PROBLEM TO BE SOLVED: To easily revise a control parameter even by a beginner regardless of the timing of performance by providing a pitch extraction means extracting a pitch of a voice inputted by a voice input means and a control parameter revision means revising a control parameter based on the pitch extracted by the pitch extraction means. SOLUTION: The output of the voice input means is supplied to the pitch extraction means. The pitch extraction means extracts the pitch of the inputted voice. The control parameter revision means revises various control parameters according, to the pitch extracted by the pitch extraction means. An electronic musical instrument controls a sound source based on the revised control parameter. Thus, the sound according to the control parameter is generated. In such a manner, by this control parameter revising device, since the control parameter is revised by the voice without using a hand or a foot, the control parameter is revised easily even while performing. |
