UAD Powered Plug-Ins Manual - 57 - Using UAD Powered Plug-Ins
Let’s say you have a MIDI track and an audio track with a UAD plugin on the
audio track insert. In this scenario, the host application will automatically
compensate for latency and no use of the UAD DelayComp or UAD Track Ad-
vance is required.
However, if the audio track is sent to a send/group/bus and that
send/group/bus has a UAD plugin on it, the audio track will be delayed in
relation to the MIDI track because the host does not compensate for latency
automatically on groups/buses (unless full-path latency compensation is im-
plemented in the host). If the MIDI track was an audio track, you would use the
UAD DelayComp on it to compensate for the latency. But you can’t put a UAD
DelayComp on a MIDI track, so what to do?
Enter the UAD Track Advance plugin (TrackAdv for short). It operates just like
the DelayComp plugin, but backwards. Instead of delaying unprocessed
tracks, it shifts them forward. It does this by reporting to the host application
that a track has a UAD plugin on it, so the host compensates for the latency.
However, the track audio is not actually processed by the UAD so the net re-
sult is that the audio plays early.
Note: The Track Advance plugin only works in hosts that support partial
(track inserts only) automatic delay compensation.
When to use
TrackAdv
UAD TrackAdv should be used whenever MIDI tracks are played alongside
audio tracks that are assigned to a send/group/bus that is using UAD plu-
gin(s).
Important: UAD TrackAdv should not be used in host applications that pro-
vide full plugin delay compensation throughout the entire signal path. UAD
TrackAdv or DelayComp is not needed at all in such hosts. See “Host PDC Im-
plementation” on page 46.
How to use
TrackAdv
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 plugins 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 plugin, the “net latency
result” is zero and the audio will be perfectly aligned with the MIDI tracks.
