[Problems to be Solved by the Invention] In the above-mentioned conventional technology, only one note can be assigned to one performance operator, so it can only be used as a simple percussion instrument sound performance operator, which limits the performance performance. was there. On the other hand, a function that generates multiple tones by operating a single key on a keyboard is known as a single-finger function for automatic bass chord performance. However, in this case, the chord corresponding to the pressed key is fixed to have the pressed key as the root note, and it is not possible to freely assign chords to the keys. Therefore, when playing, it is necessary to accurately find and press the key of the desired chord. Moreover, these functions are usually performed in combination with automatic rhythm progression.
It was also not possible to produce sounds at the timing that the performer wanted.

In addition, in conventional devices, only sound source signals such as rhythm sounds can be assigned to performance controls such as pads, and the setting states of setting controls for setting volume and various effects cannot be assigned. could not be assigned. Therefore, these setting operators must be set to desired settings each time a performance is performed, which is troublesome.

The present invention has been made in view of the above-mentioned points, and it is possible to allocate a plurality of arbitrary sounds to a performance operator and generate the plurality of sounds in response to one operation of the operator. The aim is to provide an electronic musical instrument that can perform the following functions. Further, the present invention aims to provide an electronic musical instrument that can arbitrarily switch between producing the plurality of sounds simultaneously and producing them sequentially in response to a single operation of an operator. . Furthermore, the present invention makes it possible to assign not only the sound source signal to the performance controller, but also the setting state of the setting controller for setting the volume, various effects, etc., when operating the performance controller. The present invention aims to provide an electronic musical instrument that is capable of reproducing not only assigned sounds but also the setting states of these setting operators.

[Operation] According to the first aspect, the allocation means allows 1
A plurality of arbitrary sounds are assigned to each performance operator. Moreover, this assignment can be changed freely. The plurality of tones assigned to the performance operator are generated by the musical tone signal generating means when the performance operator is operated. Therefore, if you assign the desired multiple tones to the performance controller in accordance with the piece of music being played at each performance occasion, you only need to operate the performance controller once when you want to generate the multiple tones. You can easily generate the desired multiple sounds. In one embodiment, the assigning means assigns a plurality of tones to be generated simultaneously to one of the performance operators, and the musical tone signal generating means is configured to assign, when the performance operator is operated, Musical tone signals of a plurality of tones assigned to the performance operator are simultaneously generated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing the hardware configuration of 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 specifying the pitch of musical tones to be generated, and includes a key switch corresponding to each key of the keyboard. The panel switch circuit 15 is a circuit consisting of a group of switches corresponding to various operators for selecting, setting, and controlling tone, volume, pitch, effect, and the like. A display 16 made of an LED or the like is provided corresponding to a predetermined switch in the panel switch circuit 15, and can display the on/off status of the function corresponding to each switch.

A plurality of (for example, five) pads P0 to P4 are provided as performance operators. Each pad P0~P
4 is provided with a sensor, which detects when the pad is operated by the player's hand or the like, and provides on/off information of the pad to the bus 13. This pad P0~P4
It is preferable that the position is such that it can be easily operated by the player. For example, pads P0 to P4 may be placed near the keyboard or at an appropriate position on the front panel, or pads P0 to P4 may be separated from the main body of the electronic instrument as a separate unit so that they can be placed freely in a position that is easy for the player to operate. It may be . Any plurality of sounds can be assigned to each of the pads P0 to P4, and this assignment process is performed by the CPU 10 based on the operation of the pad and predetermined switches in the panel switch circuit 15. done under control. For convenience, this assignment processing will be referred to as pad assignment processing.

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

Furthermore, any musical tone signal generation method may be used in the musical tone signal generation circuit 17. For example, there is a method (memory read method) in which musical waveform sample value data stored in a waveform memory is sequentially read out according to address data that changes in accordance with the pitch of the musical sound to be generated, or the above address data is used as phase angle parameter data. A method (FM method) in which musical waveform sample value data is obtained by executing a predetermined frequency modulation calculation, or a method in which musical waveform sample value data is obtained by performing a predetermined amplitude modulation calculation using the address data as phase angle parameter data ( Any known method such as AM method) may be used. Further, when the memory read method is adopted, the musical sound waveform stored in the waveform memory may be only a one-cycle waveform, but it is preferable to use a multi-cycle waveform because this improves the sound quality. A method of storing a multi-period waveform in a waveform memory and reading it out is, for example, a method of storing the entire waveform from the start to the end of sound generation and reading it out once, as shown in Japanese Patent Laid-Open No. 52-121313, or Showa 58-1423
96, a method in which a multi-cycle waveform of an attack part and one or more cycle waveforms of a sustaining part is stored, and the waveform of the sustaining part is repeatedly read out after reading the waveform of the attack part once, or 60-147793, various methods are known, such as a method in which a plurality of discretely sampled waveforms are stored, the waveforms to be read are sequentially switched and specified in time, and the specified waveforms are repeatedly read out. and these may be adopted as appropriate.

Furthermore, it goes without saying that the musical tone signal generation circuit 17 may include not only the above-mentioned musical tone generation channel for generating scale tones, but also a rhythm sound source and various devices for an automatic performance function. The digital musical tone signal generated by the musical tone signal generation circuit 17 is converted into an analog musical tone signal by a digital/analog converter 18, and is spatially produced via a sound system 19. timer 2
0 generates a clock pulse of a predetermined period, and this timer clock pulse is applied to the CPU 10 and acts as a timer interrupt signal.

In this embodiment, there are two sound generation modes (referred to as pad modes) corresponding to pad operations: a simultaneous sound mode and a sequence sound mode. First, the first mode, ``simultaneous sound mode'', is a mode in which multiple sounds are simultaneously sounded in response to the operation of one pad. The second mode, the "sequence sound generation mode", is a mode in which multiple sounds are produced in sequence in response to the operation of one pad. Some mode selection means is provided for selection of pad modes. In the above-described pad assignment processing, selection (mode selection) is made as to which pad mode is used to generate sound for a desired pad, and assignment processing is performed in accordance with the selected mode. In this case, the generation time intervals of the sequence sounds in the "sequence sound generation mode" can be set arbitrarily at the time of allocation. For example, a method may be adopted as appropriate, such as selecting and/or specifying sounds to be sequentially produced at desired time intervals, and storing the time interval information together with information on the selected sounds.

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

FIGS. 2a, 2b, and 2c show examples of the format of the pad memory in the data and working RAM 12. In FIG. First, areas of pad memories PDM0 to PDM4 are prepared for each pad P0 to P4 (
(see Figure 2a). The storage format in each pad memory PDM0-PDM4 differs depending on the currently selected pad mode corresponding to each pad. FIG. 2b shows an example of the storage format in one pad memory PDM in the simultaneous sound generation mode. FIG. 2c shows an example of the storage format in one pad memory PDM in the sequence sound generation mode.

