ABSTRACT:
A sequencer unit of electronic musical instrument including a plurality of sequencers each storing specific performance data which are generated by operating a keyboard in advance. In the case where an automatic performance is played based on first performance data of selected one sequencer and then second performance data of another sequencer are selected, the first performance data are smoothly changed over to the second performance data and then the automatic performance is played based on the second performance data at a desirable timing which can be arbitrarily determined. Even when the ending timing of performance data to be written in the sequencer does not match with the end of bar, the length of performance data read from the sequencer can be easily adjusted to predetermined bars. Further, it is possible to easily adjust a break period in which the automatic performance is broken so that keyboard performance can be played.
