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 IN MODE
Mode explanation
-------------------------------------------------------------------------------------------------------------------------
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/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.
-------------------------------------------------------------------------------------------------------------------------
The correspondence between channels and parts in each mode is described below.

■ 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.

------------------------------------------------------------------------------------
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.

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
from the Upper 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. 7).

[GM2] ... This indicates reception when GM2 Mode is enabled. To switch to GM2 Mode,
use GM2 System On (p. 5).
[GM1] ... This indicates reception when GM1 Mode is enabled. To switch to GM1 Mode,
use GM1 System On (p. 5).

GS Reset (p. 5).
[AT] ... This indicates reception for the keyboard part when MIDI IN Mode is set to
MODE 2. For more information about the keyboard parts, refer to the section on

n = MIDI channel number:
kk = note number:
vv = note off velocity:
* For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each
Instrument [GS].
* The velocity values of Note Off messages are ignored.
● Note on [GM2] [GM1] [GS] [AT]
Status 2nd bytes
9nH kkH
n = MIDI channel number:

* For Drum Parts, not received when Rx.NOTE ON = OFF for each Instrument [GS].
● Polyphonic Key Pressure [GS]
Status 2nd bytes
