Go to 4:00 and watch to the end of the video. It does exactly what you want.
nix808. I was a diehard like you, unwilling to consider that Acid was decrepit, neglected laggard that was so far behind every other DAW it was holding me back. I was using Acid Pro 7 3 years ago and it hasn't improved simce then. My problem was that the only thing Acid does ok is making collages of loops and I was writing songs that required MIDI, VSTis, live instruments, etc. (It's not even good at making original loops, so pretty much all people do with it is stitch together loops other people produced.) I researched every DAW on the market and realized Acid was so far behind it was laughable. I had been wasting so much time. My music production skills have come lightyears. If you're just splicing loop libraries together, then maybe Acid is good enough. But if you want to actually compose music, work with live musicians, work with most of the newest VSTs and VSTis, forget it.
It sounds like I'm being mean, but I'm not trying to be I hope this will spur you to look at other DAWs--try Cubase or Studio One, for example--and you will PM me with a giant thanks
