Desmodus Versio is Noise Engineering’s long anticipated take on a reverb. This is a true stereo in/stereo out or mono in/stereo out effect. Less of a room simulator and more of a synthetic tail generator with features designed for sound design and performance, the parameters on DV allow you to take the effect from a delay to a beautiful reverb to an uncanny, nightmarish atmosphere in the twist of a few knobs. Not only is DV a unique reverb, it’s a stereo DSP platform. A simple USB connection allows you to update DV to a variety of firmwares. Open-source support is available, too, which allows you to write your own firmware! All info can be found on the World of Versio page here.
Power
To power your Noise Engineering module,
turn off your case. Plug one end of your ribbon cable into your power board so
that the red stripe on the ribbon cable is aligned to the side that says -12v
and each pin on the power header is plugged into the connector on the ribbon.
Make sure no pins are overhanging the connector! If they are, unplug it and
realign.
Line up the red stripe on the ribbon cable so that it matches the white stripe
and/or -12v indication on the board and plug in the connector.
Screw your module into your case BEFORE powering on the module. You risk
bumping the module’s PCB against something metallic and damaging it if it’s
not properly secured when powered on.
You should be good to go if you followed these instructions. Now go make some
noise!
A final note. Some modules have other headers — they may have a different number
of pins or may say NOT POWER. In general, unless a manual tells you otherwise,
DO NOT CONNECT THOSE TO POWER.

Input and output voltages
All CV inputs expect 0-5 V. All pots act as offsets and sum with the input CV. The FSU gate input responds to signals above +2 V. The audio inputs clip around 16 V peak to peak.
Interface
Blend: Dry/wet balance control. When turned fully left, the unmodified input
signal is passed through. Fully right, only the processed signal is heard.
Points in the middle give you a mix of both.
A good way to hear Blend is with high Regen values and Tone and Index set to
12 o’clock.
Tone: A filter in the reverb tank. This is a bipolar control: turning the knob
to the left controls a lowpass filter, and to the right controls a highpass
filter. In the center, the filter is disabled.
A good way to hear Tone is with high Regen values, and Blend and Index at 12
o’clock. Regen: Amount of feedback in the reverb tank. Regen controls a wide
range of tones and behaviors.
All the way to the left, feedback is minimized. As you turn up to about 12
o’clock, DV generates shorter reverbs, emulating smaller synthetic spaces.
Past this point, the reverb reaches 100% feedback, creating spaces with an
infinite tail. Past 3 o’clock, the infinite reverbs are ducked by new sounds at
the input, creating sidechain-type effects.
Speed: The speed of the internal LFO. The LFO can modulate the delay lines,
and modulation amount is controlled by the Index parameter.
A good way to hear Speed is with a low Size setting, Density and Index fully
clockwise, and a high Regen setting.
Index: The amount of LFO sent to the delay lines that make up the reverb. This
is a bipolar control: in the center the LFO is disabled. To the left, the LFO
modulates the delay lines randomly. To the right, the LFO modulates the delay
lines with a sine wave. The Speed parameter controls the rate of the LFO.
A good way to hear Index is with a low Size setting, Density fully clockwise,
Speed at 12 o’clock, and a high Regen setting.
Interface (cont.)
Size: The delay time of the reverb.
A good way to hear Size is with a percussive input and all other parameters at
12 o’clock.
Dense: The spacing of the delay lines. To the left, the effect sounds more like
a delay; to the right, the delays are smeared into reverb.
A good way to hear Dense is with a percussive input, Size fully clockwise, and
all other parameters at 12 o’clock.
FSU: This control maxes out the Regen control and mutes the input to the
reverb when the button is pressed, or when a high gate is sent to its input.
A good way to hear this button’s effect is with Blend above 12 o’clock and a
low Regen value.
In L/In R: Audio input. If R is not patched, the signal from L is normaled to
both inputs.
Out L/Out R: Stereo output pair.
LIM/DST/SHM: Reverb style.
- LIM (Limit): A clean reverb, using limiting within the reverb tank to contain feedback. A good way to hear LIM is with moderate Regen values and starting with all other parameters at 12 o’clock, then playing with Tone and Index/Speed.
- DST (Distort): Similar to LIM, but instead of limiting within the reverb tank, slight saturation is applied for a more distorted sound. A good way to hear DST is with high Regen values and starting with all other parameters at 12 o’clock, then adjusting Size and Tone to taste.
- SHM (Shimmer): A demonic pitch-shifting algorithm. Adds a one octave pitch shift that feeds back into the input. A good way to hear SHM is with high Regen values, and all other parameters at 12 o’clock. Create haunting effects by introducing subtle modulation with Speed and Index.
BND/LRP/JMP: Changes how the delay lines respond when the panel controls are modulated. To hear each mode clearly, turn Regen fully clockwise and modulate the Size parameter.
- BND (Blend): Crossfades the delay times for smoother changes.
- LRP (Interpolate): Slowly changes delay line length, has audible pitch shift effects due to the delay lines changing length.
- JMP (Jump): Quickly changes delay line length, for audible and fast changes.
