Notes: Chimera is a granular synthesis module that specializes in drum sounds. It offers a wide range of detailed sample sources as well as its own synthesis engine. Firmware updates can be performed via USB.

The module features various samples called Surfaces. The samples are mainly metallic sounds:

Tambourine
Bells
Drill
Wrenches
Cartridge cases
Coins
Chains
Metal housings
Broken modular front panels

Chimera uses impulsive sounds with lots of detail and long decay times to create detailed shaker-like sounds. The granular synthesizer was developed around the samples here, this has the advantage that the percussion sounds sound so more natural.

Power consumption: 63mA at +12V and 17mA at -12V

Notes: Another update for WMD's clever dual VCA, this time a little bigger to give more control. Digital control of CV and attenuation gives lots of creative options. Third time's a charm.

Supplier's Notes:
WMD have done several designs of this circuit over the years, the first one had no knobs, the second was too small, the MKIII is finally how this circuit should be packaged. This module does some really cool stuff and is super useful in any system.

The Digital VCA lets signal through like a normal VCA, but the CV and attenuation level is controlled digitally. This lets us do things like wait until there is a zero crossing to change the amplitude, resulting in clickless amplitude changes.

The Trigger mode causes the VCA to only update when a trigger is received. The addition of a noise circuit for each side let us do a very quick and easy sample and hold that never droops. With no input, 5V is normaled to the attenuator, so you get a 0-5V sample and hold. In Bipolar mode, you can get -5 to +5V.

Both sides have bipolar VCA mode (polarizer), which lets them invert the signal when negative CV comes in. Also known as ring modulation. With the zero crossing detector, this can produce some super wild wave shapes.

Notes: Originally inspired by audience applause, hip-hop samples, and classic drum machines, Fracture is a multi-particle percussion synthesizer that applies concepts from classic analogue clap circuits to granular synthesis methods.

It all starts from proprietary micro-samples we recorded specifically for this purpose and ends with an engine built to suit these samples.
Unlike our other percussion module, Chimera, which uses impulse rich samples as it's tonal center, Fracture uses single impulse samples like claps, snaps, ping pong balls, opening a beer can, and many more. It then plays a group of similar samples back in a psuedo random order for unique hits. Density, Decay, and Tail affect tone and how "tight" your virtual clappers are to playing together.

Our goal was to design a clap percussion module covering the range from classic drum machine claps all the way to full audience applause. We ended up with a module that covers a huge range of timbres beyond claps. We hope this engine provides you with the tools to intuitively create wild percussion sounds that bring your system to life in a new way.

Notes: Updated version of WMD's exceptional performance mixer. Full stereo design with improved sound quality, revised layout and increased expandability. An even better version of what was already one of the best mixing solutions in Eurorack.

Supplier's Notes:
Enter the WMD Performance Mixer MKII - Eight years after the MKI was released, the MKII builds on all the valuable feedback received. This is a serious upgrade, with feature enhancements and engineering improvements affecting every bit of the design.

Decisions, decisions, decisions!

If you recall, WMD showed a previous version of the PM MKII a year ago. That version was very similar to the original, with a few enhancements. Primarily focused on manufacturability and overall noise floor with some great recording features. WMD moved to an 8-layer board, replaceable channel strips, developed the MIDI and bootloader, pre/post fader headers, and made it work on both AUXs simultaneously.

Noise Performance - The MKI was alright with noise, there was a little bleed too. Going to 8-layer boards meant I could put ground planes between trace layers, and spread the traces out triple the spacing of what they were on the MKI, this reduces bleed/crosstalk by a factor of about six.

Noise Performance 2 - On the Original, the Level VCA was before the Panning VCAs, which saved on parts/power, but it meant that the Panning VCAs were always connected to the mix bus, adding noise floor that couldn't be attenuated. Making all the channels stereo and putting the Pan circuit first eliminated this problem, now the noise add is controlled by the fader. This did force WMD to make every channel stereo, so the design got simpler through figuring this out.

Panning / Crossfader - The above panning/level improvement made it possible to convert the Pan control into a crossfader, buy simply routing the post pan signals through a switch to the opposing channel, summed at the Level control. This huge improvement allowed the A/&/B input switching scheme to still work on the PM MKII, a bit differently, but it's there in spirit.

Modular Design - The channel strips are all now stereo, and identical, which makes assembly much easier, and lowers the cost. It also makes replacing them easier should a mechanical part fail or get spilled into. Further, the Patchbay, Power board, and Master section are all separate parts, so if there's a failure, they can be quickly swapped without having to RMA the whole unit.

