Notes: The Zorx 1U CV Bus is an 84 HP 4 - 1 x 4 or 2 - 1 X 8 buffered mult with attenuation/attenuverting on each output for use with audio and CV signals.

There are four channels, each with four dedicated outputs, separated into groups of four. 4X4X4. Input a signal into any channel and use that channel's outputs to spread the input signal throughout your rig. With outputs spread out in this manner, it inspires creative modulation and patching.

Channel 1's input is normalled into Channel 2's input for use as a 1x8 mult. Likewise, Channel 3's input is normalled into Channel 4's input for use as a 1x8 mult. When nothing is patched into Channels 1 and 3,+5V is fed into each input for use as an offset throughout their respective channels with a peak to peak voltage of -5V to +5V available at each output.

Each output has attenuator/attenuverter potentiometer control. Center position is off - no signal at the output. These outputs are buffered so that with one input you can have four separate and different variations of the input signal at each of its corresponding outputs.

See-thru colour coded LED indicators denote which channel an output belongs to for easy maneuvering during live performance and in dimly lit situations, and there are also numbered dots below each potentiometer that denote that as well.

The Zorx 1U CV Bus uses +12V 90 mA and -12V 90mA, and doesn't need a +5V rail to operate. It has a depth of 27mm. The faceplate is black matte with copper.

The 20 HP Zorx SILENCER 1U CV BUS Expander is also available to buddy up with the 1U CV Bus.

The Zorx 1U SILENCER is a clickless 20 HP 4 channel performance silencing module that lets you manually switch each channel on and off, thereby muting it, with latching or momentarily capabilities. There is also a MIX OUT that sums all of the SILENCER's outputs into a single mono output. A connector cable [included] can be connected from the rear of the Zorx 1U CV Bus to the rear of the SILENCER which will take the last four outputs of the Zorx 1U CV Bus and duplicate them, normalling them to the corresponding inputs of the SILENCER. This normalization can be overridden by patching an input into each channel so that the SILENCER can act on its own or in tandem with the Zorx 1U CV Bus, or a combination of the two. Illuminated numbered dots correspond to the 4 channels of the 1U CV Bus for easy recognition.

The SILENCER can be used as a 4-channel on/off/(on) performance switch, a 4-channel audio or CV mixer, or a combination of the two while having control of which channels you want in the final mix.

The SILENCER consumes +12V 40mA and -12V 40mA and has a depth of 40mm.

Notes: A whopping six channels of VCA action in just 8hp of rack space. DC-coupled linear VCAs based on the LM13700 OTA. Normalled to act as a summing mixer. Very nice.

Supplier's Notes:
The VnIcursal VCA is an 8hp 6 Channel VCA Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It the smallest, most compact Voltage Controlled Amplifier in the Eurorack market. It provides 6 OTA(LM13700)-based DC Coupled Linear VCAs for Audio or CV. The 6 VCAs are summed together so it can be used as a voltage controlled mixer. Each VCA is normalled to the sum so they can be removed from the mix and used on their own. The potentiometers control the amount of gain, and when a voltage is inserted into the CV in the potentiometers act as attenuators. With a control voltage of 5 volts the VCA will be at unity gain, anything above that can clip the input. LED brightness with or without CV in provides constant feedback of each channels amount of gain.

The VnIcursal is not a perfect scientifically spec'd VCA. Analog VCAs can only close so much, or be so silent. In certain situations based on power supplies and gain stages the VCA can experience some bleed or noise mainly at the sum out as all channels are passively summed then buffered.

Notes: VC F3DB stands for Voltage Controlled Fixed Filter Feedback Distortion Bank. The simplest description is it's a 6 band voltage controlled fixed filter bank. But with the additions of so much gain, clipping, feedback, and self-oscillation it becomes a very flexible and unique sound sculpting tool capable of; graphic equalization over 6 octaves, multi-band distortion, spectral processing, crude vocoding, self modulation, and even as an instrument on its own. With no input it can be used as a pseudo chaotic "harmonic" feedback oscillator.

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.

