Control Changes include RPN (Registered Parameter Numbers), which are extended
parameters whose function is defined in the MIDI specification.
When using RPNs, first the RPN (Controller numbers 100 and 101; they can be sent in any
order) is transmitted to specify the parameter you wish to control. Then, Data Entry
messages (Controller numbers 6 and 38) are used to set the value of the specified parameter.
Once a RPN parameter has been specified, all further Data Entry messages on that channel
are considered to apply to that specified parameter. In order to prevent accidents, when the
desired setting has been made for the parameter, it is recommended that RPN be set to Null.
This device transmits the following RPNs.

MSB LSB Notes
00H 00H mmH - Pitch Bend Sensitivity
mm: 00H - 0CH (0 - 12 semitones)
ll: ignored (processed as 00H)
Up to 1 octave can be specified in semitone steps.
* The Bend Range Up/Down will also be
changed.
* Not received by the Rhythm Part (Part 10).

* In Patch mode, the Master Tune (SYSTEM)
will change.
* In Performance mode, the Fine Tune
(PERFORM) of each Part will change. When
received on the Control channel, the Master
Tune (SYSTEM) will change.
00H 02H mmH - Channel Coarse Tuning
mm: 10H - 40H - 70H (-48 - 0 - +48 semitones)

* Not received in Patch mode.
* In Performance mode, the Coarse Tune
(PERFORM/PART) of each Part will change.

■ System Exclusive Messages
There is a kind of the Universal Non-realtime messages and the Data Set (DT1) messages in
the System Exclusive messages transmitted by this device.

* The amount of data transmitted at one time is fixed for the type of data, and the data will
be transmitted with the fixed starting address and size. Refer to the address and size
given in “Parameter Address Map” (p. 74).
* Large amounts of data must be divided into packets of 128 bytes or less, and transmitted
at intervals of approximately 20 ms.
* For the checksum, refer to (p. 86).
