I don't know if you've all been watching this, especially with the news recently.
https://forum.cockos.com/showthread.php?t=202667 I tried the most recent Alpha and am able to effectively open up all my projects in Reaper (most recent update allows a successful translation of frozen tracks and synths). Just FYI. I don't know what I'll do in the long run, but it's been eye-opening to learn another DAW (or to try to, still a work-in-progress, quite a learning curve but maybe a useful one).
