PROBLEM TO BE SOLVED: To increase the number of sounds which can be generated at the same time without exceeding the permissible load on a CPU generating a software sound source. SOLUTION: A CPU 1 sets the maximum number of voice oscillators for respective voices and the maximum number of timbre oscillators for respective timbres and stores MIDI data inputted through a MIDI interface 8 in a memory 7. When the MIDI data are note-ON data for generating multiple musical sounds of different pitch at the same time, the oscillator of the lowest priority level of the voice is muted if the number of oscillators of the simultaneous sound generation of the voice exceeds the maximum number of voice oscillators and the oscillator of the lowest priority level of the timbre is muted if the number of oscillators of simultaneous sound generation of the timbre exceeds the maximum number of timbre oscillators. |
