It's an interesting product. Instead of digital oscillators at 44khz, based on a FPGA rather than a DSP (very cool)! These run at 24Mhz over 500x faster than typical digital oscilators, so no aliasing, pretty much indistinguishable from analog.
Filters are analog, and also the analog signal runs in parallel to the digital FX (speaking of which, the reverb is amazing).
$1300 isn't cheap though, and I wonder how they will make out on sales at that price point. In terms of my own taste, it doesn't sound bad but the softsynth world has spoiled me with regard to my preference of using knobs for ADSR envelopes versus sliders. Sliders are nice in that they give a visual of the envelope, but I still prefer to work with knobs, and with soft synths I get the best of both worlds since the VST display gives me a good visual of what I'm doing in real-time and a snap shot of where the envelope is.
