● 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 00H 00H 21H.
❍ 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. 7).
* Regarding the checksum, please refer to p. 20.
* Not received when the Receive Exclusive parameter (SYSTEM Common MIDI) is OFF.

* The amount of data that can be transmitted at one time depends on the type of data, and
data will be transmitted from the specified starting address and size. Refer to the address
and size given in "Parameter Address Map" (p. 7).
* Data larger than 256 bytes will be divided into packets of 256 bytes or less, and each
packet will be sent at an interval of about 20 ms.
* Regarding the checksum, please refer to p. 20.
* Not received when the Receive Exclusive parameter (SYSTEM Common MIDI) is OFF.