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

P (PN): Pointer: This pointer is not used in the simultaneous sound mode, and will be described later. PAT (PN): Pad assigned sound data: Data of multiple sounds assigned to the pad corresponding to this pad number PN by pad assignment processing, 1 note per note.
Use byte area. In this example, since a maximum of five tones can be produced simultaneously, five bytes are used to store this pad assignment sound data. The 1-byte data that makes up the data for one note consists of a multi-bit key code that indicates the pitch (key) of the assigned note,
It consists of a 1-bit flag to indicate that it has been allocated. TGCHF: Tone source channel flag: A flag indicating to which tone generation channel each tone indicated by the above-mentioned assigned tone data is assigned. In the pad assignment process, it is not specified which musical sound generation channel is used to produce each assigned note. Assignment to musical tone generation channels is performed by key assignment processing. This sound source channel flag stores which channel is assigned by key assignment processing. This sound source channel flag consists of 2 bytes = 16 bits, 1 bit corresponds to 1 channel, and the bit corresponding to the channel to which the pad assigned sound is assigned is set to “
1” stands.

Referring to FIG. 2c, the stored data in the sequence sound generation mode will be explained as follows. PM (PN): Pad mode data: As described above. PTC (PN): Pad tone data: As described above. P (PN): Pointer: This is a pointer that indicates the order of events, which will be described later, in order to control the generation of sequence sounds in order. Sequence data area: This is an area that stores the sequence sound data assigned to the pad corresponding to this pad number PN by pad assignment processing in the order of events (order of sound generation timing), and 2-byte area is used for each event. , a total of 20 events = 40 bytes of storage area. 2 bytes of data per event is
It consists of event data E (PN, p) and duration data D (PN, p). p=0,1,2,...,1
9 is an event ranking, which is designated by the pointer P (PN). The 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" at a key-on event and "0" at a key-off event. Duration data D (PN, p) is data indicating the time interval from the event to the next event. Note that 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 processing executed by the microcomputer will be explained with reference to flowcharts shown in FIGS. 3 to 12. FIG. 3 shows an example of a main routine. After performing a predetermined initial setting process, "key processing", "pad processing", "panel switch processing",
Repeat the "other processing" routine. In "key processing", each key switch in the keyboard circuit 14 is scanned to detect whether it is on or off, and in the case of a key-on event, key-on event processing is performed, an example of which is shown in FIG. 4, and in the case of a key-off event, processing is performed as shown in FIG. Key-off event processing is performed as an example. In "pad processing", each sensor of pads P0 to P4 is scanned to detect whether it is on or off, and in the case of a pad-on event, pad-on event processing, an example of which is shown in Figure 6, is performed, and in the case of a pad-off event, pad-on event processing 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 whether they are on or off, and various processing is performed based on the detection. An example of the processing executed in this "panel switch processing" is shown in FIG.
It is shown in FIGS. 9 and 10. "Other processing" performs various other processing. One of the processes performed here is sequence control processing as shown in FIG.

During execution of the main routine, a clock pulse from timer 20 periodically interrupts the main routine. In that case, the timer interrupt process shown in FIG. 12 is performed. Here, the contents of the timer register TIME are incremented by one. Therefore, timer TIME is free-running and its overflow is ignored. In addition, in the initial setting process, each pad memory PDM0 to PDM4
Predetermined initial data may be preset. In this way, when the power is turned on, a predetermined plurality of tones can be initially assigned to each pad P0 to P4. Of course, such initial allocation may not be necessary.

--Selection of pad mode--The pad mode is selected when the panel switch circuit 15 is selected during pad assignment processing.
The selection can be made by operating the pad assign switch PASW located at . Specifically, in this embodiment, a pad assign mode is determined according to the operation of the pad assign switch PASW, and a pad mode is determined according to this pad assign mode. To explain the pad assign mode, there are four modes 0 to 3. These four pad assignment modes are instructed as follows by the contents of register PAM.

PAM=0: Play mode: Indicates a mode for normal performance, that is, no pad assignment processing. PAM=1: Multiple note assignment mode: Mode for assigning arbitrary multiple notes to be sounded simultaneously to one desired pad. When this mode is selected, the simultaneous sound mode is selected as the pad mode. In the embodiment, this mode is selected by operating the pad assign switch PASW before operating a desired pad. PAM=2: Sequence sound assignment preparation mode: A mode indicating the initial state (preparation state) when assigning arbitrary plural sounds to be produced in sequence to one desired pad. When this mode is selected, the sequence sound generation mode is selected as the pad mode. In the example,
This mode is selected by operating the pad assign switch PASW while operating a desired pad. PAM=3: Sequence sound assignment storage mode: A mode that indicates that a storage operation has been entered during sequence sound assignment. In the embodiment, the sequence sound assignment preparation mode (P
When an assigned tone 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 assignment mode PAM are checked, and if PAM=0, the process goes to step 31, and any pad switch P0 is selected.
~Check whether P4 is turned on at the same time. If NO, it means that the pad assign switch PASW was pressed before the pad switches P0 to P4, and the process goes to step 32, where the pad assign mode PAM is set to 1. In this way, the multiple note assignment mode is selected. If step 31 is YES, go to step 33,
The pad number of the pad that is already turned on is set in register i. Next, go to step 34 and set the pad assignment mode PAM 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 completed, but this point will be described later. As shown in FIG. 13, a display such as an LED is provided beside the pad assign switch PASW to provide a display according to the state of the pad assign mode PAM. For example, by controlling the light to turn off when PAM=0 and turn on when PAM≠0, it is possible to display that the pad assignment process is in progress.

--Assignment of multiple notes--As mentioned above, P
Setting AM=1 selects multiple note assignment mode. In this state, turn on the desired pad (any one of P0 to P4) to which you wish to assign. Then, the pad-on event process shown in FIG. 6 starts, the following process is performed, and the sound currently assigned to the pad is produced. First, the pad number of the turned-on pad is stored in register PN (step 35). next,
It is checked whether the pad assignment mode PAM is 2 or 3 (step 36). Since PAM=1 now, the answer is NO, and the process goes to step 37, where the pad number of register PN is stored in register i. Next, pad memory PDM (PDM0 to PD
Pad mode data PM (PN) from one of M4)
is read and checked to see if it is "0" (step 38). If it is “0”, it is simultaneous sound mode,
Through the processing of steps 39 and 40, the pad memory PD
Pad assigned sound data PAT(PN) is read from M, a plurality of tones corresponding to this pad assigned sound data are assigned to different channels, and the musical tone signal generation circuit 17 generates these plural tones. On the other hand, “0
”, it is the sequence sound mode, and the process of steps 41 to 47 and FIG.
Read out the event data and duration data of each sequence sound sequentially from the sequence data area of the DM,
Each tone is assigned to an appropriate channel, and the tone signal generating circuit 17 generates these tones. Note that details of the sound generation control in the simultaneous sound generation mode and the sequence sound generation mode will be described later.

