I wonder, it there a way to build a phase correction in Logic or maybe I should re-phrase (no pun intended) a way to make a single track phase adjustable? I asked in reference to say microphones and even program material that might not be 100% in phase or 180 out for that matter. I m looking around for a phase correction plug-in that I believe exist for such a task but who knows, Logics environment can manipulate efx and inserts all sorts of ways. Just a thought.

Hey Victor, Logic's Environment wouldn't be so great for this IMHO... dealing with audio in real-time isn't it's forte. Although it's a long workaround, I prefer lining up waveforms... that's just me though! ;-)