Patchbay - The MKI and rev E MKII still had jacks misaligned with channels. This was a source of frustration for d many users of the PM MKI. And I decided to just be done with it. It didn't make sense to try to put jacks over the channel, it wasted too much space on the panel... So all the jacks go left, keeping the mixer clear of cables, this let me space the knobs out a bit to take up all 3U. It's cleaner, simpler to make, and intuitive to use.

Expandability - It's super modular now, the DB25 can connect to any two headers that spits out audio, they're all the same format across PM MKII and Channels MKII. Pre, post, mixes, connect it however you want. And the connectors can't be hooked to power, meaning no more blown opamps and RMAs to the factory. They're all shrouded too so they won't get bent in shipping!

Features Overview:

Everything is stereo. Inputs, Busses, Auxes, and Cue Mix.
INPUTS: IN LEFT is normalled to IN RIGHT.
GAIN: Each channel has a Gain trim range of -12dB to +20dB, this will let you use line level devices easily.
GAIN CLIP LED: lights red 1dB before clipping the input stage.
LVL FADER: smooth intuitive curve for easily adjusting the mix level on the fly. A yellow indicator shows the level.
MUTE: Press the channel button and the channel will soft mute with a red LED indicator.

Notes: Upgraded version of WMD's excellent performance mixer module, the PM MKII features four stereo or dual mono channels, CV control of levels, panning and aux sends, plus soft mutes per channel.

Supplier's Notes:
Need More Inputs?

Add four channels at a time to your Performance Mixer MKII setup, or you can use the Channels MKII as a standalone four channel mixer.

The expansion is simple -- identical channels, just more of them. Four at a time, up to four Channels units, for 24 total stereo channels.

A simple 16 pin 2mm pitch expansion cable is provided and is the only connection necessary. Units can be daisy-chained easily resulting in a clean setup.

Additionally, the outputs on Channels MKII still work when connected to the PM MKII. So you get a submix of AUX1, AUX2, and MIX available for whatever you may want to do, drum submixing, FX routing, etc.

Not Just an Expansion -- Standalone Operation
As a standalone unit, you get three stereo outputs, MIX, AUX1, AUX2. The buttons are soft mutes. It's a robust four channel setup.

FYI -- You can not connect CHANNELS MKIIs together without a PM MKII. The summing, buttons, and control brain is in the master section of the PM MKII.

Recording Outputs:

Pre and Post fade headers are available on the rear for connection to the DB25 MKII. Each Chanels MKII will fill 1/2 of a DB25 with the Pre or Post connections.

Specifications:

24HP
36mm Depth behind Panel Including Cables
Board Height Between Rails 111.5mm
Channel Input Gain: -12dB to +20dB
Fader Gain: -100dB to +5dB (Applies to Aux1, Aux2 also)
Pan Curve: -100dB at Hard L/R, -3dB at Center
All Inputs and Outputs (Including Sends, Inserts, Headers, etc) are IN PHASE
HPF: -1.3dB at 20Hz

Notes: PM DB25 MKII is an expander output for the MKII versions of the Performance Mixer and Channels.

Pre-fade and Post-fade connections are available for all channels. The DB25 has 16 outputs. All mixer channels are stereo, so one DB25 handles the main PM MKII (either pre or post), and the DB25 can handle 2x Channels (either pre or post).

Simply connect the cable to the Pre or Post headers on the back of the PM MKII or Channels MKII modules to choose pre/post.

The PM MKII has an additional header with both Aux Sends, Master Bus, and Submix Bus.

Connect a DB25 cable of your choice to the front connector and then straight to your DAW or recording interface.

For use with original WMD Performance Mixer, an adapter board can be added on. Please note that width behind panel is increased by 8mm when adapter board is added on. This may require some clever position in your case. The original Performance Mixer still only offers Pre Fader Outputs.

Notes: AXXENT is an expander module for the METRON trigger and gate sequencer and adds 16 "accent" gate outputs. Each track is specifically tied to METRON tracks, making it a very intuitive addition to any METRON sequencing ecosystem.

Use AXXENT to send signals to additional envelopes, slews, drum accents, and other gate triggered functions.

METRON will need its Firmware updated to support AXXENT.

Dimensions:
Width: 4HP (20.32mm)
Height: Eurorack 3U (128.5mm Panel, 112mm PCB behind panel)
Depth Including Cables: 43mm

Do not connect power to expansion headers.

Notes: Protect the faders on your favorite modules while making them more comfortable to use at the same time!

Perfect size for modules like the WMD Performance Mixer, Malekko Voltage Block, STG Graphic Sequencer, TTSH, Roland JU-06, and more. Custom sized to fit faders snug and clear in color so you can still see the LED indicator. The WMD clear fader cap is a must have for any module with plastic faders.

