2-Op Chaos


The 2-Op Chaos module contains a number of chaotic equations where behavior is determined by two Chaos controls. It contains the following maps:

  • Cusp
  • Gauss
  • Henon
  • Hetrick (the result of a bug from implementing Henon incorrectly on the first try)
  • Mouse

Shared controls between the Chaos modules:

  • Sample Rate: Since these chaotic maps are non-periodic (except at certain values where stable behavior occurs, especially in the Logistic map), there isn't a Frequency control. Instead, the rate of sample generation is governed by this control.
  • Fast/Slow: This switch determines the range of the Sample Rate control. Slow mode is 100x slower than Fast mode. In Fast mode, 100% Sample Rate matches Voltage Modular's 48 kHz sampling rate.
  • Slewed/Stepped: In stepped mode, the samples are generated normally. In slewed mode, each sample is smoothly, linearly slewed. For CV, this creates smooth modulation signals, while for audio, this applies a nice low-pass filtering effect.
  • AC/DC: In DC mode, the outputs are not filtered. In AC mode, a high-pass filter is applied to the outputs to remove DC offset. If you are using these modules to generate audio signals, you should use AC mode. If you are generating modulation, you should use DC mode.
  • Clock: If a gate signal is present here, new samples will only be generated on the reception of a new gate (or whenever a signal crosses the 1V threshold).
  • Reseed: Generates new initial values for each chaotic map. For some maps (Gingerbread especially), this can have a massive effect. For other maps (Quadratic, Tinkerbell, and others), this can be useful for restarting the map if it dies off.
