automatic delay compensation question

[anth]

Is the delay reading of a plugin in pro tools 10 still meant to be the same when ADC is on or should it be zero e.g. I have a lexicon reverb plugin that incurs a delay of 32 and when ADC it still says there is a delay of 32 in the track?

The reason I ask is because after lining up two tracks (seperate mics on a guitar cab) to sound good, when I have the plugin on one of the tracks (bypassed)... the alignment goes off (i.e. there is a delay between the tracks and I hear comb filtering effect). ADC should be compensating for this ? I tried setting the ADC to short and long and had the same problem.

ADC can't change the built in delay of the plugin. All it does is delay the other tracks the same amount to match it.

Sounds like a good reason to put delay and reverb plugins on AUX tracks and send to them, keeping them set to 100% wet mix. That way you never combine dry signal from 2 tracks, avoiding any comb filtering.

It's supposed to compensate for any inserted plugs as well so it should be bumping the other tracks back. Another thing is I find that with certain plugs, I have to completely take them out of the chain so there is no latency. If I just bypass, I still get the latency from the plug. If I remember right, one plug may have even caused a latency while in an inactive state!

Actually, most or all plugins will cause latency while bypassed(you would not want that to change if you automate the bypass). ADC is not quite perfect, and it only takes 1 sample to cause comb filtering between identical signals. I have never had an issue with 100% wet verbs and delays on AUX tracks
