pitch data and the touch data included in the performance information are stored not as an absolute value but as a difference value, the memory device used may have a smaller storage capacity as compared with the conventional one, and the cost can be reduced.
