Oh, thanks, that's interesting.
You are welcome. If you go the "Beauty in Sound" site on YouTube, you can see the whole concert from which the Nunc Dimittis is just one item.
It is interesting to see the development of these Hauptwerk organs. Richard loads sampling of different famous organs from time to time. The Salisbury organ is a recent Hauptwerk release and I understand is available in 10 channel format. I have always loved the Salisbury organ, and I think that is my favorite of Richard's so far.
It blows my mind that you can have vastly different organs from the same console, by changing the software.
I have been a sceptic of Hauptwerk, but I have to say, I don't think I could tell it was not a real pipe organ. This is his second Hauptwerk organ. The other did not have a natural bass and was not 100% convincing. The recitals on the original instrument are still up on Richard's site.
He does have a video of his building of a little Hauptwerk chamber organ. He does have videos of him playing other organs, including Romsey Abbey. He also has other notable organists playing his organ, including Anna Lapwood.
