Cosmotronic Peradam Eurorack Sidechain Distortion Module
Eurorack sidechain compression module
Peradam is a distortion module with an internal sidechain, it's a compressors twisted brother. The input signal is split up, with one half going into a VCA, and the other half going into a sidechain rollercoaster.
First its phase is modulated, before a full ring modulation, creating a signal at twice the frequency. This signal then modulates the amplitude of the original, creating complex self distortions.
That output goes into a dual band drive circuit, similar to the one found in Cosmix. before entering the soft clipper output stage. Things get really wild when you start feedbacking this output back into the input.
The module even goes into self oscillation at high feedback levels, producing all sorts of crazy sounds. Modulating all these parameters gives a broad palette of distortions, from subtle saturation to complete destruction.
The signal path is very clean, because the distortion is achieved with a sidechain, instead of just driving up the gain. A blend control allows you to further dial in your tones.
