ABSTRACT:
An automatic performing system includes a performance information transmitting unit and a performance information receiving unit. Performance information is transmitted from the performance information transmitting unit to the performance information receiving unit. The transmitting unit waits for returned performance information from the receiving unit and compares the returned information with the transmitted information. If the returned information is determined to be unequal to the transmitted information, a retransmission command is transmitted to the receiving unit, thereby prohibiting the receiving unit from using incorrectly received performance information and ordering the receiving unit to wait for the next transmission from the transmitting unit. Thus, correctly received performance information is processed on a real time basis.
