A parameter setting device includes faders 15 a to 15 c to which a plurality of parameters are respectively allotted. The plural parameter values are respectively set in accordance with the operation positions of faders 15 a to 15 c. When scene selection switches 24 to 26 are operated, the plural parameter values are gradually changed in accordance with the lapse of time towards the final values represented by scene data. During this change of the parameter values, faders 15 a to 15 c are driven by a motor and move in correspondence with the parameter values. When invalidation switches 12 a to 12 c , 21 are operated during this movement of faders 15 a to 15 c, the movement of faders 15 a to 15 c is controlled to be stopped, and the parameter values are instantaneously changed to the final values according to the scene data. When scene selection switches 24 to 26 are operated after the operation of invalidation switches 12 a to 12 c , 21 , the movement of faders 15 a to 15 c is controlled to be prohibited, and the parameter values are instantaneously changed to the final values according to the scene data. When release switches 13 a to 13 c , 22 are operated after these, faders 15 a to 15 c move to positions corresponding to the parameter values.
