<P>PROBLEM TO BE SOLVED: To provide technique which can transmit and receive performance data by wireless communication with low delay and in a stable manner. <P>SOLUTION: A performance data transmitter 2 wirelessly transmits MIDI data output from a MIDI apparatus 1 to a performance data receiver 3 by units of MIDI event. On receiving event data from the performance data transmitter 2, the performance data receiver 3 transmits response data as a response to the received event data. Every time transmitting one piece of event data, the performance data transmitter 2 waits to receive response data for a predetermined waiting time, and transmits the next event data when response data is received within the waiting time, on the other hand, when response data is not received within the waiting time, re-transmits the event data transmitted just before. <P>COPYRIGHT: (C)2013,JPO&INPIT |
