Patent ID: 7536257

Claim:
A performance apparatus comprising: an input device having a plurality of matrix switches arranged in a two-dimensional matrix pattern, each of the matrix switches being designatable as a coordinate in a two-dimensional area; a sounding data generating device that generates sounding data corresponding to designated coordinates in the two-dimensional area; a musical tone generation instructing device that instructs sounding of musical tones based on the sounding data generated by said sounding data generating device; and a moving coordinate generating device that sets a moving route based on the designation of at least two coordinates, and generates moving coordinates indicating corresponding present position coordinates on the set moving route among the coordinates in the two-dimensional area, wherein at least when the moving coordinates reach predetermined coordinates on the moving route, said sounding data generating device generates sounding data corresponding to the predetermined coordinates, and said musical tone generation instructing device instructs sounding of a musical tone based on the sounding data generated in association with the predetermined coordinates.
