A sound source for an electronic percussion instrument and sound production control method thereof are provided. An electronic drum sound source device performs a weighting operation on four pieces of waveform information (pitch envelope, amplitude envelope, start phase) stored in a waveform table according to the beating conditions (hitting point position, velocity) based on the output from a struck sensor of an electronic drum pad. 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 whereon the weighting operation was performed. The sine wave is not synthesized with waveform data other than the residual waveform data, and thus consistent musical sounds with no phase interference can be reproduced.

Sound source for electronic percussion instrument and sound production control method thereof

An electronic percussion instrument that detects vibrations due to a hit and outputs a corresponding signal where the head of the instrument is held in place independent of a rim part. The independence stops vibrations originating from a hit of the rim from traveling to the head and interfering with the proper signal detection of hits to the head part.

Electronic percussion instrument

An object of the present invention is to provide a percussion detecting apparatus, which is excellent in percussion feeling, and the percussion sounds of which are very small, in electronic percussion instrumental system. The percussion detecting apparatus is provided with a head prepared from a net-like raw material composed of a first net and a second net, the net-like raw material being obtained by such a manner that both the nets having been woven in accordance with plane weaving manner wherein the longitudinal and transverse fibers cross at right angles are laminated in such a way that the weave pattern directions thereof intersect obliquely with each other; and a head sensor which is in contact with the center position of the under side in the head and detects percussion with respect to the head as electric signal.

Electronic percussion instrumental system and percussion detecting apparatus therein

The present invention is intended to provide an electronic cymbal having improved accuracy for detecting a striking force and a striking position without hampering a striking sensation and an appearance. A piezoelectric sensorand a cup portion sheet sensorprovided on a portion of a cup portion formed into a dome shape at a center of a coveron a first framehaving the coverformed out of a soft material, the coverspreading to contact with an upper surface of the first frame, and an edge upper portion sheet sensorand an edge lower portion sheet sensorprovided on an outer peripheral edge portionformed to be lowered by a step are provided, and a center of a second frameis supported by a cymbal stand (shaft)penetrating an opening portion at a center of the first frame
