MISO = awesome and inexpensive CV wrangling module. Another possibility there is 4ms's SISM, which is a similar sort of thing with more CV over function. These sorts of modules are pretty indispensable if you're trying to generate complex modulation curves from a few different sources.

One thing I'd suggest about the 2 hp gap in the bottom (sequencing) cab: drop in one of 2hp's Logic modules. This way, you can use TWO Pam's outs that "conflict" with each other in how they're programmed to create even more complex and elaborate clock behavior.
