If it is determined, the process proceeds to S1106 to stop the composer (automatic performance means) and the arranger (automatic accompaniment means).
[0050]
On the other hand, when the end of playback is not instructed, the progress of music is displayed in units of two bars on the display screens shown in FIGS. 6 to 7, so that the cumulative value of the tick counter is the number of ticks for two bars. When the number becomes a multiple of (S1108), the display screen is updated based on the display information of the arranger control information shown in FIG. 4 (S1110).
[0051]
Then, it is determined whether or not the read event is arranger control information (S1112). If the read event is arranger control information, the process proceeds to S116. On the other hand, the read event is not the arranger control information but a note. If it is information or timbre change information, the process proceeds to S1114 and is output to the sound source 24.
[0052]
In the process of S1116, it is determined whether or not the arranger control information stored in the buffer in the processes of S906 and S908 matches the read event. If the two match, the read event is set in the arranger (S1118), and if the composer and arranger are stopped, playback is resumed (S1120 → S1122). If not, the process is continued. (S1120 → S1102).
[0053]
On the other hand, if the read event does not match the arranger control information (including code information) stored in the buffer in the processing of S906 and S908, the key pressing guide display screen and the arranger operation guide display screen are displayed. The user's operation is guided (S1124), and if the composer and the arranger are in operation, they are temporarily stopped (S1126 → S1128), and if not in operation, the process is continued (S1126 → S1102).
