Abstract
An electronic musical instrument according to the present invention has oscillators for generating a tone waveform; a modulator for modulating a musical tone; a modulation controller for determining a degree of modulation to be performed by the modulator; and a central control unit for controlling the oscillators, the modulator and the modulation controller. A memory stores a current control value of the modulation controller, and an input/output device reads a control value stored in the memory, by the central controller, and/or writes a control value stored in the memory into the central controller to ensure the control of the degree of modulation and the alteration of frequency bands.
