Could you clarify the project's licence?

g'day,

I'd be interested in collaborating / testing to support more hardware
(PreSonus StudioLive 16.0.2 user here :) ), however it would be nice if the
licensing situation of the project was clear beforehand.

Right now there's no LICENSE file in the repo, which under GitHub's terms
defaults to "all rights reserved" — people can view and fork it here, but
can't legally build on it, modify it, or ship a derivative. That makes it
hard to justify sinking real time into a downstream layer.

Thanks for this great issue, that's important.

It's hard to say for now:

See, a lot of work is done by myself exploring the specs and translating it to the code. But I've used a lot of linux/Apple source code as references (without direct copying) too. Some parts, like your Presonus board will require some code snippets, research efforts done by linux enthusiasts and https://github.com/takaswie (until you are ready to do this work by yourself by analyzing packets from original drivers or reverse-engineering it). Apple's source/sample code is licensed under APSL 1.1, Linux - GPL 2.0 or 3.0, some of takaswie work you may need is under LGPL. So, that's somewhat a zoo.

Answering your question: I'm not a legal expert, but I see some licensing issues here. You should conceder my work licensed under MIT and kindly not copy-pasting stuff without putting original license to headers (that's not to you personally, general idea :) ).

TL;DR; staying open-sourced and not commercial I suppose we are able to make some reasonable stuff with proper license mentioning.

Seems that you've forked only main branch, and it's not good I would say :)
