Notes: On the surface, Xaoc Devices Berlin is a simple compact VCO offering square and saw waves with hard sync, FM input and octave switching. The most interesting part lies behind the panel and that is the Leibniz Binary Subsystem interface, namely LBZ out and LBZ in. The front panel LBZ LINK button and its corresponding gate input switch between the default saw wave and a signal that has been passed through any Leibniz module (or a combination of Leibniz modules) connected to Berlin. Add Xaoc Devices Jena for wave processing and the output is no longer a simple saw wave - you now have a vintage-style wavetable oscillator with a penchant for the experimental due to its open, hackable nature.

Berlin operates in a way similar to the classic PPG Wave and Fairlight CMI synths and employs a variable sample rate of an extremely wide-range internal clock. As the sample rate changes with the oscillator frequency, Berlin's internal square and saw waves exhibit no aliasing effect. The whole frequency range spans from 30 seconds in LFO mode up to 250 kHz (!) with the clock reaching an astounding 20 MHz. Add to that voltage control over all parameters and the result is a highly versatile module capable of creating a significantly diverse palette of unusual waveforms. To better understand the device and avoid common pitfalls, it is strongly advised that you read through the entire manual before using the module.

Connectivity:

Berlin connects to all modules compatible with the Leibniz Binary Subsystem: Drezno II, Lipsk, Gera, Jena, Erfurt, Poczdam, Rostock, Ostankino II, and Odessa.

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: Gross, gritty, and dark industrial-strength voice on a swappable oscillator platform. Pangolin approved.

Manis Iteritas Alia is a voice based on the architecture of Basimilus. It was designed to be grittier and more aggressive by using only sawtooth waves that are manipulated, modulated, and distorted through a rethought interface. Manis Iteritas Alia is fantastic for leads, basslines, drums, darkness, detuned swarminess, or pure mayhem. Plus, MIA's dedicated envelope output is a great modulation source for the rest of your patch.

MIA is available on Noise Engineering's 10HP Alia oscillator platform. Buy an Alia module and use the included USB cable to connect to the Noise Engineering Customer Portal to check out any other Alia firmware, free of charge, any time.

A portion of the proceeds of every Manis Iteritas Alia sold goes to pangolin conservation.

Notes: Tangrams

Push (or Pulse) the Envelope

Snappy, classically analogue envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator, integrated VCA, and trigger buttons -then double it-now you've got Tangrams.

Tangrams, like the Dual ADSR before it, is a dual analogue core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, Intellijel have added a voltage-controlled pulser circuit to link the triggering of two envelopes - allowing for delayed one-shots, cycling organic envelopes, and more. In addition, Intellijel added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you'd like to envelope - freeing up your other VCAs.

The Pulser

The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot sequence). The panel switches for routing or disabling the pulse sources allow for even more complex combinations of control beyond these examples. This special combination of functions can yield a plethora of interesting and organic envelope and gate patterns to be created; cyclical and single shot.

ADSR + VCA Features

Notes: Silver version of Cosmotronic's Messor module, offering stereo compression and transient shaping in just 8 hp. Ideal for mix buss compression, whether full stereo mix or drum/synth submixes.

Supplier's Notes:
Messor is an analogue stereo compressor with lots of tricks up its sleeve, in only 8HP.

From squashing drums, sidechaining kicks and sculpting transients, to glueing a mix together, it's a very versatile dynamics manager.

At its core it's a VCA based feed-forward compressor with a low noise signal path. The magic is in the internal sidechain that shapes the gain reduction envelope. This starts with a a switchable high-pass / low-pass filter, before going into a precision envelope follower, controlled by familiar parameters: the attack, release, threshold, ratio and makeup gain.

The ratio can go past limiting and into over-compression, which can completely reshape transients, a great tool for sound design.

Being modular, of course there are CV inputs for Attack, Release and the side-chain Filter cutoff. The Gain CV controls the makeup gain, but also doubles as a Stereo VCA with the Gain knob turned fully CCW.

The gain reduction envelope is also available as an output, for turning filters or other VCA's into compressors for example, or as a standalone envelope follower.

There's a bypass switch, and a Warm mode, that can bring in a bit of additional saturation and compression in the form of analog tube simulation circuitry.

Lastly there's the possibility to insert an external sidechain, for that classic kick sidechain compression.

Notes: A unique analogue percussion module, based on principles from the legendary 909 twisted into new sonic territory. Capable of everything from classic kicks and snares to more experimental hits and complex VCO effects.

Supplier's Notes:
A machine is born

The Machine began as a quest to create a rich-sounding eurorack snare drum synthesis module to complement the existing Mutant Drums. The project quickly became too large and costly to justify the module being capable only of snare drum sounds. So, the decision was made to learn from the architecture of the TR-909's snare and kick circuits, in order to develop a module capable of generating multiple forms of analogue percussion, and various other effects.

Like the other Mutant Drums, the Machine has its roots in classic analogue percussion synthesis. Even though it can create totally alien sounds, it still has the capability to deliver those classic 909 house snares and kicks if you want them. There are no microcontrollers in the Machine. The signals and waveforms are all generated by discrete components and ICs, for a distinctly analogue sound, and user experience.

