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 4. "Examples of actual MIDI

messages" <Example 4> (p. 12).

On the AT-S, RPN can be used to modify the following parameters.

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. (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.

* For Drum Parts, Program Change messages will not be received on bank numbers 129-

16384 (the value of Control Number 0 is other than 0 (00H)).

* When MIDI-IN Mode = Mode-2, it should be used System Exclusive messages to change

the voice of keyboard part.

* Not Received in Keyboard Part.

Explanation

Pitch Bend Sensitivity

mm: 00H-18H (0-24 semitones), Initial Value =

02H (2 semitones)

ll: ignored (processed as 00h)

specify up to 2 octaves in semitone steps

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)

specify up to 2 octaves in semitone steps

Refer to 4. Supplementary material, "About

tuning" (p. 13)

Master Coarse Tuning

mm: 10H - 40H - 70H (-48 - 0 - +48 semitones),

Initial Value = 40H (0 cent)

ll: ignored (processed as 00h)

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.

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. (Initial value is ON)

* The resulting effect is determined by System Exclusive messages. With the initial

settings there will be no effect.

* The initial setting of Keyboard part is Vibrato depth. It can not be changed.
