Hey
@christianhenson , I'd like to draw your attention to an "Organbook" of sorts.
piotrgrabowski.pl
This guy has been sampling pipe organs (some quite substantial ones too) around Europe for a while now, and all but a few of them are available for free. When I say sampling pipe organs, I mean immaculately, pristinely, and gorgeously sampling pipe organs. It's incredible stuff and unspeakably generous.
The main caveat is that these are not EXS (Dave?) or Kontakt instruments. They require either the rather pricey Hauptwerk, or, more palatably, the open source version of that software, Grand Orgue. Neither is especially ergonomic to a DAW workflow, but given the amount of passion and skill that obviously goes into these instruments, I thought they would be worth bringing to the attention of a community like Pianobook, for those who might be interested in the piano's extravagant grandfather.
