in pitch with the Control Number 6 (Data Entry MSB) and
Control Number 38 (Data Entry LSB) settings. There is no
change in pitch when Data Entry MSB is set to "64" and Data
Entry LSB to "0." The pitch is raised as the respective values
increase, and lowered as the respective values decrease.
Specifying the Range of Pitch Bend (p. 284)
• BendRng: Controller number 100 (value is 0), Controller
number 101 (value is 0), Controller number 6 (value is 0–
12)
<Procedure>
Enable the external MIDI device to send a Control Change
message.
For example, if you want to change the volume level, set the
external MIDI device to send Control Number 7 (Volume
message). In this case, the MIDI channel is matched to the
MIDI channel of the Part the volume of which you want to
change.
For information on how to make the settings, refer to the
owner's manual for your external MIDI device.
Operate the external MIDI device (adjust the controls, play
back using the sequencer, etc.) to send the settings.
Not only is the actual sound played changed, but the values
appearing in the display are changed as well.

What is RPN?
"RPN" (Registered Parameter Number) is an extension
message prepared by Control Change message. Use RPN
when using an external MIDI device to change the XV-
5080's Pitch or Pitch Bend range settings. An RPN has an
superior part (RPN MSB) and a subordinate part (RPN
LSB). The RPN MSB (Control Number 101) informs the
XV-5080 that a setting using RPN is to follow, and the
RPN LSB (Control Number 100) value tells the which
parameter is to be set. Lastly, the Data Entry (Control
Change 6) value sets the degree of change.
Once the XV-5080 has been received an RPN parameter,
all further Data Entry messages on that MIDI channel are
considered to apply to that 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.
For example, to raise the pitch of a certain Part by one
half-step (semitone) send the following Control Change
message from the external MIDI device.
• Controller number 100: value "2"
• Controller number 101: value "0"
• Controller number 6: value "65"
• Controller number 100: value "127" <- RPN null
• Controller number 101: value "127" <- RPN null
For more detailed information about RPN, please refer to
the "MIDI Implementation" (p. 282).
