The execution of the "data readout process" ends. Meanwhile, like this
During the repeated execution of the “song play process”, the event
Time has elapsed since the readout of the
When the count data TC becomes equal to the time data TIME,
In step 361, “YES” is determined, and in step 362
The pattern data pointer PTDP is incremented by "1" and
The program proceeds to the process consisting of steps 363 to 365
You. In the process consisting of steps 363 to 365,
Similar to the processing of steps 357 to 359 described above,
The performance data read from the memories 34a and 34c is time data TIM.
Until E, performance data (event data EVENT) is read
The output is continued to be output to the tone signal forming circuit 25. Soshi
When time data TIME is read out as performance data
In this regard, based on the determination of “NO” in step 363,
Tempo count data TC is initialized to “0” at step 366
Is set. And pattern end as performance data
Until PTEND is read from pattern memories 34a and 34c,
It is determined as “NO” in step 367 and in step 369
The execution of the “pattern data read process” ends. this
Is stored in the pattern memories 34a and 34c
As performance data is read out over time,
A percussion sound corresponding to the performance data is generated. After more time has passed, the pattern memories 34a and 34c
Pattern end PTEND is read out as performance data
Is determined to be “YES” in Step 367, and Step 368
Changes the sequence read flag SR to “1”
At step 369, the execution of the "pattern data reading process"
Will end. Then, the “song play process” (FIG. 9) is executed.
Starting at Tep 300, in this case, the sequence
The sleed flag SR is determined in step 368 (FIG. 10).
Is set to "1" by the

Are sequentially read out, and the sheets read out in step 302 are read out.
Kensdata SDAT is a repeat beginner RBGN (see Fig. 3C)
Is reached, the sequence data point
After stepping through the SDP, "NO" is determined in step 304.
At the same time, a determination of “YES” is made in step 311 and the
Repeat start address RSA is sequenced in step 312
Set to data pointer value SDP. In this case, repeat
The start address RSA is the next address of the repeat gin RBGN.
Less. After step 312,
After the processing of step 308, at step 310
The execution of the process ends. Next, when the execution of the “song play process” starts,
According to the processing in step 303 of the previous “song play processing”
The sequence data pointer SDP is a repeat begin RBG
Since the pattern number PTNNO following N is shown,
By the processing of steps 302 to 307, the next pattern number
Performance data in the pattern data specified by PTNNO
Is read out, and a percussion sound signal is generated according to the data.
Controlled. In this way, the sequence memory
The data in 34e is read and the same data is
When it becomes REND, "NO" in steps 304 and 311 respectively
Is determined, and “YES” is determined in step 313.
Then, the processing after step 314 is executed. This place
In this case, since the first flag FT is set to “1”,
In step 314, “YES” is determined, and in step 315
Change pattern address CPA is the current sequence data
Set to the value SDP-2 obtained by subtracting “2” from the pointer value SDP
Is done. In this case, the change pattern address CPA is
The last pattern number PTNNO at the time of repetition is stored.
Address of the last pattern
PTNNO stores the current sequence data as shown in Figure 3C.
Pointer value SDP (address following repeat end REND
At the address immediately before the address indicated by
Because it is remembered. After the processing in step 315, in step 316
Repeat data while increasing the SDP
REND next pattern REND and pattern number PTNN
O is read from the sequence memory 34e and the
Data CNT and replacement pattern data CPTN
Is determined. In this embodiment, the number of repeats
Is set to “3”, and the count data CNT is
"3". Next, in step 317, the first flag
After the FT is changed to "0", the program proceeds to step 318.
Proceed to the following. In step 318, the sequence data pointer S
DP is set to the repeat start address value RSA. Next
In step 319, the count data CNT is set to "1".
Is subtracted, and at step 320, the data CNT is "0".
Is determined. In this case, the count data
At the moment, CNT was initially set to "3"
"2", and is determined to be "NO" in step 320.
After the processing of step 308,
The execution of the “play processing” ends. Then, again, "Song play processing" step
Starting at 300, the sequence data pointer SDP is
By the processing of the step 318, the sequence memory 34e
Since it indicates the next address of repeat begin RBGN,
The pattern number PTNNO stored at the same address is
It is read every time. In this way, the sequence
The data in the sense memory 34e is sequentially read, and
When the received data reaches the repeat end REND, the step
The determination at 313 is YES, and the program is the same as above.
The process proceeds to step 314 and subsequent steps. In this case,
By the processing in step 317, the first flag FT is set to “0”
Is determined as “NO” in step 314
In step 318, the sequence data pointer SDP is
Set to repeat start address value RSA again
At the same time, at step 319,
“1” is subtracted. Then, in step 320, the lid
Each time, it is determined whether the count data CNT is “0” or not.
Is determined, but the repeat
Pattern number PTNNO between repeat RBGN and repeat end REND
Repeated reading reaches the number of repeats RCNT, that is, 3 times
Until this, the count data CNT does not become “0”.
No. This allows reading of the pattern number PTNNO of the section.
The same is done up to three times, and at the end of the third time,
“YES” in step 320, that is, the count data CN
T is determined to be "0", and the last flag is determined in step 321.
LT is changed to “1”. After the last flag LT is thus changed to “1”,
That is, the fourth repetitive reading is performed.
And in step 351 of the "pattern data reading process"
"YES", that is, it is determined that the last flag LT is "1".
Then, in step 352, the sequence data pointer SDP is
Change Pattern Address CPA
It is. In this case, the change pattern address CPA is
By the processing in step 315 (FIG. 9), the repeat
Address value before REND, that is, the end of the repetition section
Since it indicates the address value of the pattern number PTNNO (3rd
C), the sequence data pointer SDP
Value until the value of the
The program proceeds to step 356 based on the determination of `` O ''.
Then, the same processing as described above is executed. On the other hand, the sequence data pointer SDP
When the address becomes equal to the
Is determined as “YES”, and the pattern name data is
The data PTN is set to each data value CPTN of the replacement pattern.
As a result, by the above-described processing after step 356,
Replacement pattern data Pattern data corresponding to CPTN
Performance data in the memory is sequentially read from pattern memories 34a and 34c
Will be done. After the processing of the step 353, the sequence
"3" is added to the data pointer SDP, and step 355 is performed.
In the first flag FT and the last flag, LT is “1”,
Initially set to “0”. In this case, the sequence
The reason for adding "3" to the data pointer DSP is
Is the address corresponding to the current repeat end REND
And the indicated position is the number of repeats RCNT and
The next pattern number that skipped the replacement pattern number PTNNO
