* 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 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

* 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 [GM2] [GM1] [GS] [AT]

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 [GM2] [GM1] [GS] [AT]

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 [GM2]

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: 0H-FH (ch.1-ch.16)

pp = Program number: 00H-7FH (prog.1-prog.128)

* 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: 0H-FH (ch.1-ch.16)

vv = Channel Pressure: 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 3rd bytes

EnH llH mmH

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

mm, ll = Pitch Bend value: 00 00H - 40 00H - 7F 7FH (-8192 - 0 - +8191)

* 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 3rd bytes

BnH 78H 00H

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

* 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 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)

Polyphonic Key Pressure 0 (off)

Channel Pressure 0 (off)

Modulation 0 (off)

Expression 127 (max)

Hold 1 0 (off)

Sostenuto 0 (off)

[GM2] [GM1] [GS] [AT]

Status

2nd byte 3rd bytes

BnH 7BH 00H

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