ABSTRACT:
When a switch for selecting tone control information has been operated once, presence of a first mode for selecting the tone control information is judged and when the switch has been continuously operated for predetermined plural times, presence of a second mode for adjusting contents of the tone control information is judged. When presence of the first mode has been judged, processing of the first mode for selecting the tone control information corresponding to the switch is executed. In this case, the switch functions as a switch for selecting desired tone control information in accordance with the proper purpose of the switch. When presence of the second mode has been judged, processing of the second mode for adjusting contents of the selected tone control information is executed. In this case, the switch functions as a switch for changing the mode from the first mode to the second mode. By differing the manner of operation in this manner, the same switch therefore can be provided with plural functions so that no particular mode selection switch is required.