Features

Microcontroller-free analogue percussion synthesis engine
Unique Inverter Core oscillators form the MEMBRANE. Each analogue oscillator has three waveforms to select from
Capable of synthesizing everything from heavy-hitting bassdrums to classic 909-style snares and other complex timbres
Modular design gives the Machine many auxiliary purposes, great for modular sound design of many varieties, and not just percussion
The SNAPPY section is comprised of a voltage controlled noise oscillator, for modelling the noisy part of drum timbres
Both MEMBRANE and SNAPPY elements have an external input for replacing the built-in sound sources, opening up many avenues of possibility
13 control voltage and audio inputs, for a fully modular drum experience
7 audio and CV/gate outputs for maximum integration with other modules
Dedicated outputs for each WAVE and NOISE oscillator mean you can use the Machine as a complex VCO in your system, when not synthesizing percussion
Waveform scanning feature generates complex timbres from analog waveforms
The MEMBRANE's waveforms can be scanned through automatically by the wavescanner's voltage controlled clock generator, or an external clock or VCO can be used
SCAN FREQ CV forms a unique form of timbre control, making the Machine act like a complex oscillator at its WAVES output
The ENABLE input allows you to gate the wavescanner on and off with a CV or gate signal

Notes: Cylonix and Intellijel have collaborated to bring you a very sophisticated and deeply complex Wavetable VCO. At the core of this module is very powerful FPGA board that he has pushed to the absolute max of its capabilities and crammed full of features. We wanted to create a module that really worked well in the modular context so there are a lot of modulation and control possibilities.

CHORDS
Oscillator 1 can be operated in a CHORD mode, which runs 8 copies of the oscillator in parallel with adjustable detuning, leading to very fat, rich waveforms. The oscillators have extensive modulation capabilities including audio rate (98KHz) Frequency and Phase Modulation (FM and PM) via external sources. Nonlinear combination processes allow the outputs of the two oscillators to interact to generate complex timbres and sonic textures.
There are 64 user selectable chords.

WAVEFOLDER
The SHAPESHIFTER module also includes the analog wave folder circuitry from
module to add analog warmth and metallic rasps to the digital oscillator output.
External signals can also be patched in.

PRESETS
The module includes a sophisticated preset mode where panel settings can be stored. There are 12 user-programmable preset slots and another 52 volatile slots that can be used as a scratchpad. These scratchpad slots are initialized to interesting presets on module powerup. The capabilities of the preset mode is not limited to mere passive storage of settings, however. In this mode the user can also step through, or sequence, the settings, either in order or randomly in response to pulses input to the external sync input. This gives the user the ability to generate complex sequences of sounds. The preset mode also allows the user to morph between the current panel settings and a preset providing a very powerful real-time performance tool.

SYNC
8 Different sync modes: HARD, SOFT, REV, HOLD, BUMP, 2=1, 1=2, OFF
with the ability to internally sync to a sub oscillator

PULSE
User selectable modes for the PULSE output: OR, AND, XOR, GLCH, +OSC1, EOC, +OSC2, -OSC2

MOD A modes: (audio rate modulation)
COMBO IN, SHAPE IN, PHASEMOD, VOCODER

MOD B options (all with CV control)

-Combo modes for OSC1 and OSC2:
NORMAL, RING, MIN, PONG, INLV, AND, XOR, GLCH
-Waveform TILT
-Chord mode overdrive
-Delay depth and FB
-Percussive mode decay time

Notes: FONT is a massive sounding liquid filter- designed to bring you powerful basslines, tons of FM modulation and a clean resonance over your audio path.

It features two simultaneous outputs:
2-pole Low Pass
2-pole Band Pass

It can also work as a sine oscillator, tracking 1V/OCT when the resonance is at its maximum level.

FONT can be used to make basslines, acid patterns thanks to its organic and musically sounding resonance.

Ping it to produce percussion sounds such as, bongos, congas or toms.

Applying a pitch envelope, it really shines as a kick-drum machine!

Notes: While ADDAC were working on the new VC Stompboxes several expression pedals were tested and it became clear that most often, while playing a modular system, your hands are busy.
It's also normal to have an expression pedal lying around somewhere, so ADDAC have brought these back, cleaned up the dust and put them to good use.
This module allows the connection of any standard expression and sustain pedal.

The expression pedal action can be fine-tuned with Range and Offset knobs.
Range defines the voltage range (-10v, +10v).
Offset transposes the range by (-5v, +5v).
Two leds, plus and minus, monitor the CV Output
Positive and inverted output jacks.
The sustain pedal action will generate a gate signal on the gate output.
One led monitors this output.
The module also features a bus board +5v Adaptor, this will be able to provide +5v to any bus board.
This feature can be removed through a jumper on the back of the module.

Notes: For decades, the voltage controlled slew limiter has been a staple of modular synthesisers. With its extreme versatility, it can be used to slew control voltages (CVs), create envelopes, as a low-frequency or audio oscillator and much more.

Today, Contour 1 brings a fresh approach to this classic circuit. It delivers much improved performance and control by incorporating modern design techniques.

At its most basic, a slew limiter slows down the rate of voltage change in a signal. On Contour 1, the rising and falling rates can be individually set using sliders and CV modulation.

The gate and trigger inputs allow the module to be used as a function generator: create snappy attack-release (AR) and attack-decay (AD) envelopes, with slope times ranging from 500 us to 30 seconds. The dedicated gate input makes it easy to generate +10 V envelopes from any signal source. Using the large tactile push button, AD envelopes can be manually triggered. A trigger will also reset the output voltage.

When set to loop mode, Contour 1 will continually re-trigger itself. In this mode, it fulfils the role of a variable-shape low-frequency oscillator (LFO) or temperature-stable voltage controlled oscillator (VCO) in the audio range.

