The Quattro provides one (1) MIDI input and one (1) MIDI output. MIDI
operation on the Quattro is independent of the audio operation, and therefore
must be configured separately.
On the Mac, your music software has a MIDI device setup page. Open that page,
and click on the AudioSport Quattro “MIDI In” and “MIDI Out” devices to
select and enable them. As stated, the Quattro can be your only MIDI device, or
it can be used in conjunction with as many other MIDI devices in your system as
your music program allows. Your music software should allow you to arrange the
MIDI ports in a numerical order, according to your preferences.
The diagram below shows a typical MIDI setup involving the AudioSport
Quattro. Shown here is a controller keyboard plugged into the Quattro’s MIDI In
port, and a sound module plugged into the Quattro’s MIDI Out port.
