CIRRUS is a real-time granular processor for audio signals. This module is an adaption of Mutable Instruments' Clouds module, a well known module in the Eurorack world.

This module uses the extended firmware of the Eurorack Supercell module; meaning it offers four additional algorithms on top of the four original ones.

Unfortunately the chip for this module is no longer available, so this module had to be discontinued.
