I know some might not like it/use it but the new beat detective... er drum editing deluxe looks AWESOME.
I thought the groups thing wasn't all that impressive, just a way to not forget to select all events to cut etc...
Amp rack isn't something I would ever use, but it's good they added it.
I think Halion one sucks ass as far as the interface and GUI goes so anything they do to make that better is a plus in my book, and they did so yay neat.
The new faders looks stupid, I like the current ones. Wish they didn't change that.
Note expression: Just one more thing that makes cubase the midi master DAW that it is (IMO of course)
Scaling tools for automation is a freaking godsend, that is one of my favorite things in pro tools and they added that kind of style to
cubase 6. Amazing new feature IMO.
Plus I have heard that you can now have triplet lines in edit window, another awesome new feature.
All of that is enough to get me to eventually upgrade, but in the past Steinberg has done a terrible job beta testing their software and the first versions always seem to be really buggy so I'm holding off for a bit before I upgrade.
