If you're set on that 104 hp width, Intellijel's 7U might make more sense. It would allow you to remove the Befaco Out, and the Buffered Mult (although, tbh, you don't need that with this few VCOs...you can use inline passive mults and open up more space), plus add some option possibilities that can give you more control, such as a Quadratt, MIDI interface, etc etc. Just keep in mind that with that case, you MUST use Intellijel-format tiles; the "standard" Pulplogic sizing won't work in their case. And yes, go back to a pair of Erica PICO Mods, since these are extremely useful for quick-n-dirty EG + VCA control over CVs and mod signals. Finally, yeah, I know black looks snazzy and all that, but those Vintage panel Doepfer modules add up. Going with the sleepy-looking aluminum ones makes more fiscal sense. Yes, they break up the color scheme...but given the ones you've got here, you can make use of those aluminum panels to break up the patchpanel into functional "zones" that're easy to see. Oh...and definitely spring for the Batumi's expander, Poti. It's worth it in $$ and the 3 hp it needs.
