Notes: The LedPressor is a full stereo Diode-based compressor module.
Its unique core adds character and color to any signal passed through it.
The LedPressor can be used as a normal compressor with low input levels, but as the input volume increases and the "nuke" LED lights up, it enters a new territory that combines compressor and overdrive, creating a dynamic overdrive effect.

Get it pumping with the Side Chain
The module features an external sidechain input that accepts audio and CV signals. Only the sidechain signal passes through a high pass filter, which gives the user greater control over the sound shape. The audio signal itself is not affected by the filter.
Parallel compression
The module also includes a mix knob that can be controlled with a dedicated mix CV input, allowing for greater flexibility when blending dry and wet signals. Additionally, it features a momentary bypass button to easily adjust the levels of dry and wet signals.
Feed-Back Or Feed-Forward - it's your choice
The module can be configured with a feed-back or feed-forward topologies with a jumper in the back.
Reverse polarity protection
The module have proper reverse current and over current protection in its power input stage to protect the module in case it was connected the wrong way or connected to a faulty power supply.

Notes: EME (Eloquencer MIDI Expansion) is the perfect companion for the Eloquencer, adding capabilities to sync with MIDI devices, control most of the eloquencer parameters with MIDI interfaces, generating MIDI voices from the eloquencer tracks, and converting MIDI signals to the eurorack world.

Description:
MAIN FEATURES
IN / OUT
DIN-5 MIDI Input, DIN-5 MIDI Output, USB Host.

BUTTONS
4 freely assignable buttons. They can be assigned to:

Next/previous pattern
Next/previous part
Direct access to Pattern mode, Play parts, Duplicate, Project, Gate REC, CV Key REC, MIDI key REC, Free Play...
Save current project
Random 1 to 3 layers of selected track
Reset LFO of selected track
On/Off LFO of selected track
Freeze
Revert
Fill A to H or selected track
Mute A to H or selected track
DJ Nudge FWD/BCK fine/coarse

MIDI CLOCK
Eloquencer can receive 24ppqn sync from MIDI device from its DIN-5 MIDI Input, and can send 24ppqn MIDI clock through its DIN-5 MIDI out.
When working as 'internal' it will send the internal clock to the MIDI output.
When working as 'external' will send the eurorack incoming clock to the MIDI output transformed into 24ppqn.

MIDI OUT
The Eloquencer tracks can be independently assigned to:
- Voice events (note on/off, velocity, ch pressure...) For example Track A can be assigned to Channel 1 Note on/off and Track B can be assigned to Channel 1 Velocity, so track A gates and CV control Channel 1 notes and pitch, and track B controls Channel 1 Velocity.
- Control Change (CC)
- Program Change (PC)

The gate and CV output will work as usual when a MIDI OUTPUT is assigned, so voices can be doubled using the modular and an external synth.

There's a particular execution order for MIDI out events, so the first to be launched is the Program Change, followed by the CC and then the voice events. This way, we can launch program changes before the note on message is received allowing preset changes for each step.

MIDI IN
Both, the DIN-5 MIDI in and the USB can be used to change eloquencer parameters using controllers or to introduce notes in REC MODE using a keyboard.

There are 3 different groups of controls associated to MIDI channels:
- Channel : 8 MIDI channels to control parameters of specific tracks from A to H
- Global : 1 MIDI channel to control Global parameters.
- Focus: 1 MIDI channel to control the parameters of the currently selected track (track in focus). That means that if Track A is selected and we send CC 38, we will be shifting track A, but if we select track B and we send the same CC 38, we will be shifting track B.

When using the USB host input, the EME can send feedback information in case the controller that is being used has LEDs to be updated.

There is a big amount of eloquencer parameters that can be controlled using an external MIDI interface / controller. For example:

Non-destructive track parameters addition/subtraction (CV, CVP, CVR, GL GLP, R...)
Track length
Step mode / Step mode DIV / Step mode REP
Track shift
LFO on/off / Type / Length / amplitude.
Fill
Mute
Random
CV Gate link
Scale group and root
Tempo
DJ Nudge
Shuffle
Clock out
Play / Stop
Direct access to modes (Pattern, Project, Live REC...)
MIDI INTERFACE

A MIDI Channel can be assigned to an Eloquencer Track, so the gate and CV outputs will stop listening to what is sequenced and start listening all note on/off messages coming from the chosen MIDI channel.

