Vult Feigen

Quasi-chaotic voltage source

10 HP Eurorack module

Feigen is a quasi-chaotic voltage source based on the Logistic Map equation, producing periodic or chaotic patterns for modulation and musical sequence generation.

Features

  • Growth, Range, and Offset each have a dedicated CV input and attenuverter.
  • Root selection and reset control the generated sequence's initial state.

Controls & Jacks (14)

  • Offset CV Input— CV input for the Offset parameter, scaled and inverted by the Offset Attenuverter.
  • Range Attenuverter— Sets the amount and polarity of CV applied to Range.
  • Growth— Sets the Logistic Map growth characteristic, progressing from two-value oscillation through bifurcations and periodic patterns toward chaoti
  • Clk— Receives the clock that advances the generated sequence.
  • Offset— Adds a constant voltage to the output, from -5 V to +5 V.
  • Range— Sets the output amplitude from 0x to 2x.
  • Out— Main generated voltage output; its offset and amplitude are set by the Offset and Range controls.
  • Growth CV Input— CV input for the Growth parameter, scaled and inverted by the Growth Attenuverter.
  • Reset— Resets the internal state to the value defined by the Root control and Root CV input.
  • Growth Attenuverter— Sets the amount and polarity of CV applied to Growth.
  • Root CV Input— CV input that contributes to the Root value used to establish the sequence state on reset.
  • Offset Attenuverter— Sets the amount and polarity of CV applied to Offset.
  • Root— Sets the initial sequence state recalled when the module receives a reset.
  • Range CV Input— CV input for the Range parameter, scaled and inverted by the Range Attenuverter.
