Quadigy

 

Quad Envelope Generator

 

7-stage envelopes, presets, cycling, morphing & CV matrix 

Introduction 

The Quadigy is a complex envelope generator focused on live play. The goal is to allow the user 
setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a 
subtle and intricate patch once on stage. This is achieved by offering two main modes, one where 
full control is available, and a Live mode where only the settings that are sensible using on stage 
are accessible. The user interface offers an intuitive access for otherwise complex settings. 
Advanced features such as automatic time-stretching, multiphase clocking and full morphing 
between presets put the Quadigy in a category on its own.
