Freakier Firmware Lab

Free, in your browser

Tools

Tools for your instruments. They run on your own computer, in the browser, and nothing you give them is uploaded.

MicroFreak

Patch Generator

Live

Roll new MicroFreak sounds that use every knob and every mod-matrix route, Original or SuperFreaker. Hear them on the 3D model, play them from a MIDI keyboard, and send them straight into your synth's preset slots over USB.

Writing to the synth needs Chrome or Edge on a desktop. Back up a slot first; the tool does it for you.
