ABSTRACT:
In order to accurately simulate the sounding system of the stringed instrument such as the violin and cello, an electronic musical instrument provides a performance unit such as a keyboard and a multi-channel sound source unit. As the sound source unit, there is provided a plurality of string sound generating circuits, each corresponding to each of plural strings provided in the stringed instrument, each of which forms a musical tone waveform signal having a different tone color. When performance information is created by operating the performance unit, one of the string sound generating circuits and its fingering position is selected on the basis of the preceding tone-generation assignment state, and then tone-generation corresponding to the created performance information is assigned to the selected circuit. Normally, plural musical tones can be sounded simultaneously in the stringed instrument. However, due to the restriction of the performance which must be inevitably occurred when playing the actual stringed instrument, there is established a restriction condition for the simultaneous tone-generation operation.
