TimeAdjuster
You can compensate for TDM or RTAS plug-in-
induced delays by using the TimeAdjuster plug-
in. This plug-in lets you apply a specific number
of samples of delay to the signal path of a
Pro Tools track. TimeAdjuster provides settings
files that apply the correct compensation time
in samples for delay introduced by one or more
plug-ins. See “TimeAdjuster” on page 90 for
more information about the TimeAdjuster plug-
in.
Manual Delay Compensation
You can manually compensate for processing
delay by first calculating the amount of delay on
each track, and then nudging other track’s play-
lists later or earlier in time. This method is useful
when Delay Compensation is unavailable, or
when you want to conserve resources.
Low-Latency Recording with
Instrument Plug-ins
When an Instrument track containing an in-
strument plug-in (or a MIDI track routing MIDI
data to an instrument plug-in) is record enabled,
Pro Tools automatically suspends delay com-
pensation through the main outputs of the au-
dio track, Instrument track, or Auxiliary Input
on which the instrument plug-in is
inserted
. This
allows for latency-free monitoring of the instru-
ment plug-in during recording.
MIDI and Audio Processing Plug-ins
Some plug-ins, such as Bruno and Reso, process
audio while allowing MIDI data to control pro-
cessing parameters. When you record enable an
Instrument or MIDI track that is controlling an
Audio processing plug-in, the track the plug-in
is inserted on will go into low-latency mode, ef-
fectively making the processed audio play early.
To keep audio time-aligned when using a MIDI
controlled plug-in on an audio track:
■
Start-Control-click (Windows) or Command-
Control-click (Mac) the Track Compensation in-
dicator for the audio track to apply delay com-
pensation.
To keep audio time-aligned when using a MIDI
controlled plug-in on an Auxiliary Input:
1
Start-Control-click (Windows) or Command-
Control-click (Mac) the Track Compensation in-
dicator for the Auxiliary Input to bypass delay
compensation.
2
Enter the total system delay into the User Off-
set field.
For information about TimeAdjuster in
Delay Compensation sessions, see the
Pro Tools Reference Guide.
You can also compensate for offsets in-
curred by processing delays by using the
same plug-ins on all tracks.
Delay Compensation for instrument plug-
ins 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 Re-
Wire to connect software synthesizers and
samplers.
