Introduction
Waves MDMX Distortion Modules
Waves Modern Distortion Modules (MDMX) is a toolkit that includes three separate plugins: Screamer, Overdrive,
and Fuzz. It’s designed for musicians, engineers, and producers who need top-notch distortion and overdrive effects
for instruments or mix busses. These three plugins run the gamut of distortion effects, from subtle to scorching.
•MDMX Fuzz is the most aggressive MDMX plugin. It can track the distortion signal in octaves, apply dynamics
and octaves ahead of the distortion processor, and color the distorted signal. Bottom line: a big, in-your-face
distortion effect that lets you go as far as you want.
•MDMX Overdrive is similar to MDMX Fuzz, but with less coloring. Like Fuzz, it can do a number on an
instrument, but Overdrive is generally a bit gentle.
•MDMX Screamer is a straight-ahead overdrive generator. It generates subtle to strong overdrive, while
holding on to the sound of the instrument or track.
Each of these three plugins is described in its own section of this user guide.
MDMX stereo components give you the choice of distorting the entire stereo signal, or the center or sides. This
provides great control when fitting an instrument into a mix and it lets you change the way a sound relates with the
space around it.
There are other Waves plugins that use distortion as a creative tool or to weave a sound into a mix:
•Berzerk is a wide-open distortion tool that lets you build effects from scratch. It combines distortion,
dynamics, feedback, and distortion character control with a random generator. It’s made for engineers,
producers, and sound designers.
•To bring a “too clean” track to life, add a bit of precise distortion with the Abbey Road Saturator plugin. The
effect might go unnoticed, but the instrument or track will have more sparkle and will sit better in the mix.
Saturator is not shy; when called upon, it can also add real attitude to an instrument.

Using MDMX Presets
Each MDMX plugin comes with an assortment of factory presets. In many cases, you’ll find just the right effect by
loading a preset. Sometimes you’ll load a preset as a starting point and then make adjustments to achieve what
you’re after. Starting with a preset has two advantages:
•It’s fast. We’ve already done most of the work needed to produce a specific sound. Begin with a preset
whose name sounds like what you’re looking for and tweak a few controls. That might be all you need.
•It’s a good way to learn. Load a few presets and see how the controls are set for each one. Pay attention to
how the different settings influence the sound. Do this a few times and you’ll understand what the controls do
and how the sections work together.
Each module has a section in this user guide called “Using Presets.” It shows you how we address some common
distortion and overdrive issues using that tool. You can, of course, design an effect from scratch, without using a
preset.
Once you like the sound you’ve created, you can save the settings as a preset. This is important if you want to use
the preset in other sessions or elsewhere in the current session. Go to the Save menu in the WaveSystem Toolbar
at the top of the interface and select one of the save options. Refer to the WaveSystem User Guide for more
information.

Mono Component
Stereo Component
MDMX: Fuzz
Waves MDMX Fuzz is a distortion tool with an attitude. It can provide a huge amount of distortion with a surprising
amount of control. Its distortion shaper, synthesized octaves effects, dynamics and EQ sections, and M/S processing
let you take distortion as far as you like without completely losing touch with the soul of the instrument.
In general, signal flow is: Input->Dynamics->Gain->EQ->Output. The Dynamics section loops back to the Gain
section.
Components
There are two MDMX Fuzz components: mono and stereo.
The mono and stereo components
are the same, except for the number
of channels. Note that the mono
component does not have a Stereo
Mode select. Both components use
very little CPU, even when up-
sampling.

Getting Started
Using MDMX Fuzz Presets
In many cases, you’ll find just the right Fuzz effect by loading a factory preset whose name makes sense, based on
what you want to accomplish. More often than not, you’ll need to load a few presets until you find one that’s a good
match, and then adjust the controls to your liking. Save the settings as a user preset. Here are three Fuzz factory
presets that help you find your way when you’re creating a distortion effect. All three use the octave up/down control
to brighten, thicken, or increase the disorder of a track.
PRESET:OCTAVE UP
Issue: You want to brighten or add excitement to the source
Particular to Fuzz is the up and down octave generator that lets you quickly add and mix octaves to the distortion. When a
distortion signal is too dark, add sparkle as a part of the distortion, rather than with the EQ section, which is after the distortion
in the signal flow. Try both, the result it quite different.
Move the metal button in the octave pad to change the mix. The further to the right, the more jagged the effect.
PRESET:OCTAVE DOWN
Issue: You want to thicken the sound without making it too dark.
As with Octave Up, this preset is all about the Octave pad. Here, however, we want to add weight. By mixing in some of the
generated octave down signal, we can add bottom end while maintaining transparency. Move the Octave button left and right
to explore the effect on the low frequencies. Alternatively, adjust the low shelf in the EQ section. As you increase the low
frequency, the sound is thicker. These are two very different effects.
PRESET:OCTAVE BOTH
Issue: You want to add disorder to the track without altogether losing its personality.
This preset is, in essence, a collision of the last two examples. It combines the sizzle of Octave Up with the weight of Octave
Down. The result is a bit nutty, especially if the left and right channels of the input are significantly different.

