ABSTRACT:
An electronic musical instrument having a plurality of keys is provided with a depressed key detector which detects depressed keys and produces key identifying signals; a highest signal detector which detects a highest one among the key identifying signals having a highest priority in accordance with a predetermined order of priority; a musical tone producing unit responsive to the detected highest signal for producing a musical tone of a tone pitch corresponding to the highest signal; a reference memory device for storing the detected highest signal in accordance with a predetermined condition; and a controller for inhibiting the musical tone producing unit from producing the musical tone according to a relationship between the detected highest signal and an output of the reference memory device.
Thus the progression of simultaneous plural key depressions provides a melody performance including rests.
