I love the workflow too, and it support mackie control, and can dynamically map anything to Kenton control freak, pc1600, bcf and about all available midi keyboard on the market. That's integration
It can also load about 45 synth + 40 effects @ 24/96 on my laptop without slowing down. Talk to me about optimized program.
I was like you Nestor, i tried reason v2 a long time ago, and didn't like the sound at all. But recently, someone showed me the new v3, and it sound alot more better.
You can almost master the complete song in it with the "m class" mastering effects included.
It's stability made me using it as the sampler here in rewire with nuendo (you can have 64 differents outputs to nuendo if you like) or a sound module for my external sequencer.
All my akai and sts program are already converter to reason's refill format.
Alot more efficient than using STS if you ask me

I still use sts5000 to build programs, but i quickly convert all of them to refills before really using them.
Reason v3 is good for what it was made. Very good in fact. I love it
