Make Noise Contour 1

MiniMoog-inspired 4-stage envelope with variable response

8 HP Eurorack module

CONTOUR is a 4-stage function generator derived from Make Noise's 0-COAST synthesizer, inspired by the original MiniMoog Loudness Contour circuit. It creates control voltages with a simplified 3-knob interface (Attack/Decay/Sustain) plus variable response shaping, designed to drive fast VCAs and filters for classic East Coast synthesis envelopes.

Features

  • 4-stage ADSR envelope generator
  • Mirrored output for crossfading
  • Variable response from linear to exponential
  • EON/EOC gate outputs
  • Sustain overdrive up to 10V
  • Self-cycling LFO capability
  • Voltage control over Attack and Decay

Controls & Jacks (14)

  • Vari-Response— Sets the response curve of the Contour function. Response is continuously variable from Linear to Exponential.
  • Sustain— Sets the voltage level the function decays to and holds for the duration the Gate is High. Settings greater than 3:00 enable overdrive mode.
  • Decay— Sets the time it takes for the voltage function to ramp down to the Sustain stage and complete the Release stage. CW rotation increases Deca
  • Onset— Sets the time it takes for the voltage function to ramp up to maximum level. CW rotation increases Onset Time.
  • EON Out— Outputs a trigger pulse at the end of the Onset stage.
  • Contour Output— Outputs the envelope control voltage (0V to 8V, or up to 10V in Sustain overdrive mode).
  • EOC Out— Outputs a trigger pulse at the end of the complete Contour function.
  • EON— Indicates the end of the Onset stage.
  • Gate Input— Gate input that initiates the envelope. Range 1.5V or greater, with Gate Width determining Sustain Time.
  • Enter— Alternative gate input for entering the function sequence.
  • Onset CV Input— Linear control signal input for the Onset parameter. Positive signals increase Onset Time, negative signals decrease it.
  • Decay CV Input— Linear control signal input for Decay parameter. Positive signals increase Decay and Release Times, negative signals decrease them.
  • EOC— Indicates the end of the Contour function.
  • Enter LED— Indicates gate/trigger entry state.
