Interface: Very elegant, simple, nicely hi-tech looking interface. Separate pages for oscillators, filter/amp, lfo, midi/voices, fx and presets, fit into a nice step-by-step workflow.
Sound: Superb. I was most surprised by the thunderous bass this thing can get. Leads are musical and pleasing, pads can be lush and move in interesting ways over time...digital, analog, it really covers the basses very impressively.
Features: Many ways to manipulate sounds with your keyboard playing...changing time-stretch with velocity, lfo with aftertouch, etc...lots of nice, musical modulation possibilities.
I took away one point on features for lack of control of each of its oscillators' pitch. So, you can't harmonize a root and a fifth without stacking two instances of the synth and detuning one of them. The WAV import is a bit unpredictable, and seems to produce musical results only with a limited range of sounds.
Documentation: great manual, more than enough to teach you everything you need to know.
Presets: Great presets from many different sound designers. More than enough inspiring sounds to tinker with here.
Customer Support: Torben is tops. Any noticeable bugs were worked out within weeks of its release in a 1.01 update. Very active on KVR forum.
Value for money: Not the cheapest synth, but it certainly deserves to be in the price range that it's in.
