This is a fairly simple, dual, voltage controlled ADSR. It is considered to be voltage controlled, because all paramters (Attack, Decay, Sustain, Release and Shape) are all controlled by voltages.
Atack: Voltage controlled. Three inputs.
Decay: Voltage controlled. Three inputs.
Sustain: Voltage controlled. Three inputs.
Release: Voltage controlled. Three inputs.
Shape: Voltage controlled. Two inputs. This controls the shape of the decay. It varies between your typical RC timeconstant type decay (exponential) to linear ramps.
Trig: Edge sensitive. One input. The trigger input starts the Attack cycle. Envelopes can be re-triggered.
Gate:Controlls the Decay/sustain cycle. Level sensitive.
Output: 3 outputs, each with it's own current limit resistor.
Status LED's: There are three status leds. One to indicate the Attack cycle, one for the Decay cycle, and one for the Release cycle.