Getting Started from Scratch
You may choose to forgo presets and build your own Fuzz effect from scratch. Open the plugin and start turning
knobs. It’s very likely that you’ll do just fine on your own, but we suggest that you first get to know the plugin by
following these steps.
INPUT SECTION
Adjust the Input level. A LED above the input knob indicates peak level. In the stereo component, the Mode
switch lets you select which part of the sound image to distort: mid, sides, or entire stereo image. If you’re
focusing the distortion effect on the mid or sides, use the small input control to adjust that level relative to the
overall input level. There’s also a low-cut filter that you can use to reduce rumble in the input signal or to change
the character of the distortion.
GAIN SECTION
Use the Gain knob to adjust the amount of generated fuzz. Choose between two basic shapes: A or B. The
selected waveform is shown on the right. Use the round control on the left to adjust the synthesized one-octave-
up and one-octave-down signals.
DYNAMICS SECTION
Control dynamics of the signal sent to the Gain section. Choose between a compressor (Punch) or a gain rider
(Rider). Blend is the mix between the input signal and the processed dynamics signal going to the distortion
generator.
EQ SECTION
Adjust the tone of the signal from the distortion generator. The EQ feed directly to the Output section.
OUTPUT SECTION
Mix is a wet/dry balance between input and processed signal, Output sets the output of the plugin, and
Temperature controls the overall color of the output signal. Make sure not to clip the signal that’s returning to
the DAW.
If you don’t like the way things are going, it’s probably better to start over than to keep fixing your fixes. Choose
“Fuzz Full Reset” in the Load menu to return all controls to their factory reset values. Once you’re happy with the
sound, create a user preset in the WaveSystem Toolbar.

Interface and Controls
Processing Sections
Input sets input level from the DAW.
Gain controls the character and amount of
fuzz generated. It includes a one-octave-up
and one-octave-down generator whose
signal you can combine with the distortion.
Dynamics (center) controls the dynamic
processing of the signal sent to the Gain
section.
EQ provides four-band equalization, post-
Gain and post-Dynamics.
Output sets the level of the return to the
host. It also lets you define the temperature
of the output sound and control the dry/wet
mix.

Controls
Input Section
INPUT GAIN
Controls plugin input level. The input level can have a dramatic effect on
the behavior of the plugin. Experiment, too, with the level of the signal
being sent from the DAW.
The small light next to the Input knob indicates input peak level. Green
generally indicates a healthy level. An occasional red flash is unlikely to
create unwanted internal clipping, but reduce input gain if the peak is
consistently red.
Range: -24 dB to +24 dB
Default: 0 dB
LOW CUT
Controls the amount of low-shelf attenuation before the signal is sent to
the distortion generator. Higher settings tend to deliver more clarity. Lower
settings typically yield a warmer sound.
Range: Off, -12 dB, -24 dB
Default: Off
Tip: You can largely prevent low frequencies from being distorted without losing low frequency power. Select a
-24 dB low cut and then add back some of the lows using the low shelf in the EQ section. Input is pre-distortion,
while EQ is post-distortion, so the lows are removed before processing and added back later. This helps
prevent the very bottom of the input signal from mudding the distortion, plus, it’s a different sound.

