Optimize, actually. I did a rework of this, came up with...
ModularGrid Rack
Audio in the top row, modulation/control in the bottom. By clarifying the signal paths in this way, it becomes much easier to wrap ones' head around what's actually going on. There's really only ONE change I would suggest as far as modules, that being to replace the Zeroscope with an Intellijel Dual VCA ii, then placing this alongside the 3xMIA so that you've got your mixer/distro AND your modulation amplitude controllers all in one place. The Zeroscope is sort of a "luxury", and in smaller builds, it's important to minimize/eliminate things like that so that everything has actual synthesis functionality. Other than that, it's a pretty solid build.
