The Voltage Modular Miniverse Poly Contour is an ADS envelope generator used to dynamically shape note volume, filter cutoff, or any other voltage-controlled mod destination. It's functionally identical to the standard mono version, but has up to 16-voice polyphony via its poly jacks.

If you're not familiar with the operation of ADS envelope generators, here's an overview:

When the module receives a gate voltage, the contour generator outputs a dynamically changing voltage, according to the settings of its stages. The Attack Time stage defines how long it takes for the output voltage to rise from 0 to 5 volts.

Once the attack stage reaches 5V, it moves to the decay phase, which defines how long it takes to fall from 5V to the setting of the sustain phase.

Unlike Attack and Decay, the Sustain phase is not a time-based control - the Sustain knob sets a voltage level that's held until the gate voltage is removed.

Inputs, Outputs, and Controls

Attack Time- Defines the length of time for voltage to rise from 0V to 5V when a key is played.

Decay Time- Defines the length of time for voltage to fall from the attack stage 5V peak to sustain stage setting. The Decay knob behaves differently depending on the position of the Decay switch explained below

Decay switch. If the Decay switch is off, notes will immediately stop sounding when keys are released. If the Decay switch is on, the Decay knob also defines how long it takes for notes to fade away when a key is released (much like the Release control in a standard ADSR envelope generator.

Sustain Level- Sets the voltage level (i.e. held note level) following attack and decay phases while a note is held.

Gate Signal- This is where you'll patch gate voltages to initiate the envelope generator cycle. Typically this would come from the Poly Gate jack in the IO Panel Poly Sources section, or from any other poly source in Voltage Modular.

Contour Output- Envelope output voltages.
