Overview

A traditional ADSR envelope with modulate-able controls for the 4 stages: attack time, decay time, sustain level and release time.

Parameters

input

Comparator

This parameter gives you access to the threshold level of the input comparator used to detect the rising and falling edges of your incoming gate signal. There is also a button for manually firing gates.

attack

Gain/Bias

This parameter sets the (maximum) amount of time it takes for the envelope to ramp up to a value of 1 when it receives a gate signal. The attack portion of the envelope is triggered by a rising edge at the unit input.

decay

Gain/Bias

This parameter sets the (maximum) amount of time it takes for the envelope to decay from 1 to the sustain level.

sustain

Gain/Bias

This parameter sets the amplitude of the sustain portion of the envelope. The decay stage ends at this level and the release stage begins at this level.

release

Gain/Bias

This parameter sets the time it takes for the envelope to fall back to zero. The release portion of the envelope is triggered by a falling edge detected at the unit input.
