Electronic percussion device for generating a percussion waveform using shock strength and vibration of a batter head

摘要

Changes in vibratory position of a batter head of a percussion are detected to output a decay vibration waveform by a detector. A tone source controller sequentially generates a plurality of tone source control codes on the basis of the decay vibration waveform data along time lapse. A tone source circuit controls a reading operation of digital waveform data of percussion tones stored in a waveform memory, and modification of readout data on the basis of the tone source control codes, to generate a tone waveform signal.