Both the rising and falling slopes can be individually bent, from concave through linear to convex. While doing so, the deviation in slope time, and thus oscillation frequency, is kept to a minimum. Since the bend parameters are separately voltage controllable, boundless modulation possibilities present themselves.

Explore anything from shape-shifting envelopes to rich VCO timbres: Contour 1 will make you re-think what a slew limiter can do.

Notes: Module A-160-2V is an enhanced version of the standard clock divider A-160. The module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses.

The Clock input will take any digital signal from, eg., an LFO, MIDI sync, or the gate from a MIDI-CV interface. At the outputs, you have access to three sets of seven different sub-divided clock signals, from half the clock frequency down to 1/128. The low/high levels of the output signals are 0V and about +10V.

The A-160-2V also has a reset input. Whenever a reset signal is sensed, all outputs are set to certain levels which depend upon the selected mode.

Notes: Any signal can be expressed in terms of a few parameters: frequency, phase, amplitude and timbre. It is through modulation of these aspects that synthesists create electronic sound. With Generate 3, it is now possible to create a signal and control all its parameters by through-zero modulation within a single 12 HP wide module.

Everything starts with the exceptionally precise triangle-core voltage controlled oscillator (VCO) at the module’s heart. Through-zero linear frequency modulation (FM) enables rich yet pitch-stable FM sounds, by allowing the oscillator to run backwards into ‘negative frequencies’.

The resultant triangle wave is then processed by the through-zero phase modulator, providing a total phase shift range of 900°. Phase modulation offers an interesting alternative for FM, as it enables deep FM-type tones without actually changing the oscillation frequency.

The timbre of a signal is determined by its harmonic content. This full set of harmonics can be grouped into three main parts: the fundamental, even and odd harmonics. Generate 3’s harmonics generator separates out these three timbral ‘channels’. By adjusting their relative amplitudes, a vast array of different waveforms can be created, including but not limited to the classic sine, saw and square waves.

While the amplitudes can be adjusted manually, each timbral channel supports through-zero amplitude modulation, also known as balanced or ring modulation. When audio-frequency modulation signals are applied, the harmonics become ‘split’, enriching the spectrum.

In addition to all the usual analogue synthesis techniques, the extensive set of modulation options makes Generate 3 especially suited for exploring multiphonic synthesis: a monophonic source creating a complex timbre, much like throat singing, yet by electronic means.

Notes: Expander module adds four more assignable CV inputs to Squid Salmple for advanced modulation and sample manipulation. A must for all Squid Salmple owners.

Supplier's Notes:
AXON-1 is a 4HP expander module for the SQUID SALMPLE that provides 4 additional freely assignable CV inputs.

The addition of AXON-1 brings Squid's total number of CV inputs to 7, greatly increasing the possibilities for vast modular sample manipulation.

Each modulation assignment includes digital attenuation and offset and behaves just like Squid's 3 built in CV inputs.

AXON-1 requires firmware 166 or later installed on the Squid Salmple to function!

Notes: THE SBG-PRO supports mono, stereo, balanced, and unbalanced input and output via 6.35mm jacks with level matching controls with clipping indication. The module features both direct and voltagecontrolled equal power crossfading between wet and dry sources.

Additionally, an expression input, along with the included 'floating ring' cable and conditioned output, ensures safe, voltage-limited CV control of external devices from your modular system.

The module extends its sibling, the original S.B.G, by adding full size stereo balanced jack connections and voltage control focusing more on connectivity with not just pedals but also pro audio equipment including rack effects, 500 Series modules and mixing consoles.

Notes: The Dual Stereo Gate (DXG) music synthesizer module is a Dual Stereo Low Pass Gate and Mixer. It follows in the footsteps of the QMMG, Optomix, RxMx, DynaMix, and LxD. Unlike its predecessors, the DXG is specifically oriented around mixing stereo signals, making it an important addition to any system containing modules like XPO, QPAS, Morphagene, Mimeophon, and other stereo modules by Make Noise or others.

Unique to the DXG is a new low pass gate circuit that does not use vactrols. This circuit is 100% analogue and its response was arrived at after many months tailoring it to meet or exceed the expectations that have been set by all the vactrol low pass gates that Make Noise has created over the years.

In the past, Make Noise produced the Dynamix module and Dynamics circuit in the 0-COAST, both of which are vactrolless LPGs; however, the DXG is a completely new approach which better implements the gentle single pole filtering of a low pass gate, while also emulating the slow decay and memory of the vactrol based low pass gate. This new circuit makes possible the consistency of response necessary for versatile stereo use, while also keeping the module small and affordable so that it can be a key part of just about any modular system.

As on all of Make Noise's low pass gates, the DXG's Control parameter is used to set both the amplitude and the frequency content of the sound that passes through it. The control parameter tends to open faster than it closes, imparting a subtle decay phase onto any envelope shape that is used to modulate it.

Unlike previous low pass gates made by Make Noise, all the DXG's inputs and outputs are stereo. Each set of inputs is normalled so that the left input can be used for a mono signal, sending a copy to both left and right outputs. The Auxiliary inputs are also a stereo pair with mono normalization. These normalizations allow for the DXG to be used as a simple three channel stereo mixer, with one or two of the channels additionally being used for dynamics control and note event generation. The Aux inputs can be used to chain together larger decentralized mixes using additional DXG modules, or X-PAN, Optomix, modDemix etc.

