Abstract
Abstract Automatic performance data are stored by recording into a memory event data and timing data in correspondence to desired performance events. In recording the automatic performance data, predetermined data (for example, velocity data) contained in the event data is used as control information to modify the timing data, and the modified timing data is recorded into the memory. In reproducing the automatic performance data, the event and timing data are read out from the memory, and the performance events are then sequentially reproduced on the basis of the read-out data for effecting automatic performance. Thus, the reproduction timing of each performance event is finely controlled to modify by use of the control information, and this achieves automatic performance rich in expression. The fine control of the reproduction timing of each performance event may be done by, in stead of modifying the timing data during the recording, reading out unmodified timing data from the memory and modifying the read-out timing data on the basis of the control information during the reproduction.
