DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument, and more particularly, to an electronic musical instrument having a plurality of performance functions such as an automatic performance function and an automatic accompaniment function.

[0002]

2. Description of the Related Art Conventionally, a plurality of performance data are stored,
An automatic performance device that selects desired performance data from a plurality of stored performance data, reads and reproduces the selected performance data, outputs it to a sound source, and generates a musical tone based on the performance data to perform a performance. Had been.

Also, performance data composed of a plurality of accompaniment patterns having a predetermined number of measures is stored, and performance data of a desired accompaniment pattern is selected from the stored performance data composed of a plurality of accompaniment patterns. There has been known an automatic accompaniment apparatus that repeatedly reads and reproduces the performance data of the musical accompaniment, outputs the reproduced data to a sound source, and generates a musical tone based on the performance data of the accompaniment pattern to perform the accompaniment.

Further, there has been proposed an electronic musical instrument having an automatic performance function and an automatic accompaniment function in which such an automatic performance apparatus and an automatic accompaniment apparatus are integrated.

An electronic musical instrument having both the automatic performance function and the automatic accompaniment function described above has a common start command for instructing the start of the operation (reproduction of performance data) of the automatic performance function and the automatic accompaniment function. A single start switch was provided as a switch, and a single stop switch was provided as a common stop switch for instructing termination of the operations of the automatic performance function and the automatic accompaniment function. .

[0006] Therefore, the operation of the automatic performance function and the automatic accompaniment function can be started at the same time only by operating a single start switch, and the automatic performance can be started only by operating a single stop switch. The function and the automatic accompaniment function can be stopped simultaneously.

[0007]

However, in the conventional electronic musical instrument having both the automatic performance function and the automatic accompaniment function as described above, the start switch is not provided with the automatic performance function and the automatic accompaniment function. A start switch instructing the start of the operation of the automatic performance function and a start switch instructing the start of the operation of the automatic accompaniment function are provided only with a single start switch common to both of them for simultaneously starting the operation. Was not equipped with each.

In addition, the stop switch only has a single stop switch common to both the automatic performance function and the automatic accompaniment function for simultaneously stopping the operation of the automatic performance function and the automatic accompaniment function. There is no separate stop switch for instructing and a stop switch for instructing to stop the operation of the automatic accompaniment function.

For this reason, the automatic accompaniment function may be stopped during the automatic performance function, or only the automatic performance function may be started, and then the automatic accompaniment function may be started. The start and stop of the operation of the performance function and the automatic accompaniment function cannot be independently and individually controlled between the automatic performance function and the automatic accompaniment function, and a change in performance cannot be performed. There was a problem.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to integrate an automatic performance device and an automatic accompaniment device,
The operability of an electronic musical instrument having a combination of multiple performance functions, such as having an automatic performance function and an automatic accompaniment function, is improved. To provide an electronic musical instrument capable of performing a variety of performances by independently controlling the automatic performance function and the automatic accompaniment function independently of each other. And

[0011]

In order to achieve the above object, an electronic musical instrument according to the present invention comprises a first performance means for performing a performance based on first performance data and a second performance means based on a second performance data. A second performance means for performing simultaneously with the first performance means; and, when the first performance means finishes the performance, the second performance means performs a performance other than the predetermined performance data in the second performance data. If the data is being played, the second performance means is stopped at the same time, and if the predetermined performance data is being played, control is performed so that the performance is performed until the end of the second performance data. Control means.

[0019]

[0020]

According to the invention described above, when the first performance means finishes playing, the second performance means plays performance data other than the predetermined performance data in the second performance data. The control means stops the second performance means at the same time, but when playing predetermined performance data, the control means controls the performance until the end of the second performance data. I do.

Therefore, for example, the first performance means is an automatic performance means for realizing an automatic performance function, the second performance means is an automatic accompaniment means for realizing an automatic accompaniment function, and predetermined performance data is stored in an ending pattern. When the automatic performance means finishes playing all the performance data, the automatic accompaniment means stops immediately if the performance data of the normal pattern is being played, and the performance data of the ending pattern. Is being played, it does not stop until the performance of the performance data of the ending pattern ends.

With this, even if the automatic accompaniment means finishes the performance first, if the automatic accompaniment means is playing the performance data of the ending pattern, the automatic accompaniment means always performs the playback of the performance data of the ending pattern. Since it is possible to perform to the end, it is possible to prevent the performance by the ending pattern from being interrupted in the middle, so that it is possible to perform without discomfort.

