The player operates the cursor movement operator group 26 and the other operator group 27 and sets the electronic musical instrument to the tone color selection state by using the display on the display 28. Thereafter, when one of the 128 timbres is designated by operating the ten key operator group 22, the CPU 51 starts execution of the timbre selection processing routine in step 100 of FIG. Then, in step 101, a voice data group corresponding to the designated timbre from the voice data 54A-1... 54A-128 in the voice data library 54A is written into the voice edit buffer 54C, and

Next, when any key is pressed on the keyboard 10, the CPU 51 starts execution of a key-on processing routine in step 200 in FIG. Key number KD for note number
Set as Note that each key of the keyboard 10 is assigned a note number that is sequentially increased by “1” as the pitch increases. After the processing in step 201, in step 202, the mode data in the voice edit buffer 54C is read to determine which of the first to fourth modes the mode data indicates. By this determination, the CPU 51 executes any one of the key-on / first to fourth mode processing routines in steps 203 to 206, and executes this key routine in step 207.
The execution of the ON processing routine ends.

When the pressed key is released,
The CPU 51 starts execution of the key-off processing routine in step 400 of FIG. 13, and sets a note number corresponding to the released key as key data KD in step 401. Then, by the determination processing of step 402, the voice edit buffer 54C
Steps 403 to 406 based on the mode data in
Then, any one of the key-off / first-fourth mode processing routines is executed, and the execution of this key-off processing routine is terminated at step 407. Hereinafter, the first to fourth modes as usage modes of the keyboard 10 specified by the mode data will be described in order.

A. First Mode First, the operation of the first mode will be described. As described above, when any key is pressed on the keyboard 10, the CPU
Step 51 is performed on condition that the mode data in the voice edit buffer 54C indicates the first mode by executing the above-described key-on processing routine of FIG.
A key-on / first mode processing routine of 03 is executed.
This key-on / first mode processing routine is shown in detail in FIG. After this start, the CPU 51 determines in step 211 that
It is determined whether or not the input key data KD (set to the note number corresponding to the pressed key pitch) indicates the note number of the pitch C1 corresponding to the lowest key of the keyboard 10. . If the key data KD indicates the note number of the pitch C1, "YE" in step 211
Based on the determination of "S", the program proceeds to step 212 and subsequent steps.

In step 212, the pattern number PTN and the shift data SHT are set to "0". Next, at step 213, the pattern number PTN is stored in the edit buffers 54C and 54D.
The pointer PO is set at the head address of the pattern data specified by the following. In this case, the pattern number PTN
Is "0", the pointer PO is set to the start address of the pattern data # 0 in the voice edit buffer 54C, that is, the storage address value of the step length data of the pattern data # 0. Next, the CPU 51
In step 214, the step length data designated by the pointer PO is read out and output to the timer 52,
At step 215, a signal for instructing the timer 52 to start operating is output. Thereby, the timer 52 inputs and stores the step length data, and thereafter,
The timer interrupt signal is started to be output to the CPU 51 at each time interval represented by the step length data and the tempo set by using the other operator group 27 and the display 28.

After the processing of step 215, the CPU 51
In step 216, the pointer PO is advanced to read the first step data including the note number and the gate time in the pattern data # 0. Next, step 21
In step 7, the read first step data is output to the tone signal generating circuit 60, and in step 219, the execution of the key-on / first mode processing routine is terminated. The tone signal generation circuit 60 forms a tone signal having a pitch corresponding to the note number and of the prepared tone color, and starts outputting the tone signal through the sound system 61. Then, when a time corresponding to the input gate time elapses, the tone signal generating circuit 60 attenuates the tone signal that has started to be generated, and thereafter ends the generation of the tone signal.

Thereafter, when a timer interrupt signal is output from the timer 52 to the CPU 51, the CPU 51
In step 300 of FIG. 12, execution of the step processing program is started. After the start, in step 301, the pointer PO is advanced to read the next step data including the note number and the gate time in the pattern data # 0. Next, in step 302, the shift data SHT is added to the note number in the read step data. However, in this case, since the shift data SHT is set to “0”, the note number is not changed. After the processing of step 302, the read step data is output to the tone signal generation circuit 60 in step 303. As a result, the tone signal generating circuit 60 forms a tone signal of the prepared tone color having a pitch corresponding to the note number and outputs it through the sound system 61, as in the case described above.

