After trying and failing to keep up with this thread (and the firmware releases), I accepted that I'm not really "experienced" with the MIDI Captain. But I am still a fan. :)
I was an early adopter and I still use mine daily. But I think the secret to my success has been the KISS method. I left mine in its default non-Turbo/ non-Genius/ non-whateverTFtheycallit mode, edited the text files as described to send PC/CC's as needed, and let all of the sophisticated work happen in the target device(s). As God intended. (If you buy, for instance, a $1500 modeler and a $150 foot controller, and then you try to make the $150 foot controller do the heavy lifting... you get what you deserve LOL.)
The only caveat to my "success" is that I haven't paid much attention to what the MIDI Captain's LEDs are doing as I mess around with Presets vs. Stomps vs. Scenes vs. Looper controls... My thinking is pretty much unidirectional: MC > QC. But I've learned the hard way (by growing old messing with these things), sometimes you just have to pick your battles. I simply mapped its switches to my QC's switches. I change modes via touchscreen or an unused switch as needed, and I play guitar. $150ish with wireless, rechargeable battery, 10 silent switches, and a couple of (admittedly laggy) expression pedal inputs. Good enough, and I hope Mr. Wilson is having a nice vacation.
A final note: I still think the text file editing - while kind of shockingly retro on first impression - is a fine solution. I've been through A LOT of these programmable footswitches and their pretty Windows and Bluetooth iOS editors, and they have ALL sucked in some little vexing way or another (usually pertaining to how they handle latching vs. momentary, or switch press vs. switch release), and they're all slower and more burdensome to use in practice, versus simply typing what I want into a text file on a nice big keyboard/ monitor. The MIDI Captain text files are very detailed and very explicit in terms of what their settings actually mean - provided you know MIDI well enough. And the fact that they're simple text files make it easy to backup, duplicate, and modify variations. Once you get past the "not shiny" vibe, it's actually highly practical IMO. (To play devil's advocate, maybe it wasn't documented clearly enough and it was just intuitive to me, for some reason, e.g. I'm a dinosaur LOL.)
