Abstract: PURPOSE:To apply reverberation to musical tones with simple circuit constitution by generating time musical tone waveforms with prescribed time differences from each of plural sub-channels and controlling the sound production to apply the reverberation effect. CONSTITUTION:Key on/key off signals and key code data as pitch assigning information of the musical tones are applied to a CPU 2 in accordance with the operation of a keyboard 1. The control signal from a switch part 3 consisting of a timbre selecting switch 4 and a reverberation applying switch 5, etc., is applied to the CPU 2. The CPU 2 outputs the key on signal and control signal read therein in accordance with the program read out of a ROM 7 generates the musical tone waveform data to a sound source system 7.