MODE
Sets how a stereo signal be processed:
•In Stereo mode, both channels of a stereo signal are processed, so the middle is processed in the same manner as the
sides.
•In M mode, the middle of the stereo image is distorted. The sides are not processed.
•In S mode, the sides of the stereo image are distorted. The middle is not processed.
MID OR SIDE MODE INPUT LEVEL CONTROL
When the Input section is set to Middle or Side, this knob controls the input level of the M or S signal, independent of the
plugin input. A letter following “Input” identifies whether M or S is being controlled. When Stereo input is selected, this control
is grayed out.
Range: -24 dB to +24 dB
Default: 0 dB

MDMX Fuzz
MDMX Distortion Modules / User Guide
12
Gain Section
The Gain section is where distortion is generated.
GAIN
Controls the amount of fuzz distortion.
Range: -24 dB to +16 dB
OCTAVE
The distortion generator creates signals one octave above and one octave
below the input signal. This mimics analogue octave devices, and by design,
does not precisely track pitch. These signals can be mixed with the primary
distortion signal.
Use the round control on the left side to adjust the mix of these octave
signals. Move the silver ball side to side to control the mix of the octaves;
move up and down to add more or less of the total octave signal.
TYPE
There are two basic models of fuzz generation, which are built around
different waveform shapes. The effect varies depending on other settings.
But in most cases, this control strongly influences the basic sound.
Range: A or B
WAVEFORM DISPLAY
The display on the right shows the waveform as defined by the Type selection. It changes as the Gain control is adjusted, but it
maintains its basic shape. The waveform is also influenced by activity in the Dynamics section.
HD ON/OFF
Engages x8 up-sampling of the distortion signal. With low resolution files, low and high frequency parts of a signal tend to
collapse, and the effect can be perceived as too edgy and narrow. Up-sampling provides more room for processing and can
result in a more pleasant, wider sound. When HD is Off, you will likely get a grittier sound.
This effect is very program-dependent, so in certain cases you may not hear a difference.

MDMX Distortion Modules / User Guide
13
Dynamics Section
The dynamics section controls the dynamic characteristics of the signal sent to the Gain section. There are two
dynamics processing modes: Punch and Rider. When one mode is selected, the other mode’s control is inactive.
Punch mode is a fixed-ratio compressor with the three increasingly
aggressive presets (comprised of knee, attack, and release settings).
Range: Mild, Moderate, Extreme
Default: Mild
Rider mode controls which parts of the signal will be sent to the Gain section
for distortion processing. At high threshold settings, only the loudest peaks
will be sent. As threshold is lowered, more of the lower-level signal is sent to
the distortion generator.
THRESHOLD (Rider mode only)
Range: 0 to 100
Default: 100
BLEND
This is the balance between the dynamics section and the output of the overdrive generator.
Range: 0 (no dynamics) to 100 (full dynamics)
Default: 0

MDMX Fuzz
MDMX Distortion Modules / User Guide
14
EQ Section
The EQ section is a four-band equalizer that applies an EQ after the distortion generator and dynamics processor. It
feeds directly to the Output section.
There are four fixed-frequency bands:
Low: low shelf, fixed frequency
Low Mid: bell filter with three frequency settings (A, B, C)
High Mid: bell filter with three frequency settings (A, B, C)
High: high shelf, fixed frequency
Gain range for all bands: -12 dB to +12 dB
Default gain for all bands: 0 dB
Output Section
The Output section is the end of the plugin’s chain, so its three
controls are post-distortion, post-dynamics, and post-EQ.
TEMPERATURE
Controls the warmth of the output signal. Higher settings are darker and
fatter and can appear as more distant. Lower settings are usually more
present, with more “sparkle.” The EQ section and the Temperature control
do not have the same effect on the final sound, so experiment with both.
Range: 0 to 100, Default: 50
MIX
Controls the balance between the processed signal and the dry signal.
Range: 0 to 100, Default: 0
OUTPUT
Sets the output level of the plugin.
Range: -24 dB to 24 dB. Default: 0 dB

MDMX: Screamer
MDMX Screamer is all about overdrive, the kind of the overdrive sound that you hear when an amp is oversaturated.
It can sound very fat and round and it’s not particularly spikey. It’s well suited for helping an instrument stand out in a
mix or giving it a bit more attitude. Screamer is simple, yet surprisingly flexible. There are controls for input gain,
overdrive amount and boost, overall tone, and output, which give you the tools you need to produce rich, complex
overdrive effects.
Components
There are two Screamer components: mono and stereo.
The components are identical
except for the number of
channels. Note that the mono
component does not have a
Stereo Mode select control.