After the processing in step 303, step 3
At step 04, it is determined whether or not the read step data is the 16th data. Otherwise, based on the determination of “NO” at step 304, this step The execution of the processing program ends.
Then, also when the timer 52 next outputs a timer interrupt signal to the CPU 51, the step processing program is executed to control the generation of the tone signal. Therefore, the tone signal generation circuit 60 sends the tone color parameters of the buffer 54C and the first to fourth data in the pattern data # 0 at the time interval represented by the step length data in the pattern data # 0 in the voice edit buffer 54C.
Tone signals defined by the sixteenth step data are sequentially generated.

On the other hand, if the step data read in step 301 corresponds to the sixteenth data, the pointer is moved to the same pattern in step 305 based on the determination of "YES" in step 304. Update to the storage location of the first step data in data # 0. Therefore, the tone signals defined by the first to sixteenth step data are continuously and repeatedly generated.

If the pressed key (the key corresponding to the pitch C1) is released during the sequential generation of the tone signals, the CPU
Reference numeral 51 denotes a key-off / first mode processing routine of step 403 in FIG. 13 on condition that the mode data in the voice edit buffer 54C indicates the first mode by executing the above-described key-off processing routine of FIG. Run. This key-off / first mode processing routine is shown in detail in FIG. 14, and the execution of this routine is started at step 410. After this start, step 411
"YES", that is, the key data K representing the released key.
It is determined that D is the note number representing the pitch C1, and the program proceeds to steps 412 and 413. In step 412, a sequence end signal is output to the tone signal generation circuit 60, and in step 413, the timer 52
At step 415, and terminates the execution of the key-off / first mode processing routine at step 415. The tone signal generation circuit 60 ends the generation of the tone signal based on the pattern data # 0. The timer 52 thereafter stops generating the timer interrupt signal. Therefore, until the key corresponding to the pitch C1 is pressed next time, the sequential generation of the tone signal based on the pattern data # 0 is interrupted.

On the other hand, when a key other than the pitch C1 is pressed,
The CPU 51 executes the key-on processing routine shown in FIG. 7 to execute the key-on / first
Start execution of the mode processing routine. Then, "NO" in step 211, that is, step 20 in FIG.
It is determined that the key data KD set in the process 1 does not indicate the pitch C1, and the program proceeds to step 218. In step 218, the key data K
D and key-on data KON are output to the tone signal generation circuit 60. The tone signal generation circuit 60 is adapted to generate the key data K
A tone signal having a pitch corresponding to D starts to be generated with the prepared tone color defined by the tone color parameter in the voice edit buffer 54C.

When the pressed key is released, the CPU 51 starts execution of the key-off / first mode processing routine in step 410 of FIG. 14 by executing the above-described key-off processing routine of FIG. . Then, in step 411, it is determined that “NO”, that is, the key data KD set in the process of step 401 in FIG. 13 does not indicate the pitch C1, and the program proceeds to step 414. In step 414, the key data KD and key-off data KOF are output to the tone signal generating circuit 60, and in step 415, the execution of the key-off / first mode processing routine is terminated. The tone signal generation circuit 60 attenuates the tone signal being generated relating to the key data KD, and thereafter stops generating the tone signal.

As described above, in the first mode, when the key corresponding to the pitch C1 of the keyboard 10 is pressed, the tone signal of the pitch specified by the pattern data # 0 in the voice edit buffer 54C is generated. The tone signals are automatically generated sequentially, and the release of the key stops the generation of the automatically generated tone signals. Also, during the automatic generation of the musical tone signal, the performer can perform a normal performance using a key other than the pitch C1. The timbre of the tone signal generated by the performance of the performer and the tone color of the automatically generated tone signal are the same as those specified by the timbre parameters selected by the performer and stored in the voice edit buffer 54C. It is a tone. Further, the pattern data # 0 used for the automatic performance belongs to the same voice data group together with the timbre parameter, and these data are simultaneously selected by the timbre selection.
4C, the tone parameter and the pattern data # 0 of an appropriate combination are prepared in advance, and the tone parameter and the pattern data # 0 are appropriately combined by an editing operation by a player described later. Thus, the player can simultaneously generate automatic performance sounds suitable for the performance sounds of the keyboard by a simple operation.

