Performance apparatus and tone generation method

A method for generating a tone under control of a computer in a performance apparatus which includes:

• a plurality of key switches arranged in two dimensions along X- and Y-coordinate axes, an X-coordinate position of each of the key switches being associated with tone generation timing, while at a same time, a Y-coordinate position of each of the 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;
• and the computer, said method comprising:
• a repeat-section setting step of, in a repeat-section setting mode, causing the plurality of key switches to function as setting operators and setting a repeat section of the music piece data set on the basis of the X-coordinate position of any operated one of the key switches, wherein when the repeat-setting step sets the repeat section, the repeat-setting step does not set a tone pitch based on the Y-coordinate position of the key switch operated to set the repeat section;
• a reproduction step of reproducing the music piece data set stored in the storage section, said reproduction step repetitively reproducing the tone generating data of the music piece data set included in the repeat section set by said repeat-section setting step;
• and
• a tone-pitch-range setting step of, in a tone-pitch-range setting mode, causing the plurality of key switches to function as setting operators and setting a reproducible tone pitch range on the basis of the Y-coordinate position of any operated one of the key switches,
• wherein said reproduction step 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 step 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 step.

• a reproduction section that reproduces the music piece data set stored in said storage section, said reproduction section generating only the tone generating data, included in the music piece data set, 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.
