1DH rrH mmH Reverb send level of drum instrument
absolute change on specified drum instrument
rr: key number of drum instrument
mm: 00H - 7FH (zero - maximum)
1EH rrH mmH Chorus send level of drum instrument
absolute change on specified drum instrument
rr: key number of drum instrument
mm: 00H - 7FH (zero - maximum)
* Data entry LSB is ignored.
* The relative change means that the parameter value (e.g. -50 - 0 - +50)
will be added to the preset value.
* The absolute change means that the parameter value will be replaced by
the received value.
(16) RPN MSB/LSB (Controller number 100, 101)
✩
Status Second Third
BnH 65H mmH
BnH 64H llH
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
mm=MSB of the RPN
ll=MSB of the RPN
* Ignored when “Rx.RPN = OFF.”
* The values set by an RPN won’t be reset by receiving new Program
Change messages or Reset All Controllers.
**RPN**
An RPN (Registered Parameter Number) is an expanded control change
message.
Each function of an RPN is described by the MIDI Standard.
To use an RPN, set the RPN number (MSB/LSB) before sending data.
Then send data by Data entry message (Controller number 6/38).
It is then recommended to send RPN null (RPN number = 7FH/7FH) to pre-
vent the data from being unexpectedly change.
SCB-55 recognizes the following RPN functions.
RPN Data entry
MSB LSB MSB LSB Description
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
00H 00H mmH ––– Pitch bend sensitivity
mm: 00H - 18H (0 - 24 semitone)
Default value = 02H (two semitones)
ll: ignored (value=00H)
(Up to 2 octaves)
00H 01H mmH llH Master fine tuning
mm,ll: 00 00H - 40 00H - 7F 7FH
(-8192 x 100/8192 - 0 - +8191 x 100/8192 cents)
00H 02H mmH ––– Master coarse tuning
mm: 28H - 40H - 58H (-24 - 0 - +24 semitones)
ll: ignored (value=00H)
7FH 7FH ––– ––– RPN null
Return to disable condition.
The parameter already set retains its value.
mm, ll: ignored
<5> PROGRAM CHANGE
✩
Status Second
CnH ppH
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
pp=Program number : 00H - 7FH (prog.1 - prog.128)
* Current active voices are not affected when receiving Program Change mes-
sages. New sounds will be played after receiving Program Change messages.
* Ignored when “Rx.PROGRAM CHANGE = OFF.”
* In the drum part, Program change messages are ignored when the Bank is set
at 129 - 16384 (i.e. the value of the control change number 0 is not 00H).
<6> CHANNEL PRESSURE
✩
Status Second
DnH vvH
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
vv=Value : 00H - 7FH (0 - 127)
* Effect to the parameter set on System Exclusive Messages. The default set-
ting has no effect.
* Ignored when “Rx.CH PRESSURE (CAf) = OFF.”
<7> PITCH BEND CHANGE
✩
Status Second Third
EnH llH mmH
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
mm,ll=Value : 00 00H - 40 00H - 7F 7FH (-8192 - 0 - +8191)
* Effect to the parameter set on System Exclusive Messages. The default set-
ting is pitch bend.
* Ignored when “Rx.PITCH BEND = OFF”
[Channel Mode Messages]
<1> ALL SOUNDS OFF (Controller number 120)
Status Second Third
BnH 78H 00H
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
* When “All sounds off” is received, all sounds on a specified channel turn
off immediately. However, the state of channel messages does not
change. You must not use “All sounds off” message for “Note off.”
<2> RESET ALL CONTROLLERS
(Controller number 121) ✩
Status Second Third
BnH 79H 00H
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
* When “Reset all controllers” is received, the controller value of a specified
channel returns to the default values as follows.
Controller Default Value
Pitch bend change 0 (Center)
Polyphonic key pressure 0 (off)
Channel pressure 0 (off)
Modulation 0 (off)
Expression 127 (maximum)
Hold1 0 (off)
Portamento 0 (off)
Sostenuto 0 (off)
Soft 0 (off)
RPN disabled.
The parameter already set retains its old value.
NRPN disabled.
The parameter already set retains its old value.
<3> ALL NOTES OFF (Controller number 123)
✩
Status Second Third
BnH 7BH 00H
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
* When “All notes off” is received, all notes are turned off in the specified
channel. However, sound continues while Hold1 or Sostenuto is on.
<4> OMNI OFF (Controller number 124)
Status Second Third
BnH 7CH 00H
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
* OMNI OFF is only recognized as “All notes off”; the Mode doesn’t change.
<5> OMNI ON (Controller number 125)
Status Second Third
BnH 7DH 00H
n=MIDI channel number : 0H - FH (ch.1 - ch.16)
* OMNI ON is only recognized as “All notes off”; the Mode doesn’t change
(OMNI OFF remains).
