I'm dusting off my old samplesets and I've found I have the files for St Maria Nordheim from Prospectum, but I no longer have the .organ file to get the Hauptwerk files to work with GrandOrgue.
Looking through the forum, I've found a few dead links, but the Filebase seems to be empty.
This thread looks promising, but my Deutsch ist nicht so gut:
Does anyone have a copy they could forward to me?
