I love Reason - but for production and sound design, didn't finish any mix there... But it is so cool now to have all the VSTs there - synths, tape machines (Reason really missed those), eqs, compressors... I already have beta installed and it works pretty good (and UAD works well there). With 8 CV inputs per VST you can modulate lots of stuff. And with Reaktor and Softube Modular VSTs combined with Reason REs you can do so many crazy modular things, I'm really excited about this update!
It seems that with new investors they just started developing users most requested features: sample import for REs [done], VST support [done] - I'm wondering what's next?
