Abstract
Two tone sources having different tone generation systems such as an FM tone source and a PCM tone source are provided. Tone signals are generated in the two tone sources in response to tone generation designation information such as keyboard performance information. One of the tone sources synthesizes a tone by employing a modulation operation such as FM or AM and, as a modulating signal supplied thereto, an output tone signal of the other tone source can be selectively used. A single complex tone color is constructed of plural element tone colors and which tone source should generate a partial tone signal corresponding to each element tone color can be designated individually with respect to each element tone color in response to element type information. With respect to a desired element tone color, editing of contents of its parameter information can be made as desired. In data editing, data of a desired complex tone color is transferred to an edit memory section and editing is applied to data stored therein. The number of tone signals to be generated simultaneously in response to common tone generation designation information can be set as desired and generated tone signals are added and synthesized to form a single tone signal. In this manner, a more complex and diversified tone can be formed as desired.