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

Depth: 38mm

HP : 8

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.

Features

Unipolar or Bipolar Operation
DC Coupled Analogue Signal Path

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: 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: An updated version of the excellent Batumi quad LFO, version II introduces performance updates plus compatibility with the new Poti II expander. Original Poti I breakout functions are now included in the Batumi II.

Supplier's Notes:
Xaoc Devices presents Batumi II - a greatly improved and enhanced new iteration of the modern day classic that is/was the original Batumi, preserving its layout and form factor. The premise remains the same: four LFO's with individual outputs for sine, assign and rectangle waves. The channels can operate independently or they can be linked - phase shifted, divided or multiplied (new mode alert) with regard to the first channel. Multiple major and minor improvements have been implemented, e.g. when synced to an external clock source, each channel's frequency slider selects a clock division for that channel's outputs.

Xaoc Devices have managed to incorporate the features of the original expander into Batumi II (sync mode switching and assign waveform selection) without changing the size of the module which opened up new possibilities for the new optional expander. The Poti II expander for Batumi II adds multi destination inputs for sine wavefolding, assign output waveform selection or rectangle pulse modulation with the destination set for each channel independently. Poti II also features frequency input attenuation as well as sine and assign output attenuation. All adjustments may be performed separately for each individual channel or for all channels simultaneously.

The Batumi II software has been rewritten from scratch to ensure best performance. The hardware has also been updated to allow for V/oct tracking and stable operation up to audio rates (more powerful CPU, precise, wideband converters, antialiased waveforms).

-4 LFO's
- redesigned from scratch - both the hardware and software
- new waveforms for the assign output (including random)
- new frequency multiplication mode
- all features of the Poti expander incorporated into the main module
- very wide frequency range well into audio rate
- 1V/oct tracking = so can be used as 4 VCO's
- in the Phase/Divide/Mult modes the random waves at the ASGN output follow the values available in the master/A channel
- 10HP
- +90/-50mA

Notes: Belgrad is an all-analogue voltage controlled filter module which - on par with our other modules - brings something new to the table. While it can be used as a traditional VCF for "academic" subtractive synthesis, we guarantee countless hours of exciting timbral explorations thanks to its unique character, flexibility, and features. The most prominent feature is that it offers a multitude of frequency responses with two resonant peaks.

- Eurorack synth compatible
- 14HP, skiff friendly
- Current draw: +45mA / -42mA
- Reverse power protection

Notes: Part of Xaoc's range of modular mixing tools, the Bohumin 1966 is a commander module for Ostrawa stereo mixer modules, adding a second stereo aux bus, voltage control and manual attenuators with clickless mutes

Supplier's notes:
Bohumin [bo'xumin] is an expander for Xoac Deives' Ostrawa full stereo mixer module. By connecting to Bohumin, Ostrawa gains a second full stereo AUX bus with voltage control over the amount of the effect on each channel. Bohumin features manual attenuators for stereo returns of both AUX A and AUX B, as well as four gate inputs for automated clickless muting of each stereo input channel. Please note that Bohumin is not compatible with Ostrawa's sister module Praga. Similarly, Praga's expander Hrad cannot be connected to Ostrawa. However it is possible to chain any combination of Ostrawas and Pragas, and each of them may have its corresponding expander attached.

Technical details

10hp, skiff friendly
Power drawn from Ostrawa: +50mA/-40mA

Notes: Part of Xaoc's Leibniz Binary Subsystem, the updated Drezno ADC/DAC module builds on the original with higher resolution converters, allowing you to use it for pitch quantisation.

Supplier's Notes:
Drezno II is an improved version of the original Drezno module. It is an essential member of the 8-bit Xaoc Devices Leibniz Binary Subsystem. The Leibniz subsystem is a family of modules that operate on 8 binary (two-state, on/off) signals. These signals are arranged as 8 bits of digital data and may represent analogue signals and voltages, or they may be whatever you want them to be (clocks, gates, rhythms, etc.).

Drezno features an ADC (analogue-to-digital-converter) and DAC (digital-to-analogue-converter), allowing it to act as an analog front-end of the system. In other words, Drezno allows one to convert analogue signals and CVs into digital numbers, as well as to obtain analogue signals back from some other digital numbers (or 8 binary signals). Between these two conversions there is a whole universe of digital shenanigans waiting to happen resulting in all kinds of signal transformations and modulations.

