ABSTRACT:
There is provided a first waveform generator which repeatedly generates a first waveform having a relatively short period in response to a first constant parameter, a second waveform generator responsive to a second constant parameter for generating a second waveform having a longer period than the repeatedly generated waveform and gradually approaches to zero in the later half of its period, a multiplier for multiplying the first waveform and the second waveform to form a musical tone waveform element, and means for resetting the waveform generating operations of the first and second waveform generator at a period corresponding to the tone pitch of a depressed key. Sequential alignment of the musical tone waveform elements constitutes a musical tone waveform having a tone frequency determined by the resetting period. The changes in the parameters cause changes in the tone color.
