You couldn't of posted that vid a few weeks ago? :)
Would have saved me quite a bit of wasted time adding Pro Tools to my mix environment.
I've experienced some of the gain-staging issues they talk about and have spent more time nudging tracks back and forth into time and/or calculating the additional manual delay-compensation to correct the flaws in what PT ironically calls AUTO-delay-compensation.
An example: I've got my buffer at 1024, mix some tracks. Switch buffer to 128 to record a few more tracks, drums and bass are no longer lined up. Line them up and record my tracks. Push buffer back to 1024 to avoid the dreaded 'overload' message. Guitar, bass, and drums are all out of time. Re-line up the tracks, rinse, repeat.
So far the best thing I've noticed about PT10 is the B3-Emulation is pretty killer. That's about it.
Just goes to show like I said in another post, the grass is not greener. I will say this though, I'd rather have an occasional crash here or there rather than to spend all my creative time on re-lining up transients.