Features

- Make Noise's first Stereo Low Pass Gate

- Vactrol-free design for classic Low Pass Gate sounds, but with the balance and consistency needed for true Stereo

- Fully Stereo i/o for easy integration into a Stereo-equipped modular synthesizer

It features AS3340 VCO with three waveforms, a filter inspired by Erica Synths Acidbox and unique features - transistor based suboscillator and two BBD lines that emulate VCO detune creating a sound of massive polysynth from one oscillator.

Accent provides more expression to the bassline, by adding volume and opening the VCF slightly.

Notes: Module A-138m is a 4 x 4 matrix mixer with switches for unipolar/bipolar mode for each column. Unipolar means that the controls work as attenuators. Bipolar means that the controls work as polarizers. In this mode the amplification is zero in the middle position of the corresponding control. Turning the knob counterclockwise from the center position the signal is subtracted from the output sum with increasing amount (i.e. negative). Turning the knob clockwise from the center position the signal is added to the output sum with increasing amount. The module is DC-coupled and can be used for both audio and control voltage mixing.

By means of an internal jumper one can select if the four upper controls work as DC offset generators - provided that no patch cord is plugged into the upper input socket. If this feature is not required it can be deactivated by removing the jumper on top left of the pc board. The function is identical to the A-138a/b.

Notes: Scales is an 8hp dual-channel note quantizer and step sequencer. Fundamentally, it takes an input voltage, quantizes it to notes in a user-defined scale, and sends that quantized voltage to an output, where you can use it as a melodic pitch source for oscillators or any other module that expects to see discreet note values at its input.

Scales goes far beyond the fundamental, allowing you unprecedented control of the pitches and intervals hiding inside your control voltages; turn LFO's into arpeggiators; random voltages into harmonic counterpoint; and unquantized external CV sequencers into chromatically tuned note sequencers.

Quantization can be locked to an incoming trigger. There are a number of trigger output options as well, ranging from no triggering (good for pitch shifting drones); through triggers that sync with either of the two outputs (or both); to a trigger or gate transmitted in sync with one sent to the module's TRIG input.

Shift:

Scales features two independent outputs, enabling you to create shifted harmonic intervals within your chosen scale using only a single pitch input. Using the SHIFT input you can modulate changes on OUT A and/or OUT B.

You can also use the shift input to switch between scales or to change the root of any existing scale pattern or split Scales into two quantizers - each conforming to a common scale, but fed entirely different voltage sources.

Sequence:

Scales also features a 128-step SH-101 style step sequencer (complete with storage for up to 35 fully programmable patterns) - allowing you to feed OUT B with sequenced notes and rhythm patterns, while OUT A continues to function as a standard pitch quantizer for external voltages. You can even sync the sequencer to quantizer events on OUT A.

Notes: The Quad Peak Animation System music synthesizer module combines the auditory enveloping of stereo spaced peaks with the animation of two or more peaks in a single channel dancing around each other or engaging in primitive vocalizations.

Everyone who knows a bit more about electronics will point out that stackable patchcables are not a really wise choice for such sensitive things as musical instruments because they mechanically connect electrical signals that at best can cause undesired modulations or even damage the modules.

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, design and usability were prioritised first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.

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: Reverb. Well...kind of.

Welcome to Aurora, a spectral reverb capable of a wide palette of sounds: from lush caverns and whale songs, to alien textures you've never created before. And likely, will invoke a hunger for exploration you felt when you first touched a modular synth.

Aurora uses a phase vocoder audio engine which separates the input signal's time and pitch domains. By blurring these signals you can achieve beautiful time-stretched tails, or cybernetic metallic effects.

Since Aurora's sonic response is entirely dependent on the input signal, no two patches will sound alike, lending itself to an infinite world of surprise and discovery.

Discovery. It's why we are all here.

A portion of all Aurora proceeds will help the fight against shrinking ice caps and dwindling polar bear populations.

Notes: Module A-183-9 is a simple power supply for up to four devices which can be powered via USB (e.g. keyboards, smartphones). An LED shows is the +5V are present.

The module has no USB function but provides only the +5V supply for USB devices.

A control LED shows if the +5V are present.

Note: The module requires an A-100 case with built in power supply A-100PSU3. Only this A-100 supply has the required +5V available. We do not recommend the usage of an older A-100 case with A-100PSU2 as this would require the +5V adapter A-100AD5 and the max. current would be limited to 100mA.

Notes: Module A-196 contains a so-called phase locked loop (PLL). The basic PLL system is shown in the sketch at the bottom of this page. A PLL consists of three parts: voltage-controlled oscillator (VCO), phase comparator (PC), and low-pass filter (LPF). All parts are normally connected to form a closed-loop frequency-feedback system.

This is how a PLL works: The output of the internal VCO (linear CV control, rectangle output) is compared with an external signal (e.g. the rectangle output of a A-110 VCO) in the so-called phase comparator (PC). The output of the phase comparator is a digital signal (low/high/tristate) that indicates if the frequency resp. phase difference of the two input signals is negative, zero or positive. The output of the phase comparator is processed by a low pass filter (LPF) to generate a smooth voltage that is used to control the frequency of the internal VCO. The 3 units VCO, PC and LPF form a feedback loop that works like this: The control voltage (output of the LPF) increases as long as the external frequency is higher than the frequency of the internal VCO und stops increasing when both frequencies become identical. The control voltage decreases as long as the external frequency is lower than the frequency of the internal VCO und stops decreasing when both frequencies become identical.

