Quadruple Low Frequency Oscillator (LFO) synth module in Eurorack format - 10HP wide
Notes: Batumi is a fully voltage controlled, quadruple digital LFO module with a slew of interesting and user-customizable features. Each oscillator can be used independently or in one of 3 synchronized modes: quadrature, phase and divide. For each oscillator, there are sine, square and assignable (saw, ramp, triangle and trapezoid) waveform otputs available. Voltage control is possible for each oscillator's frequency, reset, and external sync ("tap tempo"). The total frequency range spans from 28 hours in voltage controlled divide mode, up to 500 Hz.
All-analogue voltage controlled filter module - Eurorack compatible
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.

Utility synth module in Eurorack format - 6HP wide
Notes: Bytom is a simple - yet very useful - utility module that allows you to combine various trigger/gate signal sources to obtain interesting rhythmic events, useful for sequencing, modulation and patch automation purposes. It can also be used for summing control voltages of a positive polarity. The module consists of three independent sections. Each one can process up to four signals fed to its inputs. All three sections can be normalled into one 12-signal combination via the manual switches. Either the upper or lower section can be combined with the middle section to form an 8-signal combination. Summed signals of two or three sections will appear on the middle section's output socket. The individual outs on upper and lower units remain active even when combined with the middle section.

Analog signal processing module with simultaneous four & six-stage outputs - Eurorack compatible
Notes: Kamieniec is an analog signal processing module directly inspired by a range of classic phaser effect units from 1970s that helped to define entire musical genres. Most of these classic devices contained a fairly small number of phase shifting stages, but made up for that lack with tons of character! However, what was initially intended for guitars is not necessarily sufficient for synthesizers. Therefore, the intention is to preserve the classic sound as it's transported it to a new tonal space while prioritizing flexible modular usability.
Just like many of the famous OTA-based phasers of the 1970s, Kamieniec sports four tuneable stages. However, there are two additional fixed stages included so as to increase the number of notches, and ultimately offer two versions of the mixed signal (that may be used as a stereo pair) at the two outputs of the unit. While the general topology is similar to a certain very classic phaser pedal, the circuitry has been redesigned with modern components and low noise op-amps to bring down the noise floor, improve the bandwidth, and offer a wider range of tuning. The feedback control can be set extremely deep, which results in a very high resonance that is capable of self-oscillation. This produces a unique sound otherwise unreachable for typical phasers, which can vary from subtle and creamy to utterly brutal and grinding. On top of that we've included switchable feedback paths, individual stage group outputs, CV inputs, built-in LFO, and daisy chaining ability to provide a comprehensive integration with a modular synthesizer system.
Unlike any other phaser module, multiple Kamieniec units can be chained together to achieve a more radical response with many notches. The general idea of chaining is to pass along the phase shifted signal to subsequent units before it is mixed with the original version in the last unit of the chain. This approach has a very different effect than plain cascading (connecting multiple phaser units in series), because a long chain of allpass sections yields a dense and uniform pattern of multiple notches, exactly like in a long phaser.

Breakout expander for the Batumi quadruple LFO module
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.
Voltage controlled four channel stereo mixer module
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.
Multi-tool synth module for audio signals & control voltages
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: 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: 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.
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.

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: 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.
