ABSTRACT:
A musical tone waveform signal generating apparatus in which a waveform signal is circulated to generate a musical tone waveform signal. The apparatus includes an excitation portion for mixing an excitation control signal with the waveform signal and for non-linearly converting the mixed waveform signal and a signal transmission portion coupled with the excitation portion to feed back the converted waveform signal to the excitation portion with delay of a predetermined time for causing on the converted waveform signal a resonance frequency corresponding with a pitch of a musical tone to be generated. In the excitation portion, the non-linear conversion of the mixed waveform signal is effected by a plurality of non-linear tables to generate various kinds of musical tone waveform signals, and the converted waveform signal is controlled by a tone color control signal to simulate the musical tone as a natural musical tone created by performance of a musical instrument such as a wind instrument, a brass-wind instrument, a stringed instrument or the like.
