1. A performance apparatus comprising:

  • a plurality of key switches arranged two-dimensionally, each key switch being assigned a tone pitch;

    a memory storing tone data corresponding to said plurality of key switches;

    a tone generation section that, on the basis of the tone data stored in said memory, generates a tone corresponding to any actuated key switch among said plurality of key switches;

    a mode setting section that actuates a tone adjusting mode for causing the key switches to function as tone-adjusting operators for each tone to be generated by said tone generation section; and

    a tone adjustment section that adjusts with at least one of the key switches, while the tone adjusting mode is actuated, a predetermined tone factor of each tone to be generated;

    a light-emitting element associated with each of said plurality of key switches; and

    a light emission control section that controls light emission of the light-emitting elements to illuminate in a line all of the light-emitting elements located at an X- or Y-coordinate position of any actuated key switch for adjusting the predetermined tone factor.
