Ok, here's my take.
Time got away from me and it's been at my place for far too long. Will send it to the next homie asap.
Expression multiplexer:
I had fun using this pedal!
I am pretty bone headed these days and I didn't really understand setting saving and whatever. The way I was using it seemed to be channel 1 plus 1 other channel, which I could select.

The range on the digital pots was good and I could get some really cool sounds out of it.
The interface was simple, which is good, but I'm trash with secondary functions, saving stuff and whatever. This is one of the reasons I've gotten rid of the Ct5. I just couldn't remember what was happening with what. So I'm going to say that it was a super nice pedal, suited to a person who is more prepared to spend time understanding stuff
Here is a short demo of some fun sounds I got with this duder:

Bacon Boost.
It boosted. It was fairly loud, not excessively so. I didn't get much mileage out of the clipping diodes, which was a bit of a bummer. Could be user error. Would like to try stacking two of them, I reckon you could get a pretty rad overdrive out of it.
The synth:
Anyone who has read any of my posts ever knows what I think about synths hehe.
After incorrectly using this as an expression generator, and not frying my pedals, I then unplugged the guitar and used it as a synth. I don't know what the hell I was doing and I made some noises. So...

?? I think the LFO, or one of the things that made something happen, could go slower to get a real slow evolving sound. I'm not sure of the intended market for this thing, but I dunno if it would would be interesting to have an audio in so that I could shred with the drones. Dunno who'd listen to that though. Probably not me so this isn't a great idea.
The build quality is rad on all the pedals. In terms of protos, they are outstanding. This will sound stupid, but for example the diode switch on the Bacon was easily the best I've tested/used - it felt incredibly solid and nicely machined - often these switches can feel a bit flimsy or loose. The minimalist aesthetic is nice, but quite utilitarian. If and when these go into production then I'd like to see something a little more obviously
designed - the font nerd in me for example got a bit crazy over seeing three different fonts on top of each other on the Bacon
Thanks for letting me test out this stuff and give my uninformed opinions!
Gonna get this boxed up and sent out.
Sorry for letting time get away from me and for hoarding the tour box for as long as I did.
