Okay, spammed* as many audio related forums and mailing lists as I could think of where I actually use their stuff or where there might be general interest about my musical stems file format for DJing and tracks meant for re-mixing. It's such a niche thing that I have received very little feedback so far, but if you can think of anyplace that might be open to providing feedback (ie. DJ applications like Mixxx or DAWs like Ardour who might want to implement the format in the future), let me know so I can ask if they're willing!

* With a relevant ask for help from potentially interested stakeholders.
