About Kosmo

This giant wall of synth is Kosmo. Kosmo is a modular synthesizer built over the last year. It is primarily composed of modules designed by other folks and put together by me. It was heavily inspired by Look Mum No Computer.

Kosmo is a format named by Sam (Look Mum No Computer). The modules are essentially scaled up Eurorack modules. This makes building them simpler (no surface mount soldering) and it makes playing them extra fun.

Sam and a few others from the forums have made PCBs and front panels available to purchase.

One day I got jealous of all those synths with built-in speakers so I figured I would make my own. I took one of those small belt Marshall amps that I found busted at a garage sale, combined it with speakers harvested from a failed circuit bend, and made this monstrousity to be the base of my Kosmo modular.
