First impressions of Ableton 7

So I got Ableton Live 7 downloaded and installed. It updated my library and so far it opens all my old projects from version 6. Here are some of the highlights:

• Import audio loops to midi track! It slices the loop into a drum rack and creates a midi track for it. Try throwing midi effects on that!
• New compressor w/ sidechain had me tweaking my kick and bass to pump and breathe.

I'll be testing it out with another Ableton 7 user this week so midi sync and live set exchange will be tested later.
