A few notes here...
First of all, with this much sequencing and clocking, this build SCREAMS for a serious Boolean logic module to take the clock manipulation to the next level. If you can mash it in (that black blank panel in the 3 x 84 cab looks possible, might need a little shuffling), I'd suggest the ARC Artificial Neural Network. Does Boolean, some Neural Net tricks, plus you get a comparator, a couple of Schmitt triggers (sort of like decay-only EGs) and a lot of unconventional tricks.
Next, the B. Highpass VCF at the bottom...I'd consider something else, actually...since that's intended to emulate the 904 Moog VCF set HPF, which would have it working in tandem with the 904A, via a module that's curiously absent: the 904C filter coupler. How Uli gets a pass for saying he can emulate a System 55 without that key device is...well, it's ULI is what it is. He probably has no clue as to what a 904C IS. Fortunately, Dieter Doepfer's got yer fix...which actually is BETTER than the 904B...in the A-123-2. More cutoff slopes, more control, all that.
However, there's another problem sitting right next to the 904B...the power supply module. As a rule, you never want a power component adjacent to an audio module. The audio path is too easy to contaminate with P/S hash and garbage, plus whatever line frequency hum that manages to leak past the DC converter and into the uZeus. Now, you can fix the AC ripple with a ferrite on the power input cable (you'd put it right where it LEAVES the DC converter, not by the uZeus input itself), but not the switching supply hash...which CAN sneak in as ultrasonics and those can screw around with the audio result. Easy solution, though...just move it to the OTHER END of that row, as the crud leaked by cheap switchers won't affect anything in the White Gallop.
Other than that, the only other issue I see here is ergonomic: you should probably make the build's layout more coherent by doing some specific functional grouping...VCOs go here, VCFs there, etc. It'll make this loads easier to navigate; right now, it's a real hodgepodge, and that's never useful nor intuitive to use. Otherwise, it's got the goods!
