The Sapphire plugin offers the following collection of modules that allow you to generate a wide variety of smooth control voltages. Chaotic signals are somewhere between periodic and random.
The modules Frolic, Glee, and Lark each implement a specific chaotic attractor. See their respective documentation pages for details.
Zoo is a user-programmable chaotic oscillator. It comes with presets that give you many more chaotic oscillators.
If you are comfortable with algebra and vectors, you can enter in your own chaotic oscillator formulas and create an unlimited variety of shapes and patterns.
All of the Sapphire chaos modules allow using Chaops on the left and Tricorder on the right. See their documentation pages for more details.
There are also buttons for adding expanders in many Sapphire modules.
