Plug in an external interface (like basically everyone does) and it has
a midi connection. Also, jack doesn't need a midi hardware device to be
useful.

I'd worry about left/right buttons first, find agreement on basic stuff,
worry about the leftovers later.

Yes, I'm also very much pro a convention. I don't see any real solution
to the problem that different human interface guidelines create in
general, and it's a real mess on linux or when you want to go cross
platform, but a convention for Linux Audio sure wouldn't hurt.
