Abstract:
1. A reactive force control apparatus for a pedal of an electronic keyboard apparatus, comprising: a pedal supported for movement in response to at least one of depression and release operation performed thereon; a movement detection section that detects movement of the pedal; a drive section that produces a reactive force to be imparted to the pedal, based on an electric driving force thereof, in response to the at least one of depression and release operation of the pedal; a reference reactive force impartment table defining intensities of the reactive force corresponding to amounts of the at least one of depression and release operation of the pedal; a setting value input section operable to input a setting value for setting a reactive force responsive to the at least one of depression and release operation of the pedal; and a reactive force control section that controls the reactive force to be produced by said drive section, said reactive force control section changing content of the reference reactive force impartment table, on the basis of the setting value inputted via said setting value input section, to thereby create a changed reactive force impartment table, so that said reactive force control section controls the reactive force to be produced by said drive section by referring to the changed reactive force impartment table in accordance with a pedal movement detection signal outputted by said movement detection section.
