Compensating for latency in Pro Tools LE and M-Powered
Because Pro Tools LE and M-Powered do not feature PDC it must be done manually when Duende plug-ins are used. Due to the use of firewire and the nature of how signals are sent to and from Duende, a latency is introduced which will delay any audio track, aux input, master fader or instrument track by a specified amount.
Tracks that use no Duende plug-ins or less than the track with the most Duende plug-ins will need to be delayed so they are all in time. Because this latency is reported by Pro Tools it is easily compensated for.
Here’s how:
The track with the most Duende plug-ins will introduce the most latency, those with 1 or 2 plug- ins will introduce less and those with no Duende plug-ins will introduce no latency (providing other plug-ins that introduce latency are not used).
To find out the latency introduced on a particular track by Duende plug-ins, go to the channel in the mixer and ‘COMMAND/CTRL+CLICK’ twice in the green text below the fader (normally showing vol). The value shown (dly) is the latency introduced on that track in samples.
Now load the ‘Digidesign Time Adjuster Long’ plug-in on, for example, a track with no Duende plug-ins. Double click on the delay box and type in the latency value of the track that has the most Duende plug-ins. The track with the most Duende plug-ins and the track with none will now be perfectly in sync on playback.
