BnH 64H llH
n = MIDI channel number: 0H - FH (ch.1 - 16)

<<< RPN >>>
Control Changes include RPN (Registered Parameter Numbers), which are
extended.
When using RPNs, rst 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 Data entry
MSB, LSB MSB, LSB Notes
00H, 00H mmH, llH Pitch Bend Sensitivity
mm: 00H - 18H (0 - 24 semitones)
ll: ignored (processed as 00H)
Up to 2 octave can be specied in semitone steps.
*
The Part Pitch Bend Range parameter (PROG:PITCH)
will change.
00H, 01H mmH, llH Channel Fine Tuning
mm, ll: 20 00H - 40 00H - 60 00H
(-4096 x 100 / 8192 - 0 - +4096 x 100 / 8192 cent)
*
The Part Fine Tune parameter (PROG:PITCH) will
change.
00H, 02H mmH, llH Channel Coarse Tuning
mm: 10H - 40H - 70H (-48 - 0 - +48 semitones)
ll: ignored (processed as 00H)
*
The Part Coarse Tune parameter (PROG:PITCH) will
change.
7FH, 7FH ---, --- RPN null
RPN and NRPN will be set as “unspecied.” Once
this setting has been made, subsequent
Parameter values that were previously set will not
change.
mm, ll: ignored

Program Change
Status 2nd byte
CnH ppH
n = MIDI channel number: 0H - FH (ch.1 - 16)
pp = Program number: 00H - 7FH (prog.1 - prog.128)
*
Not received when the Receive Program Change parameter (SysEx) is
OFF.

Channel Pressure
Status 2nd byte
DnH vvH
n = MIDI channel number: 0H - FH (ch.1 - 16)
vv = Channel Pressure: 00H - 7FH (0 - 127)

Pitch Bend Change
Status 2nd byte 3rd byte
EnH llH mmH
n = MIDI channel number: 0H - FH (ch.1 - 16)
mm, ll = Pitch Bend value: 00 00H - 40 00H - 7F 7FH (-8192

All Sounds O (Controller number 120)
Status 2nd byte 3rd byte
BnH 78H 00H
n = MIDI channel number: 0H - FH (ch.1 - 16)
*
When this message is received, all notes currently sounding on the
corresponding channel will be turned o.

Reset All Controllers (Controller
number 121)
Status 2nd byte 3rd byte
BnH 79H 00H
n = MIDI channel number: 0H - FH (ch.1 - 16)
*
When this message is received, the following controllers will be
set to their reset values.
Controller Reset value
Pitch Bend Change +/-0 (center)
Channel Pressure 0 (o)
Modulation 0 (o)
Expression 127 (max)
However the controller will be at minimum.
Hold 1 0 (o)
RPN unset; previously set data will not change
NRPN unset; previously set data will not change

Status 2nd byte 3rd byte
BnH 7BH 00H
n = MIDI channel number: 0H - FH (ch.1 - 16)
*
When All Notes O is received, all notes on the corresponding
channel will be turned o. However, if Hold 1 is ON, the sound will
be continued until these are turned o.
