PURPOSE:To facilitate operation by a hand and to perform various musical sound control corresponding to an operation mode. CONSTITUTION:When a turntable 28 is rotated in the clockwise direction A, a 1st slider 16 which is pressed by a 1st cam part 37 moves down and only a 1st fixed contact is made; when the turntable is rotated in the counterclockwise direction B, a 2nd slider 17 which is pressed by a 2nd cam pad 38 moves down and only a 2nd fixed contact is made. When the turntable 28 is pressed, the reverse surface of the turntable 28 presses both the 1st and 2nd sliders 16 and 17, which move down, so that the 1st and 2nd fixed contacts are both made. Therefore, the timbre of a generated musical sound is variously controlled by indicating the generation of a musical sound signal having different timbre corresponding to the making of only the 1st fixed contact, the making of only the 2nd contact, and the simultaneous making of the 1st and 2nd fixed contacts. |
