The versioning idea is interesting and something many musicians have to contend with as they work on songs. Personally, I wouldn't want the complexity of take-level versioning, but pinning audio and mix automation to a given mixdown could be useful for tracking the history of a song. It might be more effective to approach this as version tracking / collaboration layer around existing DAW formats rather than a full replacement.
Does it support VST, AU? Any support for midi? Which OS’s supported?
Is this just a multi tracker recorder that has a git style storage?
I'm adding additional support for loading plugins. Eventually, I would like to add VST support but that's down the road a bit.
It has basic midi support, can use a controller, or edit with keyboard.
in the context of computer-based recording it's pretty common jargon
I’m not expecting a whole Ableton replacement, but things like hosting plugins and working with MIDI is IMO fair to expect from any piece of software that wants to call itself a DAW.
REAPER’s project files are all very git friendly.
Simple add/commit/push, etc. Of course, if you’re going to be sharing a REAPER project in a repo, you should enable LFS, and have a smart project structure for your works. If collaboration through a repo, with tagging and branching, is part of your setups workflow, this already works quite well with REAPER projects.
However, I have to say that since REAPER allows full control over literally years of recording sessions, the whole concept of having the ability to go back and forth through different versions of the art—form being recorded (music, vocals, etc.) is already well provided in REAPERS sample-accurate ‘reflog’.
;)
Honestly, as long as it's based on open, text-based formats, I could handle the Git part myself.