Notes: The SVF is a 4hp 2 pole 12dB State Variable Filter Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It provides Low Pass, Band Pass, and High Pass outs inspired by WASP and Thomas Henry filter topologies. The filter has 2 audio inputs, but channel 2 is jumper selectable between standard audio in or Ping-able operation. The 2019 revision also adds improved cutoff and resonance response and attenuversion through the ACV IN using the above pot. CV IN provides another unattenuated voltage input to modulate the frequency.

At the CV in, +10v will open the filter completely if the cutoff pot is CCW(counter clockwise). With the cutoff knob at noon the filter can be opened with +5v or closed with -5v. CV input at the ACV in is dependent on the CV attenuverter knob.

There are also several jumper selectable modes for max resonance, self oscillation or no oscillation based on the setting of the resonance pot. According to the jumper configuration, the filter is capable of clinical and clean, to juicy and drippy, to low pass gate sounding plonks, to screaming chaotic resonance. When set to self oscillation mode, the filter can produce a sine like wave with no input and a trapezoid like wave in the max resonance jumper setting. In max resonance mode, the filter output can exceed 10Vpp. On the newest version, there is a trimmer on the top pcb to set the lowest cutoff frequency.

The new black and white pcb/panel is reversible meaning, one side is classic (first picture) and the other side is soulless (second picture).

Notes: The Skew-Fade LFO is a 3hp Analog Low Frequency Oscillator Eurorack Module capable of a plethora of waveforms, available as a DIY Eurorack Kit, PCB and Panel, or Built.

It has three rate settings ranging from 3 minutes and 30 seconds a cycle up to audio range at 20 hz. Triangle waves can be skewed between ramps and saws, and square waves pulse width can be adjusted from inverted triggers to triggers. The LFO's unique feature is voltage controlled cross fading through the ("Fade C.V." in) between square/shark tooth\sine waveforms provided at the "Fade Out." All outs are also influenced by the skew knob resulting in many complicated and asymmetrical possibilities at the "Fade Out." It can even be self patched(ie triangle or square into fade cv) for an extended pallet of waveforms. The "Fade C.V." in expects a bipolar voltage 10vpp to fade from square to sine with the fade pot at noon position. Bicolor led provides constant display of positive and negative voltage crossings.

Notes: The Push VCA is a 2hp 2 Channel DC Coupled Mute Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It features 2 independent unity gain DC coupled VCAs with led push button mutes. A mix of both channels is available at the sum, but all outputs are available simultaneously. The newest version has normalizations to +5v, so with nothing plugged into the ins voltage can be toggled on and off at the outputs and up to 10 volts can be output at the sum. At checkout specify if you want latching or momentary push buttons. led button color may vary between red and yellow. but it will always be 2 of the same color.

Notes: Minimix is a Simple 2hp 3 Channel Unity Gain Audio or Control Voltage Mixer Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

Version 2 adds jumper selectable AC or DC coupling and linear or logarithmic operation for each channel. The newly revised MiniMix is now all through hole and aimed more to the beginner solderer. There is also a trimmer on the PCB to increase the master gain up to 2 or more for all 3 channels.

The module ships with a black and white reversible pcb panel.

Notes: MiniAtt is a 2hp Dual Passive Attenuator, Offset Generator, Mixer, and Mute Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

The newest 666 version can be powered and will provide Offset of 0-5V with nothing plugged into the "IN" for each channel controlled by each respective Potentiometer. The "Sum Out" will also be able to send out 0-10v~ volts depending on the setting of each Potentiometer. Both channels are normalled to the sum, so inserting a signal into an "IN" will remove it from the "Sum Out. There will be signal loss at the sum out, because the module is passive. Great for cv or audio although the module ships with linear pots.

Can be used Passively or Powered.

Notes: The MinEq is a 2hp simple 3 Band Equalizer Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It provides boost or cut control over the Low, Mid and High frequency bands of an audio input. The circuit is capable of up to 20vpp~ of boost(with a 10vpp signal) and attenuation down to 1-2vpp depending on the input. The frequency bands are centered near 50Hz(Low), 1kHz(Mid), and 10kHz(High). The circuit is AC coupled and will invert the input. With all the potentiometers at noon, the MinEq passes the signal relatively unaltered. The only SMD component is the IC.