If the decision result in the step S1002 is affirmative, that is, if the currently selected timing register is the timing register 1, the step S1004
Then, the timing register 2 is selected again as the timing register. Specifically, the address for specifying the timing register is changed.

When the processing in step S1004 ends, the timing selection processing routine ends, and the process returns to the switch operation processing routine.

On the other hand, since the result of the determination in step S1002 is negative, that is, the currently selected timing register is not the timing register 1 but the timing register 2, the flow advances to step S1006 to set the timing register as the timing register. Select register 1 again. Specifically, the address specifying the timing register is changed.

When the processing in step S1006 ends, the timing selection processing routine ends, and the process returns to the switch operation processing routine.

In this electronic musical instrument, the timing register 1 or the timing register 2
One of the timing registers is selected.

Next, with reference to the flowchart shown in FIG. 11, as one of the processing routines relating to the other operators in step S328, a timing setting processing routine started when the timing setting button 22h is operated is described. This will be described in detail.

That is, when the timing setting button 22h is operated, the timing setting processing routine shown in FIG. 11 is started. In this timing setting processing routine, first, in step 1102, the currently selected timing is set to the beat. It is determined whether or not it is the timing for.

If the decision result in the step S1102 is affirmative, that is, if the currently selected timing is a timing for a beat, the process advances to a step S1104 to reset the timing to a timing corresponding to a bar. Specifically, the timing register 1 and the timing register
The number of ticks corresponding to the bar is written from the register 2 to the timing register selected in the above-described timing selection processing routine.

When the processing in step S1104 ends,
The timing setting processing routine ends, and the process returns to the switch operation processing routine.

On the other hand, if the decision result in the step S1102 is negative, that is, if the currently selected timing is not a timing for a beat, the process proceeds to a step S1106 to determine whether or not the currently selected timing is a timing for a bar. Judge.

[0146] If the decision result in the step S1106 is affirmative, that is, if the currently selected timing is a timing for a bar, the flow advances to a step S1108 to reset the timing to a timing corresponding to the division. More specifically, the timing register which is selected from the timing register 1 and the timing register 2 in the timing selection processing routine described above.
The number of ticks corresponding to the division is written in the register.

When the processing in step S1108 ends,
The timing setting processing routine ends, and the process returns to the switch operation processing routine.

On the other hand, if the decision result in the step S1106 is negative, that is, if the currently selected timing is not the timing for the bar, the currently set timing is the division, so the step S1110 is executed.
Proceed to and reset the timing to the timing corresponding to the beat. More specifically, the timing register which is selected from the timing register 1 and the timing register 2 in the timing selection processing routine described above.
The number of ticks corresponding to the beat is written in the register.

When the processing in step S1110 ends,
The timing setting processing routine ends, and the process returns to the switch operation processing routine.

In this electronic musical instrument, one of the timings is always stored in the timing register.

FIG. 12 shows a tick event processing routine in step S206. First, in step S1202, it is determined whether or not the value of the tick event counter is positive. Here, the tick event counter is determined by the timer 24 from the CPU 1
2 at predetermined time intervals (for example, when the tempo is set to 100, it is “100 × 1/120” (minutes)). In the activated timer interrupt processing routine shown in FIG.
It is incremented by "1".

That is, when the CPU 12 receives the interrupt signal from the timer 24, the timer interrupt processing routine shown in the flowchart of FIG. 13 is started, and in step S1302, the tick event counter is incremented by "1".

When the processing in step S1302 ends, the timer interrupt processing routine ends, and the process returns to the main routine.

If the result of the determination in step S1202 is positive, that is, while the value of the tick event counter is positive, the process proceeds to step S1204 and the subsequent steps.
The processing after step 1204 is repeated, but if the result of the determination in step S1202 is negative, that is, if the value of the tick event counter becomes 0 or negative, the tick event processing ends and returns to the main routine.

In the step S1204, it is determined whether or not the value of the tick counter in the division matches the number of ticks stored in the timing register 1.

It is detected that the judgment result of step S1204 is affirmative, that is, the case where the value of the tick counter in the division matches the number of ticks stored in the timing register 1, that is, the set timing. If so, the flow advances to step S1206 to determine whether or not the arranger start preparation flag is set to "1".

