Description:

 

This module is a multi-featured, autonomous, third-order chaos-generating circuit.

 

Its features include (1) a third order response (ie, three outputs) with a total of four nonlinear elements in the circuit path, (2) switch selectable nonlinear elements, (3) voltage control of rate, loop damping, gain and offset, and (4) a reset/inhibit input which allows the system to be set to zero voltage at all three integration stages.

 

Controls:

The controls on a chaos generator are different from those on other synth modules. The best way to learn their functions is to experiment with them. Here are brief descriptions of the functions.

 

RATE:

This is the speed at which the signal traces out its patterns. It is similar to the frequency control of a VCO or VCF. It has an initial setting (to the right) and a standard modulation input (input jack and depth control, to the left). Rates range from slow, creeping LFO-like sweeps, well up into audio frequencies.

 

DAMPING:

Damping is a linear negative feedback around one stage within the circuit. Too little damping will cause the signals to run away to the rails. Large amounts of damping can cause the signal to die out altogether. Damping is similar to resonance in a VCF, with less damping analagous to more resonance. As with the rate control, there is a control for the initial amount along with a standard CV input.

 

OFFSET:

It turns out that a DC offset voltage within the main circuit loop is an important parameter in this circuits. Its main effect is to change the overall signal amplitudes, ie the size of the chaotic attractor. Again, this parameter is under voltage control in Chaotica.

 

GAIN:

This is the overall (global) gain in the main circuit loop. It's just a little internal VCA! The amount of gain affects the overall size of the attractor, as well as the the amount of damping. The damping and gain controls work together in determining the chaotic pattern generated. Also voltage controllable.

 

NL DRIVE:

Nonlinear drive amount. Chaotic behavior in an electronic circuit comes from internal feedback loops containing nonlinear circuit elements. The NL Drive control varies the amount of feedback of one of these loops. This is one of the controls determining the strength of the chaotic pattern.