Notes: The Foldiplier is a 4hp odd/even harmonics generator with 2 different oscillating feedback paths. The folding core of the design originates from the odd harmonics (middle)section of the Serge Wave Multiplier. But the Foldiplier adds voltage control over the symmetry and offset as well as a switch for feedback, jumper selectable between, a transistor based oscillating fuzz inspired by the Hemmo Bazz Fuss with a lot more low harmonic content and a passive oscillating half wave rectification circuit with more high harmonic content. When these feedback oscillations mix with an incoming waveform some unpredictable and unique nonlinear timbres can be achieved. The module can also be used as a no-input experimental oscillator with the feedback switch engaged. All diodes in the module are silicon.

The Fold knob controls the amount of times the waveform is folded in on its self (indicated by the red led window below the knob). The C.V. knob below is an attenuator for incoming control voltage corresponding to the Fold jack(indicated by the red led window above the jack, it only responds to positive voltage). So, the Fold knob acts like an initial amount of folding depending on its position. For example, with the Fold knob fully clockwise you can get even more folds with a control voltage in at the Fold jack. The Offset knob controls how much positive DC voltage(0 to 5v, clockwise) or negative(0 to -5v counter clockwise) DC voltage(indicated by the led window above the Offset jack, red for positive, yellow for negative) injected into the waveform via the Symmetry knob. With the Offset knob position at noon(0v) there will little effect from the Symmetry knob. The Offset jack is expecting +5v to -5v with knob position at noon to scan through the positive and negative voltage. The Symmetry knob controls the amount of negative or positive offset voltage(dependent on the Offset knob) mixed with the waveform(indicated by the yellow led window above the Symmetry jack). If positive voltage is mixed with incoming waveform more folds will occur on the positive troughs of the waveform, likewise, when negative voltage is introduced more folds happen on the negative troughs. This part of the circuit can also be broken down by thinking of the Offset as a voltage controlled crossfader swinging between positive and negative voltages into a VCA controlled by the Symmetry knob and jack. When a voltage is present at the Symmetry jack the Symmetry knob becomes an attenuator. The Symmetry jack only responds to positive voltage.

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: Entropy is a 3hp analog random voltage and noise generator Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built.

It features sample/track and hold normalled to white noise with a toggle switch for selecting sample (switch right position) or track (switch left position) and hold function. There is also a PCB trimmer(at the top of the motherboard) to adjust the spread(gain) of random voltages out from "scalar" (low gain, counter clock wise) to large interval jumping(high gain, clock wise). All analog white, pink, and brown (red) noise 10vpp~(dependent on lower PCB trim). Smooth (infra red) random cv out at 10vpp with 2 range settings from wiggly with (more events, switch in left position) to almost random rise and fall envelope behavior (less events, switch in right position). White noise pcb trimmer sets the amplitude of the noise which in turn influences the rate of the infra out. LED solder mask windows indicate positive(red) and negative(blue) voltage crossings.

Notes: The Dual VCO is a 4hp Dual Voltage Controlled Analog Oscillator Eurorack Module available as a DIY Eurorack Kit, PCB and Panel, or Built.

Each VCO has square, triangle, and sine wave out, coarse and fine tuning controls, a control voltage input, and a switch for selecting exponential or linear cv in. When a control voltage is inserted, the fine tune control becomes an attenuator for the incoming voltage. In exponential mode, when the attenuator is fully clockwise, the VCO will track around 5 volts per octave.

There are a couple quirks to these 8038 VCOs:

Below 300Hz the waveform symmetry is slightly off. triangle waves get a little uneven in the lfo range, the sine is not completely perfect to begin with the bottom trough and in the lfo range it slopes slightly, and the square turns more trapezoidal above 1khz(see scope shots) Also it doesn't track 1 volt per octave perfectly. usually the 1st and 3rd octave will be a couple cents off.

