Editor & simulator

Patch it in your browser.

The free editor patches modules, turns knobs live and shows every CV on a built-in scope. No hardware yet? The simulator runs the exact same firmware core on your laptop — a complete synth, in a browser tab.

Try it before it exists.

The editor is the same tool you'll use with the hardware — so you can design patches, learn the routing and hear the simulation today, and load them onto a Cortex the day it arrives. It talks only relays, CV and gate; your ideas stay yours.
