Thomas,

Umm.. you sound a bit upset, not sure if you are as that's always difficult to see on someone's reply.

The reply from DAW couldn't be different really as you are targeting a private interface. If they are publicly discussing how to use it then they'll end up having to support it.

You've got an interesting project on your hands btw.

Anyways, my advice to you is to contact DAW directly by email or by phone and not in a public forum.
They might want you to sign an NDA etcetera and still give you the "no guarantee that we won't change the interface" comment.

But you're much more likely to get tips or anything in this regards. Although I can't speak for DAW, I would certainly try it via that route.

Good luck!
