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.
For information about TimeAdjuster in
Delay Compensation sessions, see the
Pro Tools Reference Guide.
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.
You can also compensate for offsets in-
curred by processing delays by using the
same plug-ins on all tracks.
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-
14 DigiRack Plug-ins Guide
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.
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.
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:
Start-Control-click (Windows) or Command-
1
Control-click (Mac) the Track Compensation in-
dicator for the Auxiliary Input to bypass delay
compensation.
Enter the total system delay into the User Off-
2
set field.
