The remaining 20hp would be good for: Tetrapad, Qubit Synapse, or Instruo's upcoming ER-301 related faders/gates module.
Though that Instruo is 22hp so I would probably need to ditch both Chance and Ornament and Crime and then fill in the remaining 6hp with what, Intellijel Shifty?

Alternately, could get the Harmonaig Quantizer and Wogglebug, ditch O&C and Chance.

Links/Lxd/MA Mix are all good 4hp options to pair with E352 if I ditched ER-301.


Nah...go with a smaller O&C build, something like: https://www.modulargrid.net/e/other-unknown-uo-c-magpie-white-panel which fits in 8 hp. Then maybe chuck the Blinds, since the Samara does what it does plus bunches more. Plus, consider whether the ER-301 can do any of the effects processes you have on here as separate modules in-line with the function you've got in mind for it. Keep looking at how to 'squish out' the hp needed while not losing much in the way of function...it's doable, just part of the scutwork in optimizing a build. Treat it like a challenge!
