No I can't slam Reason anymore! Those colab tracks have alot of Reason through them.
It's just the mixing engine which doesn't seem to work too well - export the tracks seperately and mix them somewhere else and it's great. Use it as an instrument instead of a multi-track recorder and it's all roses.
I think Live5 might fit into the same catorgory (from what I've read any way). I'll test the demo out soon.
Just one man's opinon. Sorry to all you Reason lovers out there.
