Performance apparatus and tone generation method using the performance apparatus
First Claim
1. A performance apparatus comprising:
- a plurality of key switches arranged in a plurality of key switch rows;
a plurality of light emitting elements provided in corresponding relation to the key switches;
a detection section that detects an operated key switch for each of the key switch rows;
a light emission control section that sequentially illuminates the light emitting elements, on the basis of detection by said detection section, in such a manner that an illuminated position reciprocates between the operated key switch and the key switch located at a first predetermined position in the same key switch row of the operated key switch; and
a tone generation section that generates at least one of tones allocated to the key switch row when the key switch located at a second predetermined position in the same key switch row of the operated key switch is illuminated.

Abstract
Key switches are arranged to form plural rows, and light emitting elements are provided in corresponding relation to the key switches. For each of the rows, any operated key switch is detected, and, on the basis of such detection, the light emitting elements are sequentially illuminated so that an illuminated position reciprocates between the operated key switch and the key switch located at a predetermined position of the row the operated key switch belongs to. In synchronism with illumination of the key switch located at a predetermined position of the row, at least one of tones allocated to the row is generated. When duration of operation of the operated key switch is greater than a predetermined time, the light emitting elements located in a predetermined range may be illuminated in accordance with a predetermined pattern, and an effect may be imparted to a tone corresponding to the operated key switch.
