ADDAC NChunk clone

ladies and gentleman! short of money I decided to start building synth modules on my own. I stumbled over this: http://addacsystem.com/product/addac300-series/addac302-nchunk and would be very happy if someone shows up who has wether- done it likes to do it too, or knows how to do it

btw, I´m a noob. help highly appreciated- thanks!
