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