[0028] In this way, the operator can confirm with his ears the sound already assigned to the pad. Then, while keeping the pad on, press the desired key to be newly assigned. Then, the key-on event processing shown in FIG. 4 starts, and the following processing is performed. First, enter the key code of the newly pressed key in register K.
Register it on the CD (step 48). Next, check whether the tone code TC of the currently selected tone is "&HFF", which indicates keyboard percussion (step 4).
9). Note that keyboard percussion refers to the use of keys on the keyboard as percussion instrument sound designators; in this case, the tone code TC is set to a predetermined value "&HFF", and the tone name, that is, the percussion instrument tone name, is specified by the key code. Ru.

If the pressed key is a normal scale note specified key, the process goes to step 50, where normal sound generation processing (including key assignment processing for assigning sound generation to any of the 16 channels) is performed, and the pitch of the pressed key is generates a musical tone signal with If the pressed key is a designated key for keyboard percussion, the process goes to step 51 and predetermined sound generation processing for keyboard percussion is performed. In the next step 52,
For the channels used in the above sound generation process, the tone source channel flag TGCHF of the corresponding channel in all pad memories PDM0 to PDM4 is turned off. This is because if the channel has already been used by a pad, that use is canceled and priority is given to the latest event, which is the sound of the currently pressed key. In the next step 53, the contents of the pad assignment mode PAM are checked, and PAM=
If it is 0 or 1, this process ends.

[0030] In this way, when one or more desired keys to be assigned to a pad are pressed, the above processing is performed for each pressed key. If you do not want to assign the pressed key to the pad, you can release the key. Finally, with one or more desired keys pressed, the pad that had been kept on until then is turned off. Then, the pad-off event process shown in FIG. 7 starts, and the following process is performed, and a musical tone corresponding to one or more keys being pressed is assigned to the pad. First, the pad number of the pad that has been turned off is stored in register PN (step 54). next,
Pad memory PD corresponding to the pad number of register PN
M(one of PDM0 to PDM4, this is PDM(PDM)
The pad mode data PM(PN) is read from the pad mode data PM(PN) (denoted as N), and it is checked whether PM(PN)="0" (step 55). If YES, go to step 550, read pad tone data PTC(PN) from the pad memory PDM(PN), and set PTC(PN)≠&HFF.
Find out if it is. If YES, the process goes to step 56, where the musical tone signal generation circuit 17 (denoted as TG in the flow diagram) corresponds to the channel (denoted as CH in the flow diagram) for which the tone source channel flag TGCHF in the pad memory PDM (PN) is on. ) sends a key-off signal. This is to cancel the sound generation assignment, since the sound previously assigned to the pad was being produced. In step 57, all tone source channel flags TGCHF in the pad memory PDM (PN) related to the off-pad are turned off.

Even if PM(PN)="0", that is, the simultaneous sound mode, if the sound is a keyboard percussion sound, the answer at step 550 is NO, and the process goes to step 57 without performing step 56. This is because keyboard percussion sounds are muted without any particular key-off signal being given. Also, if the previously assigned sound for the pad is a sequence sound, the PM
(PN)=“1”, step 55 is NO,
Go to step 58 without performing steps 56 and 57. This is because in the case of sequence sounds, muting processing is performed based on event data.

In the next step 58, PAM=1 and P
Check whether N=i. In the current example, since it is a multiple note assignment mode, the pad assignment mode PAM=
It is 1. Register i stores the pad number related to the latest pad-on event (step 37 in FIG. 6), and register PN stores the pad number related to the current pad-off event. Usually PN
=i, step 58 becomes YES, step 5
Go to 9. In step 59, it is checked whether there is a currently pressed key. If there is a pressed key, step 60~
62, the allocation data is written to the pad memory PDM (any one of PDM0 to PDM4) corresponding to the pad number specified by register i. That is, the pad memory PD corresponding to pad number i
The pad mode data PM(i) for M is set to "0", and it is stored that the simultaneous sound mode has been selected for this pad (step 60). Then, a tone code TC indicating the currently selected tone is stored as pad tone color data PTC(i) in the pad memory PDM corresponding to the pad number i (step 60). Also, the key code of the currently pressed key is written as pad assigned sound data PAT (PN) in the pad memory PDM corresponding to pad number i (step 61).
. In this case, key codes of up to five tones can be written, and when the number of keys pressed simultaneously is six or more, only five keys are selected according to predetermined priority selection criteria and the key codes are written. The priority selection criteria may be determined as appropriate, such as prioritizing high tones, prioritizing low tones, or prioritizing keys pressed at the latest time. Furthermore, an on flag "1" indicating assignment is set corresponding to the written key code. When the number of keys pressed simultaneously is less than five, data "&H00" indicating no key code and an off flag "0" are stored in the remaining area where no key code is stored (step 62).

[0033] As described above, when one or more desired keys to be assigned to the pad that has been turned on is pressed and the pad that has been turned on is turned off, the keys corresponding to the one or more keys are pressed. Sound information is stored in a pad memory PDM corresponding to the pad. In this way, the desired one or more tones are assigned to the pad. In addition, if you turn on a certain pad to make the sound assigned to it sound, and after confirming it, if you do not intend to change the assignment, press the key to select the new assigned sound. Turn off the pad instead. In that case, step 59 will be NO, so steps 60 to 62
Terminates processing without performing any processing. Furthermore, if a certain first pad is turned on, and before turning it off, another second pad is turned on, and then the first pad is turned off, PN=i in step 58 does not hold. Step 60~
62 processing is not performed. When the second pad is turned off, PN=i in step 58 is established, and steps 60 to 6
Process 2 is performed.

Note that the tone color of the assigned tone can also be freely selected. In this example, when assigning scale notes to pads, the number of tones that can be assigned to each pad is 1.
There are only types. In that case, the desired tone to be assigned is selected in advance using the panel switch circuit 15. When the timbre switch of a desired timbre is turned on, the timbre switch-on event process shown in FIG. 10 is performed, and the timbre code TC corresponding to the turned-on timbre switch is registered as information on the selected timbre. By storing this tone color code TC as 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 the plurality of tones assigned to one pad is common, but as a modification, it is of course possible to assign a different tone to each tone.

