PROBLEM TO BE SOLVED: To make it possible to generate sound even if a plurality of sound are instructed at the same time. SOLUTION: When performance information is generated, an operation part 2 calculates and generates waveform data corresponding to the performance information by the processing during the performance, and outputs to a buffer 8 and also stores the data in a waveform memory 4. When two or more sound the instructed at the same time, only operable sound are calculated and generated. And, in the reproducing process, the waveform data which have already been calculated and generated are read from the waveform memory 4, and also the waveform data which were not calculated nor generated are operated by the operation part 2 for being outputted to the buffer 8. Thus, it becomes possible to generate the instructed plural sound at the same time at the time of reproducing. |
