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

Clouds Parasite
by Matthias Puech (mqtthiqs)
Reworks the granular mode (reverse, smaller grains, asymmetric envelopes) and the looping delay (clock sync, ping-pong), and adds a full reverb with shimmer and a dual Karplus-Strong resonator.
Recalibrate after installing. The author reports that about 1% of audio updates brick the module (repair needs an FTDI or JTAG adapter). Modules bought from July 2015 need v1.3 or later.
Keeps the stock Clouds modes and adds a clock-synced slicing and beat-repeat mode, with per-slice loop, pitch and distortion, plus Spectral Clouds, a multiband filter with randomly moving bands.
The author notes a small risk of bricking the module. Beat-Repeat needs a clock on the Trigger input.
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 1.31 and how to install it →
Running one of these?Mark it in your rig: the Clouds won’t show as out of date, and you still hear about official updates.
An alert the day a new Clouds 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 Mutable Instruments Clouds is no longer made, but Mutable Instruments 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 Mutable Instruments. Some projects are stable, others are early betas: read each developer’s notes before you flash.
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 Mutable Instruments firmware.
