Resumen del manual
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! (Genera! purpose controller I), ami cancelling mute control (General purpose controller 5), and stopping 300 milliseconds - interval monitoring of the incomming signal ■ Control Change General Purpose Controller 1 3.EXCLUSIVE COMMUNICATION Status BnH &£SQä юн Third vvH Model - ID sp in the exclusive message : 26H Device - ID if : Basic channel A less 1 ■ One - Way Communication n » MIDI channel number : OH - FH (1 - 16) Request data 1 RQ1 (11H) vv = Expression : ООН - 7FH (0 - 127) When RQ1 received contains a start address listed in Parameter Base Address and the When w is 7FH (127), it is ihe Master Volume value. size is the same, GS-6 sends the corresponding data using Data Set (DTI).
