EG 2hp Envelope Generator — Cheat Sheet

Overview

Type: 2-stage envelope generator (Attack/Decay)
Envelope shapes: Switchable linear/exponential
CV control: Attack/Decay
Output: 0–10V envelope
Built-in attenuator (AMP)
Super compact (2hp), 3ms–11min per stage

Panel Control Reference

Function	Type	Description	Voltage Range
TRIG	Input jack	Trigger or gate to fire envelope	Threshold: 2.5V
ATTACK CV	Input jack	CV input for Attack time	0V – 5V
ATTACK	Knob	Manual control for Attack time (min left, max right)
DECAY CV	Input jack	CV input for Decay time	0V – 5V
DECAY	Knob	Manual control for Decay time (min left, max right)
RESPONSE TOGGLE	Switch (2-way)	Select envelope shape: Up = Linear, Down = Exponential
AMP	Knob	Output envelope level; attenuates from 0V (left) to 10V (right)	Output: 0V – 10V
ENVELOPE LED	LED	Visualizes output envelope
OUT	Output jack	Final envelope output (attack & decay controlled by above)	0V – 10V

Basic Operation

Patch TRIG input to receive gates/triggers (>2.5V) from sequencer, keyboard, clock, etc.
Set ATTACK and DECAY with knobs—their full range is 3ms to 11 minutes (per stage!).
Add CV to ATTACK/DECAY CV inputs for voltage control (0V–5V typical).
Toggle RESPONSE for desired shape:
Up = Linear
Down = Exponential
Set AMP for attenuation (0V to 10V envelope output).
Patch OUT to next destination, like VCA, filter, or other modulation destination.
