Latest Patents
James B. Murphy holds a patent for a "Multiple voice electric piano and method." This electric piano features a complete player-actuated piano voice, where harmonics are primarily controlled by a tuning fork struck by the piano key. Additionally, the instrument is equipped with an electronically generated voice, allowing for harmonics that are electronically produced. To facilitate the simultaneous play of both voices when a single piano key is struck, the amplitude envelope of the electromechanically generated piano voice is applied to the electronically generated voice. This voice is gated and amplitude modulated to ensure it is heard in precise synchronization with the note produced by the player. The design also incorporates modulating and gating diodes in oppositely poled feedback paths of an operational amplifier, extending the linearity of modulation to low piano voice amplitudes.
