THINGS TO KNOW
What is 1U? 1U is a measurement of height in the 19” rackmount stan-
dard. Eurorack modules adhere to 3 rack units, or 3U. Mo-
saic tiles adhere to 1 rack unit in height, and require appro-
priate rails to mount in a rack or modular case.
What 1U
format are
Mosaic
modules?
We ship our modules with Intellijel 1U formatted front pan-
els. If you use the Pulp Logic format, don’t worry! You can
purchase Pulp Logic replacement front panels on our Re-
placement Panels page.

OVERVIEW
Description
Shape sound sources and modulate parameters with the dedicated ADSR envelope. This four stage
envelope gives individual control over each stage, allowing for complex, yet detailed modulation
over filters, VCAs, effects, and more. Patch in punchy synth stabs, sweeping pads, and powerful
sonic transformations with the ADSR.
• Four stage envelope
• 10V range for maximum control potential
• Ergonomic layout
Tech Specs
• Width: 14HP
• Depth: 38mm
• Front Panel: Ships in Intellijel format. Pulp Logic replacement panels available here.
• Current Consumption: +12V = 24mA, -12V = 7mA
Installation
To install, locate space in your Eurorack case for your 1U module, and confirm the positive 12 volts
and negative 12 volts sides of the power distribution lines. Plug the connector into the power distri-
bution 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 connect-
ed to the module with the red band facing the front of the module.

DETAILS
How It Works
An envelope generator, such as ADSR Envelope, is a form of triggerable modulation with con- trol over the level over the triggered voltage cycle. In this case, ADSR gives you control over
Attack, Decay, Sustain, and Release which are elaborated on below. The envelope begins when
it receives a high gate or trigger signal, and ends when the gate goes low and the release stage is
complete.
Depending on how you shape your envelope, you can create brief moments of modulation, or
long sweeping changes. Envelopes are commonly used to modulate signal amplitude and filter
frequency, but can be sent to anything that receives control voltage (CV). Send it out everywhere,
and find where ADSR fits best for you!
Note: Common in modular synthesizers, the attack, decay, and sustain stages are only active
when the gate is high. Once the gate is low, the envelope will advance to the release stage.

DETAILS
1. Gate Trigger
Gate Input. An envelope will trigger when either; the Gate input receives a gate signal or; the Gate
button is pressed.
Threshold: 2.5V
2. Attack
Controls the attack stage of the envelope. Attack will be as short as possible when the knob is fully
left, and slowest when the knob is fully right.
3. Decay
Controls the decay time of the envelope. Decay will be as short as possible when the knob is fully
left, and slowest when the knob is fully right.
4. Sustain
Controls the sustain level of the envelope. Sustain is at 0V when the knob is fully left, and 10V when
the knob is fully right.
5. Release
Controls the release time of the envelope. There is immediate release when the knob is fully left, and
longest when the knob is fully right.

6. Slow/Fast Envelope Mode
Toggles between the slow and fast envelope ranges.
Fast Range: 0.54ms - 5s per stage
Slow Range: 5ms - 30s per stage
7. Envelope LED
VIsual indicator for the envelope amplitude.
8. Output
Envelope Output. Range: 0V - 10V
