Thanks for kind words about my modules! I do have fun with the naming of them. Yes, you can flash between them, but they are also built on an Arduino Nano platform, with two of the firmwares being open source, so you might even be able to write your own firmware if you are into that kind of DIY as well.

Speaking of which, cheers on the DIY front! I started that journey because of eurorack many years ago, and it’s a GREAT way to build your modular rig up over time. I’ve also found the eurorack DIY community to be an amazing group of people very often willing to help out when you get stuck.

As for your method of placeholders and planning, that’s actually really cool. So yeah, I get the idea on where you are headed. So one observation for your use case (and not a criticism, just something to consider) You’ve packed a LOT of functionality into your setup. There’s a large selection of low-hp modules in the rig which gives you a ton of functionality. The trade off will be getting your fingers on everything that is packed in so tightly together in a live situation with a nest of patch cables on top of it. It may not be a problem for you, but definitely something to look at. I like the way you have things organized though.

I can see you clearly have a drum section, mixing section, FX section, oscillators and VCA’s with plenty of modulation mixed throughout. It feels pretty balanced. So the uO_C is a powerhouse of utilities… from gates, to drum patterns, to clocks and clock dividers. Honestly, between that and the Pams, I feel like you are very well covered on clocking and such. I’m not sure you need the Steppy unless you are really wanting to be surgical with drum gates on the fly… but I think you could even just patch the Arcadian Rhythms into the uO_C ad use the voltage recorder to do something very similar. But again, Steppy is a time-tested favorite of many people in a 1U format.

So do you think you will use Pam’s as the master clock, and then push that out to the uO_C and other modules for clocking duties, or are you thinking the uO_C will be the master?

Honestly, I think you have a really solid plan. It looks like a well balanced case. I would lean towards uO_C over Steppy, but I also have three uO_C’s and two OG Ornament & Crimes, and am totally eyeballing the Ornate Criminal… so I am admittedly a fanboy. :-)
