Title:
SOUND SOURCE FOR ELECTRONIC PERCUSSION INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2018/055892
Kind Code:
A1
Abstract:
[Problem] To provide a sound source for an electronic percussion instrument capable of reproducing consistent sounds of a percussion instrument with no phase interference while capable of creating a smooth change in volume and tone color with a change in beating conditions. [Solution] An electronic drum sound source device 2 performs a weighting operation on four pieces of waveform information (pitch envelope, amplitude envelope, start phase) stored in a waveform table 22a according to the beating conditions (hit point position, velocity) based on the output from a beat sensor 31 of an electronic drum pad 3. The electronic drum sound source device creates a sine wave on the basis of the waveform information whereon the weighting operation was performed, and generates musical sounds (sounds of percussion instrument) by synthesizing the sine wave with the waveforms of residual waveform data RW1-RW9 whereon the weighting operation was performed. The sine wave is not synthesized with waveform data other than the residual waveform data RW1-RW9, and thus consistent musical sounds with no phase interference can be reproduced. A smooth change in volume and tone color of the musical sounds with the change in beating conditions can also be created.
