Connecting with External Devices
 
If You’re Using MIDI
 
 
 What’s MIDI?
 
MIDI stands for “Musical Instrument Digital Interface,” and 
is a unified standard for the exchange of performance data 
and other information between electronic instruments and 
computers.
The AT-15 is equipped with MIDI connectors to let it 
exchange performance information with external devices. 
These connectors can be used to connect the AT-15 to an 
external device for even greater versatility.
 
 
 About MIDI Connectors
 
The AT-15 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.
 
 
 
 MIDI Out Connector
 
The notes played on the keyboard, movements of the 
Damper pedal, Expression data, and data indicating that a 
Registration button [1]–[8] was pressed will be transmitted to 
the external MIDI connector.
 
 
 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-15 contains two sound generators: one sound 
generator for its own keyboards and one GS sound generator 
(p. 110). 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. 94) so that the keyboard sound generator is 
controlled.

* A separate publication titled “MIDI Implementation” is also 
available. It provides complete details concerning the way MIDI 
has been implemented on this unit. If you should require this 
publication (such as when you intend to carry out byte-level 
programming), please contact the nearest Roland Service Center