Both (ADC and DAC) sections of Drezno can work independently, or they can be linked. Input and output range of analogue signals may be adjusted using Gain and Offset sliders. Individual bit outputs (for the ADC) and inputs (DAC) allow for extensive cross-patching and the creation of complex waveforms and rhythms. A very fast clock (up to 2MHz) at which the conversions are performed may be replaced with any external clock (for each section separately).

Compared to its predecessor, Drezno II uses new converters of much higher resolution which results in much lower noise floor and higher accuracy. The lower bits are much more stable than before. It is easy now to use Drezno for quantizing pitch voltages with accurate results with 128 or 256 semitone steps. Potentiometer ranges are factory calibrated for precise chromatic scale. A new switch on the front panel allows the user to select the calibrated range of 10Vpp or 20Vpp, so that the lowest bit or the second bit correspond to 1 semitone.

Notes: Gera is a component of the Leibniz subsystem that allows masking individual bits of the digital data by the use of logical AND operation.

It features 8 individual gate inputs that affect the individual bits of data, as well as 8 illuminated tact switches for manual inverting of each control input. When connected to Drezno that is processing a waveform or voltage, masking of individual bits yields various forms of quantization. However, Gera can function on its own. The AND operation is a basic building block for sequence automation, chaos and rhythm generation, and various computer-like modular patches.

Bit processing logic in Gera is hardware based, hence there is virtually no latency, and the binary signals may change at extreme rates.

Main features:

Logical AND operation on Leibniz data
Masking of individual bits controlled manually and by gate signals
Visual indication by illuminated buttons
6HP
30 mm depth (including ribbon cable brackets)
- +12V: +45mA / -12V: 0mA / +5V: 0mA

Notes: Three-band isolator with stereo inputs and outputs, splitting the signal into highs, mids and lows then allowing you to control level and frequency via CV for some clever sound sculpting and modulation.

Supplier's Notes:
Katowice is a stereo variable-band isolator that allows the user to manipulate a selected range of frequencies. It is the first module in a series of upcoming Xaoc Devices products designed specifically for processing stereo signals.

Katowice splits the stereo input signal into three bands: low, middle, and high. While the knobs and CV inputs define the center frequency and bandwidth of the mid band, the low and high bands are automatically adjusted so that the sum of all three is a complete signal. All three bands are passed through high quality VCAs and their stereo outputs are available separately for further processing. A stereo mixdown signal is also available.

Katowice may be used as a crossover network, a parametric EQ, DJ-style kill filter, or other band-selective applications, including multiband compression and stereo enhancement.

Notes: Gorgeous stereo implementation of the classic frequency shifter sound, moving from tonal harmonics to atonal disharmony effortlessly. Separate outputs for down and up shifts, plus plenty of CV control.

Supplier's Notes:
Koszalin is a full stereo frequency shifter with two inputs and four outputs. If offers simultaneous exponential and linear through-zero control of the amount of frequency shift in 3 carefully scaled ranges (up to +/- 5kHz). Frequency shifting results in linear translation of signal spectrum producing all kinds of atonal sounds. It should not be confused with frequency scaling, also known as pitch shifting. Several stereo feedback topologies are offered with additional density control besides feedback depth, which results in spectacular stereo barberpole effects.

Through-zero modulation allows for using Koszalin's input as an FM operator. Koszalin is a digital module with a DSP behind an analog interface.

Main features:

full stereo frequency shifting
3 shift ranges: +/- 50Hz / 500Hz / 5kHz
exponential and linear through-zero inputs
internal feedback under voltage control.

Notes: Great value from Xaoc's pingable dual VCA, capable of creating organic, acoustic-style decay curves which replicate the dynamics of real-life instruments. Ideal for processing audio as well as CV.

Supplier's Notes:
Xaoc Devices Lublin is a high-quality dual VCA module with exponential CV inputs. On top of that, its two identical channels feature additional inputs for pinging. These inputs use an elaborate analogue circuit to model the dynamic behaviour of vactrols, allowing you to trigger a carefully crafted gain response that mimics the natural decay of plucked and struck acoustic instruments. Unlike lowpass gate modules though, Lublin reduces gain while retaining the full frequency bandwidth, so it is perfect for harmonically rich signals, like our Odessa additive VCO. The vactrol-like behaviour is just a starting point as the envelope may be varied within a wide range using a switch (natural, shortened and prolonged response) and a potentiometer, so you are not stuck with one decay characteristic. Therefore, you can use it not only to create bongos, but also for fat compressed kicks! The built-in gain control circuit (saturating CV instead of the audio signal) prevents distortion from excessive amplification. Lublin is DC-coupled, so you can use it to process CV as well as audio signals.

