Desmodus#

Synthetic tail-generator reverb and atmospheric creation tool

Overview#

Desmodus is Noise Engineering’s take on a reverb. This is a true stereo 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 Desmodus allow you to take the effect from a delay to a beautiful reverb to an uncanny, nightmarish atmosphere with the change of a few parameters. Desmodus isn’t a reverb: it’s an instrument on its own that’s designed to be played, and with an extensive modulation system, it’ll go beyond any effect you’ve heard before.

Shortcuts#

Cmd/Ctrl+Click or Cmd/Ctrl+Mouse wheel

For finer control, hold Cmd (Mac) or Ctrl (PC) while moving a parameter.

Double click

Resets any parameter to its default state.

Scroll

Hover over any parameter and scroll to adjust. Scroll+Cmd (Mac) or Scroll+Ctrl (PC) give finer control.

All of these work to edit step levels in LFO Step shape as well.

Tone page#

Volume In

Controls the level of sound coming into the Desmodus.

Volume Out

Sets the output level of the plugin.

Blend

Controls the dry/wet balance. 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.

Regen

Sets the 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. To the left of center, Desmodus generates shorter reverbs, emulating smaller synthetic spaces. Past 50%, the reverb reaches 100% feedback, creating spaces with an infinite tail. Past 75%, the reverb tails are ducked by new sounds at the input, creating sidechain-type effects.

Dense

Sets the spacing of the delay lines. At minimum the effect sounds more like a delay; to the right, the delays are smeared into reverb.

Tone

Controls a filter in the reverb tank. This is a bipolar control: moving the parameter to the left controls a lowpass filter, and to the right controls a highpass filter. In the center, the filter is disabled.

Time or Ratio

Sets the delay time of the reverb. When Sync is unchecked, the Time slider adjusts time in seconds. When Sync is checked, the Ratio fraction sets the delay time in beats.

Sync

Sets whether the delay is clocked in seconds or beats.

LFO Speed

Sets the speed of the internal LFO. The LFO modulates the delay lines; modulation amount is controlled by the Index parameter.

LFO Index

Sets 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.

Lerp Mode

Changes how the delay lines respond when the controls are automated.

• blend: Crossfades the delay times for smoother changes.

• lerp: Slowly changes delay line length, has audible pitch shift effects due to the delay lines changing length.

• jump: Quickly changes delay line length, for audible and fast changes.

Node Mode

Sets the reverb style.

• limit: A clean reverb, using limiting within the reverb tank to contain feedback.

• distort: Similar to limit, but instead of limiting within the reverb tank, slight saturation is applied for a more distorted sound. This is a very subtle distortion: to hear it clearly, set the Regen parameter to about 80%.

• shift: A demonic pitch-shifting algorithm. Adds a one-octave pitch shift that feeds back into the input.

Presets#

Presets are stored in the computer’s file system, and the controls below allow for modification and navigation through the files and folders of presets. You can create a new preset “Category” by creating a subfolder in the preset directory, and saving new presets within it.

load

Load a preset.

save

Save a new preset.

< > (category)

Loads the next/previous folder of presets in the preset directory.

< > (preset)

Loads the next/previous preset.

nudge

Applies a small amount of randomization to all tonal parameters and modes. Randomization can be bypassed per control in individual parameter modulation menus. Useful for creating slight variations of sounds.

rand

Completely randomizes all tonal parameters and modes. Randomization can be bypassed per control in individual parameter modulation menus. Use this to create inspiring new sounds and ideas.

reset

Resets all parameters to their default settings.

Modulation#

All Noise Engineering plugins feature a comprehensive routing system making use of a variety of modulation types and sources. When modulation is enabled on a parameter, a box showing the range of enabled modulation will appear, and a small indicator will move within the range box showing the exact position of the modulation.

Types of modulation#

Parameters can be modulated from a variety of sources:

LFOs

Four onboard LFOs that offer a variety of modes, from simple waveforms to step sequencers. More detail on LFO modes can be found in the section below titled “Modulation page.”

Macros

Four macro sliders can be assigned to any number of parameters. The macros can in turn be mapped to MIDI controllers, automated, or modulated with other LFOs.

Env

Envelope follower. Turns the dynamics of the incoming signal into a modulation source.

MIDI CC

Parameters can be assigned to MIDI CCs. (Note: MIDI mapping of effects is not supported in all DAWs.)

Modulation Assignment#

When a parameter is right-clicked (Control+click on Mac), a context menu appears with modulation routing options:

Parameter slider

A copy of the parameter being modulated, for easy adjustment.

On

Each modulation source has a checkbox; when checked, modulation from that source is enabled.

Index

Sets the amount of modulation from a particular source. Fully left, modulation is bypassed.

Dir

Direction. Sets the polarity and inversion of incoming modulation.

• --> (unipolar): modulates from the point selected on the parameter up to the level indicated by the Index setting
• <-> (bipolar): modulates around the center point set by the parameter
• <-- (inverted unipolar): opposite modulation from unipolar
• >-< (inverted bipolar): opposite modulation from bipolar

Curve

Each modulation source has a Curve slider that changes how modulation affects the parameter. In the center, modulation is linear, and the parameter movement matches incoming modulation exactly. To the right modulation is more logarithmic, and to the left more exponential.

Allow Randomize

When checked, this parameter can be randomized when “rand” (Tone page) is clicked.

Learn CC (only visible when MIDI Learn is checked on the Config > Interface page)

Click this to enable MIDI CC learn on a parameter. Move a parameter on your MIDI controller and the plugin will exit learn mode and the parameter will now respond to that CC. If clicked by mistake, click Waiting on CC to exit learn mode. Click Forget CC to remove an assignment.

