Overview
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… You’ll never run out of awesome
things to try, we promise. You know you want one.