It is also possible to assign keyboard percussion sounds to pads. To do this, set the keyboard percussion mode in advance. The keyboard percussion mode is controlled by the keyboard percussion switch KPSW provided in the panel switch circuit 15.
It is turned on and off depending on the operation. When the keyboard percussion switch KPSW is turned on, the keyboard percussion switch on event process shown in FIG. 9 is performed. First, it is checked whether the tone color code TC is a predetermined value "&HFF" indicating the keyboard percussion mode (step 63). If the keyboard percussion mode is not yet activated, branch to NO, save the current tone code TC in the buffer TCBUF (step 64), and change the tone code TC to the code “&HFF” indicating the keyboard percussion mode. do(
Step 65). After changing to the keyboard percussion mode, turn on the desired pad and press the key corresponding to the desired keyboard percussion sound. As described above, when the pad is turned off, the key code of the pressed key is stored in the pad memory PDM along with the tone code TC indicating the keyboard percussion mode. If you want to exit keyboard percussion mode, press the keyboard percussion switch KPSW again.
Turn on once. Then, step 63 branches to YES, and the timbre code stored in the buffer TCBUF is re-registered as timbre code TC (step 66). Incidentally, as shown in FIG. 13, a display such as an LED is provided beside the keyboard percussion switch KPSW to provide a display according to the state of the keyboard percussion switch mode. For example, when keyboard percussion mode is selected (TC=&
When HFF) lights up, when not selected (TC≠&
(when HFF) is controlled so that the light is turned off. To exit the multiple note 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 (multi-note assignment mode), and the process proceeds to step 67, where the contents of pad assignment mode PAM are reset to PAM=0 (play mode).

--Assignment of sequence sounds--If you want to assign sequence sounds as described above, first,
Turn on a desired pad (any one of P0 to P4) first. Then, the pad on event process shown in FIG. 6 starts, and since PAM is not 2 or 3 at this time, step 36 branches to NO, and the same process as described above is performed, and the sound currently assigned to the pad is is pronounced. After confirming the already assigned sounds, if you want to assign a new sequence sound to this pad, turn on the pad assign switch PASW. Then, step 31 in FIG. 8 branches to YES, the pad number of the turned-on pad is stored in register i, PAM=2 is set, and the sequence sound assignment preparation mode is entered. After setting PAM=2, the pad may be turned off at any time. Sequence tones are assigned/stored not at pad off timing, but at each key press/key release event.

After setting PAM=2, the operator sequentially presses desired plurality of keys at a desired timing to designate plurality of tones to be assigned as sequence tones. in this case,
There is no problem even if two or more keys are pressed redundantly during a certain period. In response to this series of key operations, the key-on event process shown in FIG. 4 is performed when the key is pressed, and the key-off event process shown in FIG. 5 is performed when the key is released. Then, for each event, the pad memory PD is
At M, sequence data is stored and sequence sounds are assigned. When a key is pressed, the key code of the pressed key is registered in the register KCD and the corresponding musical tone is generated by the processing of steps 48 to 52 in FIG. When the first key is pressed, PAM=2 is still present, so in step 53 it is determined that PAM=2, and the process goes to step 68. In step 68, the pad assignment mode is set to PAM=3 to enter the sequence sound assignment storage mode. Next, pad mode data PM(i) in the pad memory PDM (one of PDM0 to PDM4) corresponding to the pad number of register i is set to "1", and the sequence sound mode is selected corresponding to this pad. It memorizes what has been done (step 69). Then, a tone code TC indicating the currently selected tone is stored as pad tone data PTC(i) in the pad memory PDM corresponding to the pad number i (step 69).
.

Next, a predetermined one-bar 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 because, for example, one phrase of the sequence sound is limited 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 allocated is set to an initial value of 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, pointer P
)=0, the first event data E(i
, 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 (step 72). Then, the current value of the timer TIME is stored in the old time register OLDT.
, thereby storing the current event occurrence time (step 73).

When the second and subsequent keys are pressed, PAM=3 has already been reached, so in step 53 the PA
It is determined that M=3 and the process goes 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 pad number i, the duration register is stored as duration data D(i, P(i)) of the event order specified by 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 order. Next, the pointer P(i) is incremented by 1 and the next event ranking (that is, the current event ranking) is designated (step 76).

In the next step 77, event data E(i,
As P(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 pointer P(i) has reached the maximum value of 19. If NO, the process goes to step 79, and the current value of the timer TIME is set in the old time register OLDT. In this way, in response to a new key-on event, duration data D(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 shown in FIG. 5 starts. First, the key code of the currently released key is registered in the register KCD (step 80). Next, the tone code TC of the currently selected tone is the value “&HFF” indicating keyboard percussion.
” (step 81). If the released key is a normal scale note specified key, step 81 returns NO.
Then, the process goes to step 82 and normal muting processing is performed. For example, as is well known, a key-off signal is sent corresponding to the channel to which the released key is assigned, and the volume envelope of that channel is switched to attenuation mode, thereby attenuating the sound of the musical tone signal related to the key release. to erase. In the next step 83, it is checked whether the pad assignment mode is PAM=3. In the case of the present example, since PAM=3 has already been set, the answer is YES and the process goes to step 84.

The processing in steps 84-89 is almost the same as the processing in steps 74-79 in FIG. The difference is that in step 87, the key code of the register KCD (that is, the key code of the key related to the current off event) is used as the event data E(i, P(i)) of the event order specified by the pointer P(i). ) and an off event flag "0" are stored. In this way, even in response to a key-off event, duration data D(i, P(i)) related to the previous event order and event data E(i, P(i) related to the current event order)
)+1) is written. If the released key is a keyboard percussion designated key, step 81 is YES.
Then, this key-off event processing is ended without performing any further processing. This is because the percussion sound attenuates regardless of the key release operation, so no special muting process is required.

When the value of pointer P(i) reaches the maximum value 19 due to the increment in step 86,
Step 88 becomes YES, and the process goes to step 90. Here, the pad assignment mode is set to PAM=0, that is, play mode (step 90), and the event order is 19.
A predetermined end mark code is written at the position of duration data D (i, 19) (step 91). Then, the value of pointer P(i) is set to "&HFF". This completes the pad assignment process. When processing a key-on event, the value of pointer P(i) is the maximum value 19
4, step 78 in FIG.
becomes YES, and steps 93 to 95, which are exactly the same as steps 90 to 92 described above, are performed, and the pad assignment process ends.

On the other hand, each time the main routine goes through the
1 sequence control processing is performed. Here, first,
Pad assignment mode is checked (step 96)
). As described above, when the sequence sound assignment storage mode is being executed, PAM=3, and the process goes to step 97.
It is checked whether the current value of the timer TIME matches or exceeds the value of the sequence end time register ENDT. If NO, end this routine, but
If YES, steps 98-100 are executed. The processing in steps 98 to 100 is performed in step 9 of FIG.
This process is exactly the same as steps 0 to 92, and this ends the sequence sound allocation process. Also, while the sequence sound assignment storage mode is in progress, the pad assign switch PA
The sequence sound assignment process can also be ended by turning on the SW again. In that case,
In step 30 of FIG. 8, it is determined that PAM=3, and the processes of steps 101 to 103 are executed. Step 10
Processes 1 to 103 are completely similar to steps 90 to 92 in FIG. 5 described above. Note that if another pad is turned on while sequence sound assignment processing is being performed for a certain pad, the pad assignment mode PAM is 2 or 3, so when that other pad is turned on, In the key-on event processing shown in FIG. 6, which is executed in step 36, the result is YES, and the process returns to the main routine without performing the key-on event processing.

