Description

ABSTRACT:
An electronic musical instrument having a key-depression-detecting circuit for detecting a depressed key on a keyboard and for generating tone-pitch data corresponding to the depressed key, a tone-color-designating circuit for sequentially designating a desired tone color among a plurality of tone colors, a tone-color-data-storing circuit for storing tone-color data associated with the tone colors sequentially designated by the tone-color-designating circuit, an ensemble-tone-designating circuit for designating a predetermined number of tone colors among the most recently designated tone-color data stored in the tone-color-data-storing circuit; and a musical-tone-signal-generating circuit for generating a plurality of musical-tone signals in a parallel fashion, each of the musical-tone signals having a tone color corresponding to one of the tone colors designated by the ensemble-tone-designating circuit, and having a tone-pitch corresponding to the tone-pitch data generated by the key-depression-detecting circuit. The invention facilitates the selection of a desired combination of instrument sounds in an ensemble as well as changing the combination.
