Abstract:
1. An electronic sound generation device, comprising: a waveform memory storing waveform data; a digital signal processing circuit for starting, upon receipt of a start signal for starting arithmetic processing, predetermined arithmetic processing based on sound parameters and waveform data supplied from said waveform memory, outputting an in-operation signal indicating that said digital signal processing circuit is in operation during said arithmetic processing, and outputting resultant data of said arithmetic processing when said arithmetic processing is completed; a sampling signal generation circuit for periodically outputting a sampling signal with a constant period; a synchronized ON/OFF circuit receiving said periodic sampling signal and said in-operation signal, said ON/OFF circuit adapted to supply said digital signal processing circuit with a start signal for starting next arithmetic processing in synchronism with said sampling signal in the event that said predetermined arithmetic processing has been completed at the time said sampling signal is received but otherwise supply said start signal after said predetermined arithmetic processing is completed; and an arithmetic result output circuit for holding said resultant data of arithmetic processing supplied from said digital signal processing circuit and for outputting said resultant data as a sound data in synchronism with said sampling signal.
