UAD Powered Plug-Ins Manual v5.2 - Just Music

How to use
TrackAdv
Plugs parameter
UAD TrackAdv is designed to be used on audio track inserts of tracks that are
assigned to a send/group/bus that has one or more UAD plug-ins applied.
By first advancing the audio with TrackAdv on the track insert then processing
the same track on a send/group/bus that has a UAD plug-in, the “net latency
result” is zero and the audio will be perfectly aligned with the MIDI tracks.
The TrackAdv Plugs parameter value to be used on a track insert is simply the
number of UAD plug-ins that are being used in sequence on the send, group,
or bus that the track is assigned to.
For example, if three separate sends are used and each send return has one
instance of UAD plug-ins, the TrackAdv plug-in value for the audio tracks insert
would be one. However, if one send/group/bus is used that has three instances
of UAD Powered Plug-Ins stacked up, the TrackAdv Plugs value for the
tracks inserts would be three.
Note: The TrackAdv “Plugs” value on the track insert matches the total of
UAD Powered Plug-Ins used serially (stacked one above another in series) on
the send/group/bus that the track is assigned to, NOT the total number of
UAD Powered Plug-Ins used.
Samples
parameter
The Samples parameter shifts the audio with single-sample accuracy in either
direction. It is provided mainly for compensation of the upsampled UAD plugins
(“Compensating Upsampled Plug-Ins” on page 97). However, it can be
used anytime minute shifting of audio is desired. Audio can be shifted up to
128 samples in either direction.
Note: The keyboard shortcuts PageUp/PageDown and Shift+Arrow automatically
add the 13-sample Pultec value for your convenience.
TrackAdv Examples
Insert
Situation: You have one track with MIDI and one track with audio. You put a
UAD plug-in on the audio track. Result: All tracks are perfectly aligned.
Solution: None needed. Delay compensation on track inserts is handled automatically
by most host applications.
Send
Situation: You have a song with drums and guitar on audio tracks, and a MIDI
bass line. You want a cohesive room reverb on the audio tracks so you send
them to the UAD RealVerb Pro via an effect send. Result: The RealVerb Pro effect
return plays late in relation to the MIDI track.
