ABSTRACT:
A tone synthesizer for generating a musical tone where harmonic content can be varied with time to produce unique sound effects. This is accomplished by generating waveform data in time sequence, delaying the waveform data by a time interval that is variable, and subtracting the delayed data from the waveform data to provide a modified sequence of waveform data which is then converted to an audio wave.
