the Rotterdam Laurenskerk main organ wet set is not encrypted. I made the GrandOrgue ODF for the dry version and originally wanted to make an ODF for wet at some point. But since there are now good free sets for GrandOrgue, I didn't do it. But you are welcome to take the Dry-ODF and convert it yourself. With the demo wet ODF you can see how this basically works. Of course it's a lot of work.
