Ok I notice we're doing big boards now, and this would definitly be big. I'm 100% confident it can be done, madbean has a (discontinued) pcb for it (they only offer a heavily modded 2015 version now) and there are other project pages for it, I will link them all. It would be a terrific addition to the site because it's an analog octaver that can do -2 -1 and + 1 octave and I don't think there's anything of the like on the analog market. I think the old "Lowrider" would probably be the clearest and best to follow since it's a 1 on 1 copy of the original with modern parts.
