PURPOSE:To realize pitch and bend operation for an optional time through easy and natural operation by controlling a pitch corresponding to the depression position of a key. CONSTITUTION:When a keyboard 1 is depressed, its depression is detected by a key depression detecting circuit 3 and key code data corresponding to the depressed key is outputted to a CPU 4 through a bus. The CPU 4 reads the input key code data and controls a sound source circuit 9 corresponding to the read result to generate a musical sound corresponding to the depressed key. The musical sound outputted by the sound source circuit 9 is supplied to a sound system 10 and outputted. At this time, the pitch Pk of the output musical sound is stored in a ROM 6. The CPU 4 controls the pitch of the musical sound corresponding to the pitch Pk. A bent width setting switch among panel switches 7 is operated to vary the pitch and bend width. |
