Claims

[Scope of Claim for Utility Model Registration] (1) A timbre information generation means for generating a plurality of timbre information for musical sound generation, and a musical sound generation and sound generation means for generating and emitting musical tones according to the timbre information from the timbre information generation means. a plurality of musical sound generation channels formed in the musical sound generation and sound emitting means; and channel number designation means for specifying the number of musical sound generation channels to be allocated to each of the tone information from the tone information generation means. and channel allocation means for allocating channels equal to the number of channels specified by the channel number specifying means to each of the timbre information. (2) The scope of the utility model registration claim characterized in that the channel number designation means is a means for designating the number of musical tone generation channels to be assigned to each piece of timbre information based on externally inputted channel number designation information. The electronic musical instrument according to item 1. (3) A utility model characterized in that the channel number designating means is a means for designating the number of musical sound generation channels to be allocated only to a specific tone, and setting all the numbers of musical sound generation channels allocated to other tones to zero. An electronic musical instrument according to claim 1 or 2 of the registered claims.
