Matthias Puech has released a ‘parasite’ for the Mutable Instrument Clouds – an alternative firmware, based on the original open-source firmware – that brings new features to the module. 

Clouds Parasite is an alternative firmware for Clouds. It adds the following main features to the module:

• The Oliverb, a new, full-featured creative reverb mode based on the reverb of the original firmware (itself based on a description of the Lexicon 480L), and inspired in design by the Erbe Verb, with CV control over all parameters. It is largely modeless, probably unrealistic and goes far beyond your traditional reverb;
• Resonestor, a polyphonic resonator processor with built-in support for your beloved Karplus-Strong synthesis. Plucked or fed with your favorite sound, it spits out strange guitar sounds, lush chords, evolving drones, and more.
• More envelopes for your grains: the Texture knob allows to select ramp down or ramp up-shaped grains. Square-shaped grains have steeper edges for extra glitch;
• Tempo syncing with clock multiplier/divisor in looping delay, time-stetcher and reverb mode;
• Support for stereo delay (ping-pong delay) and (crude) open feedback loop; improved sound quality of feedback and delays.
• Availability of much smaller grains compared to the official firmware.
• All features of the official firmware are left untouched and still accessible as before.