Notes: User-friendly mid/side processing module. Tweak the stereo image or split a stereo signal into mid and side elements then route out to other modules for further processing before summing back together. Powerful.

Supplier's Notes:
Minsk is a stereo image processor. It is a hybrid tool that combines digital and analog processing to facilitate advanced mid/side (M/S) manipulation of a stereo signal pair. It allows for separate treatment of the mid and side components, which affects the depth and width of the auditory scene. Minsk offers both manual and voltage control of the stereo width, as well as two dimension effects for enhancing the existing stereo image or creating a faux stereo image based on the stereo or mono input source. Minsk is especially handy during the preparation of a vinyl release or before a club concert, because it can eliminate out-of-phase low-end frequencies (high pass filter at 300Hz with the filter slope 12dB/oct, 50Hz with the filter slope 24dB/oct).

Notes: Additive synthesis oscillator based on the concept of building up harmonics from sine waves. A complex idea nicely executed for ease of use.

Suppliers notes:
Odessa implements the principle of additive synthesis controlled by a set of carefully tailored macro parameters to harness thousands of sinusoidal partials that altogether form the resulting sound.

The interface is kept simple and accessible, so you can easily build rich and full, great sounding timbres of very complex spectra, that can be either harmonic or inharmonic. Even though inharmonic spectra yield non-periodic waveforms, all partials are frequency related to the common fundamental controlled by a V/oct input. The series of harmonics can be squeezed or spread apart, tilt, and pruned by a comb-like frequency response, resulting in a variety of unearthy sounds. Animating the comb response yields radical effects similar to flanging and phasing. Additional, often sought after features are implemented: through-zero linear frequency modulation, and unison detune: up to 5 copies of the sound can be spread apart for a fat and dense cluster of voices.

There are nine parameters, each controlled by a dedicated knob, so the workflow is as smooth and immediate as possible. Furthermore, every parameter has a dedicated CV input, allowing live animation for organic audio effects. Odessa sports two main outputs for banks of harmonic partials that can be further scaled in frequency, as well as an additional output that can either spit out a square wave or a single sinusoid of the fundamental frequency. Interesting spatial effects, crazy modulation feedbacks as well as synchronisation is possible that way.

The hardware is based on a powerful FPGA chip offering massive parallel computing. The synthesized signal is devoid of aliasing through the entire audio range thanks to intrinsically bandlimited algorithm. A simplified spectral analyser helps you to keep a visual track of what is actually happening to the harmonics.

For even more control over Odessa, you can use the Leibniz subsystem (or just the Lipsk) that can be connected to a header at the back of the module.

Notes: Part of Xaoc's Leibniz subsystem, which processes signals and voltages by manipulating binary 8-bit numbers, the Poczdam allows switching between two data sources.

Supplier's Notes:
Poczdam is a binary data routing solution for the Xaoc Leibniz Subsystem. It facilitates manual and remote switching between two Leibniz data sources, modifying individual bits of the data stream, and re-clocking the data with its onboard voltage-controlled wideband oscillator or any external clock signal. Poczdam is particularly useful within complex Leibniz setups where the user needs to reconfigure the data flow between multiple modules. However, it can also be employed in small creative patches, e.g., for waveform splicing, disrupting rhythmic loops, or generating digital chaos.
To better understand the device and avoid common pitfalls, it is strongly advised to read through the entire user manual before use.

Drezno is the input/output front-end of the system, consisting of an analogue-to-digital converter (ADC) and a digital-to-analogue converter (DAC), that alone can be used for manipulating analogue signals and voltages based on their binary representation.

Lipsk is a binary logic processing expander module that can flip (invert) individual bits of the digital signal representation. There are more Leibniz Binary Subsystem elements coming, with specialized and advanced sets of features.

Jena is a digital module that may be used as a flexible waveshaper for CV and audio signals, a wavetable oscillator, a Walsh function generator, or a rhythm generator.

