Start recording on the ADAT, then click Play in
the Transport window in Pro Tools LE. When
playback is complete, stop both systems.
Monitoring Latency and Recording
Because Pro Tools LE uses the host processor in
your computer for audio processing, playback,
and recording, there is a small amount of audio
delay, or
latency
, when monitoring audio
through the system. You can set the latency to
be shorter when you are recording and monitor-
ing through Digi 002 or Digi 002 Rack, and
longer when you are trying to achieve higher
track counts with more plug-ins.
Set latency in the Playback Engine dialog. La-
tency is controlled by the H/W Buffer Size set-
ting, and is displayed in samples. The recom-
mended setting for listening back to audio is
512–1024 samples. For recording, when moni-
toring through Digi 002 or Digi 002 Rack, the
recommended setting is 128–256 samples.
To set the Hardware Buffer Size for record or
playback:
1
Choose Setups > Playback Engine.
2
Choose the number of samples from the H/W
Buffer Size pop-up, then click OK.
Low Latency Monitoring
Pro Tools LE includes a feature called Low La-
tency Monitoring for Digi 002 or Digi 002 Rack
systems. This feature allows you to use a built-in
mixer in the Digi 002 unit or Digi 002 Rack unit
to record and monitor up to 18 inputs (8 analog,
8 ADAT, and 2 RCA-S/PDIF) with extremely low
latency. This mode is useful for recording multi-
ple instruments at the same time.
To use Low Latency Monitoring, tracks must be
record-enabled, assigned to an actual audio in-
put (not a bus), and assigned to outputs 1 or 2.
To enable Low Latency Monitoring:
■
Select Operations > Low Latency Monitoring.
When Low Latency Monitoring is enabled, any
plug-ins and sends assigned to record-enabled
tracks (routed to Outputs 1–2) are automatically
bypassed, and must remain bypassed. Also,
these tracks will not register on meters for Mas-
ter Faders.
Recording MIDI
To configure a MIDI track for recording:
1
For Macintosh systems, choose MIDI > Input
Devices and make sure your input device is se-
lected in the MIDI Input Enable window. Click
OK to apply your changes.
2
Choose File > New Track and specify 1 MIDI
Track, then click Create.
For detailed information on connecting an
ADAT to your system, see “Connecting an
ADAT” on page 66.
