Performance apparatus and tone generation method therefor
First Claim
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.

Abstract
A Plurality of key switches for tone-generating are arranged two-dimensionally. Mode setting section sets a tone adjusting mode in which the key switches are caused to function as tone-adjusting operators. In the tone adjusting mode, adjustment of a predetermined tone factor (e.g., tone pitch, tone length, tone volume or tone color) is permitted in response to operation of the key switch. For example, once a user moves a finger to change a Y-coordinate position of the key switch in the tone adjusting mode, an amount of the movement, i.e. a difference between Y-coordinates of two or more successively-operated key switches, is detected, and the thus-detected movement amount is set as a value for adjusting a tone volume or the like. All of light-emitting elements located at Y-coordinate positions of the key switches may be illuminated in a line, to allow the user to visually confirm the adjustment and operation.

11. 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.

12. 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. - View Dependent Claims (13, 14, 15, 16)