B. Second Mode Next, the operation of the second mode will be described. As described above, when any key is pressed on the keyboard 10, the CPU
Step 51 is performed on condition that the mode data in the voice edit buffer 54C indicates the second mode by executing the above-described key-on processing routine of FIG.
A key-on / second mode processing routine of 04 is executed.
This key-on / second mode processing routine is shown in detail in FIG. The processing in steps 221 to 228 is performed in step 222
, Except that the shift data is not set to “0” in step S 227 and that the shift data SHT is added to the note number in the first step data in step 227. Processing is the same. Therefore, if the player presses the key corresponding to the pitch C1, the shift data SHT is added to the note number of the pattern data # 0 in the voice edit buffer 54C by executing the steps 221 to 228 and the step processing program of FIG. Are automatically generated in sequence in the tone color specified by the tone color parameter in the buffer 54C.

When the pressed key (key corresponding to the pitch C1) is released during the sequential generation of the tone signals, the CPU
Reference numeral 51 denotes a key-off / second mode processing routine in step 404 in FIG. 13 on condition that the mode data in the voice edit buffer 54C indicates the second mode by executing the above-described key-off processing routine in FIG. Run. This key-off / second mode processing routine is shown in detail in FIG. 15, and the execution of this routine is started at step 420. The processing of steps 421 to 423 is the same as the processing of steps 411 to 413 in the case of the first mode. In this case, since the released key corresponds to the pitch C1, the automatic tone signal The occurrence is interrupted.

On the other hand, when the player presses a key other than the pitch C1 and a key in the lower key range, the key data KD set in step 201 of FIG. (C #
1 to B2). Here, SP indicates the division point, that is, the note number corresponding to the lowest key (C3) in the upper key area. Therefore, in this case, “NO” is determined in step 221 of FIG. 9, and “YES” is determined in step 228, and the program proceeds to step 230. In step 230,
The note number of the pitch C # 1 is subtracted from the key data KD, and the result of the subtraction is set as shift data SHT. For example, if the key corresponding to the pitch C # 1 is pressed, the shift data SHT is set to “0”. If the key corresponding to the pitch D1 is pressed, the shift data SHT is set to "1". When the pressed key is released, the determination in step 421 or 424 of FIG. 15 is both "NO", and the execution of the key-off / second mode processing routine is terminated in step 426. .

Therefore, in the second mode, the pitch C
If a key belonging to # 1 to SP-1 is pressed, the shift data SH
The value of T is set to various values according to the key pressed. Then, after that, when the key corresponding to the pitch C1 is pressed, the pitch corresponding to the note number of the pattern data # 0 in the voice edit buffer 54C is shifted to the shift data S.
Tone signals with a pitch shifted by HT are automatically generated sequentially. Further, by pressing the keys belonging to the pitches C # 1 to SP-1 while pressing the key corresponding to the pitch C1, it is possible to change the pitch to be shifted in the middle of the pitch data being sequentially generated. is there.

Further, when the player presses a key belonging to the upper key range (C3 to C6), the key data KD set in step 201 in FIG. In steps 221 and 229 of FIG. 9, both are determined to be “NO”, and the program proceeds to step 231. If this key is released, step 4 in FIG.
Since the key data KD set at 01 is equal to or greater than the note number corresponding to the pitch SP, step 42 in FIG.
The determination is “NO” at 1 and “YES” at step 424, and the program proceeds to step 425. The processes of steps 231 and 425 are performed in step 218 of FIG. 8 and step 41 of FIG. 14 in the case of the first mode.
4 is the same as the processing of FIG. Therefore, in the second mode, the player can freely perform using the keys in the upper key range while generating the automatic performance sound.

C. Third Mode Next, the operation of the third mode will be described. As described above, if any key is pressed on the keyboard 10, the CPU
Step 51 is performed on condition that the mode data in the voice edit buffer 54C indicates the third mode by executing the above-described key-on processing routine of FIG.
The key-on / third mode processing routine of 05 is executed.
This key-on / third mode processing routine is shown in detail in FIG. The processing of steps 241 to 247 is the same as the first
This is the same as the processing in steps 211 to 217 of the mode.

