Control Changes include RPN (Registered Parameter Numbers), which are
extended.
When using RPNs, first RPN (Controller numbers 100 and 101; they can be sent in
any order) should be sent in order to select the parameter, then Data Entry
(Controller numbers 6 and 38) should be sent to set the value. Once RPN messages
are received, Data Entry messages that is received at the same MIDI channel after
that are recognized as changing toward the value of the RPN messages. In order
not to make any mistakes, transmitting RPN Null is recommended after setting
parameters you need.
This device receives the following RPNs.
RPN
MSB, LSB
00H, 00H mmH, llH Pitch Bend Sensitivity
00H, 01H mmH, llH Channel Fine Tuning
00H, 02H mmH, llH Channel Coarse Tuning

Notes
mm: 00H - 18H (0 - 24 semitones)

Up to 2 octave can be specified in semitone
steps.

mm: 10H - 40H - 70H (-48 - 0 - +48 semitones)
ll: ignored (processed as 00H)
RPN and NRPN will be set as “unspecified.”
Once this setting has been made, subsequent
Data Entry messages will be ignored. (It is not
necessary to transmit Data Entry for RPN Null
settings.)
Parameter values that were previously set will
not change.

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 53H.
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. 6).
* For the checksum, refer to (p. 14).
* Not received when the Receive Exclusive (Rx Sys-Ex) parameter (SYSTEM
Common MIDI/USB) is OFF.
