Had a little fun with this...
Added a dual VCO with interesting crossmod quirks, and two Takaab Nearness fixed-pan, fixed-level mixers. The Antumbra Dual VCA is an improvement over the Doepfer as it offers the same variable-response capabilities as the Veils VCAs. Also, I added an LPG for the Sine/Kickall combo so that you get a more drum-like result that should hit a lot harder.
The Nearness outputs should go directly to the Happy Nerding 3x Stereo Mixer, and you still have a third input (mono or stereo...the HN channels are normalized as "L = mono"). Then this now feeds the FX Aid more appropriately, since you're sending that stereo FX module from a stereo-out mixer. Lastly, I reordered it somewhat to make the signal paths and subsections more apparent for ease of use.
Also...this really would work a lot better with larger modules for ergonomics, which would necessitate a larger case. Something along the lines of a Mantis would be cost-effective AND fill that purpose.