--Simultaneous sound generation of multiple sounds--By turning on a desired pad, multiple sounds assigned to that pad can be produced. When a pad is turned on, the pad on event processing shown in FIG. 6 starts as described above, reads the pad mode data PM (PN) from the pad memory PDM (PN) corresponding to the pad, and determines that it is "0". Check whether there is one (step 38). If the pad mode selected corresponding to the pad is the simultaneous sound mode, PM(PN)="0", and step 39
40 processes are performed. In step 39, one or more key codes assigned to the turned-on pad are read from the pad assigned sound data PAT(PN) area of the pad memory PDM(PN) corresponding to the pad that has been turned on;
Assign them to different channels. These key codes are assigned and corresponding to the channels, the key codes and key-on signals are sent to the musical tone signal generation circuit 17. In addition, the pad memory PDM (PN)
The pad tone color data PTC (PN) is read from the pad tone color data PTC (PN) and is also sent to the musical tone signal generation circuit 17. In the corresponding channels in the musical tone signal generation circuit 17, these 1
Musical tone signals corresponding to a plurality of key codes are formed and generated using tones corresponding to the tone color data.

[0046] Thus, by one pad operation, one or more tones assigned to the turned-on pad are simultaneously sounded. For example, if a desired chord is assigned to the pad, the chord can be easily played by operating the pad once. Moreover, since the pad assignments can be changed as appropriate depending on the purpose of the performance, a limited number of pads can be used efficiently as performance controls for various chords or arbitrary multiple notes. Easy to operate. In step 40, corresponding to the channel assigned in the previous step, the pad memory PD is
Set the sound source channel flag TGCHF in M(PN) to "1".

When the pad that was turned on is turned off, the pad off event processing shown in FIG. 7 starts as described above, and the pad mode data PM (PN) and pad tone data PTC of the pad related to the current off event are (PN) is PM(PN)=“0” and PTC(PN)≠&HFF
(steps 55 and 550). If it is simultaneous sound mode and normal tone, go to step 56,
The channel to which one or more sounds assigned to the pad is assigned (sound source channel flag TG)
A key-off signal is sent to the channel on which CHF is on. As a result, the sound generated by the channel is put into an attenuated sounding state after the key is released, and one or more sounds corresponding to the pad are muted. After that, the process goes to step 57, and all tone source 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, the answer to step 550 is NO, and the process proceeds to step 57 without performing step 56. This is because the processing of step 56 is unnecessary because the keyboard percussion sound is attenuated without any special key-off processing. Note that keyboard percussion sounds may be generated by a dedicated percussion sound generation channel or device without being assigned to the 16 channels that generate scale sounds.

--Generation of sequence sound-- When a desired pad is turned on, the pad on event processing shown in FIG. 6 starts as described above, and pad mode data PM (PN ) and check whether it is “0” (step 3
8). If the pad mode selected corresponding to the pad is the sequence sound generation mode, PM(PN)="1", and the process proceeds to step 41, where sequence sound generation processing is started. In step 41, the pointer P(PN) in the pad memory PDM(PN) of the turned-on pad is
is set to 0 to indicate the initial event order. Next, event data E(
PN, 0) and duration data D (PN, 0) are read out, and a sound corresponding to the key code indicated by the event data E (PN, 0) is produced (step 42). This sound generation process is almost the same as the process in steps 39 and 40 described above, and the event data E (PN
, 0) is assigned to one of the channels, and the key code, key-on signal, and pad tone data PTC (PN) are sent to the channel of the musical tone signal generation circuit 17, thereby generating the musical tone. In the channel of the signal generation circuit 17, one musical tone signal corresponding to the key code is formed with a tone color corresponding to the tone color data, and is generated. Also, the tone source 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, the process goes to step 44, and the current value of the timer TIME is set to the corresponding duration data D (PN,
0) and stores the addition result 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. Then pointer P(PN
) is increased by 1 (step 45). If the read duration data D (PN, 0) is an end mark code, the process goes to step 46 and a predetermined sequence end process is performed. Here, the processing necessary to end the generation of the sequence tones, for example, if a key-off signal has not been issued yet, a key-off signal is given to the musical tone signal generation circuit 17, and the pad memory PDM corresponding to the pad number PN is Sound source channel flag T in (PN)
Perform processing such as turning off all GCHF. and,
The value of pointer P (PN) is set to a predetermined end value &HFF, and the process ends (step 47). As described above, in the case of a pad-on event, processing is performed to generate the sequence sound of the first event order assigned to the pad. Processing of the second and subsequent events is performed in the sequence control process shown in FIG. This sequence control process is repeated every time the main routine is repeated.

Since PAM=0 or PAM=1 in the play mode or the multiple note assignment mode, the process branches from step 96 to step 104 in FIG. In step 104, the pad number register PN is preset to 0. Next, in step 105, pad mode data PM (PN) and pointer P (PN) are read from pad memory PDM (PN) specified by PN, and
Check whether PN)=“1” and P(PN)≠&HFF. If the sound generation mode assigned to this pad number PN is not the sequence sound mode, or if the pointer P (PN) is set to the predetermined end value &HFF even if it is the sequence sound mode, step 106
, and check whether the pad number PN has reached the maximum value of 4. If the pad number PN has not yet been reached, the process goes to step 107 and the pad number PN is incremented by one. Then return to step 105,
The above determination is made regarding the pad number PN incremented by 1.

The sound generation mode assigned to this pad number PN is the sequence sound mode, and the pointer P
If (PN) is not yet set to the predetermined end value &HFF, step 105 is YES and step 1
08 and register NEXT(
PN), and extracts the next event time data from timer T.
Compare with the current value of IME. When the current value of the timer TIME matches or exceeds the next event time NEXT (PN), the process goes to step 109, but the current value of the timer TIME still exceeds the next event time NEXT (PN).
If it has not yet reached step 106, the loop of steps 106, 107, and 105 described above is repeated. When the above-mentioned check is completed for all five pad numbers, PN=4 becomes YES, and this sequence control process ends.