If the decision result in the step S1206 is affirmative, that is, if the arranger start preparation flag is set to "1", the flow advances to a step S1208 to set the arranger start flag to "1". Set the arranger start preparation flag to "0". When the process in step S1208 ends, the process advances to step S1210.

On the other hand, if the decision result in the step S1204 is negative, that is, if the value of the tick counter in the division and the number of ticks stored in the timing register 1 are different, that is, if it is not the set timing, The process proceeds to step S1210 without performing any processing.

Further, even if the result of the determination in step S1206 is negative and the arranger start preparation flag is "0", step S12 is performed without any processing.
Proceed to 10.

In step S1210, the arranger
It is determined whether or not the start flag is "1".

If the determination result in step S1210 is affirmative, that is, if the arranger start flag is "1", the flow advances to step S1212 to store the value of the tick counter in the division in the timing register 2. It is determined whether or not the number of ticks matches.

It is detected that the judgment result of step S1212 is affirmative, that is, the case where the value of the tick counter in the division matches the number of ticks stored in the timing register 2, that is, the set timing. If so, the process advances to step S1214 to determine whether the composer recording flag is set to "1".

If the decision result in the step S1214 is affirmative, that is, if the composer recording flag is set to "1", the flow advances to a step S1216 to store the arranger start information in the song data. The processing in step S1216 will be described in more detail in an operation example described later. Then, step S1
Upon completion of the process in step S216, the process advances to step S1218.

On the other hand, if the result of the determination in step S1212 is negative, that is, if the value of the tick counter in the division is different from the number of ticks stored in the timing register 2, that is, if the timing is not the set timing, Is performed in step S121 without performing any processing.
Proceed to 8.

Further, if the judgment result in step S1214 is negative and the composer recording flag is "0", the flow advances to step S1218 without performing any processing.

In step S1218, step S12
Since the arranger start flag is set to "1" (indicating that the arranger 12b is being executed) in the judgment processing of No. 10, an arranger reproduction processing routine, which will be described later, is a subroutine of the tick event processing routine. Execute Then, step S12
Upon completion of the process at S18, the process proceeds to Step S1220.

On the other hand, if the decision result in the step S1210 is negative, that is, if the arranger start flag is “0”, the step S110 is performed without any processing.
Proceed to 220.

At step S1220, the composer
It is determined whether the start flag is "1".

If the result of the determination in step S1220 is affirmative, that is, if the composer start flag is "1", it means that the composer 12a is being executed, so the flow advances to step S1222 to execute the tick event processing routine. As a sub-routine, a composer reproduction process routine to be described later is executed. Then, when the process of step S1222 is completed, step S1224
Proceed to.

On the other hand, if the decision result in the step S1220 is negative, that is, if the composer start flag is “0”, the step S120 is executed without any processing.
Proceed to 224.

In step S1224, the tick counter in the division is counted up by "1", and thereafter, the flow advances to step S1226.

Then, in step S1226, the tick event counter is counted down by "1", and thereafter, the flow returns to step S1202, and while the value of the tick event counter is positive, the above-described step S1 is executed.
The processing of the loop constituted by steps 202 to S1226 is repeated.

Next, the arranger reproduction processing routine in step S1218 will be described in detail with reference to the flowchart shown in FIG.

In the arranger reproduction processing routine, first, in step S1402, it is determined whether or not the arranger ending flag is “0”.

If the decision result in the step S1402 is affirmative, that is, if the arranger ending flag is "0", the flow advances to a step S1404 to perform a normal pattern reproducing process. That is, the style data of the normal pattern is sent to the sound source 20, and the accompaniment is performed by the sound source 20 based on the style data.

On the other hand, if the decision result in the step S1402 is negative, that is, if the arranger ending flag is "1", the flow advances to a step S1406 to perform an ending pattern reproducing process. That is, the ending data, which is the style data of the ending pattern, is transmitted to the sound source 20, and the accompaniment is performed by the sound source 20 based on the ending data.

Step S1404 or step S1
Subsequent to the process of 406, in step S1408,
It is determined whether or not the value of the tick counter in the division matches the number of ticks of the division.

If the decision result in the step S1408 is affirmative, that is, if the value of the tick counter in the division matches the number of ticks of the division, that is, if it is detected that it is a division of the division, step S141 is performed.
The process proceeds to 0, and it is determined whether the arranger ending flag is “1”.

