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.