As this sequence control process is repeated several times, the current value of the timer TIME reaches 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) indicated by N is read, and the current value of the pointer P (PN) of the pad memory PDM (PN) is
Event data E (PN, P (PN)) of the event order indicated by the pointer P (PN) and duration data D (PN, P (PN)) from the sequence data area of DM (PN) (see c in Figure 2) )), and performs sound generation processing or muting processing of the sound corresponding to the key code indicated by the event data E (PN, P (PN)). If the flag of the event data E (PN, P (PN)) is an on flag indicating a key press, a sound generation process is performed, and if it is an off flag indicating a key release, a mute process is performed. This pronunciation process is almost the same as the process in step 42 described above,
The key code indicated by the event data E (PN, P (PN)) is assigned to one of the channels, and the key code, key-on signal, and pad tone data PTC (PN ), thereby forming and generating one musical tone signal corresponding to the key code in the channel of the musical tone signal generation circuit 17 using a tone color corresponding to the tone color data. Also, the tone source channel flag TGCHF corresponding to the assigned channel is turned on. In the muting process, a key-off signal is sent to the musical tone signal generation circuit 17 in correspondence with the channel to which the key code related 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 source channel flag TGCHF for the channel that sent the key-off signal.

In this manner, in the case of an off-event, muting processing is performed in step 109, and the sequence sound related to the off-event that had been generated up to that point is muted. Also,
In the case of an on event, sound generation processing is performed in step 109, and a new sequence sound is produced. Step 110
Now, the read duration data D(PN, P(
Check whether PN)) is an end mark code. NO
If so, go to step 111, add the duration data D (PN, P (PN)) to the current value of the timer TIME, and write the addition result to the next event time register NEXT (PN) corresponding to the pad number PN. Store. Thereafter, the value of pointer P (PN) indicated by PN is increased by 1 (step 112). If the read duration data D (PN, P (PN)) is an end mark code, the process goes to steps 113 to 114, where a predetermined sequence end process and pointer processing similar to steps 46 and 47 (FIG. 6) described above are performed. Perform reset processing. As described above, a plurality of sounds assigned as sequence sounds are sequentially sounded according to the event data and duration data stored in the sequence data area.

--Second Embodiment-- In the above embodiment, the performance operators, that is, the pads P0 to P4
Only sound source signals such as scale tones and rhythm tones can be assigned to the timbres, and only tone switch setting information can be assigned to the setting operators at the same time. next,
As a second embodiment, setting states of not only tone setting operators but also various setting operators for setting volume, various effects, etc. can be assigned corresponding to arbitrary performance operators, that is, pads P0 to P4. An example in which this is possible will be described. The hardware configuration diagram of the electronic musical instrument according to the second embodiment may be considered to be as shown in FIG. 1, similar to the first embodiment. Further, the details generally follow the examples shown in FIGS. 2 to 13, but some points are changed as described below. In the following, changes will be explained, and points that are not explained can be considered to be the same as in the first embodiment unless any particular inconvenience occurs.

These setting operators are provided in the panel switch circuit 15. An embodiment of a portion 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 addition of an auto-harmony effect. The auto-harmony effect is one in which a harmony effect is obtained by automatically adding an auto-harmony sound, that is, an automatic performance sound, to the sound being played.

To explain the auto-harmony effect in a little more detail, for example, a chord played on a keyboard or the like is detected, and a note to be added is determined according to the type of the chord and auto-harmony type designation data specified separately. Examples of auto-harmony types include duet, trio, octave, and strum. Duet is an effect that automatically adds one sound that is lower (or higher) by a predetermined pitch to the main performance sound (for example, melody sound) to be added. Trio is an effect that automatically adds two different sounds that are lower (or higher) by a predetermined pitch to the main performance sound (for example, a melody sound) to be added. The octave is 1 octave for the main performance sound (for example, melody sound)
This is an effect that automatically adds an octave lower (or higher) sound. Strum is an effect that automatically adds a plurality of different arpeggic sounds that are lower (or higher) by a predetermined pitch to the main performance sound (for example, a melody sound) to be added. There is not just one type of duet, trio, octave, strum, etc.
There may be multiple types depending on the pitch and pattern of the added sound. The type of chord to be played determines the pitch of the automatic tone to be added. The main performance sound to be added is, for example, a melody sound, and this is, for example, the highest pressed key on the melody performance keyboard or keyboard range. Alternatively, when a sound assigned to a pad is to be produced, these autoharmonic sounds may be added to the sound assigned to the pad. Alternatively, it may be automatically determined whether the currently generated sound is a pad-assigned sound, and the autoharmony sound may be added only to the pad-assigned sound.

Returning to FIG. 14, the auto-harmony type setting switch AHTP is a switch for setting the above-mentioned auto-harmony type, and includes, for example, an increment switch and a decrement switch. In response to pressing the increment switch or decrement switch of the type setting switch AHTP, the numerical data displayed on the data display DPY increases or decreases, allowing a desired autoharmony type to be selected. In addition, similar to the aforementioned pad assign switch PASW and keyboard percussion switch KPSW, a light emitting diode LED is provided corresponding to the automatic accompaniment switch AASW and auto harmony switch AHSW, respectively, so that the automatic accompaniment and auto harmony effects can be turned on. It lights up when. The volume switch VOLM is a switch for setting the volume level of musical tones, and includes, for example, an increment switch and a decrement switch. Numerical data displayed on the data display DPY increases or decreases in response to a pressing operation of the increment switch or decrement switch of the volume switch VOLM, and a 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 AHTP will be explained.
An example will be described in which the autoharmony setting information set by . First, in this second embodiment, data and working RA
The storage data format of the pad memory in M12 is:
It is as shown in FIG. FIG. 15 corresponds to FIG. 2, and a
is the same as in FIG. 2, but b and c are each changed. In other words, the pad memory (
The storage data format of PDM) is as shown in Fig. 15b, and compared to the case of Fig. 2b, the volume setting data V
A storage section is added that stores OL (PN) and auto-harmony data AH (PN) as header data (setting data common to the sounds assigned to the pad). The volume setting data VOL(PN) is volume information set by the volume switch VOLM corresponding to the pad with this pad number PN. Auto harmony data AH (PN)
is the auto harmony switch AHSW and type setting switch AHT corresponding to the pad with this pad number PN.
This is auto-harmony setting information (auto-harmony on/off setting data, auto-harmony type setting data) set by P.

An example of the storage data format of the pad memory (PDM) in the sequence sound mode is as shown in c in FIG. A storage section is added that stores the auto-harmony data AH (PN) and auto-harmony data AH (PN) as header data. In addition, these tone, volume, and auto-harmony setting information are stored in event data E (PN,
p) in the sequence data area. That is, in this example, not only key-on and key-off, but also changes in the tone switch, volume switch VOLM, auto harmony switch AHSW, and type setting switch AHTP in the panel switch circuit 15 are detected as events for sequence sound generation control, and the sequence It is stored in the data area. Therefore, in the format of c in FIG. 15, the event data E(PN,p) consists 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, volume, auto-harmony on/off, auto-harmony type, etc. The event data content is data indicating 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.

