PURPOSE:To continuously obtain a musical sound which is easily controlled and has a natural feeling and nonmonotonousess. CONSTITUTION:The musical sound synthesis device which has a loop circuit 2 including a delay circuit 21 and an exciting circuit which inputs an excitation signal to the loop circuit employs an excitation system which is not limited to oscillation conditions. Further, the exciting circuit consists of a waveform generating circuit 1, a noise generating circuit 3, and a modulation control circuit 4 which modulates the output waveform of the waveform generating circuit according to the noise output of the noise generating circuit. In another way, plural excitation waveforms are switched in order with time for one kind of timbre. |
