This looks GOOOOD. Some good basic functionality seems to have been added here. Mixer presets and drag and drop sounds sweet. Dunno if I like Halion much, but it's always good to have a sampler if you can't afford Kontakt!
I just wish they'd spend more money on developing the sequencer rather than adding more VST/ VSTis and let third party developers take care of it. I've never liked Steinbergs effects or instruments.
The new VST3 API is cool too. I hate having Kontakt/ Battery create 32 mixer channels - because they HAVE to in order to allow external mixing. Such a waste of resources... Can't wait for NI to upgrade the plugins to take advatage of them. I just wonder if they'll be willing to drop the VST2 API for backwards compatability's sake. Hopefully they'll release both.
All in all, it sounds like a worthwhile upgrade (not like last time)
