ABSTRACT:
In an electronic musical instrument, there are provided a main musical tone generator for producing a main musical tone and a submusical tone generator for producing a submusical tone different from the main musical tone. The main musical tone generator has a plurality of tone production channels smaller than a total number of keys, the assignment of key information data corresponding to a depressed key to the tone production channel is changed according to a performance mode. The tone production channels and the key information data corresponding to depressed keys are divided into at least two groups respectively in the case of performance mode. One group of the tone production channels is assigned to one group of the tone production channels to produce the main musical tone for an automatic accompaniment, whereas another group of the key information data is assigned to the remaining group to produce the main musical tone for melody. In the submusical tone generator the key information data corresponding to the highest tone among the main musical tones for melody is used to produce the submusical tone.
