I’ve been using git for remote collaboration music production for 5 years. We sometimes use branches as well when we are working in let’s two ideas for a bass line. We’ve not really had any issues other than that we need git lfs.

The workflow is based on having the same software, ableton and plugins are largely mirrored.

We communicate over FaceTime which is good enough to assess ideas. When then record track for track and build the songs that way.
