Keyboard musical instrument equipped with electromagnetic key touch generator for imparting piano key-touch to player

A keyboard musical instrument comprising:

• a plurality of keys turnable along trajectories between respective rest positions and respective end positions;
• a plurality of key sensors respectively monitoring said plurality of keys, and respectively producing key status signals each representative of current key status of associated one of said plurality of key sensors;
• a plurality of first resilient members respectively associated with said plurality of keys so as to urge the associated keys toward said rest positions;
• a plurality of second resilient members respectively associated with said plurality of keys so as to urge the associated keys toward said end positions, a first resilient force of each of said plurality of second resilient members being balanced with a second resilient force of associated one of said plurality of first resilient members at the rest position of associated one of said plurality of keys;
• a plurality of key actuators generating forces exerted on said plurality of keys, respectively, so as to build up resistances to key motions from said rest positions toward said end positions;
• and
• a controller connected to said plurality of actuators, and responsive to said key status signals so as to change each resistance depending upon said current key status of associated one of said plurality of keys on the trajectory.
