The other is the actual MIDI performances. Almost all performers copyright their MIDI files, using the argument that they are an original performance of a classical work.
I'm not sure how MIDI works. If you give two MIDI composers the exact same sheet music, would there be differences in the files they generated? In other words, does they basically just enter the sheet music and a music file comes out, or is there a task of arrangement that produces a unique file no one else could create exactly on their own?
If there are going to be legal issues to deal with that would prevent PG from accepting the files because of possible clearance issues, I probably won't bother.
One of the posts in one of these threads spelled out exactly what PG requires, perpetual, global, yadda yadda (sorry, I don't remember, and I've deleted the e-mail.) You should look for that, or maybe someone can repost it. Then, you could show the composers, say this is what you would have to grant in your license for PG to use it, and they could give you an answer then and there. PG is noncommercial but not personal, so it sounds like their current terms wouldn't work, unless they were willing to amend. Dave Doty
