Thanks for sharing your workflow!! :)
Yes, it's a very good point about usually not needing to mix/automate the tracks before sending to Pro Tools for Mixing...
I have a very similar workflow, except I just solo the regions by selecting the track header (all regions within the cycle area on that track are automatically selected) press Option-Cmd-B for bounce and when done hit the down arrow...
But, I love the Solo lock... It's set as Option-S for me. But, I've never really used it before. I will now. Thanks!
Unfortunately, for John (Yadj) he has over 150 tracks to do, so hopefully Export all tracks as audio will work fine.
Oh, btw, your English is great Jobkey!
