ABSTRACT:
A computer portion70determines main reaction force RF0by use of a main reaction force table storing main reaction forces which vary according to the velocity and the depth of a depression of the key11. The computer portion70determines first ancillary reaction force RF1by use of a first ancillary reaction force table storing first ancillary reaction forces which vary according to the amount of depression of a lever32of a pedal apparatus30. The computer portion70adds the first ancillary reaction force RF1to the main reaction force RF0to obtain a composite reaction force to control a solenoid21on the basis of the composite reaction force so that a reaction force which is to be exerted on the key11will be the composite reaction force.
