Abstract
PURPOSE: To generate a musical sound to which an acoustic effect such as a vibrate effect is annexed by modulating the delay time of waveform data. CONSTITUTION: An waveform memory 30 corresponds to n tone colors and stores respective waveform data specified by a tone color selection signal TSW outputted from a switch circuit 12 and an interpolation circuit 40 is provided with an waveform data correction means consisting of a shift register 41 for circularly storing waveform data, a subtractor 42, a gate circuit 43, a multiplier 44, and an adder 45. Modulated waveform data generated from a generator 60 are added to frequency division rate data outputted from a memory 58 by an adder 52 and an output from a variable frequency divider 51 has frequency obtained by modulating m times the frequency of tone height by a low frequency signal based upon the added output. The sampling data circulation storing time of the register 41 is modulated in accordance with the frequency division output and a vibrate effect is annexed to a musical sound signal outputted from a sound system 74.
