There's a lot wrong, actually. For starters, there are exactly zero modulation sources, unless you count the Metropolis, which I don't. No LFOs, envelopes, function gens of any sort spell total disaster for getting any sort of intricate modulation structures across time. Also, no VCAs is another very bad move...you 100% need those for controlling audio or CV levels via...yep...your modulation sources.
As for generating things, you won't be generating much of anything with this build, unless you're opting for driving filters into self-resonance or just using it as a bank of processors (which, without the above two module types, you're still quite screwed). There are no VCOs here. None. And given that pretty much ANY synthesis audio path runs VCO->VCF->VCA, you seem to have a rather serious problem here.
Stop. Delete this atrocity. And before starting over, study some reference material of which there's a good bit lurking in the forums here on MG, other places such as Muff Wiggler, Synthtopia, Vintage Synth Explorer (which is also an excellent reference source for classic designs which are still important to electronic instrument design to this day and which I strongly recommend anyone starting into modular study in depth), and have a look at the excellent documentary "I Dream of Wires", among many other study needs. Otherwise, what you're proposing with this build could be more easily accomplished by piling several thousand dollars in your backyard grill, dousing it with gas, and setting it all on fire.
