ABSTRACT:
A keyboard system for an electronic musical instrument of the keyboard type, such as a synthesizer, electronic piano, organ or controller keyboard. The keyboard includes an electromechanical key actuation and sensing element that in combination with electronic processing allows the performer to adjust both tactile and tone control parameters associated with keyboard touch response. The tactile response can be tuned over a broad range and is capable of simulating a light organ touch, heavier "piano key feel" or stiff percussive action. Since any of these features can be selected and adjusted while the performer is playing the keyboard, the keyboard system also has a desirable "real time" capability that does not interfere with musical performance.
