Abstract
A controllable electronic musical instrument is disclosed as including tone pitch-assigning devices for assigning pitches to musical tones to be generated, manually operable members for producing detectable signals indicative of a touching of such members for operation thereof, a control message-producing device which is responsive to symbols from the manually operable members for producing musical tone-controlling messages that have magnitudes which automatically change in time, and a musical tone-generating device for generating musical tones based on musical tone-controlling messages produced by the control message-producing device, and based on a pitch assigned by the tone pitch-assigning devices. The tone pitch-assigning devices and the manually operable members may be provided as keys on a keyboard. The control message-producing device could include a microcomputer adapted to process data received from the assigning device and from the manually operable members to cause the tone generating device, which includes a speaker, to generate controlled musical tones.
