In regard to creating a license agreement for this conglomerate, I will contact Joseph Basquin regarding the 32' from the Jeuxdorgues2.
I think we should also approach Lars to see if we can release the Pitea, Kalvträsk, and Burea ranks as CC BY-NC-SA, Non-commercial. Most users will not be interested in downloading six sample sets and then trying to copy the correct ranks into a folder in order to use the Omni. It would be much easier to release it as a single package.
I was also unaware of the distinction between the two systems of combinations, I had thought that it was one system. So we'll need to fix the .organ definition in order to get the behavior that Ken wants for the combinations.