When the pressed key is released,
The CPU 51 executes the key-off / third mode processing routine of step 405 of FIG. 13 on condition that the mode data in the voice edit buffer 54C indicates the third mode by executing the above-described key-off processing routine of FIG. Run. The key-off / third mode processing routine is shown in detail in FIG. The determination process of step 431 is a process of determining whether or not the key data KD indicates a key belonging to the lower key area (note number is equal to or less than SP-1). This is the same as the processing in steps 412 and 413 in the case of the one mode.

Therefore, also in the third mode,
By pressing and releasing the key corresponding to the pitch C1, the tone signal of the pitch corresponding to the note number of the pattern data # 0 in the voice edit buffer 54C is generated in the same manner as in the first mode. Are automatically generated in sequence with the timbre specified by the timbre parameter, and the generation is stopped.

On the other hand, when the player presses a key other than the pitch C1 and a key in the lower key range, the key data KD set in step 201 of FIG. Indicates the note number belonging to. Therefore, in this case, “NO” is determined in step 241 of FIG. 10, and “YES” is determined in step 248, and the program proceeds to step 249 and subsequent steps. In step 249, the pattern select data in the voice edit buffer 54C is read, and the key data KD is stored in the read data.
Then, a value obtained by subtracting the note number corresponding to the pitch C # 1 from the above is added, and the result of the addition is set as the pattern number PTN. For example, if the key corresponding to the pitch C # 1 is pressed, the pattern number PTN remains set to the pattern select data value. If the key corresponding to the pitch D1 is pressed, the pattern number PTN is set to a value smaller than the pattern select data value. 1 "
Is set to a larger value.

After step 249, step 2
After setting the shift data SHT to "0" at 50, the processing of the steps 243 to 247 is executed. However,
In this case, the pattern number PTN is different from the above case, and indicates one of the pattern numbers # 1 to 128. Therefore, in step 243, the pointer PO stores the start address of one of the pattern data # 1 to # 128 in the pattern edit buffer 54D, that is, the step length data of any of the pattern data # 1 to # 128. Set to the address value. As a result, by executing the following steps 244 to 247 and the step processing program shown in FIG. The tone is automatically generated in sequence with the tone specified by the tone parameter in the buffer 54C.

When the pressed key is released,
The CPU 51 determines “YES” in step 431 of FIG.
Is determined, and the program is executed in steps 432 and 43 described above.
Proceed to 3. By the processing of steps 432 and 433, the automatic generation of the tone signal is stopped.

Therefore, in the third mode, the pitch C
By depressing and releasing a key corresponding to the pitch belonging to 1 # to SP-1, any one of the pattern data # 1 to # 128 in the pattern edit buffer 54D is pressed according to the pressed key pitch. Tone signals based on the selected pattern data are automatically and sequentially generated, and the generation is stopped. While pressing any key in the lower key range,
When another key in the lower key range is pressed, in addition to the automatic performance based on the previous key depression, the automatic performance based on the new key depression is performed in parallel.

Further, when the player presses a key belonging to the upper key range, the key data KD set in step 201 of FIG.
Is higher than the note number corresponding to the pitch SP,
In steps 241 and 248 of FIG. 10, both are determined to be “NO”, and the program proceeds to step 251. Also,
When this key is released, the key data KD set in step 401 of FIG. 13 also becomes greater than or equal to the note number corresponding to the pitch SP.
O "is determined, and the program proceeds to step 443.
The processing of step 251 and step 434 is the same as that of the first
This is the same as the processing in step 218 in FIG. 8 and step 414 in FIG. 14 in the case of the mode. Therefore, this third
In the mode, the player can freely perform using the keys in the upper key range while generating the automatic performance sound.

D. Fourth Mode Next, the operation of the fourth mode will be described. As described above, when any key is pressed on the keyboard 10, the CPU
Step 51 is performed on condition that the mode data in the voice edit buffer 54C indicates the fourth mode by executing the above-described key-on processing routine of FIG.
The key-on / fourth mode processing routine of 06 is executed.
This key-on / fourth mode processing routine is shown in detail in FIG. 11, and its execution is started at step 260. The processing of steps 261 to 268 is the same as that of the second
This is the same as the processing in steps 221 to 228 of the mode.

