摘要:
A system (1) used to reproduce the sound of a stringed instrument provided with hammers striking the strings is disclosed. The system comprises speed detection means coupled with each hammer to detect the percussion velocity on the string, a plurality of note modules receiving in input a signal representative of the hammer velocity and generating a force signal (F tot ) representative of the global partial components of the string vibration, and a soundboard-instrument body module (700) receiving in input said signal of the global partial components (F tot ) from each note module and generating two electrical signals (left, right) adapted to drive two electroacoustic transducers for sound emission.

The present invention consists in a method and electronic device used to reproduce the sound of church organ flue pipes, by taking advantage of the physical modeling technique of acoustic instruments; it being an audio-digital synthesis system based on digital signal processors, which contains a program of physical simulation of the generation of the sound of organ flue pipes.
摘要:
The present invention refers to a method used to automatically tune, thanks to the presence of a suitably designed electronic device, an electronic organ with the air organ pipes associated with it; it being provided, in particular, that the said operation is performed based on the tuning variations detected in real time on the air pipes based on parameters referring to the frequency of the emitted sound and to environmental temperature.
