Abstract:
1. An electronic supporting system for a human player who plays on a musical instrument equipped with at least one manipulator moved by said human player from a rest position to an end position through a track, comprising: an actuator provided for said at least one manipulator, and responsive to a driving signal for exerting an assisting force on said at least one manipulator, thereby making load for moving said at least one manipulator on said track sharable between said human player and said actuator; a sensor monitoring said at least one manipulator, and producing a detecting signal representative of an actual physical quantity expressing movements of said at least one manipulator on said track; and a controller connected to said sensor and said actuator, checking said actual physical quantity to see whether said at least one manipulator reaches a target position on said track for producing an answer, and varying a magnitude of said driving signal depending upon said answer for removing said assisting force from said at least one manipulator at said target position.
