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. 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 (p. 1).

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.

UPPER 4
SOLO 1
------------------------------------------------------------------------------------
When SMF music data created using the AT-90SL/80SL 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 AT-
90SL/80SL is described below.

MIDI IMPLEMENTATION
GM2/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 AT-90SL/80SL’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 AT-90SL/
80SL’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

**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. 17) 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 AT-90SL/80SL, NRPN can be used to modify the following parameters.

**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

The System Exclusive Messages received by the AT-90SL/80SL are; messages related to
mode settings, Universal Realtime System Exclusive messages and Data Set (DT1).
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.)

GS Reset is a command message that resets the internal settings of a device to the GS initial
state. This message will appear at the beginning of GS music data, and a GS device that
receives this message will automatically be set to the proper state to correctly playback GS

Data transmission
AT-90SL/80SL can receive the various parameters using System Exclusive messages.
The exclusive message of GS format data has a model ID of 42H and a device ID of 10H (17),
and it is common to all the GS devices.
When keyboard part in MIDI-IN Mode: Mode-2, the exclusive message has a model ID of
62H and a device ID of 10H (17).
Data set 1 DT1
This is the message that actually performs data transmission, and is used when you wish to
transmit the data.
