ABSTRACT:
In a musical tone waveform generation apparatus for outputting musical tone signals generated by a software program at predetermined time intervals, sound source methods can be selected in units of tone generation channels. In the musical tone waveform generation apparatus, the sound source method or the tone color of a musical tone signal to be output is determined in accordance with performance data (pitch data, touch data, music part data, and the like). A musical tone signal is generated by CPU upon execution of a sound source processing program, associated with a modulation method stored in a memory. The generated musical tone signal is output at predetermined time intervals. As for sound source processing based on the modulation method, at least one operator processing, and algorithm processing for determining an input/output relationship among the operator processing operations are independently executed.
