UNOFFICIAL FIRMWARENOT FROM NOVATION · COMMUNITY BUILDS
Community developers are writing their own custom firmware, also called alternative firmware, for the Circuit. 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.

Circuit Extended
by tracelistener
A patched version of the Circuit's 1.8 firmware: drum pitch follows the scale, and Shift plus the macros adds sample start, distortion type and a filter LFO, all recordable. The latest build also answers MIDI pitch bend, mod wheel and aftertouch. Installed from a browser uploader in Chrome or Edge.
Only for firmware 1.8 build 3592. Back up your pack in Components first. The default build is experimental, some only tested in emulation. Components restores the official firmware.
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 1.8 and how to install it →
Running one of these?Mark it in your rig: the Circuit won’t show as out of date, and you still hear about official updates.
An alert the day a new Circuit 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
The Novation Circuit is no longer made, but Novation can still ship firmware for it and we keep checking the official download page. One message per release. No spam, no newsletter.
It’s written by independent developers, not by Novation. 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 1.8 with Novation Components, as described in the official update guide.
Why isn’t every Circuit 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 Novation firmware.