When the pressed key is released,
The CPU 51 executes the key-off / fourth mode processing routine in step 406 in FIG. 13 by executing the above-described key-off processing routine in FIG. 13 on condition that the mode data in the voice edit buffer 54C indicates the fourth mode. Run. This key-off / fourth mode processing routine is shown in detail in FIG. 17, and the execution of this routine is started at step 440. Steps 441-44
The processing of step 3 is performed in steps 431 to 4 of the third mode described above.
33 is the same as the process.

Therefore, also in the fourth mode,
By pressing and releasing the key corresponding to the pitch C1, the pitch obtained by adding the shift data SHT to the pitch corresponding to the note number of the pattern data # 0 in the voice edit buffer 54C in the same manner as in the third mode. Are automatically generated in sequence with the timbre specified by the timbre parameters in the buffer 54C, and the generation is stopped.

On the other hand, when the player presses a key other than the pitch C # 1 and a key in the lower key range, the key data KD set in step 201 of FIG. This indicates the note number belonging to -1. Therefore, in this case, “NO” is determined in step 261 of FIG.
At step 269, “YES” is determined, and the program proceeds to step 270 and subsequent steps. The processing in step 270 is the same as the processing in step 249 in the third mode described above, and the processing in steps 263 to 268 is the same as the processing in steps 223 to 228 in the second mode.

When the pressed key is released,
The CPU 51 determines “YES” in step 441 of FIG.
And the program is stored in steps 442 and 44 described above.
Proceed to 3. The processing in steps 442 and 443 is the same as the processing in steps 432 and 433 in the third mode described above.

Therefore, also in the fourth mode,
By pressing and releasing a key corresponding to any one of the pitches C # 1 to SP-1, the pattern data # 1 to # 12 in the pattern edit buffer 54D as in the case of the third mode.
8 based on the pattern data selected in accordance with the pressed key pitch, and the tone signal of the pitch obtained by adding the shift data SHT to the note number of the pattern data is stored in the voice edit buffer 54C. The tone is automatically generated sequentially with the tone specified by the tone parameter, and the generation is stopped.

Further, when the player presses a key belonging to the upper key range, the key data KD set in step 201 of FIG.
Is higher than the note number corresponding to the pitch SP,
In steps 260 and 268 of FIG. 11, both are determined to be “NO”, and the program proceeds to step 271. In step 271, the pitch SP is calculated from the key data KD.
Is subtracted, and the result of the subtraction is set as shift data SHT. For example, pitch SP (C
If the key corresponding to 3) is pressed, the shift data SHT is set to "0". If the key corresponding to the pitch SP + 1 is pressed, the shift data SHT is set to "1". Also,
If the pressed key is released, "NO" is determined in the step 441 of FIG. 17, and the execution of the key-off / fourth mode processing routine is ended in a step 444.

Therefore, in the fourth mode, if a key in the upper key range (pitch SP or more) is pressed, the value of the shift data SHT is set to various values according to the pressed key. After that, if the key corresponding to the pitch C1 is depressed, the tone signal corresponding to the note number of the pattern data # 0 in the voice edit buffer 54C is automatically shifted in sequence by the shift data SHT. Is generated. If a key corresponding to pitch C # 1-SP-1 is pressed, the pitch corresponding to any one of the note numbers of pattern data # 1- # 128 in pattern edit buffer 54D is shifted by shift data SHT. The tone signals of the selected pitches are sequentially and automatically generated. Also, pitches C1 to S
By pressing a key belonging to the pitch SP or higher while pressing the key corresponding to P-1, it is possible to change the pitch to be shifted in the middle of the pitch data being sequentially generated.

Next, the operation of editing various data in the voice data library 54A, the pattern data library 54B, the voice edit buffer 54C and the pattern edit buffer 54D will be described.

The player operates the cursor movement operator group 26 and the other operator group 27 and uses the display on the display 28 to set the electronic musical instrument to the tone parameter edit state. Operator group 2
When a part of the timbre parameter is specified and the parameter value is input by the second or other operation group 27, the CP
U51 executes the tone color parameter edit processing routine of FIG. This tone parameter edit processing routine includes steps 500 to 502, and step 5
By the process of 01, the value of the specified tone color parameter in the voice edit buffer 54C is rewritten to the input parameter value. Thereby, the tone of the performance sound of the keyboard 10 and the automatic performance sound based on the pattern data # 0 to # 128 can be variously changed.

