I'm working on a feature film in Pro Tools 8 LE on my Macbook. There's a scene in where I'm automating a reverb plug-in on my dialog aux, due to the characters going in different rooms down a long hallway, in one single take. About halfway, my automation stops reading correctly and when I go back earlier in the scene after it stops reading, all of the parameters for the plug are all wonky. It's only until I go to a different point in the timeline or just relaunch the session, where everything is okay until it gets to the same point. What is causing this and what should I do?
Shot in the dark, are you using D-Verb? I've ran into this many times and eventually just stopped using the plug because of it. It's a known bug that sadly seems to have been around a long time. I'm pretty sure it's switching either the algorithm or the size that screws things up.
Find another reverb you love and don't look back IMO.