Other than those idiosyncrasies, it is a powerful, stable dual oscillator in a small footprint with no cross talk between oscillators. It's great for: drones and beating sine or triangle waves, cross modulating itself for interesting clocks/LFOs, creating complex waveforms/timbres through lin/exp frequency modulation.

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: Diode Chaos is a 3hp analog chaotic low frequency voltage generator Eurorack Module available as Eurorack DIY Kit, PCB and Panel, or Built Module.

It is a unique module because it has never existed as an electronic music instrument until now. The module is based on a circuit from a paper called "A simple chaotic circuit with a light-emitting diode" written by Volos, Wang, Jafari, and Kapitaniak.

Diode Chaos produces 3 phases of interrelated morphing voltages including a chaotic trigger out. The range is 20-30 seconds a cycle up to audio rate, although only the X out and TRIG out go up to audio rate. The frequency is controlled by the RATE knob. Each output exhibits different behavior at different rate settings. X,Y, and Z outs like to stay in the 4vpp range although at different RATE settings the outs can reach 10vpp. The TRIG out chaotically releases 0-10v triggers although sometimes it will spit out smaller voltage peaks.

LED soldermask windows provide constant display of positive and negative voltage crossings.

Differences between chaos and random(some quoted and summarized material from Ian Fritz's site):

Chaos is "highly irregular, but still contained within a finite region (the "strange attractor")"

Chaos occurs in 3 dimensions.

Chaos needs a non-linear element (with Diode Chaos the nonlinear element is a red LED, and the chaos is directly visible and useable at the TRIG out).

Notes: The Attenumixer is a 4hp 3 channel Passive Attenuator and Mixer Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

Each channel is normalled to the sum(VI) so it can be used as a 2 channel mixer and 1 channel attenuator, or a 3 channel mixer, or as 3 separate attenuators. Normalization to the sum is broken by inserting a jack into the outs of channels I-III. The Attenumixer works well with both cv and audio, although the potentiometers have a linear response. Since the module is passive there will be signal loss at the sum out.

Notes: Updated expander module for the Moskwa II sequencer. The Ostankino adds additional connectivity to the Moskwa II, allowing CV control of most parameters, plus extra outputs.

Supplier's Notes:
Ostankino II expander adds CV inputs for many Moskwa II functions, as well as a transpose input, clock out and individual gate/bit outputs for each step.

Notes: ***B-STOCK: Box opened, but product is in excellent condition and in perfect working order***


Updated version of Xaoc's Moskwa sequencer module includes customisable gate/trigger sections, independent randomisation sections, built-in quantiser, slew limiter and preset storage.

Supplier's Notes:
XAOC Devices Moskwa II - compact feature-packed sequencer with preset memory and trigger patterns.

Designed with live performance in mind, Moskwa II takes inspiration from vintage analog sequencers and greatly expands on their functionality surpassing our original Moskwa rotosequencer, while retaining the same size, basic panel structure, and operation principles.

At the core of the module is an 8-step CV sequencer and a parallel 8-step gate/trigger sequencer. But there's more, much more. Besides these basic functions, Moskwa II offers more unique, advanced features like eight independent programmable gate/trigger pattern generators (one for each step of the sequence). You can treat them like sequencers within the sequencer offering another eight microsteps for each main sequence step. This allows for programming complex gate/trigger rhythmic patterns (e.g. step repeat, additional pauses, microshifting or swing effect).

Moskwa II features two independent randomization sections that give the user advanced control over the optional chaotic/random change of various sequence parameters (e.g. step order, slew and trigger probability and more). A programmable custom trigger sequence can be up to 256 steps long! Topping it all off, Moskwa II can store eight presets to be loaded at any time. All these functions allow Moskwa II to generate sequences much longer and much more complex than those produced by traditional 8-step sequencers.

Compared to the first Moskwa, Xaoc have also added a transport button for manual starting/stopping of the sequence, range control for CV output, and a flexible quantizer. Two Moskwa II units can be joined for chained operation doubling the number of available steps and preset slots. Ostankino II expander adds CV inputs for many Moskwa II functions, as well as a transpose input, clock out and individual gate/bit outputs for each step.

