Abstract

PURPOSE: To control amplitude by an amplitude controlling D/A converter and to generate a musical sound by computing data for plural amplitude controlling memories by a computing element, determining an amplitude value by the amplitude controlling D/A converter and applying amplitude information to a waveform generator. CONSTITUTION: The computing element 3 computes the contents of an envelope amplitude memory 1 for applying timewise amplitude information and a sound pressure adjusting amplitude memory 2 for adjusting sound pressure in the whole sound at each time and determines the digital data of the amplitude value of a waveform at the time. An amplitude D/A converter 4 converts the obtained dital data into a practical analog amplitude value and outputs the analog value, and a waveform generator 5 receives the amplitude data and outputs a final musical sound output waveform. Even in a musical sound generator including plural amplitude controlling memories having respectively different purposes for a musical sound, the number of amplitude controlling 0/A converters can be set up to less than the number of musical sounds.
