PURPOSE: To simplify the operation of the operators for changing musical tone control functions and to greatly improve operability by providing the processor with a second changeover means for changing over the musical tone control function corresponding to the operators operated by a second operation form according to the operation by the second operation form of the operators and changing over the musical tone control function corresponding to the operators exclusive of the operator operated by the second operation form to the second control form. CONSTITUTION: When any among the tone switches of an operator group 20 is turned on twice within the prescribed time interval, a CPU 10 judges these operations as double clicks and turns on only the tone corresponding to the double clicked tone switch and turns off all the other tones. The set state of the on/off of the tones is thereafter returned to the state before the double clicks of the previous time when the same tone switch as the double clocked tone switch is again double clicked. |
