Channel Mode Messages - Roland AT-90SL Manual

* Parameters marked "relative change" will change relative to the preset value.
* Parameters marked "absolute change" will be set to the absolute value of the parameter,
regardless of the preset value.
❍ RPN MSB/LSB (Controller number 100, 101)
Status 2nd bytes
BnH 65H
BnH 64H
n = MIDI channel number:
mm = upper byte of parameter number specified by RPN
ll = lower byte of parameter number specified by RPN
* Not received when Rx.RPN = OFF. (Initial value is ON)
* The value specified by RPN will not be reset even by messages such as Program Change
or Reset All Controller.
**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.Refer to Section 6. "Examples of actual MIDI
messages" <Example 4> (p. 17).
On the AT-90SL/80SL, RPN can be used to modify the following parameters.
RPN Data entry
MSB LSB MSB LSB Explanation
00H 00H mmH --- Pitch Bend Sensitivity [GM2] [GM1] [GS] [AT]
mm: 00H-18H (0-24 semitones), Initial Value = 02H (2
semitones)
ll: ignored (processed as 00h)
specify up to 2 octaves in semitone steps
00H 01H mmH llH Master Fine Tuning
mm, ll: 20 00H - 40 00H - 60 00H (-50 - 0 - +50 cents), Initial
Value = 40 00H (0 cent)
ll: ignored (processed as 00h)
Refer to 6. Supplementary material, "About tuning" (p. 18)
00H 02H mmH --- Master Coarse Tuning
mm: 10H - 40H - 70H (-48 - 0 - +48 semitones), Initial Value
= 40H (0 cent)
ll: ignored (processed as 00h)
00H 05H mmH llH Modulation Depth Range
mm, ll: 00 00H - 06 00H
(0 - 16384 * 600 / 16384 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.
mm, ll: ignored
● Program Change [GM2] [GM1] [GS]
Status 2nd bytes
CnH ppH
n = MIDI channel number:
pp = Program number:
* Not received when Rx.PROGRAM CHANGE = OFF [GS]. (Initial value is ON)
* After a Program Change message is received, the sound will change beginning with the
next Note-on. Voices already sounding when the Program Change message was
received will not be affected.
* When MIDI-IN Mode = Mode-2, it should be used System Exclusive messages to change
the voice of keyboard part (p. 12).
* Not Received in Keyboard Part.
● Channel Pressure [GM2] [GM1] [GS]
Status 2nd bytes
DnH vvH
n = MIDI channel number:
vv = Channel Pressure:

00H-7FH (prog.1-prog.128)

00H-7FH (0-127)
* Not received when Rx.CH PRESSURE (CAf) = OFF. [GS] (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial
settings there will be no effect [GS].
● Pitch Bend Change [GM2] [GM1] [GS] [AT]
Status 2nd byte
EnH llH
n = MIDI channel number:
mm, ll = Pitch Bend value:
* Not received when Rx.PITCH BEND = OFF [GS]. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial
settings the effect is Pitch Bend [GS].

■ Channel Mode Messages

● All Sounds Off (Controller number 120) [GM2] [GS] [AT]
Status 2nd byte
BnH 78H
n = MIDI channel number:
* When this message is received, all notes currently sounding on the corresponding
channel will be turned off.
● Reset All Controllers (Controller number 121)
[GM2] [GS]
Status 2nd byte 3rd byte
BnH 79H
n = MIDI channel number:
* When this message is received, the following controllers will be set to their reset values.
Controller Reset value
Pitch Bend Change +/-0 (center)
Polyphonic Key Pressure 0 (off)
Channel Pressure 0 (off)
Modulation 0 (off)
Expression 127 (max)
Hold 1 0 (off)
Sostenuto 0 (off)
Soft 0 (off)
RPN unset; previously set data will not change
NRPN unset; previously set data will not change
● All Notes Off (Controller number 123)
[GM2] [GM1] [GS] [AT]
Status 2nd byte
BnH 7BH
n = MIDI channel number:
* When All Notes Off is received, all notes on the corresponding channel will be turned
off. However if Hold 1 or Sostenuto is ON, the sound will be continued until these are
turned off.
● OMNI OFF (Controller number 124) [GM2] [GS] [AT]
Status 2nd byte
BnH 7CH
n = MIDI channel number:
* The same processing will be carried out as when All Notes Off is received.
● OMNI ON (Controller number 125) [GM2] [GS] [AT]
Status 2nd byte
BnH 7DH
n = MIDI channel number:
* OMNI ON is only recognized as "All notes off"; the Mode doesn't change (OMNI OFF
remains).
