Abstract
An electronic musical instrument producing a music having plural performance parts includes a generation channel unit including plural tone generation channels, a tone generation number designating unit, and a tone generation channel assigning unit. Each tone generation channel generates a tone of the music. The tone generation number designating unit designates a maximum simultaneous tone generation number to be given to each of the plural performance parts. The tone generation channel assigning unit assigns each of the plural performance parts to one or more available tone generation channels. The number of available tone generation channels is equal to the corresponding one of the designated maximum simultaneous tone generation numbers.
