Abstract
A performance system capable of improving operability of switching local-on/off of performance terminals. T performance system comprises a performance terminal and a controller capable of communicating with each other. The performance terminal is comprised of a performance operation device, a tone generator, and a control device adapted to transmit performance data generated by the performance operation device to the controller, execute a communication process for inputting performance data received from the controller to the tone generator, and execute a mode switching process for switching between a local-on mode in which the performance operation device inputs the generated performance data to the tone generator to generate a tone and a local-off mode in which the performance operation device does not input the generated performance data to the tone generator. The controller is comprised of a storage device adapted to store musical piece data consisting of a plurality of performance data strings, 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 the performance terminal, read out a performance data string from the musical piece data, and transmit the read-out performance data to the performance terminal. The automatic performance control device is adapted to transmit a local-off instruction message to the performance terminal upon commencement of automatic performance according to the musical piece data, and the control device is adapted to switch the mode to a local-off mode upon receiving the local-off instruction message from the controller.