If the decision result in the step S1410 is affirmative, that is, if the arranger ending flag is “1”, a division break is detected during the ending pattern reproduction, that is, reproduction is performed until the end of the ending pattern. Therefore, the flow advances to step S1412 to set both the arranger start flag and the arranger ending flag to "0", and returns to the tick event processing routine.

Here, Arranger Start
Since both the flag and the arranger ending flag become "0", the arranger 12b is stopped.

On the other hand, if the decision result in the step S1408 is negative, that is, if the value of the tick counter in the division is different from the number of ticks of the division, the process returns to the tick event processing routine without performing any processing.

If the result of the determination in step S1410 is negative, that is, if the arranger ending flag is "0", the process returns to the tick event processing routine without performing any processing.

Next, the composer reproduction processing routine in step S1222 will be described in detail with reference to the flowchart shown in FIG.

In this composer reproduction processing routine, first, in step S1502, song data is read.

Next, in step S1504, it is determined whether or not the song data read in step S1502 is EOD, which is data indicating the end of the song data.

If the judgment result in the step S1504 is affirmative, that is, if the song data read in the step S1502 is EOD, the flow advances to a step S1506.
Set the composer start flag to "0".

When the processing in step S1506 ends,
Proceed to step S1508, and arranger start
It is determined whether the flag is “1”.

If the result of the determination in step S1508 is affirmative, that is, if the arranger start flag is "1", the flow advances to step S1510 to determine whether or not the arranger ending flag is "0". .

If the decision result in the step S1510 is affirmative, that is, if the arranger ending flag is "0", it means that the arranger 12b is reproducing the normal pattern, so the flow advances to the step S1512 to start the arranger start. After setting the flag to "0", the composer reproduction processing routine is terminated and the process returns to the tick event processing routine.

On the other hand, if the decision result in the step S1508 is negative, that is, if the arranger start flag is "0", the composer reproduction processing routine is terminated without performing any processing, and the tick event processing routine is terminated. Return to

If the result of the determination in step S1510 is negative, that is, if the arranger ending flag is "1", it means that the ending pattern is being reproduced by the arranger 12b, so that no processing is performed. The composer reproduction processing routine ends without returning to the tick event processing routine.

[0192] The result of the determination in step S1504 is negative, that is, the song read out in step S1502.
If the data is not EOD, the process advances to step S1514 to determine whether the song data read in step S1502 is arranger start information.

[0193] If the decision result in the step S1514 is affirmative, that is, if the song data read out in the step S1502 is arranger start information, the flow advances to step S1516, and the arranger start flag is "0". It is determined whether or not.

If the decision result in the step S1516 is affirmative, that is, if the arranger start flag is "0", it means that the arranger 12b is in the stopped state, and the flow advances to the step S1518 to set the arranger start flag. After setting the value to "1", the composer reproduction processing routine is terminated and the process returns to the tick event processing routine.

On the other hand, if the decision result in the step S1516 is negative, that is, if the arranger start flag is "1", it means that the arranger 12b is already being executed, so that the composer is executed without any processing. The reproduction processing routine ends, and the process returns to the tick event processing routine.

If the result of the determination in step S1514 is negative, ie, the song read out in step S1502,
If the data is not arranger start information (in this case, the read song data is EO
Not a D. ), The process proceeds to step S1520, and after the read song data is transmitted to the sound source 20,
The composer reproduction processing routine ends, and the process returns to the tick event processing routine.

Hereinafter, an operation example of the present invention will be described. First, the "synchronous start process" will be described.

In the present electronic musical instrument, the composer 12
a during the playback of song data,
When the start of the playback of the arranger 12b is instructed by the start button 22d, the arranger 12b starts in synchronization with a specific timing during the performance of the composer 12a, and the process at this time is called a synchronous start process. Hereinafter, the operation procedure and operation of the synchronous start process will be sequentially described.

First, when the composer start button 22a is operated as the first operation after the power is turned on, the composer start processing is performed by the processing of step S204 of the main routine and steps S302 → S304 of the switch operation processing routine. Routine (Fig. 4)
Is executed.

In the composer start processing routine, the composer start flag is detected (step S402), and since this composer start flag is initialized to "0" (step S202), the composer start flag is set. Set the flag to “1” and initialize the tick event counter and the tick counter in division to “0” (step S404).

