Note on
Status 2nd byte 3rd byte
9nH kkH vvH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
kk = note number: 00H-7FH (0-127)
vv = note on velocity: 01H-7FH (1-127)
* Note numbers outside the range of 18-113 are transposed to the nearest octave within
this range.
* Transpose function does not affect the recognized note numbers.
●
Control Change
* The value specified by a Control Change message will not be reset even by a Program
Change, etc.
❍
Data Entry (Controller number 6, 38)
Status 2nd byte 3rd byte
BnH 06H mmH
BnH 26H llH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm, ll = the value of the parameter specified by RPN
* Data entry messages are recognized only when received on the basic channel.
❍
Volume (Controller number 7)
Status 2nd byte 3rd byte
BnH 07H vvH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Volume: 00H-7FH (0-127), Initial Value = 7FH (127)

vv = Control value: 00H-7FH (0-127) 0-63 = OFF, 64-127 = ON
❍
RPN MSB/LSB (Controller number 100, 101)
Status 2nd byte 3rd byte
BnH 65H mmH
BnH 64H llH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm = upper byte of parameter number specified by RPN
ll = lower byte of parameter number specified by RPN
* The value specified by RPN will not be reset even by messages such as Program Change
or Reset All Controller.
* RPN messages are recognized only when received on the basic channel.
**RPN**
The RPN (Registered Parameter Number) messages are expanded control changes, and each
function of an RPN is described by the MIDI Standard.
To use these messages, you must first use RPN MSB and RPN LSB messages to specify the
parameter to be controlled, and then use Data Entry messages to specify the value of the
specified parameter. Once an RPN parameter has been specified, all Data Entry messages
received on that channel will modify the value of that parameter. To prevent accidents, it is
recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished
setting the value of the desired parameter.
On the C-280, RPN can be used to modify the following parameters.
RPN Data entry
MSB LSB MSB LSB Explanation
00H 01H mmH llH Master Fine Tuning
mm, ll: 00 00H - 40 00H - 7F 7FH (-100 - 0 - +99.99
cents), Initial Value = 40 00H (± 0 cent)
7FH 7FH --- --- RPN null
Set condition where RPN and NRPN are
unspecified. The data entry messages after set
RPN null will be ignored.
(No Data entry messages are required after RPN
null).
Settings already made will not change.

Program Change
Status 2nd byte
CnH ppH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
pp = Program number: 00H..37H (prog.1..prog.56)
Received program change message are assigned as follows.
prog. tone
1 Organ Manual
2 Ensemble Chime
3 Ensemble Celesta
4 Ensemble Choir
17 Ensemble Chime + Organ Manual
33 Ensemble Celesta + Organ Manual
49 Ensemble Choir + Organ Manual
* “+” indicatesadualtone.'
* Program numbers not in the above table are ignored.
* The switch to the requested Ensemble Tone is made when the first new Note On
message arrives after the Program Change has been received. Organ Tones are changed
immediately after reception of the Program Change.
* When the C-280 receives Program Change messages that include requests for Organ
Tones, the [Manual] button is selected.
* Organ Tones are set by mean of Program Changes, and System Exclusive messages that
indicate the status of Draw knobs.
For more information about the System Exclusive messages that indicate the status of
Draw knobs, refer to "3. Parameter Address Map."
