Low Latency Monitoring During
Recording
For recording, Pro Tools automatically suspends
Delay Compensation to provide a low latency
monitor path through the main outputs of the
record-enabled tracks. When an audio track is
armed for recording (in stop), TrackInput-en-
abled, DestructivePunch-enabled, or punched
in, the track’s Delay Compensation is automati-
cally suspended (and the Track Compensation
indicator displays 0).
You can suspend this automatic suppression of
Delay Compensation as needed by doing the
following:
To apply Delay Compensation to tracks where
Delay Compensation was suspended:
■ Start-Control-click (Windows) or Command-
Control-click (Mac) the Track Compensation in-
dicator. Track delay will be applied to the track
and the Track Compensation indicator will dis-
play in blue.
Track Compensation on Auxiliary Inputs
Delay Compensation on Auxiliary Inputs can be
bypassed to let you monitor outside sources
(such as the audio tracks of a slaved video deck)
with minimal latency, while still reporting the
track’s delay.
To bypass an Auxiliary Input’s Delay
Compensation:
Start-Control-click (Windows) or Command-
Control-click (Mac) the Track Compensation in-
dicator. The reported track delay will be zero,
and will appear greyed out.
Delay Compensation for MIDI
When Delay Compensation is active, a MIDI
event that is recorded to sound “in time” with
delay-compensated material actually is recorded
late by the length of total delay in effect.
To compensate, MIDI events are shifted back in
time by the total session delay following each
MIDI recording pass.
Low-Latency Recording with Virtual
MIDI Instruments
When a MIDI or Instrument track that is routing
MIDI data to an instrument plug-in is record-en-
abled, Pro Tools automatically suspends Delay
Compensation through the main outputs of the
audio track or Auxiliary Input that the instru-
ment plug-in is inserted on. This allows for la-
tency-free monitoring of the instrument plug-in
during recording.
Delay Compensation for virtual MIDI in-
struments works only when all MIDI and
audio connections take place inside of
Pro Tools. For example, Pro Tools does not
suspend Delay Compensation when you are
using ReWire to connect software synthe-
sizers and samplers in other ReWire client
applications (such as Live and Reason).