But there are some stumbling blocks: Different types of phase comparators with advantages and disadvantages can be made. Some phase comparators e.g. even lock at harmonics, i.e. if the two frequencies to be compared are integer multiples. But for some applications this can be used to create interesting effects. The A-196 contains 3 different types of phase comparators: PC1 is a simple exclusive OR, that even locks at harmonics. PC2 is a so-called RS flipflop and PC3 a more complex digital memory network. The user can select one of the three phase comparators with a 3-position switch. When PC2 is used a LED displays the "locked" state, i.e. when the frequency of the internal VCO is identical to the external frequency.

Special attention has to be directed to the frequency of the LPF. To obtain a smooth control voltage for the VCO the frequency of the LPF has to be much smaller than the lowest frequency of the internal or external audio signal. Otherwise the frequency of the internal VCO will jitter or wobble around the correct frequency. But for special effects this frequency jitter can be used intentionally. Example: frequencies in the range 50Hz...1kHz have to be processed with the PLL. Therefore the frequency of the LPF has to be about 10Hz or even less. Such a low frequency of the LPF causes a noticeable slew of the internal VCO. When the frequency of the external signal jumps e.g. between 500Hz and 1kHz it takes about 0.1 second until the internal VCO reaches the new frequency (like portamento). So one has to find a compromise between frequency jitter and portamento. But these remarks are valid only for the "ideal" working PLL. As the A-196 is used in a musical environment the "problems" and disadvantages with jitter and slew time lead to additional musical applications like portamento effects, wobbling frequencies or harmonic locking according to the type of frequency comparator and time constant of the PLL low pass filter. Instead of the internal manually controlled low pass filter the voltage controlled slew limiter A-171 can be used to obtain voltage control of this parameter. Normal audio filters (e.g. A-120, A-121) cannot be used for this job as the minimum frequency is to high (down to a few Hz or even less necessary) and the signal has to be DC coupled due to the low frequencies. Audio filters are normally AC coupled.

Another very important application of a PLL is frequency multiplication in combination with an external frequency divider. For this the output of the PLL-VCO is processed through an external frequency divider (e.g. A-163, A-160, A-161, A-115) before it is fed to In1 of the phase comparator. In this case the frequency of the PLL-VCO will be a multiple of the master frequency. E.g. if the A-163 is used and adjusted to dividing factor 5 the frequency of the PLL-VCO will be 5 times the frequency of the master VCO. Consequently, frequency division (A-163) leads to frequency multiplication with the PLL circuit. In combination with the PLL low pass frequency several effects can be realized (frequency multiplication with portamento or wobbling). The frequency multiplication can even be used to drive a graphic VCO. If your graphic VCO e.g. has 8 steps (e.g. A-155) and you use a frequency divider with factor 8 in the PLL feedback the output of the graphic VCO has the same frequency as the master VCO. Another application is the generation of pseudo-harmonics (not real harmonics as only rectangle waves are available) or clock generation for switched-capacitor filters.

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: A comprehensive solution for stereo signals in Eurorack, the Enhance 2 offers stereo and mid/side processing with tons of CV control. Balance, widen and sculpt frequency bands.

Supplier's Notes:
Moving from mono to stereo sound: a logical progression for any synthesist looking to expand their sonic palette. Making use of two audio channels, rather than just one, quite literally adds another dimension to the capabilities of a synthesiser.

Unfortunately, controlling stereo signals can be a challenge within a modular system. This realisation led to the development of Enhance 2: a convenient yet high-fidelity tool for stereo enhancement. It can be used to adjust balance, width and spectral content, while also opening up a world of mid/side processing; all under voltage control and in just 8 HP.

The primary stereo parameters are balance (moving the sound left or right) and width (making it narrower or wider). The balance circuit uses a true constant-power gain law, while the width stage allows for seamless transitions from pure mono to extra-wide stereo.

In addition, tone control is provided by a pair of unique, wide-ranging mid/side voltage controlled tilt filters with selectable corner frequency. These make 'cleaning up' a muddy-sounding mix straightforward, but also provide unique binaural effects when modulated.

Mid/side processing encodes the stereo signals into one containing only the mono material (mid), and another containing the differences between both channels (side). Apart from the internal tilt filters, mid/side outputs also enable external signal processing such as compression or reverberation. An integrated mid/side decoder returns the results back to standard stereo. And at all times, a LED bar phase meter ensures that phase correlation can be easily maintained.

Stereo field modulation, mid/side equalisation and beyond; Enhance 2 brings true analogue stereo control to the Eurorack world.

Notes: Describing Univer Inter as merely a MIDI-to-CV module falls short of its immense potential. It serves as an all-encompassing MIDI-to-any-format converter, elegantly packed into a compact 6 HP unit. Connect to your gear via USB B or TRS MIDI, or use the included adapter to plug straight into those 5-pin DIN connecters we all know and love. Whether you're looking to map clock, note, CC, aftertouch or something else that MIDI can encode, UI can do it: we built in over 20 settings for each of the 8 outputs.

Want to control a pair of monophonic voices, complete with velocity and aftertouch? No problem. How about a polyphonic setup, with gate and pitch per voice? Easy. Need to synchronize an in-the-rack sequencer with your DAW or a MIDI clock? UI has you covered.

Eight outputs isn't enough, you say? Chain two UI together via their front-panel MIDI ports and a TRS cable for 16 - you read that right, 16 - configurable CV outputs from a single MIDI connection. The possibilities are endless.

Noise Engineering also made configuration simple via the front-panel USB connection and the easy-to-use Univer Inter section on the Noise Engineering Customer Portal. Go wild and set each channel to any output option you need, or just use one of our simple presets. Configuration files can also be saved as sysex files for easy backup and sharing.

