UNOFFICIAL FIRMWARENOT FROM ARTURIA · COMMUNITY BUILDS
Community developers are writing their own custom firmware, also called alternative firmware, for the MicroFreak. This is a selection, not every fork or experiment: we list the projects with a working build and a real following, and check them every day. FW Radar doesn’t host these files and doesn’t send alerts for their versions: each link opens the developer’s page.

by ThisFreakDoesntExist
A tool that patches your own copy of the official 5.0.0 update file. It splits Decay and Release onto separate controls saved in presets, puts every mod matrix amount on a MIDI CC, and optionally adds Delay and Duo voice modes.
Needs Python and the official 5.0.0.2084 file; do not share patched files. Matrix CCs may break the Vocoder, voice modes partly untested. The official file restores stock.
READ THIS FIRSTAt your own risk, and it may void your warranty. Read the developer’s install notes, back up your presets, and make sure you know how to go back: official 5.0.0 and how to install it →
Running one of these?Mark it in your rig: the MicroFreak won’t show as out of date, and you still hear about official updates.

An alert the day a new MicroFreak firmware ships, by email, Telegram or push
Your whole rig in one place, with the version each device is on
Used and new Reverb prices for your gear
A public rig page to share, if you want one
We check Arturia's official download page for the Arturia MicroFreak every day. One message per release. No spam, no newsletter.
It’s written by independent developers, not by Arturia. Some projects are stable, others are early betas: read each developer’s notes before you flash.
Can I go back to the official firmware?
Yes: load the official 5.0.0 with MIDI Control Center, as described in the official update guide.
Why isn’t every MicroFreak project listed?
We pick the ones worth trying: a build you can install and a real following, from GitHub stars and downloads or from the community. Forks that only rename a project or add a few presets stay out, and brand-new projects get a second look after their first week.
Does FW Radar track custom firmware versions?
We note the latest version each developer has published when we check the list, every day, but we don’t send alerts for it: alerts are only for official Arturia firmware.
