<P>PROBLEM TO BE SOLVED: To notify a user of the tempo through a pedal by tactile sense. <P>SOLUTION: A setting operation part 17 receives setting or the like of music selection, tempo, rhythm, and modes. In the modes (first to third modes) for sensing the tempo, when a TCL value indicates beat timing, the tempo sensing device calculates a moving amount x of a plunger 35 from a detection signal of a position sensor 42, determines the duty ratio corresponding to designated reaction force strength indication value F1 and the moving amount x by referring to a duty ratio map 21, and outputs a drive signal to a solenoid body 30 by generating the drive signal of the duty ratio. <P>COPYRIGHT: (C)2009,JPO&INPIT |
