This project is brand new. I just ordered the PCBs (5/35/12) and will be testing them out in a few weeks.
I will post schematics once the boards have been tested. 
The image below is of 4 analog synth modules.
1. QUAD VCO (wide range VCOs from LFO to audio)
2. VCO/VCA/VCF (single voice module)
3. S&H/DUAL RING MODULATORS/COMPLEX SEQUENCER(FX and modulation module)
4. TOUCH CONTROL,PROGRAMMER (touch controlled voltage and preset bank)
<strong>stacking control boards</strong>
Layout is standardized to allow easy connection with stacking interface and control boards, or jumpers can be run to panel mounted hardware on a custom interface. 
The stacking control board will enable the builder to connect all external hardware simply by plugging the control board on top of the module. 
I will design these once the PCBs have been tested. All pots and switches will be mounted on the board and I intend to use Arduino style headers and bread board jumpers for all modular signal patching which will make this a powerful and very compact system.