Erfurt is a bi-directional digital counter, frequency divider. It has multiple applications: the output of the counter may be used as a phase source driving a digital wavetable, connected to other Leibniz modules it may scan waveshapes in Jena, produce stepped voltages useful for making interesting glissandi with Drezno and any VCO, generate gate patterns animating the spectrum of Odessa harmonic banks, spawn pseudo-chaotic sequences when fed back to Lipsk, etc.

Notes: Part of Xaoc's Leibniz binary system, the Rostock is a digital delay line capable of processing triggers, audio, CV and video signals. Another useful module from the unique Leibniz series.

Supplier's Notes:
Rostock is a component of the Leibniz Binary Subsystem. It is a data pipeline, a FIFO (first in - first out) shift register, or a very short digital delay. The module operates similarly to a BBD delay or an ASR (analogue shift register), except that it is digital. It consists of a chain of memory cells that pass bits from one to another at each clock cycle. The delay length is variable from 1 to 64 stages (with optional looping and scrambling). It works by processing data in the Leibniz bus and must be connected to other Leibniz modules using data ribbon cables at the back. Rostock may process data sequences representing rhythms, control voltages, audio-rate signals, and even video signals because the bits can change at extreme rates (up to 2MHz). In addition, its memory may be digitally looped. Delaying and looping is a fundamental building block for sequence automation, pattern and chaos generation, and various cybernetic modular patches. Thus, Rostock is a multi-purpose open-ended device that invites creative thinking.

Notes: Samara is a "Swiss Army Knife" type of module, intended to serve the most common voltage and audio signal processing purposes such as attenuation, offsetting, mixing, inverting, and even basic waveshaping. Samara features four channels, each with two inputs and an attenuator, additional switchable offset generators, four voltage level and polarity indicators, two adders with switchable scale, and a precision four-channel processor that selects minimum and maximum voltage.

Notes: A super impressive offering from Xaoc, the Samarkanda is a quad delay module designed for hands-on, real-time performance. Dial in everything from loops to stereo delays, resonators, modulation effects and much more.

Supplier's Notes:
Xaoc Devices Samarkanda is a digital quad delay module with extensive patching capabilities and a lot of flexibility for signal mangling. It can be used as four entirely independent delays, a dual stereo delay, a complex/multi-tap or multi-channel delay, a quad/polyphonic resonator, dual chorus, dual flanger, reverb, looper (with sound on sound!), and granulator, or any combination of those. You can reverse the delayed signal, hold it, squeeze and stretch it beyond all recognition and still go back to the original piece of audio captured in the buffer! The internal lossless normalization (the signal doesn't leave the digital domain) combined with top-notch components (including 24-bit AKM converters and 32-bit internal processing) are responsible for high sound quality. Samarkanda has been conceived in the truly modular spirit. Not only can you control almost all its features remotely with CV/gates, but the external feedback path gives you the opportunity to process the delayed signal with other modules.

Samarkanda offers a wide range of delay times beginning at a mere 0.5ms and reaching up to 15 seconds per channel. That means that, by stacking its four channels, you can achieve up to one minute delay! There are two operating modes switchable individually for each channel. Analogue delivers pitch changes that resemble classic analogue tape and BBD delays. When you combine it with the looping Hold function, you can play Samarkanda with any 1V/octave CV source. By using the Sync function you can even loop single wave cycles. The Digital mode gives you a granular buffer-scrubbing effect (no pitch change) across the whole delay time range. You can seamlessly switch back and forth between modes without losing any information. You can use Samarkanda for multiple tasks at the same time - from four independent delay lines through any combination of channels processing the same signal up to a quad behemoth. You can also use the linking feature for ease of operation (the first channel in the chain acts as the main control source for the others).

As most settings operate on a per-channel basis, you can freely combine different features (such as analog/digital behaviour, delay time range, reverse and hold functions, etc.) in a configuration of your choosing. You can synchronize each of its channels separately to a different source, either via the Sync input, or by using the tap-tempo functionality (with multiplication and division galore). Should you ever get lost, the Purge button comes in handy when/if things start to spiral out of control!

Notes: Sarajewo is an analog delay module based on old school (but newly manufactured) BBD (Bucket Brigade Delay) chips. It features three delay taps, an external clock input with various tempo sync factors, and a wide range of settings controllable via CV. It is based on high quality components with maximum effort put towards the highest sound quality possible, while still preserving the charm of the BBD technology. The module offers a clean and warm analog sound with tons of character and a comfortable user interface with a tap tempo button, signal level indicators, sync and CV inputs, four signal outputs, and an adjustable feedback filter.

