Real quick feedback on the Loopor plugin: I installed it, played around with it for 5 minutes all by itself (nothing else on the pedalboard), and tested the basic functionality on some very short loops (one channel). I was able to get it to work. I can hear a lightly audible pop at the end/beginning of each loop.
Frankly, as far as functionality goes, some sort of quantizing or BPM is really the only thing I can think of that I'd like to see when it's available (1.5?). You could stop developing this now and just address any bugs or stability issues that turn up, and I'd be satisfied- this definitely could be that simple version you mentioned above. The Duo should have a single button, no nonsense looper, so the second button can be used for something else, and Loopor does just that.
I'll try some more involved stuff with it in the coming days, with both channels (easy enough on a Chapman Stick) and on busier pedalboards.
Good work, thanks!!!
