Abstract
A musical tone generator includes first and second tone generator units respectively having a plurality of musical tone generation channels, a designating device for designating tone colors of musical tones, and a CPU for enabling respective tone generation channels to be selectively assigned with different tone colors. The usage of the plural tone generator units is also controlled by discriminating whether or not the input performance data can be processed by the first tone generator unit. When the CPU determines that the input performance data can be processed by the first tone generator unit, it controls musical tone production in the first tone generator unit based on the performance data. When the CPU determines that the input performance data cannot be processed by the first tone generator unit, it controls musical tone production in the second tone generator unit based on the performance data.
