Thank you Arwen, a brilliant evening, beautifully hosted and catered for by yourself (and I think with help from friends).
Thanks Czaba for an excellent outline as to how and what a sampler does to eventually produce a sampled organ. Particularly in this case the Esztergom.
Thanks to Gregory who provided us with a demonstration and the history of stops etc, from his early time on the real organ.
Stephen noticed a 3/4 violin belonging to Arwen's son, picked it up and, with a gentle accompaniment from Gregory on the Esztergom rendered a beautiful touching "Danny Boy".
All in all one of the best evenings I've spent for some time. Interesting how the Hauptwerk focus can create occasions!
