Claims

[Claims for Utility Model Registration] (1) A keyboard having a plurality of keys, and pitches corresponding to the keys assigned to each of musical sound generation channels whose maximum number of simultaneous sounds is smaller than the number of keys on this keyboard. An electronic musical instrument comprising a musical tone generating means for generating a musical tone, and a channel assigning means for assigning a newly pressed key to one of the musical tone generating channels, wherein one of the musical tone generating channels is generating a musical tone. If the total number of musical sound generation channels that should generate musical tones exceeds the maximum number of simultaneous sound generation channels due to a new pressing of the key in the state, the newly pressed key As the musical sound generation channel to which is to be assigned, among the musical sound generation channels of the currently sounding pitch,
An electronic musical instrument, characterized in that an electronic musical instrument is provided with an allocation control means for controlling the channel allocation means to allocate a musical sound generation channel other than the musical sound generation channel generating a musical tone of a predetermined pitch. (2) The assignment control means selects a predetermined number of tones of a predetermined pitch from among the tones of the currently sounding pitch as the tones to which the newly pressed key is to be assigned. Claim 1 of the Utility Model Registration Claim, characterized in that the channel allocation means is controlled so as to allocate a musical sound generation channel other than the musical sound generation channels generating musical tones arranged in the order of pitches. electronic musical instruments. (3) The allocation control means controls the channel allocation means by rearranging key press information or key release information regarding the key corresponding to the musical tone currently being sounded in a predetermined order. An electronic musical instrument according to claim 1 or 2 of the invention registration claim. (4) Claims 1, 2, or 3 of the utility model registration claim, characterized in that the allocation control means controls the channel allocation means by detecting the end of the envelope of musical tones. An electronic musical instrument as described in any of the above.
