Hello sfpuppy,
The sample set creator's guide that we sent you previously covers the entities in the 'full' organ definition format. (Except to major commercial sample set producers) I'm afraid we don't officially provide support with editing or using that format, though (effectively it's a complex programming language) -- sorry. We only officially support using the Custom Organ Design Module (CODM), which is intended to be relatively easy for technically-inclined people to learn and use, whilst being sufficiently flexible to create sample sets suitable for personal use and/or commercial release.
Hence you're welcome to try using the full format if you want, but we wouldn't be able to help you with it -- sorry again.
