A Touch Sensitive Keyboard for Electronic Music
An interface system has been developed allowing for connection of a concert grand piano action and keyboard to a digital electronic music synthesizer.

These detectors are scanned by a microcomputer and information about the velocity and sustained duration of each key depressed is passed on to the synthesizer.
