Vult Caudal

Mechanical Chaos Source

10 HP Eurorack module

Caudal is a hardware mechanical-chaos source with eight chaotic-system simulations and eight modulation outputs.

Features

• Eight distinct outputs for modulation.
• Two sample-and-hold banks capture and hold all output values.
• Speed and Energy each have CV control with an attenuverter.

Controls & Jacks (26)

• A Y Output— Y output for chaotic signal A.
• Speed— Sets the time scale of the chaotic simulation, from very slow movement to a few hundred hertz.
• Energy Attenuverter— Bipolar level control for CV applied to Energy.
• B Y Output— Y output for chaotic signal B.
• Energy— Sets the activity or level of chaos; its exact effect depends on the selected model.
• Speed Attenuverter— Bipolar level control for CV applied to Speed.
• Speed CV Input— CV input for the Speed control.
• HIT Trigger Input— Manual/external trigger input for selecting a new random simulation state.
• A X Output— X output for chaotic signal A.
• D Y Output— Y output for chaotic signal D.
• B X Output— X output for chaotic signal B.
• Sample & Hold X Input— Trigger input for the X sample-and-hold bank; each trigger captures all X output values.
• STORE Trigger Input— External trigger input for storing the current simulation state.
• Energy CV Input— CV input for the Energy control.
• C X Output— X output for chaotic signal C.
• RECALL Trigger Input— External trigger input for recalling the stored simulation state.
• REV Trigger Input— Manual/external trigger input for reversing the simulation direction.
• Mode Selector— Cycles through the eight chaotic-system operating modes: Pendulum, Planets, Fish Tank, Fluctuations, Coupled Oscillators, Feedback Dynamics,
• C Y Output— Y output for chaotic signal C.
• REV— Reverses the direction of the simulation elements, making signals retrace their paths before diverging.
• D X Output— X output for chaotic signal D.
• Sample & Hold Y Input— Trigger input for the Y sample-and-hold bank; each trigger captures all Y output values.
• Mode Indicator— Shows the selected operating mode through its LED combination.
• STORE— Stores a snapshot of the current internal simulation state.
• HIT— Selects a new random initial state, immediately changing all outputs.
• RECALL— Recalls the saved simulation state and resumes evolution from it.
