ABSTRACT:
A musical chord system includes a pedal console comprising a plurality of foot-actuated pedal switches, a chord selection switch console comprising a plurality of chord selection switches associated with said pedal switches, and diode matrix logic means interconnecting the chord selection switches with the tone generating circuitry of a conventional electronic musical instrument such as an electric organ whereby chords are sounded upon depression of the foot pedals. By adjustment of the corresponding chord selection switch, each foot pedal can be set to produce any desired one of a multiplicity of possible chords. Switches are also provided to permit the chords to be sounded on different octaves and keyboards or combinations thereof. A priority interconnect circuit prevents more than one chord from being played when two pedals are simultaneously depressed. A lower musical keyboard sustaining circuit permits the upper manual keyboard to be pulsed with alternating partial and full depression of a pedal.
