Audio clip loading Mp3s made it worth the purchase for me. Seems like a basic thing, but gives me all the things I liked about being able to load a sample into edison/FL inside Reason.
Sampling has always been my big headache with Reason. Never used recycle, had to open a seperate loop editor, now i can sample 100s of different ways between the upgrade from 5-7. That's alot of ground covered in a short time.
I still hate the changeup in the mixer, but the new routing and faders built in to the instruments help alot as well. I don't have to full screen and bounce all over the place anymore. Gone back to a minimized screen and just go to the mixer on the rare occasion I need to do more than adjust gain and pan(similar to why you'd go to FL's mixer). Reason has become a well rounded program. I could use it from the beginning to the end of a project now, kind of how i used SONAR on PC.
Alot of guys say this is a weak update, but from an engineering and sampling perspective, it opened a new world. Midi Outs are awesome as well, make me wanna pick up some hardware in the new future. Been playing with it with the few modules I have, just that they don't benefit as much as hooking up something like a newer workstation keyboard or modular synth.
First time in the last few updates I haven't been upset by "what's new". Mainly because for once, they didn't change anything and expect me to change my workflow because they said it was better.
