Here's where it got interesting...when I played the recording back from the beginning of the drum track, all the tracks played in sync. If I stopped the recording after the verse and tried to start replay from the verse position, the drums immediately were out of sync - while the guitar and bass were still in sync with each other just out of sync with the drums. I talked to AVID tech support, I came down here to the DUC to get some help (they tried valiantly but no luck) and I reached out to several audio tech gurus I've known for many years here in LA - none could solve the mystery no matter how many work arounds were suggested and tried.
At the end of the day I could not figure out why the tracks would be "in sync" if I started the recording from the beginning but out of sync if I started it anywhere else in the recording. I narrowed it down to 2 possibilities: 1. I had somehow accidentally "marked" a different time signature on the drum track using the search marks, but failed to do so on the accompanying instrument tracks 2. the "composer" button (on the transporter) was engaged causing playback/timing issues.
I have no idea if those were the reasons for the out of sync issue, but the good news is that as soon as I learned a little more about how to set up and use PTs properly I have had zero sync issues on some 20 sessions since the first fubar session.
Make sure you have your session set up properly - there are many variables involved. As an exercise you might want to do several practice sessions using the session templates. The templates take some of the guess work out of the set up. I would also strongly suggest you get a book like Ignite or any other support material you can find and read as much as you can about setting up your session. The learning curve is sometimes arduous in PT and since you're using 11 you might have to wait a few weeks for commercial manuals and support materials to become avail. I would use materials from 9 or 10 to help navigate the basic parameters which should be similar to 11.
Good luck.

I think you're definitely on to something. Honestly, I probably don't know what I'm doing. Because of the frustration caused by this sync problem, I've been hesitant to start diving into Pro Tools guides, because I've felt that I should have the software working perfectly first, but the problem could likely be the result of an improper setup. Currently, I'm reformatting my desktop and slapping fresh copies of Windows and Pro Tools on there. This should hopefully rule out any bad install or broken plugin type causes. I also just purchased
Pro Tools 10 Ignite Kindle Edition, and I plan to start reading through that while I wait for all my drivers and software to install.
Thanks for the advice. Whether or not it fixes my bizarre sync issues (and I think it likely will), I'm sure this book is going to really improve my understanding of Pro Tools.
