Abstract
An electronic musical instrument includes a keyboard having a plurality of keys, each depressed key being identified by a uniquely developed multibit code. Each of a plurality of tone generators, substantially less in number than the number of keys characterizing the keyboard, is operable in response to each of the multibit codes for producing a tone signal having a frequency corresponding to the pitch of the associated depressed key. Each depressed key is assigned for playing through one of the tone generators by a control circuit, the control circuit being responsive to the condition wherein all of the tone generators have been assigned to previously played keys for assigning a newly played key for playing through the tone generator which was assigned to the oldest released one of the previously played keys.
