ABSTRACT:
An automatic performance apparatus provides a performance data memory including plural storing areas each capable of storing different performance data independently. The performance data can be selectively written in and read from each storing area. Based on the performance data read from each storing area, a musical tone signal for an automatic performance is generated independently. When the performance data memory includes two storing areas, the performance data concerning two tunes or two parts can be stored. One of two automatic performances based on the performance data can be selectively played. In addition, two automatic performances can be also player simultaneouly, wherein a predetermined delay time can be provided between two automatic performances. Further, predetermined kinds of rhythm patterns are pre-stored in a rhythm pattern memory in order to perform the desirable rhythm pattern as an accompaniment of the automatic performance.
