Abstract (en)
A data processing apparatus for an electronic musical instrument permits a microcomputer (31) to run a tone generating program for generating various types of musical tones. The microcomputer (31) calls the program by a timer interrupt signal and runs it for tone generation. The tone generation process is executed to generate a musical tone in synchronism with an envelope waveform process. Further, even if the time for sampling digital musical tones to be sent to a D/A converter is not constant, an analog signal free of distortion can be acquired.
