Abstract
A performance information transmission system includes a performance information transmitter device and a performance information receiver device which are capable of correcting transmission errors in event information transmitted from the performance information transmitter device to the performance information receiver through a wire or radio communication. This correction does not require another transmission passes, cause a delay of the generation of the musical tone, or cause difficulties in restoring the burst error. The performance information transmitter device is equipped with state information generating device which generates state information for indicating the control state of a musical tone of a predetermined musical tone after a change has occurred in the event information. A transmit device transmits sequentially the event information and the state information generated by the state information generating device. Further, the performance information receiver device is equipped with a receiver for receiving sequentially an event information which causes a change in a predetermined musical tone and the state information indicating the control state of a musical tone of the predetermined musical tone. An event information correction device corrects the transmission error of the event information received by the receiver based on the state information received in the same manner.
