I use Git with Lilypond[1], text-based music notation software: https://lilypond.org/

It's akin to working in LaTeX with Git, in that there's a source file that gets tracked, while the PDF output is untracked. And it's great because this is real source code and the Git diffs and commits are meaningful, unlike working in binary formats.

I feel fairly confident that decades from now my work will be recoverable, a confidence that I don't have when working with proprietary binary formats.

What options do I have for text-based DAW? I accept that this is a niche preference for solo work; I have difficulty imagining that such a platform would be suitable for traditional studio collaboration. I've dreamt about building something myself using AES31 if I only had another lifetime — but maybe someone has beaten me to it?
