Patent ID: 8008565

Claim:
A performance apparatus comprising: a plurality of key switches arranged in two dimensions along X- and Y-coordinate axes, an X-coordinate position of each of said key switches being associated with tone generation timing, while at a same time, a Y-coordinate position of each of said key switches is associated with a discrete tone pitch; a storage section that stores a music piece data set comprising tone generating data having data of tone pitches and tone generation timing associated with said key switches; a repeat-section setting section that, in a repeat-section setting mode, causes the plurality of key switches to function as setting operators and sets a repeat section of the music piece data set on the basis of the X-coordinate position of any operated one of said key switches, wherein when the repeat-setting section sets the repeat section, the repeat-setting section does not set a tone pitch based on the Y-coordinate position of the key switch operated to set the repeat section; a reproduction section that reproduces the music piece data set stored in said storage section, said reproduction section repetitively reproducing the tone generating data of the music piece data set included in the repeat section set by said repeat-section setting section; and a tone-pitch-range setting section that, in a tone-pitch-range setting mode, causes the plurality of key switches to function as setting operators and sets a reproducible tone pitch range on the basis of the Y-coordinate position of any operated one of said key switches, wherein said reproduction section reproduces, from among the tone generating data to be repetitively reproduced, only tone generating data having tone pitches within the reproducible tone pitch range set by said tone-pitch-range setting section and, consequently, does not reproduce at least part of the tone generating data because the part is outside of the reproducible tone pitch range set by said tone-pitch-range setting section.