Since the composer recording preparation flag has been set to "0" by the initialization (step S202), the composer start processing routine ends without performing the subsequent processing.

If no switch operation is performed thereafter, a tick event processing routine (FIG. 1)
2) is performed (Step S204 → Step S20)
6).

In the tick event processing routine, the value of the tick counter in the division is set to "0" by initialization (step S404), so that the value of the tick counter in the division and the number of ticks in the timing register 1 are set. Does not match (step S1204), and since the arranger start flag has been set to "0" by initialization (step S202), the process proceeds to the next stage (step S1220).

At the next stage (step S1220), the composer start flag is detected. At this point, since the composer start flag is "1" at step S404, the composer reproduction processing routine (FIG. 15) ) (Step S122)
2) The song data is transmitted to the sound source (step S
1520), the tone generator 20 performs a performance based on the song data.

Next, as a second operation, the arranger
When the start button 22d is operated, the arranger start processing routine (FIG. 6) is executed by the processing of step S204 of the main routine and step S310 → step S312 of the switch operation processing routine.

In the arranger start processing routine, the arranger start flag is detected (step S602), and since the arranger start flag is initialized to "0" (step S202), the composer start is performed. Detect a flag (step S604).

Since the composer start flag has been set to "1" by the above-described first operation, the arranger start preparation flag is set to "1" (step S608), and the arranger start processing routine is executed. finish.

Therefore, at this point, the arranger start flag has not become "1".

If no switch operation is performed thereafter, a tick event processing routine (FIG. 1)
2) is performed (Step S204 → Step S20)
6).

At the time when the tick event processing routine is executed, the composer start flag is set to "1" and the arranger start flag is set to "0".
Since the arranger start preparation flag is "1", in the tick event processing routine, only the composer is reproduced until the timing stored in the timing register 1 is detected ( In step S1222), when the stored timing is detected, the arranger start flag is set to "1".
Then, the arranger start preparation flag becomes “0” (step S1206 → step S1208).

Therefore, the next step (step S1210)
Since the arranger start flag is "1", the arranger reproduction processing routine is executed (step S1210 → step S121).
8) The style data is transmitted to the sound source,
Performs an accompaniment based on the style data.

Thus, the timing register 1
Until the timing stored in the timing register 1 is detected, only the composer 12a is reproduced, and when the timing stored in the timing register 1 is detected, the composer 12a is reproduced.
2b is reproduced.

Therefore, in this electronic musical instrument, when the composer 12a instructs the reproduction start of the arranger 12b by the arranger start button 22d while the song data is being reproduced, the arranger 12b
Performs a synchronous start process that starts in synchronization with a specific timing during performance of the composer 12a.

Next, an operation procedure and an operation of an ending process for ending the performance of the composer 12a and the accompaniment of the arranger 12b will be sequentially described.

First, when the a-ending button 22f is operated as a third operation following the above-described first operation and second operation, step S204 of the main routine and step S31 of the switch operation processing routine are performed.
8 → By the process of step S320, an arranger / ending process routine (FIG. 8) is executed.

In the arranger ending processing routine, the arranger ending flag is detected (step S802), and since the arranger ending flag is "0" (step S202),
An arranger start flag is detected, and since the arranger start flag is "1" in step S1208, the arranger ending flag is set to "1" (step S804 → step S806).

If no switch operation is performed thereafter, a tick event processing routine (FIG. 1)
2) is performed (Step S204 → Step S20)
6).

At the time when the tick event processing routine is executed, since the arranger start flag is already "1", the arranger reproduction processing routine (FIG. 14) is executed.

In the arranger reproduction processing routine, an arranger ending flag is detected (step S1402), and since the arranger ending flag is "1", an ending pattern reproduction processing (step S1406) is performed.

If the value of the tick counter in the division matches the number of division ticks, that is, if it is detected that the division is a division,
An arranger ending flag is detected (step S1408 → step S1410), and the arranger ending flag is detected.
Since the ending flag is "1", the division of the division was detected during the reproduction of the ending pattern, that is, since the ending pattern was reproduced to the end, the arranger start flag and the arranger ending The flags are both set to "0", and the arranger 12b is stopped (step S1412).

On the other hand, in the composer reproduction processing routine (FIG. 15), the song data is read (step S1502), and if the song data read in step S1502 is EOD, the composer start flag is set to "0". (Step S1504 → Step S1506).