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: Zadar is a powerful, four-channel envelope, modulation, and transient generator, in a compact yet very complete, feature-rich package. It is capable of synthesising a vast palette of envelope shapes starting from hundreds of shapes stored in the memory. These starting shapes are not mere wavetables, but flexible vectors that can be stretched (from a fraction of a millisecond to half an hour), flipped, warped, distorted, delayed, shuffled, repeated, and amplitude modulated in real time. A set of freely assignable CV inputs allows for external control of most parameters. Each channel can work independently or combined with other channels within one of the chaining and looping algorithms.

Operating Zadar is quick and immediate, thanks to its accessible interface and crisp OLED display. The main screen displays all parameters together with the currently selected shape. Entering the simple 3-page menu is needed only for advanced settings.

Notes: Warna is a very useful utility module that helps you to manage control voltages in the system. Crammed in just 6 hp, there are five normalled sections: two buffered mults, two inverters, and a summing mixer. Each multiple routes the input signal to separated outputs without loss in voltage. Warna is designed for unity gain - if you apply a specific voltage to any input, it remains the same on the respective outputs. Inverters are hardwired to mults and invert the polarity of the signal applied to them. Both mults are also normalled to the mixer section via inputs. Patching anything to these inputs breaks the normalization.

The top and the bottom section both are buffered 1-in-4 multiples. The input can be inverted with a switch, i.e. its polarity will be changed by 180 degrees. Four inverted copies are then available at the outputs, meaning you can use these two sections as inverter. Bi-polar LEDs display whether the signal is positive or negative: yellow = negative, red = positive. The centre section is a four-input summing stage with amplification factor 1, a so-called unity-gain mixer. The multiples are normalized to the mixer which can be deactivated by patching.

Notes: Tirana is a super-compact step sequencer and modulation source, serving as the utility module for supporting other sequencing devices, but due to a suite of smart features, the module shines on its own terms. Tirana sports unipolar and bipolar voltages, mutable step triggering, transposition, and direction change controlled externally via CV. The step repeat function and virtually infinite expandability make it even more powerful.

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.

Tallin is a dual voltage controlled amplifier (VCA) with overdrive, offering some unusual control features and a range of attractive tonal characteristics. Each of the two identical channels offers two simultaneously available inputs for voltage control over signal attenuation or gain, with linear and exponential response to CV. Volume control knobs offer manual gain settings ranging from fully closed (-80dB) up to +18dB. A colour LED indicator displays output signal levels. A soft-clip circuit avoids harsh clipping distortion, while a switchable overdrive circuit offers two carefully crafted distortion responses, simulating the sound of classic tube amplifiers.

Since both CV inputs are simultaneously active, they can be jointly exploited within patches featuring more complex volume control that otherwise would require using two traditional VCAs in series. As the signal path is DC-coupled, Tallin can also be used for handling the control voltages.

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: Sewastopol is a multifunction Eurorack module designed for easy interfacing of external gear to your modular environment. It can export line and professional level audio, import audio from instruments and electroacoustic transducers, and analyse the incoming audio to generate voltages and triggers to control your modular system.

This is a second, vastly improved revision to the original 2014 Sewastopol, featuring a completely redesigned preamplifier circuit, better ergonomics and various other improvements.

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: 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: 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: The module is built around high quality VCA chips from THAT Corp, as well as low noise opamps. It offers clickless muting and equal loudness panning. The distinct feature is that voltage control is dynamically compressed should it yield clipping when pushed too hard. Also, in both modes the attenuators offer full closing of the corresponding channel, regardless of being controlled by the CV, or not. The VCAs fully open (0dB gain) at CV=8V in Env mode and CV=5V in LFO mode. All the input and output signal levels are Eurorack levels.

Multiple Praga units can be chained thanks to dedicated headers on the back. The mixed stereo sum of each unit in the chain is added to the mixing bus of all units downstream.

A dedicated Hrad expander will offer master volume control, gate inputs for channels muting/unmuting, headphone amplifier, and voltage control over aux sends.