Getting Started
Using MDMX Screamer Presets
Screamer doesn’t have a lot of controls, so you will most likely learn it through trial and error. Nonetheless, presets
give you a head start and make for more trial and less error.
Here are two presets that use Screamer to change the weight of an instrument or track.
PRESET:FAT
Issue: The source is thin and shrill.
This preset opens with most of the controls in their default position—it’s all about Tone and Gain. Since you want to warm up
the source, keep Tone at or near its lowest setting. As you turn the knob clockwise, the sound thins out—probably not what
you’re after here. Spend a moment with the Gain control. Backing off on the Gain by a tiny amount will likely give you more
body.
PRESET:MORE!
Issue: The effect is good, but there’s not enough gain.
Like its cousin Fat, this preset opens with most of the controls in their default position. The three controls that concern us here
are Gain, Boost, and Tone. Boost provides 6 dB of overall boost on top of a midrange boost. Adjust the Gain until you find a
good balance between saturation effect and weight. Similarly, use Tone to find a color that does what you need but doesn’t
add unnecessary thickness.

Getting Started from Scratch
You can, of course, skip the presets and head straight for the controls. Open the plugin, start turning knobs, and see
where it takes you. That usually works pretty well. We suggest, however, that you first get to know the plugin by
following these steps. It’s a pretty logical way to work, and it helps you to isolate what each section is doing.
INPUT SECTION
Use the Input knob to adjust overall input level. Peak input level is shown on the adjacent LED. An occasional
red blink will likely not indicate trouble, but continuous red can cause gain problems down the line. The M, S, and
ST buttons let you select which part of the stereo image to process: mid, sides, or the entire stereo image. If
you’re focusing the overdrive effect on the mid or sides, use the second input control to adjust that level.
SHAPER SECTION
Use the Gain knob to adjust the amount of overdrive introduced to the signal. Boost adds 6 dB of gain and a
mid-frequency boost to the overdrive signal. Adjust the Tone control to set the bass/treble control, as on a hi-fi.
This changes the color at the core of the sound in the overtone generator.
OUTPUT SECTION
Adjust the acoustic characteristics of the sound with the Temperature control. This control is not the same as the
Tone control. It’s more subtle and has a greater effect on the “air” around the sound. Experiment with both of
these controls. Finally, adjust the wet/dry Mix and set the Output level. When the output LED is constantly red,
you are hitting the output limiter too hard.
If you don’t like the way things are going, it’s probably better to start over than to keep fixing your fixes. Choose
“Screamer Full Reset” in the Load menu to return all controls to their factory reset values. It’s a good idea to save
your settings as a preset before resetting the plugin. Who knows, maybe you were right after all.

INPUT CONTROL
Controls input gain. Experiment, too, with the level of the signal being sent from the DAW.
Range: -24 dB to +24 dB
Default: 0 dB
MODE SWITCH (M, S, ST)
Sets how a stereo signal will be processed:
•In Stereo mode, the entire stereo image is processed, so the middle of the image is processed in the same manner as
the sides.
•In M mode, the middle of the stereo image is distorted. The sides are not processed.
•In S mode, the sides of the stereo image are distorted. The middle is not processed.
This lets you choose between an overall distortion or an effect that focuses or defocuses the middle of the image. Processing
only S or M helps an instrument to “pop out” or “sit” better in a mix without excessive EQ or dynamic processing.
Default: ST

GAIN
Controls the amount of overdrive generated by the processor.
Range: 0 dB to +16 dB
BOOST
Adds 6 dB of overall gain plus 6 dB of mid frequency gain. It adds saturation to the signal.
Range: on or off, Default: off

MDMX Screamer

TONE
Changes the treble/bass color of the overdrive signal as it’s being processed. This changes the color of the distortion itself, so
has a big influence on the “core sound.”
Range: 0–100
Default: 50
HD ON/OFF
(On) enables x8 up-sampling of the output signal.
With low-resolution files, low and high frequency parts of a signal tend to collapse, and compression can be perceived as edgy.
Up-sampling provides more room to these parts of the signal and can result in a more pleasant sound.
When HD is Off, you can usually get a grittier sound.
Range: On or Off
Output Section
TEMPERATURE
Adjusts the overall color and feeling of the output of the plugin. Higher settings generally result in a roomier, darker, and
smother sound. Lower settings usually provide more presence and more articulation.
Range: 0–100
Default: 50
MIX
Controls the balance between overdrive processing and the dry signal.
Range: 0 (all dry signal) to 100 (all processed signal)
Default: 100
OUTPUT
Sets the output gain of the plugin. The LED shows peak output level. A red light means that the signal is activating the output
limiter (-0.9 dB), so if the LED is constantly red, reduce the output gain. Excessive limiting will change the texture of the output
audio. This is not necessarily bad, but you should be aware of it.