[0060] When a sequence sound is generated, the sequence sound is initially set using the tone, volume, and auto-harmony setting information PTC (PN) and VO stored as header data.
It is controlled according to L (PN), AH (PN), but as time passes, event data E (PN, p) is read out, and the event data is updated according to changes in settings such as tone, volume, auto harmony, etc. If the corresponding information is included, control is performed to change the setting state of the tone color and volume of the subsequent sequence sound, or the setting state of the autoharmony effect etc. added to the sequence sound.

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

--Processing in multiple tone assignment mode--
- In this case, the pad-off event process in FIG. 7 is changed as shown in FIG. 19 as the process related to the multiple note assignment mode. In FIG. 19, step 60 is followed by step 601.
This process differs from FIG. 7 in that . First, as mentioned above, operate the pad assign switch PASW to enter the pad assign mode
Set AM to 1. Also, at an appropriate time, select a desired tone using the panel switch circuit 15, set the volume to a desired value using the volume switch VOLM, and set the desired tone for automatic accompaniment and auto harmony using the switches AASW, AHSW, and AHTP. Make selections/settings. The selection/setting states of these setting operators are detected and scanned in the panel switch processing of the main routine, and are stored in appropriate buffer registers. Then, in the same way as above, turn on the desired pad you want to assign,
Press one or more desired keys to be assigned to that pad, and then turn off the pad that was on.

Then, in the process of FIG.
If the answer is YES in step 8, the process goes to step 59, and after confirming that there is a key being pressed, steps 60 to 62 are performed. As described above, in this process, data is written to the pad memory PDM corresponding to the pad that has been turned off (pad number PN=i). That is, in step 60,
The pad mode data PM(i) is set to "0" to register the simultaneous sound generation mode, and the timbre code TC of the timbre set by the timbre switch is registered as the pad timbre data PTC(i). Next step 601
Now, 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 registered. The off setting information and the auto-harmony type setting information set by the type setting switch AHTP are registered as auto-harmony data AH(i) corresponding to the pad (pad number PN=i). Thereafter, steps 61 and 62 similar to those described above are performed. In this way, the volume and autoharmony setting information are registered as header data in the format shown in FIG. 15b.

--Processing when assigning sequence sounds-- In the second embodiment, the key-on event processing in FIG. 4 is changed as shown in FIG. 17 as processing related to assigning sequence sounds. 17 differs from FIG. 4 in that step 691 is inserted after step 69, and the rest is the same as the process in FIG. 4. However, in the normal sound generation process at step 50, the volume data buffer VO, which will be described later,
The volume of the generated sound is controlled according to the LBUF data. The process in step 691 is similar to step 601 in FIG. 19 described above.
This is the same process as . By adding the process of step 691, similarly to 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 is stored in the format shown in c in FIG. VOL(i) and autoharmony data AH(i) are registered as header data. That is, the volume and auto-harmony data that should be set as header data are set in advance to a desired state using the volume switch VOLM and the switches AHSW and AHTP. Then, as described above, set the pad assign mode to PAM=2 and press the first key of the sequence sound. Then, step 5 in Figure 17
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 autoharmony data AH(i) are registered as header data.

When assigning sequence sounds, in order to store setting data such as timbre, volume, auto-harmony, etc. in the pad memory PDM as event data in response to time changes, similar to key-on and key-off data, the process shown in FIG. Performs setting operator event processing as shown in . Selection by tone switch, volume switch VOLM, auto harmony switch AHSW, auto harmony type setting switch AHTP, etc.
When the setting state is changed, the event processing shown in FIG. 21 starts. In FIG. 21, in step 120, the pad assignment mode PAM is checked. PAM is 0,1
, 2, this event processing ends immediately. P.A.
When M=3, that is, in the sequence sound assignment storage mode, steps 121 to 129 are performed. The processing in steps 121 to 129 is performed in steps 74 to 7 in FIG.
This process is similar to the process in Nos. 9, 93-95. That is, in step 121, 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, pad memory P corresponding to pad number i
In the sequence data area in the DM (see c in FIG. 15), the time interval data stored in the duration register D is used as the duration data D(i, P(i)) of the event order specified by the pointer P(i). Store (step 122). For example, 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 order. Next, pointer P(i)
is incremented by 1, and the next event ranking (that is, the current event ranking) is specified (step 123).

In the next step 124, pointer P(i) is set in the sequence data area (see c in FIG. 15) in the pad memory PDM corresponding to pad number i.
Event data E (of the event order specified by
As i, P(i)), an event code indicating the type of the current setting operator event and event content data indicating its setting state are written. In the next step 125, it is checked whether the value of pointer P(i) has reached the maximum value 19. If NO, go to step 126 and set timer TIME.
The current value of is set in the old time register OLDT, thereby storing the current event occurrence time. In this way, in response to an event (change in setting state) of a setting operator, duration data D(i, P(i)) related to the previous event order and event data E(i, P(i)) related to the current event order are generated. (i)+1) is written. If the value of pointer P(i) reaches the maximum value 19 due to the increment in step 123, step 125 becomes YES, and steps 93 to 9 in FIG.
The pad assignment process is completed by performing steps 127 to 129 that are exactly the same as the process in step 5.

--Processing during playback sound production--In the case of the second embodiment, the pad-on event process shown in FIG. 6 is changed as shown in FIG. 18 as a process related to playback sound production of the pad-assigned sound. In FIG. 18, steps 130 to 134 are added. Also, steps 39 and 42 in FIG. 6 are replaced by steps 39 and 42 in FIG.
In this case, steps 390 and 420 have been changed. first,
The case of simultaneous sound mode will be explained. When a desired pad is turned on, the pad on event process shown in FIG. 18 starts. In the case of the simultaneous sound mode, the pad mode data of the turned-on pad is PM (PN) = 0, so in FIG. 18, the determination in step 38 is YES, and the processing in steps 130, 131, 390, and 40 is performed. . In step 130, the volume setting data VOL (
PN) and store it in the volume data buffer VOLB.
Store in UF. In step 131, auto-harmony data AH (PN) is read from the pad memory PDM (PN) corresponding to the pad that has been turned on, and accordingly, auto-harmony effect on/off data and type data are stored in a predetermined buffer register. Setting/memory. In step 390, similarly to step 39 in FIG.
and read the pad assigned sound data PAT (PN),
The musical tone signal generation circuit 1 assigns a plurality of sounds corresponding to this pad assigned sound data to different channels.
7, musical tone signals of these plural tones are formed and generated using tones corresponding to the pad tone color data. At this time, the volume of these plural pad tones is determined by the volume setting data of the volume data buffer VOLBUF. This step differs from step 39 in FIG. 6 in the point of control.

