Having just bought VSL's totally fabulous and spellbinding Steinway D Full library (I think Paul was right - for me this is "The One!"), I realised I understood next to nothing about the craft and art of pedalling a concert grand.
Fortunately, to serve as an unofficial addendum to VSL's concise manuals for the Synchron Piano Player and the full Steinway-D, I found this YT video in which no less than 29 concert pianists shed light on the notoriously foggy topic of concert grand piano pedalling (apart from spelling the word wrongly in 'Murica *sigh*):-
