Notes: Bucket brigade delay gets pushed into exciting creative territory with this beauty from Joranalogue. Precise analogue delay with loads of character, capable of simple chorus and flanger or more exotic Karplus-Strong synthesis and comb filtering.

Supplier's Notes:
While digital audio processors are often plagued by latency issues, analogue circuits are known for their instant response. But what if you want to delay a signal on purpose, without the use of tape or digital memory? Enter the bucket brigade delay (BBD) line: a series of capacitor 'buckets', which pass the incoming signal along at a high rate in order to delay it.

Delay 1 is a fully analogue BBD-based delay module with a multitude of features geared towards modern musical use. An integrated temperature-compensated, high-frequency voltage controlled oscillator (VCO) provides the 'clock' signal necessary to drive the delay line within 1 to 50 ms.

By increasing the drive frequency to over 20 kHz, the classic 'BBD clock whine' problem is solved, while still providing a wide range in delay time. Classic chorus, flanger and echo effects are easily achieved using the dry/wet blend, feedback and damping parameters.

To greatly reduce distortion and noise, Delay 1 includes a newly developed control circuit. The improved fidelity is maintained at a multitude of signal levels by an integrated high-performance compander, while maintaining signal dynamics.

The module's 'split phase' topology provides two different dry/wet mixes, which may be used to convert mono signals to stereo, for complementary comb filtering and more.

Delay 1 also allows you to experiment with Karplus-Strong synthesis, an exciting technique to create string and percussion type sounds. This is made easy by an integrated noise transient generator, driven by the 'pluck' input, and by the clock VCO's 1 volt per octave response.

By re-engineering the classic analogue delay line, Delay 1 brings the unique magic of BBDs into the contemporary electronic musician's arsenal.

Notes: Two control sections provide a sweepable cut or boost to a selectable upper and lower frequency band. The module has two ac-coupled audio inputs, one of which has an attenuation control for basic mixing, and a single audio output.

The 'PE-1' is inspired by the EQ circuits used in early 'Portastudio' type 4 track tape mixers. Warm up a digital source, fine control a live performance, extend a mixer, tweak a feedback loop - there are many uses for this great sounding EQ.

Features:
- Provides +/-12db of boost and cut across 2 selected frequency bands
- Dual input with single attenuation control
- Reverse polarity protection.
- Skiff friendly
- Designed and made in the UK

Notes: There are many excellent digital reverbs available these days but there is still nothing quite like the timeless and magical character of a true spring reverb.

For the Intellijel Springray II, each tank has a totally different set of characteristics, with many unexpected surprises when feeding it through a wide variety of sound sources. One of the most interesting results is how a slow attack saw waveform from a Dixie almost sounds like a realistic cello!

Version two of the Springray provides a number of changes and improvements to the original design. The shelving EQs have been replaced with a parametric EQ with frequency, Q, and gain controls. The CV inputs for feedback and mix balance have been replaced with inputs to control the filter frequency and gain. Lastly, the feedback and limiter circuits have been redesigned, and the drive quality has been improved.

PLEASE NOTE: Does not include Spring Reverb Tank.

Notes: Arp is a gate-driven arpeggiator with a multitude of chord types and playback modes. Voltage control over both root note and chord type allow for sequencing any combination of chords in any key imaginable.

Notes: Module A-192-2 contains two independent CV/Gate-to-Midi/USB interfaces. For each of the two sub-units these inputs are available:

- Gate Input (min. +5V)
- CVN Input (defines the Midi note number), 1V/octave standard, range 0...+10V (i.e. 10 octaves)
- CVV Input (defines the velocity value assigned to the Midi note message), can be used alternatively for Midi volume (CC#7), range 0...+5V
- CVC Input (free assignable to any Midi control change number), range 0...+5V

For both sub-units a common CV Transpose input is available (1V/octave, range 0...+10V). The voltage applied to this input is added internally to CVN before the Midi note number is generated. It can be used e.g. to transpose two sequences simultaneously by one voltage.

How it works:

Whenever the rising edge of the Gate input is recognized a Midi note on message is generated. The note number corresponds to the sum of the voltages applied to the CVN input and the common CV Transpose Input that is present at the rising edge of the gate signal.

Notes: Following the ADDAC103 T-Networks, this new module is also inspired by Twin T-Networks circuits used in many lengendary drum machines. A simple 4 voice module with frequency controls for each of the voices. This new module also features CV inputs with attenuverters for each voice Frequency. Due to the specificities of the circuit, and to keep the module at a low price, these inputs are not callibrated to 1v/octave.

At each voice input there's a gate to trigger converter so any input source is possible.
Audio inputs can also be used as an input, in this case and due to the nature of the gate to trigger converter, each voice can be used as very destructive filters.

The top 2 channels feature a higher frequency range, the bottom 2 channels feature a lower frequency range.

Notes: Jomox's legendary analogue kick drum prowess distilled into Eurorack form. Hugely versatile sound with plenty of CV control on the front panel, plus MIDI via DIN sockets hidden round the back.

Notes: Reverse-engineered from the original machine, the BD909 is an identical recreation of the original all-analogue drum circuit of the TR-909. Tiptop have added additional controls and synthesis features that turn this classic circuit into a chest-pounding analog bass drum laboratory - all tightly packed into an 8HP module. The BD909 sound differs from the BD808 in that the main sonic energy is centered in the mid to low frequency range (as opposed to the low frequency range of the BD808). This frequency range gives the needed headroom allowing your bass lines to deeply fill up the low end while the kick drum rides on top - creating a clear and punchy mix.

