MIDI Implementation

●Data Transmission

This instrument can use exclusive messages to exchange many varieties of internal settings with other devices.

The model ID of the exclusive messages used by this instrument is 6AH.

❍Data Request 1 RQ1

This message requests the other device to transmit data. The address and size indicate the type and amount of data that is requested.

When a Data Request message is received, if the device is in a state in which it is able to transmit data, and if the address and size are appropriate, the requested data is transmitted as a Data Set 1 (DT1) message. If the conditions are not met, nothing is transmitted.

*The amount of data that is transmitted at one time is fixed for the type of data, and only data of the fixed starting address and size will be transmitted. Refer to the address and size given in “Parameter Address Map” (p. 74).

*Data whose size is greater than 128 bytes should be divided into packets of 128 bytes or less and transmitted. Successive “Data Set 1” messages should have at least 20 ms of time interval between them.

*For the checksum, refer to (p. 86).

*This message is not received in GM mode.

This device is able to receive GS Exclusive messages only for Scale Tune settings.
