It’s true that you can dump a project into a git repo, but the real problem is diffing. It would be pretty miserable trying to reconcile any significant changes or conflicts. What I think would be cool is a tool for auditioning and merging specific changes that’s backed by git somehow. I’m not really sure what it would look like though.
In the mid-late 2000's, Ardour (and a couple of other DAWs) had support for branching undo/redo histories.
We (Ardour) abandoned it, because the universal experience of non-programmers was that they had no idea how to even begin to use this sort of feature. The majority of DAW users don't come ready to deal with the complexities of a branching workflow, or even a desire to learn it.
There is at least one band out of Madison, WI that uses/used git with Ardour during the height of the pandemic to facilitate remote collaboration on new pieces. They gave a talk (and played) at the Ubuntu Summit in Prague last year.
That’s wild, super cool that you guys were trying to make that work so long ago. I can see how people unfamiliar with that way of thinking would be completely lost. Especially in the context of a daw which is basically a wall of buttons and switches.
As a very entrenched Reaper user, I haven’t tried Ardour, but I’m glad it exists and continues to exist. Thank you for your work :)
