摘要

Tone color data are stored in a tone generatorstorage region of a RAM. The tone generator datastorage region is searched upon occurrence ofperformance information indicative of a change of tonecolor, to determine whether tone color data selected bythe change of tone color are stored in the tonegenerator data storage region, and musical tonegeneration is controlled such that when a result ofthe searching indicates that the tone color dataselected by the change of tone color are stored in thetone generator data storage region, a musical tone isgenerated based on the tone color data, and, when thetone color data selected by the change of tone colorare not stored in the tone generator data storageregion, the tone color data are read out from a storagemedium storing the selected tone color data, andtransferred to and stored in the tone generator datastorage region, while generating a musical tone basedon other tone color data similar to the selected tonecolor data.
