An extra row or longer rows really would be the solution here. One thing I noticed while reworking this was that there was too much "oversizing" going on, which is why some things got changed out to shrink them and open up more space. But 84 hp rows really do put a clamp on what you can do; add one large module to a row, and that row is pretty much locked into what that module does. The Tiptops are a little large, but when you look at the functionality (and price!) they offer, they're worth it. The MISO, for example...basically a CV manipulation toolbox. And the Fold also adds an audio subdivider to things, besides the CVable waveshaping.
But yeah, I get that. I'd much rather try and get this build's functionality into something larger so that a few more useful widgets can be added. More logic comes to mind, plus clock manipulators. But I figured it was best to stick with the OP's original form factor and basics for clarity.
