PURPOSE:To make a touch feeling that a player has, constant irrespectively of the sound volume of an electronic sound source. CONSTITUTION:A thrust bar 44 which is fixed to a hammer relay 42 can be moved up and down by a stepping motor 149 and the microcomputer 187 of a sound source device 171 elevates the thrust bar 44 more and more as sound volume set with a sound volume switch 179 is smaller and smaller. Then, a string strike part 22 in a stationary state is pushed by a hammer rail 42 to come close to strings 100, and the touch feeling becomes light. When the sound volume is decreased, it normally seems that the touch feeling becomes heavy, but the touch feeling is varied corresponding to the manipulated variable of the sound volume switch 179, so the touch feeling that the player has, can be made constant irrespectively of the sound volume. |
