1. Receive Channel
■ Performance Parts and Transmission Channels
This instrument contains two sound generators: one for SMF data playback (GM2/GS) and one for
keyboard performance. Normally, data received at the MIDI In connector will control only the
sound generator for SMF data playback. However by changing the MIDI IN Mode setting, you can
also control the keyboard sound generator from MIDI In.
For instructions on changing the MIDI IN mode, refer to the Owner’s Manual. For instructions on
controlling each sound generator, refer to the “Received data” section.
* In this document, the Music ATELIER AT-900/900C/800/500/300/100/75 models are collectively
referred to as “the ATELIER.”
❍MIDI IN MODE
Mode
MODE 1 Control the instrument as a GM2/GS sound generator.
MODE 2 Channels 5 through 10 and Channels 12,14,15 are transmitted to the GM2/
The correspondence between channels and parts in each mode is described below.

* The AT-300/100/75 do not have Manual Percussion.
■ MIDI Channels on SMF Music Data
This instrument contains two sound generators. Commercial SMF music data is played back using
the GM2/GS sound generator. The correspondence between channels and tracks when the AT’s
Track Mute function is used is described below.

ACCOMP 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16
BASS 2

UPPER 4
SOLO 1
When SMF music data created using the ATELIER is used, the parts of the performance played by
hand are transmitted to the sound generator used for the keyboard performance, and the
automatic accompaniment portions (rhythm performances, Arranger) are transmitted to the
GM2/GS sound generator.
The correspondence between channels and parts for SMF music data created using the ATELIER is
described below.

Explanation
GS sound generator, and all other channels are transmitted to the
keyboard sound generator. When the Pedal part tone has been selected,
Channel 2 is transmitted to the sound generator used for the keyboard
performance; if no tone has been selected, it is transmitted to the GM2/GS
sound generator.
2. Transmit Channel
■ Keyboard and Transmit Channel
You can control external MIDI devices using the ATELIER’s MIDI Out connector. Data describing
what is played on the Upper keyboard, the Lower keyboard, and the pedalboard is transmitted
over MIDI channels for the respective parts. Messages from the ATELIER’s expression pedal and PC
Numbers set in the Registrations are transmitted on the Control channel. The channels used for
transmission can be changed individually for each Registration. For instructions on how to change
the transmission channels, refer to the Owner’s Manual.
Channel (default) Content Transmitted
Upper (4) Key information from the Upper keyboard is transmitted.
Lower (3) Key information from the Lower keyboard is transmitted.
Pedal (2) Performance information from the pedalboard is
transmitted.
Solo (1) When “Solo to Lower” is set to ON, Solo part key information
from the Lower keyboard is transmitted.
Control (16) Expression pedal information and PC Numbers set in the
Registrations are transmitted.
* The PC Number is transmitted when Send PC Switch is set to ON.
* For more details regarding the data that is transmitted, refer to “Transmit data” (p. 8).
3. Receive Data

mm = upper byte of the parameter number specified by NRPN
ll = lower byte of the parameter number specified by NRPN
* NRPN can be received when Rx.NRPN = ON. “Rx.NRPN” is set to OFF by power-on reset or by
receiving “Turn General MIDI System On,” and it is set to ON by “GS Reset.”
* The value set by NRPN will not be reset even if Program Change or Reset All Controllers is
received.
* Not Received in Keyboard Part.
**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended range of control
changes to be used.
To use these messages, you must first use NRPN MSB and NRPN 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 NRPN 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. Supplementary material “Examples of actual MIDI messages”
<Example 4> (p. 18) On the GS devices, Data entry LSB (llH) of NRPN is ignored, so it is no problem
to send Data entry MSB (mmH) only (without Data entry LSB).
On the ATELIER, NRPN can be used to modify the following parameters.
NRPN Data entry

* Relative change parameters will adjust the value relative to the preset value as the center
(40H). Even for GS compatible devices, a relative change parameter may have a different range
of change or affect the sound in a different way depending on the model of device.
* Absolute change parameters will specify an absolute value regardless of the preset
value.
❍RPN MSB/LSB (Controller number 100, 101)
Status 2nd bytes 3rd byte
BnH 65H mmH
BnH 64H llH

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. 18).
On the ATELIER, RPN can be used to modify the following parameters.

●System exclusive messages related to mode settings
These messages are used to initialize a device to GS or General MIDI mode, or change the
operating mode.
When creating performance data, a “GM2 System On” or “GM1 System On” message should be
inserted at the beginning of a General MIDI score, and a “GS Reset” message at the beginning of a
GS music data. Each song should contain only one mode message as appropriate for the type of
data. (Do not insert two or more mode setting messages in a single song.)