The player sets the electronic musical instrument to the mode data edit state by the same operation as described above, and thereafter operates the ten key operator group 22 or the other operator group 27 to operate the electronic musical instrument. When any one of the fourth modes is designated, the CPU 51 executes the mode edit processing routine of FIG. This mode edit processing routine includes steps 510 to 512, and rewrites the mode data in the voice edit buffer 54C to the specified mode number by the processing of step 511. As a result, the use state of the keyboard 10 can be selected from any of the above-described first to fourth modes corresponding to the selected tone (selected voice).

The player sets the electronic musical instrument in the pattern select data edit state by the same operation as described above, and then operates the ten key operator group 22 or the other operator group 27 to perform pattern selection. When the number is input, the CPU 51 executes a pattern select data edit processing routine shown in FIG. This pattern select data edit processing routine includes steps 520 to 522, and the process of step 521 rewrites the pattern select data in the voice edit buffer 54C to the input pattern select number. Thus, in the third or fourth mode, any pattern data in the pattern edit buffer 54D can be selected in accordance with the selected tone (selected voice).

When the player sets the electronic musical instrument to the step data editing state by the same operation as described above, the CPU 51 repeatedly executes the step data editing processing routine shown in FIG. The repetitive execution of the step data edit processing routine is stopped by canceling the step data edit state.

In this step data edit processing routine, the pattern number PTN for designating the pattern data is stored in the step 104 shown in FIG.
Step 212 in FIG. 8, step 222 in FIG. 9, FIG.
Steps 242 and 249 of FIG.
2, 270.

The execution of the step data edit processing routine is started in step 530, and in step 531, the step operators 21-1, 212-2,.
It is determined whether any one of 1-16 has been operated. This determination is made by comparing the previous rotation position with the current rotation position for each step operator, thereby detecting that both positions have changed. If any one of the step operators 21-1, 21-2,..., 21-16 is operated, "YE"
S ”, the CPU 51 determines in step 532 that the pattern number PT among the pattern data # 0 in the voice edit buffer 54C and the pattern data # 1 to # 128 in the pattern edit buffer 54D.
N in the step data corresponding to the operated step operators 21-1, 21-2,..., 21-16 in the first to sixteenth step data. The note number is changed to the note number corresponding to the rotational position of the operated step operator. Then, at step 533, the edit flag FLG (P
TN) is set to "1" and the program is executed at step 534,
Proceed to 535. Step operators 21-1, 21-2
.. If none of 21-16 has been operated, the program proceeds to steps 534, 535 based on the determination of "NO" in step 531.

In steps 534 and 535, a step length changing process and a gate time changing process are executed.
In this case, the player operates the cursor movement operator group 26 and the other operator group 27 to determine the step length and the first to first.
When any one of the gate times of the sixteenth step data is input, the pattern data # 0 in the voice edit buffer 54C is obtained by the processing of steps 534 and 535.
And, among the pattern data # 1 to # 128 in the pattern edit buffer 54D, the step length and the gate time in the pattern data designated by the pattern number PTN are respectively changed to the input values. In steps 534 and 535, if the step length or the gate time is changed, the edit flag FLG (PTN) designated by the pattern number PTN is used.
Is set to “1”. Then, in step 536, the execution of the step data edit processing routine is terminated.

Thus, in the first to fourth modes, arbitrary pattern data of pattern data # 0 in the voice edit buffer 54C and pattern data # 1 to # 128 in the pattern edit buffer 54D are
Various changes can be made in relation to the selected timbre.

Next, the operation of returning the voice data group in the voice edit buffer 54C to the voice data library 54A will be described. When the player operates the voice store operator 23, the CPU 51 proceeds to step 60 in FIG.
0, the execution of the voice store processing routine is started, and in step 601, all the data (tone parameters, mode data, pattern select data, and pattern data # 0) in the voice edit buffer 54C are stored in the voice data library 54A. return. That is, the voice data group currently stored in the buffer 54C is written into the voice data library 54A at the storage position where the voice data group was previously stored in the voice edit buffer 54C. Thereby, the voice data group in the voice data library 54A is variously edited.

After the processing in step 601, step 6
At 02, it is determined whether or not the mode data in the voice edit buffer 54C indicates the third or fourth mode. If the data does not indicate the third or fourth mode, "NO" is determined in step 602, and the execution of the voice store routine is terminated in step 609.