Notes: A big deal even by Xaoc's prolific and eclectic standards. Fully analogue VCO based on the none-more-old-school fonction d'onde formantique, implemented with extensive CV control. Transcendent waveforms indeed.

Supplier's Notes:
Sofia is a fully analogue voltage-controlled oscillator (VCO) based on an original waveforming principle. It features a modern, well-calibrated, temperature compensated triangle core and two elaborate waveshaping and modulating sections. The sound is a mixture of a warm, saturated base tone and two ripple components. Besides its main output, Sofia offers access to individual components of the sound plus a multitude of modulation inputs allowing for extensive self-patching and animation of the waveform. To better understand the device, it is strongly advised to read through the entire manual before using the module.

Sofia implements and extends the classic computer music method for synthesis of formant sounds called FOF (fonction d'onde formantique), which uses a combination of simple, time-domain components (decaying sinusoidal waves) to achieve desired spectral characteristics.

In Sofia, two of such ripple elements are added on top of a slightly saturated sinusoidal base tone. Each new cycle of the base tone spawns a new pair of ripple elements. The ripples' density and decay rate may be adjusted over a wide range. Additionally, the elements may be warped so that their density accelerates or decelerates within the cycle. Finally, their basic waveform may be switched from sine-like to square-like for additional richness.

Despite the seemingly divergent frequencies present in the signal, it remains strictly harmonic due to how all elements are waveshaped from the core tone and therefore phase coherent. Thus, Sofia is not a complex oscillator in the Buchla sense; however, it goes beyond the traditional set of primary waves and wavetables, hence the name.

Notes: Sopot is a compact utility module handy when the need arises to sum multiple stereo and mono sound sources (up to four signals for each section). It is a triple summing mixer featuring three signal adding sections with the middle one optionally fed to the top and bottom ones. The contribution of the middle section is switchable between 0%, 50%, and 100%. Each of the summing sections is built with high quality audio opamps and features a soft clipping circuit for nice saturation. Gain can be optionally reduced to -12dB in order to allow summing of hot signals.

Notes: Another cracker from Xaoc, the Timiszoara is a take on digital multi-effects with stereo in and out, an intuitive interface and CV control of effect parameters. Big power with 176 factory programs.

Supplier's Notes:
Timiszoara is a stereo, Eurorack compatible, voltage-controlled multi-effect signal processor based on the popular Spin Semiconductor FV-1 DSP chip. It features a full stereo signal path with two adjustable audio inputs, two outputs, and a stereo voltage-controlled wet/dry mixer. In addition, there is a microSD memory card slot on the front panel that allows for loading factory and custom effects without any restrictions or copyright protection, which means you can use many effects available on the Internet and even create your own.

Effect programs are organized in banks of 8 and can be selected using a rotary encoder, as well as CV and trigger signals. Timiszoara features a crisp OLED screen that displays the program parameters and its name. It also facilitates navigating the list of banks. Up to three parameters per effect can be controlled from the front panel with illuminated slider potentiometers and dedicated CV inputs.

Xaoc Devices have prepared quite a few banks of algorithms (176 in total) that cover most effects needs: delays, reverbs, filters, modulation effects (such as choruses and flangers), pitch shifters, and, of course, shimmers (no multi-effects unit would be complete without its share of those). However, Xaoc Devices wanted to ensure that users had access to some more adventurous programs, so some special banks have been created to allow you to take a walk on the wild side.

Notes: A seriously versatile filter here, much more than meets the eye. Stereo, state-variable, multi-mode design gives you huge control over frequency response and stereo image.

Supplier's Notes:
Zagrzeb is a stereo multimode 4-pole (24dB/oct) state variable voltage-controlled filter (SV VCF). It offers five distinct frequency responses, three of which are available simultaneously. Spread control allows for animation of the stereo image by moving the left and right filter cutoff frequencies in opposite directions. Zagrzeb is designed to sound smooth and clean unless it is overdriven with a hot signal- however, it does not lack character! We believe it will be appreciated by fans of old Japanese synthesizers, but bear in mind that Zagrzeb is not a clone of any existing design. The four-pole state variable structure is a new development and offers unique sonic characteristics. While Zagrzeb is designed for filtering stereo signals (e.g. samples or stereo oscillators like Xaoc Devices Odessa), it can easily handle mono signals and is capable of creating a faux stereo pair thanks to a special phase shifting network at the input.