Then, an arranger start flag is detected (step S1508). If the arranger start flag is "1", an arranger ending flag is detected (step S1510), and the arranger ending flag is set. If "1",
Since the arranger 12b is reproducing the ending pattern, the composer reproduction processing routine ends without performing any subsequent processing.

That is, if the composer reads EOD before the arranger 12b finishes reproducing the ending pattern, the arranger start flag is "1" and the arranger ending flag is "1". , The arranger start flag is not set to "0". That is, the arranger 12b is not stopped.

Thereafter, when the end of the ending pattern of the arranger 12b is detected, the arranger start flag is set to "0". That is, at this point, the arranger 12b stops.

As described above, if the composer 12a reads the EOD before the end of the ending pattern, the composer 12a reads the EOD before the ending of the ending pattern.
Is not stopped, and when the end of the ending pattern of the arranger 12b is detected thereafter, the arranger 12b stops.

Therefore, according to the above-described embodiment, if the start of the play of the arranger 12b is instructed by operating the arranger start button 22d during the play of the composer 12a, the arranger 12b specifies the play of the composer 12a. (The beginning of a bar or a specific beat in a bar) starts playback.

That is, the composer 12a and the arranger 12b are reproduced synchronously at a desired timing.

When the composer 12a finishes reproducing all the song data, the arranger 12b stops immediately if the normal pattern is being played, and ends if the ending pattern is being played. Do not stop until you do.

That is, even if the playback of the composer 12a ends first, the arranger 12b is always played back to the end of the ending pattern.

Next, as another embodiment, arranger start information is previously stored in the song data at each specific timing, and the composer 12a is stopped by the composer stop button 22b during reproduction by the composer 12a. Is instructed, the composer 12a
The following describes an embodiment in which the arranger 12b stops immediately, but when the composer 12a starts reproducing again, the arranger automatically restarts the reproduction by the arranger start information that appears after the composer 12a starts reproducing.

In this embodiment, the composer 12a is operated by operating the composer start button 22a.
Since the arranger 12b starts automatically at the timing when the arranger start information is stored, without having to operate the arranger start button 22d again after the instruction to start the reproduction, the complicated operation is eliminated. Thus, the effect that the operability is improved can be obtained.

In the following, as described above, Arranger 1
The operation and the operation when the arranger 12b is automatically started again by storing the arranger start information in the song data when the 2b is stopped will be sequentially described.

First, the operation and operation when storing arranger start information in song data will be described.

As a first operation, when the composer recording button 22c is operated, step S of the main routine is executed.
204, Step S322 of the switch operation processing routine
→ By the processing of step S324, a composer recording preparation processing routine (FIG. 9) is executed.

In the composer recording preparation routine, the composer start flag is detected (step S902), and since the composer start flag is initialized to "0" (step S202), the arranger start is performed. -A flag is detected (step S904). This arranger start
Since the flag has been set to "0" by the initialization (step S202), the process proceeds to step S9 without performing any processing.
Proceed to 08.

Next, a composer recording preparation flag is detected (step S908), and since this composer recording preparation flag is "0" (step S202), it is set to "1" (step S910).

Next, as a second operation, the composer
When the start button 22a is operated, the composer start processing routine (FIG. 4) is executed by the processing of step S204 of the main routine and steps S302 → S304 of the switch operation processing routine.

In the composer start process,
Since the composer start flag is "0",
After setting the composer start flag to “1” and initializing the tick event counter and the tick counter in division to “0” (step S402 → step S404), the composer recording preparation flag is detected (step S406). Since the composer recording preparation flag is "1", the composer recording flag is set to "1" and the composer recording preparation flag is set to "0" (step S408).

Further, as the third operation, when the arranger start button 22d is operated, the arranger start processing routine (FIG. 6) is executed by the processing of step S204 of the main routine and steps S310 → S312 of the switch operation processing routine. ) Is executed.

In the arranger start processing routine, first, an arranger start flag is detected (step S602). Since the arranger start flag has been initialized to "0" (step S20)
2), a composer start flag is detected (step S604).

At this point, since the composer start flag is set to "1" by the operation of the second operator, the arranger start preparation flag is set to "1" (step S608).

If no switch operation is performed thereafter, a tick event processing routine (FIG. 1)
2) is performed (Step S204 → Step S20)
6).

