摘要：This invention relates to a process and means for providing a keyboard ofelectronic musical instruments with dynamics control. Each key (20), movable betweentwo extreme positions defining two possible states, shifts a mass (23) which can movealong a path, defined by a guide. The displacement speed of said mass (23) between twopredetermined sights (25, 27) is closely related to the sound intensity from the
instrument. Said speed is suitably transduced to cause an output voltage regulating thesound intensity emitted from the frequency and envelope generator device.
