ABSTRACT:
A tone color of a tone to be generated is selected by a tone color selection switch and various parameters for realizing the selected tone color are generated. There are provided a first operator for designating a fine adjustment in a predetermined direction (e.g., increasing direction) with respect to a predetermined tone color determining element and a second operator for designating a fine adjustment in a direction opposite to the direction (e.g., decreasing direction) with respect to the predetermined tone color determining element. Operation data concerning the predetermined tone color determining element is formed in accordance with operations of the first and second operators. A parameter associated with the predetermined tone color determining element among the parameters for realizing the selected tone color is changed in accordance with this operation data. A tone signal generation circuit generates, in response to given tone pitch information and the tone color parameter, a tone signal corresponding to this tone pitch information with a tone color established by the tone color parameter. Therefore, fine adjustment of the tone color is achieved by merely operating one of the first and second operators corresponding to a desired direction of fine adjustment.
