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 size of data that can be transmitted at one time is fixed for each type of data. and
data requests must be made with a fixed starting address and size. Refer to the address
and size given in "Parameter Address Map" (p. 190).
* For the checksum, refer to (p. 204).
* This message is not received if the Rx.Exc parameter (SYSTEM/MIDI/SYS-EXC MIDI) is
OFF.

* 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. 190).
* 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. 204).