Clear modulation

Resets modulation checkboxes, amounts, direction, and curve. Does not affect CC assignments.

Modulation Page#

Click the sections in the left column to navigate to that page and edit modulator settings and routings.

LFO 1-4#

Index

Sets the modulation range of the LFO.

Type

Sets the type of LFO. Options include Wave, Step, and ADR, described in detail in the sections below.

Sync

Sets the source of timing for the modulator. * Free: A single completely freerunning LFO; never resets. * Transport: Speed is set in seconds, but the LFO follows the transport of the DAW. * Tempo: A single LFO that is synced to the DAW’s tempo and transport.

Speed/Beats

Sets the rate of the LFO. In unsynced modes, this is a slider that sets the rate in seconds. In synced modes (Tempo and Poly Tempo), this is a fraction that sets the rate in beats (for example, 4/1 would be equal to 1 bar in 4/4 meter). If a synced mode is selected, the rate can be doubled or halved with the *2 and /2 buttons respectively.

Reset LFO

Resets the LFO back to its default state, respecting Type.

Type: Wave#

Shape

Morphs between different waveforms.

saw/sin/tri/sqr/was

Selects a shape preset for the waveform. Choose saw, sine, triangle, square, or inverted saw.

Phase

Changes the starting point of the wave.

0/90/180/270

Selects a preset for the phase of the waveform.

Time Warp

Skews the timing of the waveform.

Noise

Adds randomness to the waveform.

Color (only visible when Noise is above minimum)

Changes the intensity of randomness added to the waveform.

Type: Step#

Speed/Beats

Sets the rate of the sequencer. In unsynced modes, this is a slider that sets the rate in seconds. In synced modes, this is a fraction that sets the rate in beats (for example, 4/1 would be equal to 1 bar in 4/4 meter). If a synced mode is selected, the rate can be doubled or halved with the *2 and /2 buttons respectively.

Count

Sets the steps in the sequencer; the up and down arrows change the count by one, and the *2 and /2 buttons respectively double or halve the count.

Smooth

Adjusts how smooth the transition between steps is.

Time Warp

Skews the timing of the sequencer.

Random

Adds per-step randomization to the sequence.

Graph

Edit your sequence here by clicking and dragging or use the preset buttons: * rand: Randomizes the sequence entirely. * nudge: Slightly changes the values of each step. * up: Generates an ascending pattern across the steps. * dn: Generates a descending pattern across the steps. * ud: Creates a triangle pattern across the steps. * du: Creates an inverted triangle pattern across the steps.

Macro#

Mac 1-4

Four sliders that can be assigned to any number of other parameters, and modulated by LFOs or MIDI CCs.

Env#

Envelope

An indicator of the current Envelope modulator value.

Index

Sets the range of the Envelope modulator.

Clear#

Clear All Modulation

Clicking this removes all modulation routings from the patch. Use it wisely.

Clear All CC Assignments

Clicking this clears all MIDI CC mappings.

Route page#

When a modulator (LFO, Macro, or Env) is assigned to a parameter, the parameter will appear in this list when on that modulator’s page. For instance, if LFO 1 is modulating Blend, click LFO 1 on the left side to view the modulation amount, curve, and checkbox for Blend (and any other LFO 1-modulated parameters) on the right.

Group

Param

Selects a parameter from the current Group category.

Add Route

Adds modulation routing for the selected parameter from the selected modulator.

Clr Routes

Click twice to remove all modulation assignments for the current modulator. To remove a single assignment simply uncheck the On box.

Add Rand

Adds a random modulation destination.

On

Each modulation source has a checkbox; when checked, modulation from that source is enabled. When unchecked on this page, it is removed.

Index

Sets the amount of modulation from a particular source. Fully left, modulation is bypassed.

Dir

Direction. Sets the polarity and inversion of incoming modulation: * --> (unipolar): modulates from the point selected on the parameter up to the level indicated by the Index setting * <-> (bipolar): modulates around the center point set by the parameter * <-- (inverted unipolar): opposite modulation from unipolar * >-< (inverted bipolar): opposite modulation from bipolar

Desmodus history#

We have wanted to make a reverb for a long, long time. We dabbled a lot, but in hardware, our biggest block was always having a suitable computational platform. The most recent generation of microprocessors were finally what we needed and Desmodus went into the hardcore design stage in 2019. In late 2020, we released our DSP platform module, the Desmodus Versio, and it was a smashing success. We decided that as we venture into software, we wanted to bring that same reverb algorithm to the world of DAWs. After years of work in hardware and a bit more development bringing it to software we’re happy to introduce Desmodus: nicknamed the Batverb, it was designed to be unlike any reverb on the market.

After Desmodus’s release, we got a few requests for a tempo-syncable version of Desmodus. After a bit of development, Electus Versio was born as a variation of Desmodus with a similar sound and featureset, but with a clock input and divider/multiplier.

The Desmodus plugin includes all features from both Desmodus and Electus Versio.

About NE#

Noise Engineering is located in Los Angeles, California. We started around 2014 when Chief Noisemaker Stephen McCaul wanted a hobby for his off time from his day job and started making Eurorack modules in a spare bedroom at home. One thing led to another and a couple of years later, he and wife Kris Kaiser quit their day jobs and took the company full time. Noise Engineering has since grown in size and has established itself as a well-regarded and innovative synthesizer brand, with products in Eurorack, 5U, and multiple software platforms.
