Performance apparatus and tone generation method therefor

A performance apparatus comprising:

• a plurality of key switches arranged two-dimensionally;
• 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 a key switch actuated 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 the tone to be generated by said tone generation section;
• a tone adjustment section that adjusts, while the tone adjusting mode is actuated, a predetermined tone factor of the tone with at least one of the key switches;
• 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 with the at least one key switch,
• wherein said tone adjustment section adjusts the predetermined tone factor in accordance with an X- or Y-coordinate position of one of the key switches for adjusting the predetermined tone factor, or in accordance with a difference between X- or Y-coordinate positions of at least two of the key switches for adjusting the predetermined tone factor, and
• wherein said light emission control illuminates in a line all of the light-emitting elements located at the X- or Y-coordinate position of each of the key switches actuated for adjusting the predetermined tone factor.

A method of generating a tone with a performance apparatus including a plurality of key switches arranged two-dimensionally, each key switch being assigned a tone pitch, a memory storing tone data corresponding to the plurality of key switches, and a light-emitting element associated with each of said plurality of key switches, the method comprising:

• a tone generation step of, on the basis of the tone data stored in the memory, generating a tone corresponding to any key switch actuated among the plurality of key switches;
• a step of actuating 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 step;
• a tone adjustment step of adjusting 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 control step of controlling 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.

A computer-readable medium storing a computer program for controlling a performance apparatus including a plurality of key switches arranged two-dimensionally, each key switch being assigned a tone pitch, a memory storing tone data corresponding to the plurality of key switches, and a light-emitting element associated with each of said plurality of key switches the computer program containing:

• a tone generation instruction for, on the basis of the tone data stored in the memory, generating a tone corresponding to any key switch actuated among the plurality of key switches;
• a setting instruction for actuating 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 instruction;
• a tone adjustment instruction for adjusting 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;
• and
• a control instruction for controlling 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.
