Title: Electronic musical instrument with 48-note keyboard - has digital programmed circuits to select the waveform of sounds produced
IPC: G10H7/12
Filed: 1982-12-16
Abstract: The sounds produced by the instrument can be radically altered by digital programming without the need for expensive analogue waveform shaping circuits.