Notes: After five years of conceptualization, development, stress, company destruction and relocation, redesign, existential questions, prototyping, and willpower, WMD's Skorpion is ready to decimate and reanimate whatever you throw at it -- creating goosebump worthy sounds you've never heard before.

Skorpion is the epitome of WMD's ethos, "New Sounds, Maximum Experience". Painstakingly designed UI, all the CV I/O and controls you could ask for, and a broad spectrum of subtle to 100% NOT subtle swarms of harmonics, chaos, and character. This module is packed full of features to provide continuously explorable fun whether you are experimenting or meticulously crafting a sound that is 100% yours.

Skorpion builds on WMD's's long pedigree of experimental module designs, exploring a new method of wavefolding using thresholds and target voltages to control a powerful vector core. The design process has been very technically challenging, using high speed cmos and precise analog design with hybrid digital overlay for a solid UI.

Skorpion is an 8-stage analog wavefolder that allows you to precisely mangle simple waveforms into complex shapes with a fun, hands on fader interface. Taking the concept many steps further, internal modulation sources allow for macro animation of multiple parameters simultaneously, creating rich, evolving harmonic movement never heard before in hardware.

The Controls

The SHAPE and SLOPE controls allow for smoother or harsher added harmonics, and the 1V/OCT CV input is required for tracking timbre across notes.

FOLD controls the input gain of the signal, causing it to hit each of the eight THRESHOLDS causing a reversal in the output at each point. The signal can be driven towards one of three TARGETs: 5V, the Sliders, or the signal at the CLIP jack (normalled from IN).

SLOPE controls the baseline rate of the output, the higher the slope, the higher the harmonics. The overall slope rate is modified by 1V/OCT and SHAPE.

SHIFT is the classical vertical shift that makes the wavefolder sound like a chorus with subtle modulation.

SHAPE is a feedback control affecting the slope rate of the wavefolder. Eight different sources are available for feedback. The SYM switch decides whether the modulation is applied symmetrically when above or below 0V.

OUTPUT controls whats at the output jacks, the DRY signal, the WET signal, or a mid side stereo processed WIDE signal. WIDE is generated using a second vector core with a variable short delay. If all THRESHOLDS are inactive, a gate is normaled here. The intention being that if the input signal is too low to cause any folding, the OUTPUT circuit is pulled DRY so that you never get silence from the Skorpion.

The EQUALIZE THOLDs switch disables the sliders and forces an equally spaced threshold more akin to classic wavefolders. Modulation is disabled in this mode. Also controllable with a jack.

TARGET ORDER determines which slider is selected when the threshold is activated. Basically, it allows for a different order on the way up as way down producing pleasingly different timbres when using the sliders for target.

SYNC has three modes, OFF in the center. HARD which resets the vector core to 0V at every zero crossing of the input waveform. and SOFT which vectors core toward 0V at the current rate.

HALT IF TARG=0 makes the vector core draw a horizontal line if the TARGET slider for that threshold is at 0 (fully down).

ANIMATION - Sliders, Spring Action Switch, and Macro Envelope:
There are 13 total internal modulation sources. A primary MACRO ENVELOPE, eight (8) Threshold LFOs, and four (4) CV modulators that normal to the FOLD, SLOPE, SHIFT, and SHAPE attenuverters. The CV modulators can be LFOs or Envelopes.

The switch rests in the center, making the sliders control the THRESHOLDs. When held to the left, the sliders set the TARGETs. When held to the right, the sliders control the MACRO SETUP detailed below.

The MACRO ENVELOPE is an Attack/Hold/Release style envelope. A gate here will start the envelope, lighting the LED blue, while the envelopes level will glow red. The times for Attack and Release are controlled in the MACRO SETUP mode by the first two sliders.

The MACRO ENVELOPE modulates the amplitude of all LFOs. If the CV modulators are set as envelopes, then the gate will start the envelopes, but they otherwise operate independently.

MACRO SETUP:

Parameters are modified in MACRO SETUP by holding the switch to the right and moving respective sliders.

Macro Envelope's Attack Time
Macro Envelope's Release Time
Threshold LFO Amount
Threshold LFO Rates
Fold LFO/ENV Rate/Time - CV(5)
Slope LFO/ENV Rate/Time - CV(6)
Shift LFO/ENV Rate/Time - CV(7)
Shape LFO/ENV Rate/Time - CV(8)
Envelope Times are shortest at the bottom of the slider and longest at the top.

LFO Rates are slowest at the bottom of the slider and fastest at the top.
