It does look good. I've played with the demo for about 3 minutes now. Disappointed, though, that you can't create multisamples in it. You can save an sf2 or Kontakt file, etc, in its native *.bank format, but you can't create a bank from scratch, as far as I can tell.
Also lacking some valuable mods like velocity to sample-start, etc.
But it loads fast, and plays Kontakt files, etc well, without having to convert them. Nice to be able to open any sf2 or Halion file and be able to play it immediately. And it sounds good.
