Have tried the demo for a while. It has quite an interesting sound, what you might imagine an EMS vocoder to sound like, very gritty. however for the asking price i didn't find it that flexible... i would have liked an emulated analogue drive option and perhaps some more flexibility for the folter bank. The user interface is also a bit of a pain - it's vertically bigger than my screen. There's a demo on the site - check it out.