In the tick event processing routine, when the tick counter in the division matches the number of ticks in the timing register 1, the arranger start preparation flag is set to "1" at this point. The start flag is set to “1” and the arranger start preparation flag is set to “0” (step S1204 → step S120)
6 → Step S1208).

Then, an arranger start flag is detected (step S1210). Here, in step S1208, the arranger
Since the start flag is “1”, the tick counter in the division reads the timing register 2
, The composer recording flag is detected (step S1212 → step S121).
4).

Here, since the composer recording flag is "1" in step S408, the arranger start information is stored in the song data (step S1216), and the arranger reproduction processing routine (FIG. 14) is executed (FIG. 14). Step S1218).

Next, a composer start flag is detected (step S1220). Since the composer start flag is "1" in step S404, the composer reproduction processing routine (FIG. 15) is executed. Is performed (step S1222).

Thereafter, the arranger reproduction processing routine and the composer reproduction processing routine are executed as described above.
It is executed repeatedly.

When the tick event processing routine detects that the tick counter in the division matches the number of ticks in the timing register 2, the composer recording flag is "1". Store start information in song data (step S1212 → step S121)
4 → Step S1216). In this way, the arranger start information is stored in the song data for each number of ticks in the timing register 2.

Further, as a fourth operation, when the composer stop button 22b is operated, the composer stop processing routine (FIG. 5) is executed by the processing of step S204 of the main routine and steps S306 → S308 of the switch operation processing routine. ) Is executed.

In the composer stop processing routine, first, a composer start flag is detected (step S502). Since the composer start flag is "1", that is, the composer 12a is executing, Composer 12a with "0"
Is stopped (step S504).

Next, the composer recording flag is detected (step S506). Since the composer recording flag is "1", that is, the composer 12a is recording, the recording is stopped by setting the composer recording flag to "0". (Step S508), and then proceeds to detection of the arranger start flag (step S51).
0).

The arranger start flag is detected (step S510). Since the arranger start flag is "1", that is, the arranger 12b is being executed, the arranger start flag is detected.
The flag is set to "0" to stop the arranger 12b (step S512), and the composer stop processing routine ends.

The recording operation is completed as described above.

Next, the operation and operation for reproducing the song data thus recorded will be described below.

First, as a first operation, a composer
When the start button 22a is operated, the composer start processing routine (FIG. 4) is executed by the processing of step S204 of the main routine and steps S302 → S304 of the switch operation processing routine.

In the composer start processing,
The composer start flag is set to "1", and the tick event counter and the tick counter in the division are initialized to "0" (step S).
402 → Step S404).

If no switch operation is performed thereafter, a tick event processing routine (FIG. 1)
2) is performed (Step S204 → Step S20)
6).

Since the composer start flag is "1" in the tick event processing routine, the composer reproduction processing routine (FIG. 15) is executed (step S1220 → step S1222).

In the composer reproduction processing routine, the song data is read out (step S150).
2) If the data is arranger start information (step S1514), the arranger start
A flag is detected (step S1516), and this is set to "0".
Therefore, since the arranger 12b is stopped, the arranger start flag is set to "1" (step S1518).

That is, the song data includes a timing
Since the arranger start information is repeatedly recorded for each timing of the register 2, the composer 12a
When the reproduction of the file starts and the arranger start information is read, the arranger 12b starts.

Alternatively, if the arranger start button 22d is operated before reading the arranger start information stored in the song data, the arranger 12b is operated at the timing described in the above embodiment.
Starts.

Next, as a second operation, the composer
When the stop button 22b is operated, the composer stop processing routine (FIG. 5) is executed by the processing of step S204 of the main routine and steps S306 → S308 of the switch operation processing routine.

In the composer stop processing,
The composer start flag is set to “0” (step S506), and the arranger start flag is set.
The flag is set to "0" (step S512), and the composer 12a and the arranger 12b stop.

Further, as a third operation, when the composer start button 22a is operated, the composer start processing routine (FIG. 10) is executed again by the processing of step S204 of the main routine and steps S302 → S304 of the switch operation processing routine. 4) is executed, and the song data is read out in the same manner as described above (step S1502).

At this time, the song data is read from the next data read earlier. Here, the arranger start information is repeatedly recorded in the song data at each timing of the timing register 2.
When it comes to the timing of the next timing register 2,
The arranger 12b starts by reading the arranger start information.

In this way, when the arranger 12b stops, it automatically starts at each timing of the timing register 2.
