And I'll toss my 2 cents in and suggest some Boolean logic plus small clock modulators, especially if this is a companion to the 2S. Plus, Ronin's advice on the mults is spot-on; in a small build like this, the ONLY mult module that should be in there is a buffered mult, and that only if you've got enough (over three is my usual rule of thumb) destinations for a single CV that must be replicated precisely so that all of the modules controlled by it (and those are usually VCOs or similar) do exactly the same thing. Otherwise, what they are are 6 hp that could be used for any number of other things. As for mults, I'd suggest some stackcables or inline multiple widgets, as neither require ANY panel space.
