Claims

[Claims for Utility Model Registration] (1) Performance input means that can operate multiple operators at the same time, and operator data corresponding to the operation of the operators of this performance input means that can be transmitted to one of a plurality of sounding channels. In the sound generation channel assignment device for an electronic musical instrument, the sound source means is capable of simultaneously producing a plurality of musical tones by assigning them to the sound generation channels of the electronic musical instrument; When the number of operators operated by the input means exceeds the number of sound generation channels in the sound source means, the operator data corresponding to the two or more operated operators is transferred to at least one of the sound generation channels. A sound channel assignment device for an electronic musical instrument, comprising: an assigning means for cyclically and alternately assigning to two sound channels. (2) The allocation means assigns operator data corresponding to a plurality of operators from the operator corresponding to the first operation to the operator operated after the number of sounding channels by a value exceeding the number of sounding channels. Sound generation channel assignment for an electronic musical instrument according to claim 1, characterized in that the sound generation channels are cyclically and alternately assigned to at least one of the sound generation channels, and the operator data corresponding to other operations are assigned to the remaining sound generation channels. Device. (3) The sounding channels to which the control data is alternately allocated in a circular manner by the allocation means are as follows:
2. The sound generation channel allocation device for an electronic musical instrument according to claim 1, wherein the sound channel is the sound channel to which the operator data corresponding to the operator operated first is assigned. (4) A sound channel for an electronic musical instrument having a sound source means capable of allocating input pitch data to one of a plurality of sound channels and creating musical sound data based on the assigned pitch data. The allocation device allocates the input pitch data to an empty sound generation channel among the sound generation channels, and also controls the number of pitch data input at the same time.
and allocation means for circulating and alternately allocating two or more of the input pitch data to at least one of the sounding channels when the number of sounding channels in the sound source means is exceeded. A sound channel assignment device for an electronic musical instrument, characterized in that: (5) The allocation means assigns the plurality of pitch data, from the pitch data corresponding to the first input to the pitch data input later by the value exceeding the number of sound generation channels, to the sound generation channels. 5. The sound generation channel assignment device for an electronic musical instrument according to claim 4, wherein the pitch data is cyclically and alternately assigned to at least one of the sound generation channels, and the other pitch data is assigned to the remaining sound generation channels. (6) The electronic device according to claim 4, wherein the sounding channel to which the pitch data is alternately assigned in a circular manner by the assigning means is the sounding channel to which pitch data inputted first is assigned. Instrument sound channel assignment device.