Notes: Oof. Frap casually serve up one of the best filters we've seen in a long time. Quad multimode circuits with saturation and feedback give you extensive routing options. Delicious.

Supplier's Notes:
cunsa /'cu?nsa/ s.f. [dialect of Modena of uncertain etymology, probably from a Latin *comptiare, derived from comptus, participle of comere 'organize,' 'decorate'] i curing, seasoning (of foods), tanning (of leathers).

Seasoning is crucial for cooking. It is a process that enhances the flavors, glues the ingredients together, and even adds some unexpected kick.

From a gentle refining touch to a shovelful of spice, CUNSA is the perfect seasoning tool for your patches. It can sweeten a sour lead or beef up an insipid bass line, and anything in between.

And, just like a good oil, you can even taste it by itself!

CUNSA is a quadruple analog pingable multimode resonant filter, saturator, mixer, and oscillator.

It is Frap Tools' sound seasoning tool: it can gently even a patch, applying a final touch, or it can set it on fire with a ridiculous amount of spice. It's up to you and your cooking style!

It consists of four multimode resonant filters with a custom saturation and feedback control that you can use independently or in various combinations and roles thanks to a series of seminormalizations.

Four Analogue Resonant Multimode Filters

CUNSA features four state-variable filters that can be used independently or linked and mixed. Each filter provides three behaviors simultaneously: lowpass, bandpass, and highpass. Each behavior has a 12 dB/oct slope, except for the lowpass, which can be either 12 or 24 dB/oct.

Unique 'Character' Circuit for Feedback and Distortion

CUNSA handles feedback and gain staging with extreme control and versatility. Besides the usual Q control that emphasizes the cutoff frequency, the Character circuit defines the amount of soft clipping when the filter overloads. High clipping guarantees a controlled behavior with fat tone and pure resonance, while low or no clipping lets the signal saturate the filter stages and make it scream.

V/oct Tracking and Quadruple Oscillator

Each filter responds to the V/oct signal with excellent tracking. It is thus possible to move the cutoff frequency along with the main melody or make CUNSA resonate with no input and transform it into a multiple oscillator. The V/oct inputs are seminormalled so you can control more filters with the same CV. Easy chords stabs!

Ping and Ring

CUNSA is ideal for percussive and organic tones. The Ping circuit offers a behavior similar to the BRENSO but AC-coupled. Instead of shooting the frequency to the moon with any trig, CUNSA gently responds to different incoming gates with a selectable decay curve. The Ping circuit can thus create natural decay sounds when fed with trigs or smoother envelopes with any other voltage, like a linear integrator with a custom decay.

Besides this, you can also feed the filter's audio input with trigs and make it ring at high Q settings.

Linked or Individual Filtering

The four filters can work independently or arranged in groups through seminormalled inputs and sum outputs. CUNSA can thus be a 4×1, 2×2, or a massive 1×4 filter. Even odd configurations are possible, like 1+2+1 or 3+1. Mono, stereo, or quadraphonic audio is at your fingertips.

Filter and Combo Behaviour

When the filter behavior is set to COMBINED, every control of the cutoff frequency also affects the input VCA, reducing the signal amplitude and saturation as it approaches the lowest range. It can make organic decays with the ping circuit or tame the low range at high Q and Character settings.

Four Seminormalizations for Group Use

Four inputs have a cascaded seminormalization: audio inputs, VCA CV, V/oct, and Ping. Every signal patched to a filter will thus feed also those at its right, making simultaneous use even simpler. To remove a seminormalization, simply patch a dummy cable to the corresponding input.

Analog Mixing Stage and Group Outputs

Every filter output can be routed to an analogue mix bus that sums the four filters and outputs them in three combinations: all, 1+2, and 3+4. These outputs allow for versatile audio processing. Just like we did with FUMANA, we added a gentle shelving EQ for the higher frequencies of the All output to provide additional timbral variety.

CV Inputs with Attenuators

Besides the seminormalled inputs, every filter features additional CV inputs for cutoff frequency, Q, and Character, each with a dedicated attenuverter.

Notes: An expander module for Rossum's powerhouse Assimil8or sampler module, the Locutus provides MIDI in, out and thru connections over 5-pin DIN sockets, letting you take full control of the module alongside other MIDI gear.

Supplier's notes:
Locutus is designed to interface Assimil8or with MIDI instruments, controllers, and sequencers to provide multichannel modulation and new polyphonic possibilities.

Locutus includes a special cable to connect to the Assimil8or CPU behind the panel.

Locutus is 6 HP wide and 25mm deep.

More pricing and availability information is coming soon.

Locutus is on display in the MIDI Association booth #9901 at NAMM 2023 where Locutus and Assimil8or will be performing with a Rossum SP-1200 Reissue, an Oberheim OB-X8, and other new and vintage MIDI-equipped instruments.

MIDI Association booth #9901 is dedicated to the MIDI@40 Lifetime Achievement Award winners, including Rossum Electro-Music co-founder Dave Rossum.

From the MIDI Association: "At Saturday's anniversary celebration, lifetime achievement awards will be presented to (or posthumously honour) legendary music industry innovators who created the modern music production environment of synths, drum machines, and sequencers, including Bob Moog, Don Buchla, Ikutaro Kakehashi, Tsutomu Katoh, Roger Linn, Tom Oberheim, Alan Pearlman, Dave Rossum, and Dave Smith."

Notes: Module A-124-2 is a special 12dB multimode filter using the "strange" filter circuit of the "EDP Wasp" (an analog synthesizer with black/yellow case built end of the seventies, manufactured by the UK company "Electronic Dream Plant").