Notes: Poti II expander notable features:

- per-channel input and output attenuation for the SINE and ASSGN outputs
- per-channel shape modulation with switchable destination (wave folding, shape switching, PWM)
- stores settings during a power cycle
- LED indication of the discrepancy between the stored setting and current pot position
- 4HP
- +10/-0mA from Batumi II

Notes: Poti is a simple but very useful breakout expander for the Batumi quadruple LFO module by Xaoc Devices. Its panel provides an immediate access to the Batumi functions originally selected by the cluster of jumpers on the back of the module: Reset/Sync mode option and selection of the assignable waveform.

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.

Very nicely designed mixer module. Four-channel stereo design with CV control of balance and volume, aux sends and extensive chaining options, including the optional Bohumin expander module.

Supplier's Notes:
Ostrawa is a full stereo four-channel voltage controlled mixer featuring a stereo mixing bus, one stereo auxiliary send per channel (switchable between pre and post VCA) with stereo returns, clickless muting, individual level meters, and a super-clean and DC-coupled signal path designed with high-quality VCA and opamp chips.

Xaoc Devices have carefully crafted Ostrawa's voltage control response to achieve what we believe to be the optimal user experience found in a Eurorack mixer. The design features an elaborate control circuit that combines the internal voltages generated by the panel potentiometers with external CV over volume and stereo balance. The result is a natural attenuator response that constrains VCA gain to a usable range while minimizing distortion.

Ostrawa is a sister module to Xaoc devices Praga. It features a very similar response characteristics and similar layout of controls with some functional differences resulting from stereo inputs and limited panel space. Multiple Ostrawa and Praga units may be chained for a custom configurable mixing system. An expander called Bohumin is also available.

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: Updated version of Xaoc's Moskwa sequencer module includes customisable gate/trigger sections, independent randomisation sections, built-in quantiser, slew limiter and preset storage.

Supplier's Notes:
XAOC Devices Moskwa II - compact feature-packed sequencer with preset memory and trigger patterns.

Designed with live performance in mind, Moskwa II takes inspiration from vintage analog sequencers and greatly expands on their functionality surpassing our original Moskwa rotosequencer, while retaining the same size, basic panel structure, and operation principles.

At the core of the module is an 8-step CV sequencer and a parallel 8-step gate/trigger sequencer. But there's more, much more. Besides these basic functions, Moskwa II offers more unique, advanced features like eight independent programmable gate/trigger pattern generators (one for each step of the sequence). You can treat them like sequencers within the sequencer offering another eight microsteps for each main sequence step. This allows for programming complex gate/trigger rhythmic patterns (e.g. step repeat, additional pauses, microshifting or swing effect).

Moskwa II features two independent randomization sections that give the user advanced control over the optional chaotic/random change of various sequence parameters (e.g. step order, slew and trigger probability and more). A programmable custom trigger sequence can be up to 256 steps long! Topping it all off, Moskwa II can store eight presets to be loaded at any time. All these functions allow Moskwa II to generate sequences much longer and much more complex than those produced by traditional 8-step sequencers.

Compared to the first Moskwa, Xaoc have also added a transport button for manual starting/stopping of the sequence, range control for CV output, and a flexible quantizer. Two Moskwa II units can be joined for chained operation doubling the number of available steps and preset slots. Ostankino II expander adds CV inputs for many Moskwa II functions, as well as a transpose input, clock out and individual gate/bit outputs for each step.

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: Lipsk facilitates the inversion of the individual bits produced by Drezno (or any other module connected to its input header at the back), and delivers the resulting code to its output header. Bit inversion can be manually controlled by pressing any of combination of its eight illuminated buttons, or it can be automated by patching gate signals into its gate input sockets. An active (5V) gate flips the state of the respective bit. If the button is active (bit already flipped), then the gate flips the bit again yielding double inversion (no inversion). The corresponding LEDs show the combined effect of both manual and gate actions. The bit processing logic is hardware-based, so there is virtually no latency, allowing the binary signals to be manipulated at extreme rates.
