Anybody using this in Acid? What a great feature! Yes, I know it's been around for a while but we just discovered it a while ago. Mostly, we produce 30 second and 60 second clips with no more than 6 or 7 tracks so there was little need to shove things around in groups. But then we put out some full songs for a retail album and this feature saved us a bundle of time. I thought we'd have to go back to school to figure out how to use it properly but the devs made this feature a no-brainer. We were up and running in ten minutes because we understood the behavior immediately. If you haven't used it yet, DO IT! Anyway, just wanted to rave about my favorite DAW. Yes, I'm a fanboy.
