How Does It Work?#

Envelope is a classic ADSR generator with end-of-rise and end-of-cycle triggers, plus selectable soft or hard retrigger behavior.

Quick Overview#

• The module responds to a Gate input and generates one unipolar envelope.
• ENV outputs the main ADSR shape.
• EOR pulses when attack finishes.
• EOC pulses when release reaches zero.
• The panel also includes a manual TRIG button and a retrigger mode switch.

Inputs And Outputs#

Port	Type	What It Does
Gate	Gate input	Starts attack when it goes high and starts release when it goes low.
Env	CV output	Main envelope output in the standard 0V..+5V range.
EOR	Trigger output	Fires a short pulse at the end of the attack stage.
EOC	Trigger output	Fires a short pulse when the envelope fully returns to zero.

Controls Reference#

Control	Range	Default	Behavior
A	0.00002..10 s	0.01 s	Attack time.
D	0.00002..10 s	0.1 s	Decay time.
S	0..1	0.7	Sustain level as a normalized fraction of full scale.
R	0.00002..10 s	0.3 s	Release time.
Retrig	Soft, Hard	Soft	Chooses whether a new gate restarts from the current level or resets to zero first.
TRIG	Momentary	—	Manual gate button for auditioning the envelope from the panel.

Behavior Notes#

• Soft retrigger keeps the current envelope level and rises from there.
• Hard retrigger forces the envelope back to 0 before starting attack.
• ENV is scaled to 0V..+5V.
• EOR and EOC are short unipolar trigger pulses of about 1 ms.
• With no gate patched, the envelope stays idle unless you use the panel TRIG button.
