PROBLEM TO BE SOLVED: To improve the operability when editing tone colors and reduce the number of operating keys by effectively using them, by changing all the plural tone colors composing the tone color in batch when tone color parameters are changed by an editing means. SOLUTION: It is judged whether it is a part mode or a tone mode. In the case of a part mode, when currently selected performance parts are patch parts P1-P7, the tone color parameters of all tones of the selected patch parts are changed in batch according to the operation contents of the operating keys 12-15 for changing selected tone colors. Thus, when one of the patch parts P1-P7 is selected in the part mode, the tone color edition of the selected patch parts is performed on all the four tones T1-T4 composing the patch parts in batch according to the operation contents of the operating keys 12-15 for changing the tone color parameters, and the operability is improved. |
