ABSTRACT:
An electronic musical instrument can execute a musical performance with two timbres mixed together by operating a single key, for example. Of the two timbres, a master timbre is set in normal mode and is stored in a first memory, while a slave timbre is selected in tone mix mode and is stored in a second memory. Each timbre can be altered as desired. To alter the master timbre, timbre switches are operated after the mode is temporarily changed to normal mode. To alter the slave timbre, the timbre switches are operated in tone mix mode. When the tone mix mode is set, this electronic musical instrument can permit a player to easily alter tone parameters such as the volume, pitch and attack delay time of each timbre.
