Anyone got the Rectangular thing guys? I have a DIY unit and can't figure out how modulation works.
None of the MOD knobs do anything and nothing happens with external modulation through the dedicated MOD input.

I'd contact Stijn above - you should be bale to private message him - however it seems like you probably have some defects in your build - so posting hi-res photos of the board to somewhere that's more oriented towards DIY might be a good idea - Modwiggler's Music Tech DIY subforum would be my choice!

good luck!

Thank you very much my friend. A friend of mine is taking care of it!
