PROBLEM TO BE SOLVED: To enables a singer to regulate various kinds of parameters, such as sound volume adjustment, interval regulation, play release, even without using the hands while singing. SOLUTION: This input device is provided with switches which are members, such as pressure sensors, to detect the stepping pressures respectively corresponding to various kinds of the parameters, such as sound volume adjustment, interval regulation and play release, to a KARAOKE sing-along machine 3 at plural points on a sheet of a stepping pad 1. When the respective switch parts detect the stepped pressure by of the singer by stepping of the arbitrary switch parts with the feet of the singer, the switch parts input the regulation instruction information relating to the parameter kinds corresponding to the members of the respective detection points to the KARAOKE sing-along machine 3. |