Patch Tutorial
First patches:
For your first patch, use a simple, short sound, like a pulse, snare, or click.
Patch to In L, and patch Out L and R to your mixer. Set the Blend, Index, and
Tone controls to 12 o’clock to start, and play with Regen, Size, Dense, and
LIM/DST/SHM to get an idea of what DV is all about.
Use the Tone control to shape the reverb to your liking, and use the Index and
Speed controls to add some movement to your reverb.
Hold the FSU button to create an epic wall of sound.
Try patching a CV signal from a sequencer or other modulation source to Size.
Play with the BND/LRP/JMP switch to hear the different ways the reverb can be
modulated externally.
Unpatch your input, and turn Regen past 12 o’clock. DV will start to self
oscillate. Use the front panel controls to manipulate the tones it generates.
Drop it back to fully left to stop the self oscillation.
Simple delay:
Set Blend, Tone, and Index to 12 o’clock, Regen to 10 o’clock, and dense
fully counterclockwise. Play with Size, LIM/DST/SHM, and Tone to shape your
delay.
Kick ducker:
Patch a kick (or other percussive sound) to the input, and turn regen fully
clockwise. Set Blend to 12 o’clock and the other parameters to taste. Each
kick will duck the reverb, creating a rhythmic ambience.
Instant IDM:
Patch a modulation source like Clep Diaz to the Size parameter and set the
lower switch to LRP or JMP. Play with the rest of the parameters to get some
ridiculous delay modulation.
Updating Firmware
Desmodus Versio’s firmware can be updated by the user via our firmware webapp.
In the unlikely event that the need arises, firmware patches will be available
on that site. Alternate firmwares available now transform the DV from a reverb
into completely different modules, and open-source firmware development support,
DIY resources, and documentation are available here.
To update the firmware on your Desmodus Versio:
- Turn off the power to your case and unscrew DV.
- Remove the power connector on the back of DV.
- Plug a micro USB connector into the port on the pack of the module, and the other end into your computer.
- Follow the instructions in the webapp.
Desmodus Conservation
We’ve known for a long time that we wanted to do a reverb, and it seemed like
a pretty obvious opportunity for us to revisit our core values and support
another conservation charity. With a reverb module, bats seemed like a pretty
obvious connection: many bat species use echolocation, where they send out an
ultrasonic signal, and then listen for subtle shifts in the returned echo.
Those shifts can tell them incredible details about their environment,
including the location of prey — even while they are both moving!Bats are the
most species-diverse group of mammals, and critically important to ecosystems.
Insect-eating bats eat literally tons of insects annually, including those
that damage crops. One estimate says bats are worth more than US$3.7 BILLION
/year in reduced crop damage and pesticide use! They also pollinate a variety
of crops and disperse seeds for a lot of plants, including plants that we
humans are fond of. In addition, bats are in trouble. Habitat loss and other
human-made causes are among the biggest threats. And in North America, a new
fungal pathogen called White-nose Syndrome is killing bat colonies as they
hibernate (in some places, leading to complete devastation of colonies).
We’ve partnered with Bat Conservation International (www.batcon.org), the
global leader in bat conservation. We’ve committed to donate a portion of the
proceeds from every DV sold to bat conservation. That means you can pat
yourself on the back for buying a Desmodus Versio, knowing you’re doing some
good in the world! Want to know more about bats? Learn how to build a bat

Design Notes
We have wanted to make a reverb for a long, long time. Our biggest block was
always having a suitable computational platform. The platform we use for our
oscillators is phenomenal for oscillators but does not have enough storage for
most audio effects.
In mid-2019, Electrosmith sent us a platform that they were developing for the
DIY market to test and give feedback on. This platform would become the core
to the Daisy line that they now sell. The first nontrivial test we did with
Daisy was to port some of the reverb work that Stephen had been developing on
and off for years. Stephen performed at MOTS LA in the summer of 2019 with the
Daisy prototype running this reverb literally taped to the side of his case.
At that time, we were in the midst of designing our own platform similar to
Daisy (code named George) though after one iteration we decided that where
Electrosmith had decided to go with the Daisy Seed was going to be a suitable
platform for us so adopted the Seed for our hardware backend. The stars
aligned and we were pretty confident we were close to release by the end of
that year.
We announced Desmodus Versio at NAMM 2020. A few weeks later, we got the first
inkling that something was amiss when the factories in China (where we get
PCBs and parts) didn’t really return from the Lunar New Year holiday. It seems
like no time after that when the COVID-19 pandemic became official and 2020
became a year entirely out of our control. Releasing a new module no matter
how much anticipated became untenable for nearly six months (but we appreciate
all the emails desperate for the module!). Supply chains broke down,
California (and almost everywhere else) shut down, our manufacturing came to a
virtual halt, and our employees were sent to work from home sans new hardware
to test, since we didn’t yet have it. It took several months (and another
unexpected iteration or two) before we got to a point where we could actually
put Desmodus into production.
Oh and yes… Stephen grew as much of a beard as he is capable of for the
development of this product.
