Abstract:
1. A performance system comprising a plurality of playing terminals and a controller capable of communicating with each other, wherein said performance terminal is comprised of: a performance operation device adapted to generate performance data according to operations of a performer; a tone generator adapted to generate a tone based on the performance data; and a control device adapted to transmit performance data generated by said performance operation device to said controller, execute a communication process for inputting performance data received from said controller to said tone generator, and execute a mode switching process for switching between a local-on mode in which said performance operation device inputs the generated performance data to said tone generator to generate a tone and a local-off mode in which said performance operation device does not input the generated performance data to said tone generator, said controller is comprised of: a storage device adapted to store musical piece data consisting of a plurality of performance parts and including a plurality of performance data strings for each of the performance parts; and an automatic performance control device adapted to determine a tempo and/or a beat timing of automatic performance based on performance data received from each of said playing terminals, read out a performance data string for each of the performance parts from the musical piece data, assigning the read-out performance data string for each of the performance parts to each of the performance terminals, and transmit the assigned performance data string to each of said playing terminals individually, and wherein said automatic performance control device of said controller is adapted to transmit a local-off instruction message to all said playing terminals upon commencement of automatic performance according to the musical piece data, and said control device of said playing terminal is adapted to switch the mode to a local-off mode upon receiving the local-off instruction message from said controller.
