First, the case where the performance data is a chord / rest and the process proceeds to step 204 will be described. Step 204
In, the operation of the rhythm counter for reading the rhythm pattern from the rhythm pattern memory 9 is started, the rhythm run flag is set, a chord is sounded from the speaker 13, and the beat length data is set in the beat length counter. When this series of processes is completed, the process returns to step 200, but since the rhythm run flag has been set, the operation is repeated in steps 201 and 202. Also, although not shown in this flow chart, when the rhythm run flag is set, an interrupt occurs at every quarter note interval,
The processing operation is the automatic cursor processing (interruption) shown in FIG.
The procedure moves to the routine (hereinafter referred to as "interrupt routine").

In this interrupt routine, the beat length counter counts, and when the counting is completed, the same processing operation as the routine of the automatic cursor processing shown in FIG. 15 is performed. When an interrupt occurs in the auto cursor processing tail routine, the processing operation is step 21 of the interrupt routine.
Move to 0. In step 210, the beat length counter is 1
Just count down.

Next, in step 211, it is judged whether or not the content of the beat length counter is "0". If it is not "0", the process returns to the routine of the automatic cursor processing shown in FIG. Proceed to 212. In this way, the processing operation goes back and forth between the automatic cursor processing routine and the interrupt routine until the beat length counter becomes “0”. The operation when the beat length counter becomes “0” will be described later. Next, the processing operation when it is determined that the performance data at the address pointer position is registration data in step 203 of the routine of the automatic cursor processing shown in FIG. 15 will be described. In this case, the processing operation proceeds to step 205. Step 20
5, the registration data is set on the operation panel A, and the process proceeds to step 206. In step 206,
The address pointer is incremented by 1, and the process returns to step 200.

Next, when it is determined in step 203 that the performance data at the address pointer position is a repetitive symbol, the processing operation proceeds to step 206, the address pointer is incremented by 1, and the operation returns to step 200. Next step 2
If it is determined at 03 that the performance data at the address pointer position is the end / reset, the processing operation of this routine ends. That is, step 66 shown in FIG.
Return to. Next, step 2 of the interrupt routine shown in FIG.
The processing operation when the beat length counter becomes "0" in 11 will be described. In this case, the processing operation proceeds from step 211 to step 212. In step 212, the address pointer is advanced by 1 to read the performance data from the performance data memory 8 and display it.

Next, at step 213, the contents of the performance data at the address pointer position are judged. If the performance data is a chord / rest, the process proceeds to step 214, if it is an end / reset, the process proceeds to step 215, if it is the registration data, the process proceeds to step 216, and if it is a repeat symbol, the process returns to step 212. First, the case where the performance data is a chord / rest will be described. In this case, in step 214,
The chord is sounded from the speaker 13, the beat length data is set in the beat length counter, and the process returns to the routine of the automatic cursor processing shown in FIG.

Next, when the performance data is the end / reset,
In step 215, the operation of the rhythm counter is stopped, the rhythm run flag is reset, and the generation of chords is stopped. In this case, the operation of the automatic cursor process is also completed, and the process returns to step 66 of the REC process routine shown in FIG. If the performance data is registration data, the registration data is set on the operation panel A in step 216, and the process returns to step 212. If the performance data is a repeat symbol, no processing operation is performed and the process immediately returns to step 212.

Next, in step 201 of the automatic cursor processing routine shown in FIG. 15, if it is determined that the rhythm start / stop switch 35 is off, the processing operation proceeds to step 207. At step 207, the performance data at the address pointer position is read out, displayed and sounded, and the routine proceeds to step 208. In step 208,
The rhythm counter is stopped, the rhythm run flag is reset, the chord is stopped, and this processing routine ends. The above is all of the automatic cursor processing operation shown in FIGS.

EDIT Processing Routine (FIG. 7) Next, the editing processing routine will be described with reference to FIG.
As shown in FIG. 5, when the recording switch 22 is off and the editing switch 23 is on, this editing process is performed. First, in step 71, if the speaker 13 is producing a sound, the production of the sound is stopped and the editing light emitting diode is turned on.
The light emitting diode for song selection blinks and blinking guidance is performed.

Next, at step 72, if one of the music selection switches is turned on, the process proceeds to step 73. In step 73, the selected song selection light emitting diode is turned on and the other song selection light emitting diodes are turned off. Next, in step 74, the registration data from the registration data area 40 of the selected SONG number area is set in the operation panel A and the registration memory 7.

Next, at step 75, the address pointer is set to the position of the head data and the head data is read and displayed. The "display" means that if the read data is chord data, the chord is sounded, if it is the beat data, the light emitting diode in the corresponding beat switch is turned on, and if it is the symbol data, the corresponding symbol is displayed. Turn on the light emitting diode in the switch, and if it is the registration data, turn on the light emitting diode in the resist switch, and also turn on the light emitting diode in the corresponding resist number switch or resist cancel switch to the corresponding resist state of the operation panel. Set each control. Therefore, in the example of FIG. 4, since the rest data and the 4-beat data are read, the light emitting diode in the beat length switch 27a is turned on.

Next, in step 76, if the edit switch 23 is on and the reproduction switch 21 is off, the process proceeds to step 77. If the edit switch 23 is off or the reproduction switch 21 is on, the process proceeds to step 78. move on. In step 77, the same processing as step 67 shown in FIG. 6 described above is performed. For this process,
This will be described later with reference to FIGS. In step 78, the registration data in the registration memory 7 is loaded into the performance data memory 8 and rewritten. This is similar to step 68 described above.

Next, at step 79, the editing light emitting diode and the song selecting light emitting diode are turned off. If none of the music selection switches are turned on in step 72, the process proceeds to step 80. If the predetermined time has not elapsed in step 80, step 72
Return to. If the predetermined time has elapsed, the process proceeds to step 79. The above is all of the processing operation of the EDIT processing routine.
