I think that his use of Logic in particular is very relevant in this discussion, because not only it has excellent support for different temperaments, it also has Hermut tuning, which dynamically alters temperament of all the instruments played based on actual chords to reach perfect intervals regardless of the key you're in.
Still, his virtuosity allows him to do things that very few people are capable of conceiving, attempting, and doing. We're lucky to have him in the mix.