The A-124-2 is the Slim Line version, which is only 4hp wide.

This design "abuses" digital inverters as analog operational amplifiers leading to distortions and other "dirty" effects that generate the specific sound of this filter. The filter is equipped with a band pass output and a combined low/notch/high pass output. For this output a control knob defines the relation between low and high pass signal. If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates. The module does not feature self oscillation in contrast to most of the other filters of the A-100 system.

Notes: Dual-channel wavefolding with a lot of creative power. Buchla- and Serge-style circuits combine with a voltage-controlled crossfader, allowing you to shape and sculpt sounds in intriguing ways.

Supplier's Notes:

Bifold is a unique dual channel wavefolder with numerous feedback and routing options along with CV control. Mix, blend and crossfade the two different folder flavours into a rich stew of unique waveforms and harmonic movement. It is the first wavefolder to offer simultaneous, independently controllable serial and parallel folder circuits.

Wavefolding is one of the most powerful ways to produce complex timbres out of a simple sound source or waveform. When done well, the results can be warm, textured, organic and full of musical character. Intellijel studied some of the most revered wavefolding circuits and looked at ways to integrate the positive qualities of these into a design that was full of sweet spots and allowed for a huge amount of experimentation and modulation.

Bifold combines two unique wavefolders with a crossfader; One channel (the P channel) has a sonic characteristic inspired by the Buchla-style Parallel "deadband" folding circuit, while the other channel (the S channel) is more characteristic of a Serge-type Serial folding circuit. There are distinct differences to how they react to specific waveforms, modulation and even their overall frequency response. By linking both folders together with a voltage controlled crossfader we further expand the ability to blend these two different folders together to create new waveforms. But this just scratches the surface of possibilities. Ring modulation, blending, crossfading, complex noise generation, feedback modulation, cascaded folding and so much more are all possible thanks to the strategically placed routing switches, jack normals and attenuators and other control options. This is a module that invites much exploration and discovery and pairs well with almost any kind of modulation and sound source.

Supplier's Notes:
The Erica Synths Black Sequencer takes classical modular sequencing to the next level by adding tons of features required for contemporary modular synthesizers.

The Black Sequencer features 4 channels with CV, gate and modulation outputs, up to 64 step sequences that can be chained into songs, independent track time divisions, multiplications and lengths. It includes a built-in quantizer, LFOs, envelope generators, parameter randomization, a MIDI in/out and many other features essential for composing and performing electronic and experimental music. Even though it provides many programmable parameters per step, it's intuitive, easy and straightforward to use, and could well become a master controller for many modular setups.

Black Sequencer firmware 1.04 is now available!

It adds output quantiser which can quantise track outputs in real time or rewrite notes in the sequence. Update also adds new track and synced LFO time divisions.

Notes: 3xMIA is a 6-channel attenuverting mixer/offset/scale/polarizer

3 blocks of 2-channel attenuverting mixers, using dual concentric pots. Each channel can be switched to mix with the subsequent channel, allowing for 2-2-2, 4-2, 6 mix configurations.

With nothing plugged into an input, an offset is normalled to that channel. The inner knobs control the A inputs, while the outer knobs control the B inputs.

DC coupled, so it can be used for audio, CV, or both at the same time.

Notes: Really neat stuff from Hexinverter. Designed with synth sounds and drum processing in mind, the Hot Glue is a unique twist on a four-channel mixer, helping to integrate effects and voltage-controlled distortion alongside built-in bus compression.

Supplier's Notes:
The Mutant Hot Glue is a versatile bus mixer for analogue effects chain design. The included analogue compressor offers series or parallel compression and a sidechain input, making it particularly well suited to drum processing. The voltage controlled distortion is based on ideas borrowed from the guitar pedals responsible for a lot of yesterday's acid style techno sounds, but improved over the guitar equivalents, and made specifically for synthesizer and drum processing. The distortion can be used in its default position, normalized to the effects send, or like every other part of the module, broken out and used elsewhere in your modular system.

Features

4 Channel Mixer with Effects Send

4 input channels, each with their own level and effects send control
Channel A mixer bypass switch and dedicated output for easy sidechain compression
Channel B is dual input, but shares level/send controls (for dual output modules, like the Mutant Hihats)
Channel C+D summed output
Main mixer output normalized to compressor input

Hi-Fidelity Analogue Compressor

Soft-knee compressor based on the same family of premium audio ICs used in some 500 Series studio gear
Dedicated threshold and compression ratio controls
Gain control dials in up to +40dB of compressor make-up gain
Compressor sidechain input for creating pumping effects
LED indicator actively displays the amount of compressor gain reduction

Voltage Controlled Analogue Distortion

A classic distortion topology reborn for modular analogue synthesizers and drum processing
In/Outputs are conveniently normalized to the module's send and return jacks
Blend control lets you adjust the mix of distorted and clean input signal
Fast responding CV input allows for complex modulation patterns and even modulating with audio signals

By default, the 4 channel mixer's output conveniently feeds into the compressor's input, giving access to easy New York style parallel compression by way of the compressor blend control. The dedicated output and mixer bypass switch for channel A allow you to use it as a sidechain source for the compressor. An effects send and return allow you to create complex effects routings within your modular system. With the number of excellent DSP and other effects modules on the market today, this makes it easy to combine modules to great effect, all within the eurorack modular domain.

Redesigned by Erica Synths in close collaboration with Hexinverter. Minor alterations were made in mechanical assembly and digital controls to address Erica synths manufacturing routines and chip shortages, but the analogue signal path is 100% identical to the original version.

