Patent ID: 8389846

Claim:
An inner force sense controlling apparatus for giving rise to inner force sense to a player through manipulators of a musical instrument, comprising: a first load applier including a kinematical observer monitoring said manipulators and determining physical quantity expressing the movements of said manipulators, actuators respectively provided in association with said manipulators and responsive to driving signals representative of the amount of load to be applied directly to said associated manipulators so as give rise to a part of said inner force sense in said player, a data holder storing relations between said physical quantity and the amount of said load to be applied to said manipulators, and a controller having a selector connected to said kinematical observer and said data holder so as to specify the amount of said load to be applied on the basis of said physical quantity and a driver connected to said selector and said actuators so as to adjust said driving signals to values of magnitude corresponding to said load; and a second load applier connected to said manipulators, and having a mechanical load applier applying load directly to said manipulators in parallel to said actuators so as to give rise to another part of said inner force sense in said player and a mechanism for making said mechanical load applier stand idle in deactivate state.
