ABSTRACT:
A touch responsive sensor for an electronic keyboard musical instrument of a variable capacitor type, which comprises a pair of electrodes spaced apart from each other, and an intermediate electrode interposed between the pair of electrodes and separated from each of the pair of electrodes by a dielectric. The intermediate electrode is movable from near one of the pair of electrodes toward the other of the pair of electrodes in accordance with the movement of each playing key of the electronic musical instrument. Thus, in the course of a key depressing movement, first and second touch responsive controlling signals are derived from, respectively, between the one of the pair of electrodes and the intermediate electrode and between the other of the pair of electrodes and the intermediate electrode in accordance with the variation of capacitance produced therebetween.
