Chapter 10 Connecting with External Device
Connecting MIDI Devices
By connecting an external MIDI device and exchanging
performance data, you can control the performances on one
device from the other. For instance, you can output sound
from the other instrument or switch Tones on the other
instrument.
What’s MIDI?
MIDI, short for “Musical Instrument Digital Interface,” was
developed as a standard for the exchange of performance
data between electronic instruments and computers.
The AT-90S/80S/60S is equipped with MIDI connectors and
a Computer connector to let it exchange performance data
with external devices. These connectors can be used to
connect the AT-90S/80S/60S to an external device for even
greater versatility.
About MIDI Connectors
The AT-90S/80S/60S has two kinds of MIDI connectors.
Connecting these to the MIDI connectors on a MIDI
instrument makes it possible for the two instruments to
control each other.
For instance, you can output sound from the other
instrument or switch tones on the other instrument.
You should also set the MIDI send channel as needed.

MIDI Out Connector
Only the notes played on the keyboard, movements of the
Damper pedal, Expression data, and data indicating that a
Registration button [1]-[12] (on AT-60S, Registration [1]-[8])
was pressed will be transmitted to the external MIDI
connector. The Solo voice will be transmitted only if the Solo
[To Lower] button is ON.
MIDI In Connector
Performance messages from an external MIDI device are
received here.
These incoming messages may instruct the receiving MIDI
instrument to play sounds or switch tones.
The AT-90S/80S/60S contains two sound generators: one
sound generator for its own keyboards and one GS sound
generator (p. 213). Normally, musical data transmitted from
an external device to the MIDI In connector is sent to the GS
sound generator, but you can also set the “MIDI IN Mode”
parameter (p. 173) so that the keyboard sound generator is
controlled.
Making the Connections
NOTE
When connecting, turn on power to your various devices in
the order specified. Failure to follow these steps in the order
given could cause a malfunction and/or damage to speakers
or other equipment.
1. Turn the volume all the way down on the AT-90S/
80S/60S and on the device you’re about to
connect.
2. Switch off the power to the AT-90S/80S/60S and
the device you’re about to connect.
3. Set the Computer switch on the bottom of the
unit to “MIDI.”
4. Use a MIDI cable (sold separately) to connect the
MIDI connectors to each other.
5. Switch on the power to the AT-90S/80S/60S and
the connected device.
6. Adjust the volume level on the AT-90S/80S/60S
and the connected device.
7. You should also set the MIDI send channel as
needed.
