Caudal, a highly sought-after module in VCV, has now been adapted to hardware.

​

At its heart, Caudal features a mechanical simulator capable of running various chaotic systems.

​

Caudal offers these operating modes:

• Pendulum: A four-segment pendulum swinging without friction.

• Planets: Four planets experiencing the effects of gravity in a micro-universe.

• Fish Tank: Four fish continuously navigating within their tank.

• Fluctuations: Four chaotic voltage generators reminiscent of the Buchla fluctuating voltage generator.

• Coupled Oscillators: 8 oscillators based on the Kuramoto model, which either lock or interfere with each other.

• Feedback Dynamics: Coupled delay differential equations using nonlinear feedback to produce chaotic signals, based on the Mackey-Glass system.

• Analog Shift Register: 8 analog shift registers that create pseudo-random signals that can be locked, similar to the Turing Machine module.

• Kicked Rotors: Periodically kicked nonlinear rotors, modeled after the Chirikov Standard Map.

​

Caudal produces 8 output signals capable of modulating your system. These signals vary from very slow frequencies to a few hundred hertz.

​

Two input jacks manage two sets of sample and hold blocks linked to each output. In the Analog Shift Register and Kicked Rotors modes, these inputs double as clock inputs for the discrete-time models.

 

The simulation's core allows for controlling storage, recall, and reversing of the simulation.