On the other hand, if the mode data indicates the third or fourth mode, “Y” in step 602
In step 603, the program
Proceed to 607. In the processing of these steps 603 to 607, the variable i is sequentially set to “1” from “1” to “128”.
The edit flag FLG
(i) The pattern data #i in the pattern edit buffer 54D specified by the variable i with “1” is changed to the pattern data #i specified by the variable i in the pattern data library 54A. This allows
When any one of the step length data and the first to sixteenth step data is changed while the electronic musical instrument is set to the third or fourth mode, only the pattern data including the changed data is changed. The pattern data is rewritten as the corresponding pattern data in the pattern data library 54B, and the rewriting of the pattern data in the other pattern data library 54B is omitted.

According to this, only the necessary data is rewritten, and the processing time for rewriting the same pattern data can be reduced. The reason why the case of the third or fourth mode is set as the condition for rewriting the pattern data is that the mode data is changed to the third or fourth mode by the mode edit processing of FIG.
Except when the voice store operator 23 is operated immediately after changing the mode number representing the mode to the mode number representing the first or second mode, the pattern data to be edited is not included in the mode other than the third or fourth mode. This is because the pattern number PTN for designation is “1” to “128”, that is, the pattern data # 1 to # 128 in the pattern edit buffer 54D is not designated. When the voice store operator 23 is operated immediately after the change from the third or fourth mode to the first or second mode, the pattern data in the pattern data library 54B is not changed.

After the processing of steps 603 to 607, in step 608, the edit flags FLG (1) to FLG (128) indicating the change of the pattern data # 1 to # 128 in the pattern edit buffer 54D are all set to "0". After the initial setting, the execution of the voice store routine ends at step 609. According to this, the pattern data # 1 to # 128 of the pattern data library 54B can be changed to desired values.

If the player performs any tone selection operation before operating the voice store operator 23,
The voice edit buffer 54C and the pattern edit buffer 54C
D is completely discarded, and the voice data group and pattern data group # 1 to # 1 corresponding to the newly selected tone color
28 is copied from the voice data library 54A and the pattern data library 54B. Therefore, if the user does not like the edited data, he or she only has to reselect one of the tones (which may be the same as or different from the previously selected tones).

In this electronic musical instrument, the pattern data # 1 to # 1 in the pattern data library 54B are used.
One of the voice edit buffers 54
C to use the transferred pattern data, perform the above-described edit processing on the transferred pattern data, and conversely convert the pattern data # 0 in the voice edit buffer 54C into the pattern data # 1 to ## in the pattern data library 54B.
128. In the former case, the performer operates the cursor movement operator group 26 and the other operator group 27 and uses the display on the display 28 to specify the pattern number. When the on operation is performed, the CPU 51 returns to FIG.
A pattern load processing routine including Steps 610 to 612 of Step 3 is executed. Then, by the process of step 611, the pattern data # 1 to # 128 in the pattern data library 54B and the pattern data designated by the pattern number are read and stored as the pattern data # 0 in the voice edit buffer 54C.

Also, in the latter case, when the pattern save operator 25 is turned on after designating the pattern number in the same manner as described above, the CPU 51 executes the pattern save processing routine consisting of steps 620 to 622 in FIG. I do. Then, the pattern data # 0 in the pattern edit buffer 54C is obtained by the processing of step 621.
Is read and stored as pattern data # 1 to # 128 in the pattern data library 54B and designated by the pattern number. This makes it possible to more efficiently edit various pattern data.

Next, various modifications of the above embodiment of the present invention will be described.

(1) In the above embodiment, an automatic performance consisting of 16 steps of a fixed length is started by pressing a predetermined key on the keyboard 10, and the automatic performance is repeatedly performed during the key pressing. The automatic performance was stopped by key operation. However, note length data may be stored for each note number, and each step length may be different, or the number of steps may be other than 16 steps. Also, instead of repeatedly performing the automatic performance of 16 steps while the key is being depressed, the automatic performance may be terminated after performing the automatic performance of 16 steps once.
Further, after the key is depressed, the repetition of the automatic performance is continued irrespective of the key release, and the automatic performance is stopped by another switch operation.
