Pura Ruina

The Pura Ruina is the last in the Distortion of the Month series from Noise Engineering. The PR is a three-stage full-wave rectifier and distortion module. PR features four individual stage level controls, each with CV input and individual output. The Universal Sum output is sum these stages.

Pura Ruina's fully-hyphenated full-wave rectification adds a different flavor of distortion than standard wavefolding or clipping. Rectification is a process where the negative portion of a waveform is folded over upon itself to create a positive-only waveform. This complex and gnarly form of wave shaping adds character and richness to any signal fed into it and is perfect for complementing any system it resides in.

Pura Ruina Demo - Three-stage CV controlled full-wave rectifier and VCA
Pura Ruina is a three-stage CV-controlled fully-hyphenated full-wave rectifier/distortion designed for audio. Simple waveforms can be manipulated into completely new and exciting tones, and already-complex sounds can be shredded into sonic oblivion. Add some CV and you’ll never want to let PR out of your rack!

Each stage has an individual level control with corresponding CV and individual out, as well as feeding to the universal Sum output. PR’s rectification creates a unique flavor of distortion unlike standard wavefolding or clipping.

The possibilities are virtually endless: add to a west-coast style complex oscillator setup for unique timbral shaping, annihilate a percussion mix through it, run its individual outs through other Ruina modules for further mayhem...