In September 2022 Stacy Gaudreau - the founder of Hexinverter Electronique, announced closing down the operations. Following their announcement, Erica Synths in cooperation with Hexinverter Electronique saw a way for their incredible and truly unique music instruments to keep on inspiring musicians and finding a home in countless studios to come.
The effort and innovation incorporated in Hexinverter Electronique eurorack modules are far too great to prematurely become history. Erica Synths will take over the manufacturing, sales, and support of several Hexinverter Electronique modules. While retaining all functionality of Hexinverter Electronique modules, Erica Synths redesigned the hardware of modules and will provide support for reissue modules only.

Notes: Building on the familiar dual VCO core arrangement of Carrier and Modulator, Mindphaser is a complex oscillator which departs from this bit of ancestral DNA with a modern toolkit focused on searing, phase-modulated leads, percussive basslines and other-worldly effects!

A diverse palette of intermodulation and harmonic experimentation is offered through the Modulation Bus, its unique Waveshaper and the dedicated Thru-zero Phase Modulation Bus. An intuitive interface provides colour-coded visual feedback and responsive indication while performing in dimly-lit environments.

Two precision analogue oscillator cores

Precision, wide-range V/oct ramp cores, each ranging from deep subsonic to supersonic frequencies (ramp cores, and not triangular, deliver the ideal waveforms for analogue phase accumulation in the TZ-PM Bus)
Each core generates fundamental waveshapes which interact and mangle one-another through the complex Modulation Bus and TZ-PM bus
Simultaneous waveform outputs for each base shape
Dedicated button to toggle between RAMP or SAW for each core, inverting the phase of the ramp output
V/oct, linear FM and exponential FM inputs which are all independent of the TZ-PM functionality. The Carrier's FM occurs inside the core itself, separate from the TZ-PM bus.
DC-coupled linear FM

Carrier

The heartbeat of Mindphaser, focused on audio-rate generation. Drives the WAVESHAPER and TZ-PM bus. This core's frequency range spans the audible spectrum.

- An external hard SYNC IN forcibly resets the core, useful for punchy sequences, percussive basslines and drum synthesis -- or to sync to another VCO.

- Coarse and fine controls conveniently span the audible spectrum. Ranges further with external CV.

Modulator

An extremely wide range oscillator, spanning from deep LFO frequencies all the way up to supersonic sound! Four base waveforms and diverse internal routing options form a versatile palette of modulations for the CARRIER to feed on.

- Activating hard SYNC on the Modulator locks its core to the Carrier's heartbeat. The effect can be dramatic. Try this while phase modulating!

- Octave RANGE switch lets you quickly flick up and down between octaves. All the way beyond audio-rate and LFO speed octaves. Perfect for experimenting with different PM sidebands and taming the wide frequency range of the Modulator.

- Manual PW (Pulse Width) control and dedicated CV input for PWM.

Waveshaper

This isn't a classic waveshaper! Developed anew from the ground up, this waveshaper is focused on deep harmonic experimentation and audio obliteration. Each waveshaper parameter is capable of being "turned up to 11".

FOLD up to 5 octaves above the fundamental Carrier frequency. A ceiling forms at maximum, imparting additional harmonics.

FEEDBACK the waveshaped and phase-modulated audio through a signal path internal to the waveshaper.

AMPLITUDE modulation spans thru-zero, allowing for full-range ring modulation effects with bipolar CV or audio signals.

CLIP the final stage of amplitude with the switch to introduce a last stage of harmonics before the complex signal exits through the final OUT.

Switchable inverting attenuators on each CV input, for quickly inverting the behaviour of your modulation. The indicator illuminates red to tell you the attenuator has been inverted.

Two distinct waveshaping modes

A press of the shape switch toggles Mindphaser between RAMPOID (green) and TRIANGULAR (yellow) waveshaping modes.

These modes have a remarkable effect on the behaviour of wavefolding and overall character of the final complex OUT, in addition to TZ-PM Bus character.

RAMPOID mode folds more asymmetrically, with raucous, buzzing harmonic artefacts as you sweep and introduce TZ-PM

TRIANGULAR mode folds more symmetric, splitting the complex sine wave at its peak centre of the waveform. TZ-PM character is less raucous, and more smooth.

TZ-PM Bus

Thru-zero phase modulation in the ANALOGUE realm! Unlike its digital counterpart, analogue TZ-PM has its own character we've come to expect from analogue circuitry!

A dedicated, voltage-controlled phase modulation bus completely separate from the Mod Bus
Modulator's SINE wave normalled to the PM SOURCE input
SOURCE input allows you to modulate phase with any signal you patch in
Dedicated voltage-controlled INDEX (amount)
Manual phase lets you zero in (or not!) on the base phase before introducing modulation
Independent of the Linear FM circuitry in the Carrier core

Mod Bus

The internal modulation powerhouse, normally fed by the Modulator core, but external signals are patchable as well.

Select from the PULSE, RAMP/SAW or SINE output of the MODULATOR, or inject your own SOURCE to the bus.

Voltage-controlled INDEX behaves like a macro control when combined with various amounts and polarities dialled in at each CV destination.

Internal sends include the Carrier's classic Linear FM, Amplitude, Feedback and TZ-PM Index, with variable amounts and polarities!

Modulator waveforms internally feeding the Mod Bus behave unipolarly, for predictable modulation of every Mod Bus destination, without external patching. By patching in one of the Modulator's bipolar waveform outputs manually (or any external signal), you can override this behaviour.
