Abstract
Tone color data are stored in a tone generator storage region of a RAM. The tone generator data storage region is searched upon occurrence of performance information indicative of a change of tone color, to determine whether tone color data selected by the change of tone color are stored in the tone generator data storage region, and musical tone generation is controlled such that when a result of the searching indicates that the tone color data selected by the change of tone color are stored in the tone generator data storage region, a musical tone is generated based on the tone color data, and, when the tone color data selected by the change of tone color are not stored in the tone generator data storage region, the tone color data are read out from a storage medium storing the selected tone color data, and transferred to and stored in the tone generator data storage region, while generating a musical tone based on other tone color data similar to the selected tone color data.
