The Tomkat Cloudy is a digital guitar pedal adaptation of the Eurorack module "Clouds" by Mutable Instruments, the granular texture module widely used in modular synthesizer systems, rebuilt as a stompbox for guitar players1. It runs the "Parasites" alternative firmware, a community firmware for the Clouds platform that extends what the original module can do1.
What it does
Cloudy carries six different digital programs: granular synthesis, pitch shifting, delay, reverb, filters, and resonators1. RockBoard's PedalPedia lists its effect types as pitch shifter, delay, reverb, filter and modulation1, so it sits in the same territory as a multi-effects pedal while keeping the granular character of the module it is based on. Players who know the individual modes will find overlap with dedicated delay pedals, reverb pedals, octave and pitch pedals and filter pedals, but the Cloudy's draw is the granular synthesis program, which treats the incoming signal as small overlapping grains of sound that can be frozen, shifted and layered.
Power and practical notes
The Cloudy runs on 9V DC, center negative, and draws 200mA1. That current draw is well above what many compact power supplies provide on a single output, so it needs a supply output rated to deliver at least 200mA.
At 200mA, the Cloudy will overload a low-current daisy-chain output. Give it a dedicated high-current output on the power supply.

Questions
What is the Tomkat Cloudy based on?
The Cloudy is a guitar pedal adaptation of the Clouds Eurorack module by Mutable Instruments. It runs the Parasites alternative firmware for that module, which extends the original design with additional modes. As a pedal, it puts a module usually associated with modular synthesizer systems into a format guitar and bass players can use on a pedalboard.
What effects does the Tomkat Cloudy cover?
It carries six different digital programs: granular synthesis, pitch shifting, delay, reverb, filters and resonators. Tomkat lists its effect types as pitch shifter, delay, reverb, filter and modulation, so it functions as a multi-mode texture pedal rather than a single-effect unit.
How much power does the Tomkat Cloudy need?
It runs on 9V DC, center negative, and draws 200mA. That is more than many standard pedal power supplies deliver per output, so it needs a supply output rated for at least that current rather than a low-current daisy-chain tap.