The auto-harmony sound addition process is performed in the main routine (FIG. 16) in accordance with the auto-harmony effect on/off data and type data stored in a predetermined buffer register in step 131. In this way, multiple tones assigned to the pad are sounded, and the volume setting state and auto-harmony effect setting state assigned and memorized 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 the addition of the autoharmony sound is controlled in accordance with the reproduced autoharmony effect setting state. Next, the case of sequence sound generation mode will be explained. If the pad mode corresponding to the pad that has been turned on is the sequence sound generation mode, PM(PN)="1", so in FIG. In step 132, it is checked whether the value of the pointer P (PN) corresponding to the turned-on pad is a 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 sequence sound generation control is completed, the pointers are set to &HFF. Therefore, the value of pointer P (PN) is &HF
Being F means that the sequence sound is not in the middle of being produced. In other words, if P(PN)=&HFF is determined to be YES in step 132 of FIG. 18, it means that the current pad-on operation is for starting the generation of sequence sounds. Therefore, step 1
If 32 is YES, steps 133 and 134 are performed, and then the process goes to step 41, where sequence sound generation processing is started.

The processing in steps 133 and 134 is the same as the processing in steps 130 and 131 described above. That is, the pad memory PDM (P
Reads the volume setting data VOL (PN) from N) and stores it in the volume data buffer VOLBUF. Also reads the auto harmony data AH (PN), and according to this reads the auto harmony effect on/off data and type data. is set and stored in a predetermined buffer register. In step 41, the pointer P(PN) in the pad memory PDM(PN) of the turned-on pad is
is set to 0 to indicate the initial event order. In the next step 420, similar to step 42 in FIG. 6, the sequence data area (
The event data E(PN) of the first event order indicated by the pointer P(PN)=0
, 0) and duration data D (PN, 0) are read out, and the sound corresponding to the key code indicated by the event data E (PN, 0) is produced.
The volume of this pad sound is set to the volume data buffer VOLBUF.
This differs from step 42 in FIG. 6 in that the control is performed based on the volume setting data. The subsequent steps 43 to 45 are the same as in FIG.

As described above, the process of generating the sequence sound of the first event order assigned to the pad is performed. Processing of the second and subsequent events is performed in the sequence control process shown in FIG. FIG. 20 shows almost the same process as FIG. 11, and the only difference is step 109 in FIG. 11, which is shown as step 1090 in FIG. As mentioned above, when the current value of 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 specified by PN is
The current value of pointer P (PN) of DM (PN) is read, and the event data of the event order indicated by the pointer P (PN) is read from the sequence data area (see c in FIG. 15) of the pad memory PDM (PN). E(PN,
P(PN)) and duration data D(PN, P(P
N)) is read, and the corresponding event data E(PN, P(P
N)) Performs processing to produce or mute the sound corresponding to the key code indicated by (N)), or to set the tone, volume, effect, etc. If the event code of the event data E(PN, P(PN)) indicates a key press, a sound generation process is performed, and if it indicates a key release, a mute process is performed. During this pronunciation process,
The volume of the generated sound is controlled by the volume setting data of the volume data buffer VOLBUF. Further, if the event code of the event data E(PN, P(PN)) indicates an event of various setting operators, the setting data content is changed according to the event content data associated with the event code. That is, if the event code is a volume event, volume setting data stored as event content data is stored in the volume data buffer VOLBUF. Further, if the event code is an auto-harmony event, auto-harmony data (that is, auto-harmony effect on/off data or type data) stored as event content data is set and stored in a predetermined buffer register. Following steps 110-11
The process in step 4 is the same as in FIG.

[0071] In this way, the plurality of sequence sounds assigned to the pads are sequentially produced, and the tones, volumes, and volume assigned to the pads are changed over time.
The setting state of the auto harmony effect etc. is reproduced over time, the tone and volume of the pad sound are controlled according to the reproduced tone and volume setting data, and the setting state of the auto harmony effect etc. is controlled according to the reproduced tone and volume setting data. Additional control of the harmony sound is performed. In the example shown in FIG. 20, when a pad is pressed once more during the production of a sequence sound corresponding to an arbitrary pad, the production of the sequence sound is automatically stopped. In other words, during the generation of sequence sounds, the pointer P (PN
) has a value other than &HFF, so when the same pad is pressed again, the determination in step 132 of FIG. 20 is NO. As a result, steps 46 and 47
, perform sequence end processing, and set pointer P (PN
) to &HFF.

[0074]

[Effects of the Invention] As described above, according to the present invention, any plurality of sounds can be assigned to one performance operator, and this assignment can be changed freely.
Depending on the purpose of the performance, desired multiple tones can be assigned to the performance operator at any time, and the desired multiple tones can be easily generated by operating the performance operator once. It has excellent effects. In addition, there is a first mode in which multiple tones are generated simultaneously in response to the operation of a single performance operator, and a first mode in which multiple tones are generated sequentially in response to the operation of one performance operator. By providing a mode selection means capable of selecting two modes, it is easy to perform either simultaneous performance of multiple notes such as chords or performance of sequenced notes depending on the mode selected corresponding to each operator. This makes it possible to perform a performance that mixes two different modes of performance, which has the excellent effect of greatly improving performance performance.

Furthermore, when assigning arbitrary sounds to the performance controls, various setting controls such as volume and effects are set to desired settings, and this setting information is also stored.
In response to the subsequent operation of the performance controller, it generates a musical tone corresponding to the note assigned to the performance controller, reads out the stored setting information, and controls the musical tone or effects according to this setting information. Since the addition control etc. are performed, when playing back the assigned sound, it is possible to reproduce the desired settings of the various setting controls all at once. It is easy to set various effects, and has excellent reproducibility.
This has the excellent effect of further improving performance performance. Further, when a plurality of performance operators are provided, different setting states can be assigned to each performance operator, so performance performance can be improved in this respect as well. For example, if you operate multiple performance controls at the same time,
When producing the assigned tones, the musical tones can be controlled or given effects in different setting states for each sound corresponding to each performance operator, so that unprecedented performance effects can be obtained. In addition, while assigning arbitrary multiple notes in order in an arbitrary pronunciation order in response to the performance controller, in response to this assignment,

When this performance operator is operated, a plurality of sounds assigned to the performance operator are generated in sequence, and changes in the setting state are reproduced over time based on the memory of the storage means. Since the musical tone control or effect adding control is performed according to the set state, it is not only possible to easily perform sequence sounds, but also the setting state for various musical tone control or effect adding control can be automatically performed. Since it is possible to change the time sequentially, an unprecedented performance effect can be obtained, and it is easy to operate and has excellent reproducibility.
