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 model ID of the exclusive messages used
by this instrument is 00 65H.

The amount of data 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. 105).
*
For the address, size, and checksum, refer to “Examples of system exclusive messages
and calculating the checksum” (p. 107).

Regarding the checksum, please refer to page 107.

For the address, size, and checksum, refer to “Examples of System Exclusive Messages
and Calculating the Checksum” (p. 107).
*
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 40 ms of
time interval between them.
*
Regarding the checksum, please refer to page 107.
2. Transmitted Data
*
Messages that affect the system or the entire organ part are transmitted on the channel
specified by CONTROL MIDI CH. (p. 77).
*
Messages related to individual Organ parts are transmitted on the channels specified by
UPPER/LOWER/PEDAL ORGAN MIDI CH. (p. 77).
*
Messages related to the Orchestral Tones part are transmitted on the channel specified
by ORCHESTRAL TONES MIDI CH (p. 77).
