Network system of musical equipments with message error check and remote status check

摘要

A musical network system has a plurality of musical equipments interconnected to each other through a communication network which circulates a control message for producing a musical sound. One musical equipment has a transmitter for transmitting a control message to the communication network. Another musical equipment has a receiver for receiving the control message from the communication network. An internal tone generator operates according to the received control message for producing a musical sound. A detector detects whether the received control message is a right one which may not disturb operation of the generator means or a wrong one which may disturb operation of the generator means. A transmitter returns an error message to the one musical equipment through the communication network when the detector detects that the received control message is the wrong one. Further, a receiver of the one musical equipment receives from the communication network status information which is returned by another musical equipment, and checks the returned status information to detect if mis-operation has occurred in another musical equipment for initiating recovery of the mis-operation.