Notes: The Dual VCA is a 2hp 2 channel Analog VCA and Mixer Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It is a DC coupled OTA(LM13700) Dual Linear VCA based on the same fabled design of the VnIcursal VCA. The 2 VCAs are summed together so it can be used as a voltage controlled mixer at the "SUM OUT" or all 3 outs can be used separately and simultaneously. 5 volts into the CV in will provide unity gain, anything above 5 volts can clip the input.

Notes: The Entropy Expander is a 3hp Analog Random Voltage Generator that expands upon the features of the Entropy Euroack Module. Available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

The Entropy+Expander packs together some of the most random voltage options in 6hp. It provides a controllable "Glide"(slew) out for the S/T\H, a comparator with a controllable rate("Thrsh") of random gates("Rand Gate") out with an input to compare other waveforms(Comp In, inserting a cable into here breaks the white noise normalization), and high pass filtered white noise resulting in approximate "Blue noise" (+3db/octave) and "Violet noise"(+6db/octave) outs.

The unique part of the circuit is a voltage controlled A/B switch thats normalled to the "Rand Gate" out that's switching between the S/T\H out(left Blue led window)and Infra out(right Red led window), the Glide control also effects the S/T\H coming out of the switch so you can get really random results from the "Entropy Out." Inserting a cable into "Switch CV In" breaks the random gate normalization and lets you toggle between A/B(left S/T\H out and right Infra out, indicated by the led windows) with your own gate or trigger.

There is a jumper on the pcb to select if you want glide on the s/t\h at, Entropy out, or un-slewed operation. There is also a trimmer for setting the amplitude of the incoming signal at "Comp In" which sets the frequency range of random gates. This may have to be adjusted depending on your Entropy version.

The random gate range can also be set up more as a noise oscillator by turning the pcb trim(clockwise) up or it can be set so random gates are extremely slow(trim counter clockwise) with minutes between random gates.

Notes: The Triple Cap Chaos(C^3 Chaos) is a 2hp analog, chaos based, noise oscillator, pseudo ring modulator/harmonics generator, and audio mangler Eurorack module available as a DIY Eurorack kit, PCB and Panel, or built.

It is a unique module, like the Diode Chaos, because it has never existed as a musical instrument until now. There is also no other module to my knowledge that can do exactly what the Triple Cap can do. The circuit(with several modifications) is based on the paper "Simple Autonomous Chaotic Circuits" by J.C. Sprott and Jessica R. Piper. As opposed to the Diode Chaos that generates control voltage this module focuses on the audio rate.

The "Emanate" potentiometer controls the coarser overall spectrum of the chaos, from lots of activity counter clock wise up to less chaos and more of a steady oscillation. The "Width, CV ATT" potentiometer can be thought of as more of a fine control for the chaos/oscillator. When something is inserted into the "CV" in the voltage normalization from the width knob is broken and the potentiometer now acts as an attenuator for the incoming cv. The Triple Cap is not a traditional volt per octave exponential VCO, and has a sort of narrow frequency range to exploit the chaotic behavior.

It expects a +5v to -5v max signal in to modulate the chaos. The "IN" jack is an A.C. coupled input for audio in, although cv and audio can work for both the "CV" in jack and "IN." The "IN" will interfere and interact with the onboard chaotic oscillator depending on the frequency of the input, which may take some experimentation. It can create ring mod ish sounds, to added harmonics, to almost bit crushed sounds depending on the "X" or "Y" output. The "X" output is a more windy noisy sinusoidal based output and the "Y" output is more squared off and aggressive, harsher sounding output.

Some quirks about the Triple Cap: The "X" output can offset negatively or positively a little bit depending on the pot settings, but both outputs tend to stay around 10vpp. With the "Emanate" and "Width" pots all the way up the typical frequency will be around 150hz although some will reach 200hz at this setting. With the "Emanate" pot full counter clock wise "Width" pot full clock wise the frequency will be around 250hz. It is possible to send signals into the triple cap that can bring it out of the desired range causing the oscillation to cut out.

The Triple Cap has a double sided panel. meaning one side has the classic graphics and the other is Soulless with less graphics.
