Add me to the "DON'T" column where these mini cabs are concerned. They exist for very specific types of builds...say, if you want to add a modular modulation setup to an existing synth with the proper I/O. But they 100% SUUUUUUUCK for building a proper modular synth. Since you only have at most about 60 hp to play with, you can either build
1) a really disappointing modular with a lot of the necessary control functions missing, or
2) a really disappointing modular that DOES have all of the necessary control functions, but unless you've got fingers that are the diameter of chopsticks, you're going to have a VERY bad time controlling/adjusting things.
I know that there's a Certain Synth Retailer that does a lot of these minicab builds for YouTube demos. And sure, they tout 'em up real good. But in case you've not noticed, look again...by the time the demo clip is done, after some 10-20 minutes, they've exhausted the possibilities for those builds. And with a well-implemented modular system, that should either NEVER happen, or you'll be old, grey and wrinkly by the time it does.
I would strongly suggest deleting this build, for starters. Instead of trying again immediately, though, get a copy of VCV Rack if you don't have one. Explore that, and you'll eventually start to notice that getting really incredible results hinges on matters of scale and not having one or two specific modules in a "beauty case". Give VCV a real thrashing, get a much better idea of what's needed and WHY, and THEN come back to trying builds here once you're armed with a much clearer vision of what needs to be in them, and therefore, what sort of build size you're REALLY needing. It'll help you avoid some very expensive mistakes! https://vcvrack.com/
