ModularGrid Rack

My current version has another filter instead of Pam's and an Erica dual ASR that I want to replace with the Intelligel ADSR because I prefer the layout and functionality for the HP ... but for all intents and purposes, close enough to where I'm at.

This is sitting in a Nifty Case giving me my power and some I/O options. Additionally, this sits just above a Moog Grandmother. Technically this is its companion and expander. The intent is to create more complex textures to complement the moog and also create more esoteric sounds, courtesy of Beads.

As you can see, I got 2 HP spare. I'm still pretty damn fresh to this, but I feel this is a respectable and useful setup ... but with 2 HP left, what would you slot in there?
