I've been making all my stuff using Reason and am looking to upgrade to a ReWire host for it that supports audio tracks, tempo change, plug-in automation, etc. What are most of you using and why? Has any body used Mackie Tracktion? Since I'm not rich, that looks attractive, not to mention the 64-bit processing (for mixing "in the box"). What about Ableton Live, is that a good DAW for recording, or just performing? What are your thoughts?
