Description
ADSR is a four-stage linear envelope with two expressive ranges. Each stage can be
modified independently allowing for the creation of complex, multi-segment envelopes.
Great for modulating filters, VCAs, and oscillators.
•4 independent stages
•Wide voltage output at 0V –10V
•2 expressive ranges
•Easy to use interface

Installation
To install, locate 2 HP of space in your Eurorack case and confirm the positive 12 volts
and negative 12 volts sides of the power distribution lines. Plug the connector into the
power distribution board of your case, keeping in mind that the red band corresponds
to negative 12 volts. In most systems, the negative 12 volt supply line is at the bottom.
The power cable should be connected to the ADSR with the red band facing the front
of the module.

General Functions Overview
1. GATE:
Gate input
An envelope will emit from OUT when a gate signal is received at the GATE input
Threshold: 2.5V
2. RANGE:
Toggle that will switch between two ranges
If the toggle is up, the slow range will be selected
If the toggle is down, the fast range will be selected
Slow Range: 0.54ms –5 sec per stage
Fast Range: 5ms –30 sec per stage
3. LED:
LED indication of the envelope emitted from OUT
4. OUT:
Envelope output
Range: 0V –10V
5. ATTACK:
Sets the attack time of the envelope
If the knob is far left, the attack time will be as fast as possible based on the currently
selected range
If the knob is far right, the attack time will be as slow as possible based on the
currently selected range

7
6. DECAY:
Sets the decay time of the envelope
If the knob is far left, the decay time will be as fast as possible based on the currently
selected range
If the knob is far right, the decay time will be as slow as possible based on the
currently selected range
7. SUSTAIN:
Sets the sustain level of the envelope
If the knob is far left, the sustain level will be as low as possible
If the knob is far right, the sustain level will as high as possible
8. RELEASE:
Sets the release time of the envelope
If the knob is far left, the release time will be as fast as possible based on the currently
selected range
If the knob is far right, the release time will be as slow as possible based on the
currently selected range
