Chapter 4: Connecting Your Studio 41
MIDI Connections
Using the Digi 001’s built-in MIDI ports or an external MIDI Interface, a MIDI keyboard
controller and MIDI instruments, you can take full advantage of the MIDI features of
Pro Tools LE. These include recording and editing MIDI tracks, synchronizing to MIDI
Time Code or MIDI Beat Clock (this requires an appropriate MIDI interface) and using a
MIDI control surface.
To connect MIDI devices:
1 Using standard 5-pin MIDI cables, connect the MIDI OUT of the MIDI device or
controller to the MIDI IN of your Digi 001 I/O Box.
2 Connect the MIDI IN of your MIDI device or controller to the MIDI OUT of the Digi 001
I/O Box.
3 Connect the audio outputs of your device to the audio inputs of the Digi 001 I/O Box (or
to an external mixer if you are using one).
☞ For information on configuring OMS (Open Music System), which is required by
Pro Tools LE on the Macintosh, see “Installing and Configuring OMS” on page 9.
☞ For information on configuring a MIDI control surface for use with Pro Tools LE,
see the Pro Tools MIDI Controllers Guide .
Using External Effects Devices
The Digi 001 allows you to create dedicated connections to external analog or digital
devices. You can send and return signals to analog devices using the analog inputs and
outputs on the Digi 001 I/O Box. You can also send and return a digital signal to an
external device that supports digital I/O (such as a reverb unit), and monitor with the
analog outputs or (if unused) the other digital output.
If you want to use the digital inputs and outputs on your Pro Tools LE system as effects
sends and returns to a digital effects device, Pro Tools LE should be the clock master in
most cases. Set your digital effects device to accept an external digital clock so that it
synchronizes to Pro Tools LE.
