That's a really interesting piece you linked, thanks, and very impressive. I'm almost embarrassed to admit I could have mistaken (a couple of minutes of) it for some Sun Bear period Keith Jarrett! I couldn't make out how the piano sound itself is produced. Samples, I suppose, rather than some Pianoteq type modeling?
I don't know what is being used for sound generation. I don't know Max all that well, but blowing the video up to full screen, it looked to me as if it only generates MIDI. If that's correct, then I suspect either one of the modern sample-based pianos or pianoteq.
