PURPOSE:To eliminate the need for an input part and to facilitate the fine adjustment of the draw bar by using a sound volume operating foot pedal as a data input part for draw bars. CONSTITUTION:When a changeover switch 31 for instructing draw-bar control is placed in a state wherein draw-bar data can be inputted, a detection part 33 detects the input state and the sound volume operating foot (EXP) pedal serves as the draw-bar data input part; and its data are stored in a storage part 35, a control part 36 controls a sound source part 37, and data on a sound outputted by the sound source part 37 are reproduced by a reproduction part 38 to generate its sound. An input part need not be provided newly and draw-bar data on a continuation quantity can be inputted to plural feet at the same time. Both hands are free at the time of the input, so the sound can be confirmed. |
