ABSTRACT:
The present invention relates to an automatic performance apparatus of an electronic musical instrument for activating and deactivating an automatic performance for each musical part such as melody tone, accompaniment tone, or rhythm tone. The first performance data memory stores an instruction signal which instructs the second reading circuit to start and stop reading performance data stored in the second performance data memory, so that the reading of the performance data stored in the second performance data memory can automatically start and stop in accordance with the progressing of the reading based on the performance data stored in the first performance data memory. Both performance data stored in the first performance data memory and in the second performance data memory are read by respective reading circuits, so that it is possible to selectively start and stop reading the performance data stored in both the first performance data memory and the second performance data memory.
