PURPOSE: To improve the flexibility of an effective sound by mixing plural output sounds based upon waveform data generated by accessing a prescribed address selected from plural sound generation channels at a prescribed speech and outputting a prescribed output sound. CONSTITUTION: Respective sound generation channels Ch1 to Ch6 include respective waveform registers 61 to 66 . The registers 6, to 66 have waveform data corresponding to prescribed addresses and an output sound with prescribed frequency can be obtained by continuously accessing a prescribed address by the prescribed number of times at a prescribed speed, i.e., the prescribed frequency. Sounds outputted from plural channels Ch1 to Ch6 are mixed and a prescribed sound is outputted by the mixing. When necessary, the selection of a musical sound and noise is controlled and the frequency modulation of an output sound is also controlled. Consequently rhythm sound effective sound or an effective sound vibrate can be flexibly generated. |
