Interesting.
This video also provides some insight into an earlier question — which was why McVeigh's sample set(s) sounds different (or better, I think was the description?) from the same sample set when played locally on the questioner's organ (sorry, I've lost track of the original post, and don't recall who asked the question).
It's clear, with one brief exception in the video where you do very briefly hear the dry Prib au naturel, that the video recording had considerable added reverberation and/or other processing. I suspect there may be similar audio post processing in many of his videos, which could explain the differences. I'm not saying that's a bad thing necessarily, just that it can make a sample set sound considerably different than the same set played in it's original recorded form straight from Hauptwerk in your living room or on headphones.
