Kinda...the problem I have with some of the Moon stuff is that, fully-implemented, it's space-hungry. I went instead with the Dotcom Mix++ modules, both to mix/invert/distro VCO audio signals as well as to do the same with modulation sources. They do a lot of the heavy lifting there, but don't require extra routing, etc expanders. Although, I do like their Quad Reversable Attenuator module. It's turned up in some other build sketches I've done in MU as a convenient and cost-effective attenuverter bank, as has the 592...but the 592 tends to get 'evaluated out' because of the space vs cost issue, while the QRA always seems to make it thru to the final refinements.
On the other hand, the more I see of the Grove Audio modules, the more jazzed I get about their features in small spaces aspect. You'll notice quite a bit of their devices in the above layout, and their appearances have actually been something of a growing trend as I slog toward an eventual budget-commit final version. Their 1-space Quad VCA/mixer is frickin' brilliant, IMHO, and that new Quad VCA stereo mixer is turning into a 'given' in some further refinements of the above.
Ultimately, while a portable cab version is the 'optimal', the real fact is that I'll likely go with something like this:
...if only for cost-savings. It cuts down the module compliment to something a little more fiscally-rational, and the Studio cabs do bring the price down incrementally. Still comes out to roughly $22.5k, which is...spendy, but I like the functionality vs space issues this refined version gives. FYI, the bottom 'row' actually denotes two Box4 enclosures that attach to either end of a QKB37, and these get filled with eight (yep, eight!) wheels to give me some expression CVs that can be sent back upward to other destinations in the synth. Costs a bit more, but that's a functionality tradeoff I like.
