I was thinking the same but then the other lesson his method suggests is that any sound can be turned into any sound so lets all stop worrying about it!
Phenomenally talented though and obvious phd level intellect. Can kind of fathom how he has used all that bespoke and off the shelf software and hardware to work together (I guess) but what I cant work out is that lack of latency in it all, which is only accentuated by his obvious musical chops.
If you watch long enough everything crashes which he also copes with quite well.
