An RJC message will be triggered when : • a WSD or RQD message has specified an illegal data address or size. ■ the device is not ready for communication. • an illegal number of addresses or data has been detected. • data transfer has been terminated by an operator. • a communications error has occurred. An ERR message may be sent out by a device on either side of the interface. Communication must be terminated immediately when either side triggers an ERR message. • Error occurs while device (A) is receiving data from device (B). 1) Data Transfer from device (A) u> device (B).

If the unit falls to receive a message 300 milliseconds after the previous one. it judges there is a problem somewhere in Ihe MIDI patch, doing the maximum expression contra!
