Claims (1)

[Claims for Utility Model Registration] (1) A 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 the plurality of sound generation channels. In a sound generation channel assignment device for an electronic musical instrument having a sound source means capable of simultaneously producing a plurality of musical tones by assigning them to sound generation channels, the control data is assigned to a vacant sound generation channel among the sound generation channels;
When the number of operators being operated by the performance input means exceeds the number of sound generation channels in the sound source means, the operator corresponding to the last operation is moved forward by the value that exceeds the number of sound generation channels. The present invention is characterized by comprising an allocation means for circulating and alternately assigning the operator data corresponding to the plurality of operators up to the operator that has been assigned to at least one of the plurality of sounding channels. Sound channel assignment device for electronic musical instruments. (2) A claim characterized in that the sounding channel to which the manipulator data is cyclically and alternately allocated by the allocating means is the sounding channel to which the manipulator data operated in the highest number of simultaneous sound productions is allocated. 1. The sound channel allocation device for an electronic musical instrument according to item 1. (3) Sound generation channel assignment for an electronic musical instrument having a sound source means capable of allocating input pitch data to one of a plurality of sounding channels and creating musical tone data based on the assigned pitch data. In the device, when the input pitch data is assigned to a vacant one of the sound generation channels, and the number of pitch data input at the same time exceeds the number of sound generation channels in the sound source means,
These plural pitch data, from the pitch data corresponding to the last input to the pitch data input previously by the value exceeding the number of pronunciation channels, are transferred to at least one of the above pronunciation channels. 1. A sounding channel assignment device for an electronic musical instrument, characterized in that the sounding channel allocation device for an electronic musical instrument is characterized in that the pitch data is circulated and alternately assigned to the remaining sounding channels, and other pitch data is assigned to the remaining sounding channels. (4) The sounding channel to which the pitch data is allocated alternately in a circular manner by the allocating means is the sounding channel to which the pitch data is allocated in the order of the maximum number of simultaneous pronunciations. Sound channel assignment device for electronic musical instruments.