The BD909 includes all the controls found in the original: Attack, Decay, Tune Decay, Accent, and Level. Tiptop have gone beyond that and added controls that further increase the palette of sound this circuit is capable of. First off, a tuning control knob has been added for the oscillator and included its own CV input and attenuator that let you tune the 909 kick with your bass lines. Next, control knobs have been added for the tuning attack and extending tuning decay. Each one affects the other, allowing for intuitive and interactive sound shaping, opening Z8000 up numerous "sweet spots" and provides the ability to center the energy peak at different parts of the sound. Finally, Tiptop have offered additional punch and distortion by giving complete control over the internal waveshaper, which allows you to overload the waveform manually or with voltage control.

Beginning with the classic and pure sound of the 909 kick, these additional functions greatly expand the BD909's flexibility and let it create powerful analogue bass drums that range from soft and smooth to punchy and aggressive - and everything in between.

Notes: Module A-199 is a spring reverb module. The reverb effect is electronically simulated by means of 3 spiral springs. Spring reverb systems have a very characteristic sound that is based on the (insufficient) mechanical properties of the springs like signal delays, audio resonances, limited frequency range, acoustic feedback behaviour, sensitivity to mechanical shocks and others.

The 3-spring system used in the A-199 ensures a "dense" reverb because of the different properties of the three springs.

The A-199 implies some special features that are not self-evident for spring reverb units:

The reverb signal can be fed back to the input using the Feedback control. Even self-oscillation of the springs similar to the self-oscillation of filters is available. The feedback loop can lead even via external modules like VCA, VCF, phaser, frequency shifter, vocoder, distortion/waveshaper, ring modulator and others. In this case the reverb output of the A-199 is connected to the input of the external module(s) and the output of the external module(s) is fed back to the Ext. Feedback In socket of the A-199. This socket contains a switch that interrupts the internal feedback loop as soon as a plug is inserted.

Another feature is the Emphasis control. This enables the adjustment of the accentuation of middle frequencies (around ~ 2kHz).

With the Mix control the relation between original and reverb signal appearing at the mix output is adjusted.

Using all these features very extreme and unusual effects can be generated with the A-199.

Notes: The Low Fat is a new 2hp Eurorack module by AJH Synth, it's a High Pass filter, with frequency control by either manual pot, and/or external CV with attenuator. It's intended to compliment other filters, particularly low pass VCF modules, in practical tasks such as removing excessive low frequencies, for example when the bass is swamping a mix. It can be switched between 6dB (1 pole) response and 12dB (2 pole) response.

By patching a CV signal to the FCV input it can be voltage-controlled and used musically as with any other VCF. When used in conjunction with a LP filter it forms a fully customisable band pass filter, allowing the range of passbands to be cherry-picked. Feeding in a 1V/Oct pitch CV and setting the FCV pot to a suitable level allows it to track an incoming pitch CV, so the amount of High Pass filtering remains constant as the pitch of the incoming VCOs traverse up and down the frequency range. This can be particularly useful in creating percussive sounds, such as snares and hats, but also on sequenced bass lines. Since it is only 2HP it's a great way to occupy one of those frustrating gaps in your eurorack modular case with something that is deceptively useful, and adds another dimension to the classic bass monster that is the Transistor Ladder Filter.

Notes: Clock generation meets waveform manipulation in this analogue harmonic oscillator. Combine with the Tobinski sequencer and/or interpolating scanner modules for the best creative results.

Supplier's Notes:
The Harmonic Timing Generator is a versatile Eurorack module that combines advanced clock generation with harmonic waveform manipulation. Combined with the Tobinski Sequencer, the module is a great tool for rhythmic and sonic creativity in the modular system.

As a reference clock generator, the Harmonic Timing Generator produces a base frequency with analogue multipliers (x1 to x8) to generate complex timing signals. Three selectors provide manual or voltage-controlled frequency switching, offering flexibility for intricate sequencing patterns. An LFO mode enables slower clocking rates, ideal for driving sequencers or generating modulation sources.

When used with the Interpolating Scanner, the sawtooth outputs of the Harmonic Timing Generator are transformed into sine waves. This allows the module to function as a harmonic oscillator at audio rates or as a versatile modulation source in LFO mode. Its dual functionality ensures that it can adapt to a wide range of patching needs, from rhythm generation to rich harmonic exploration.

The Harmonic Timing Generator is a versatile and creative tool, offering rhythmic and harmonic possibilities that complement any modular synthesizer setup. Its integration with other Tobinski modules ensures a cohesive and expansive sonic palette.

Notes: Introducing the CYMBL909, part of Tiptop's new series of drum modules that brings those classic percussion sounds into the modular synth world, instantly turning your system into a self-contained music machine.

CYMBL909 is a dual voice module containing the TR-909's original Crash and Ride circuits adapted for use in Eurorack modular synthesizer format and was designed to sound like a fresh machine coming out of the assembly line back in the 80's. On top of the original, Tiptop have added some great new features that expand the sound palette of what can be produced with these two voice circuits.

The original circuits use a combination of low-fi 6-bit sound samples that pass through a series of analogue elements that provide envelope and filtering to the source sound. The CYMBL909 module adds manual and voltage control of the sample's analogue tuning section creating tones which range from heavy industrial at the low end, to the original crash/ride sound at the mid range, and bright hats-like sounds at the top end. Modulating the tune with an envelope, CV sequencer, or LFO makes interesting sound bending effects, which can be applied either in or out of sync with the triggering of the sounds.

Just like the other drums in this series, the CYMBL909 high-powered output gain stage allows you to further enhance the sound through distortion and clipping. Tiptop have designed a dual pulse-shaper circuit on each gate input so you can trigger your CYMBL909 with trigger/gate signals from step sequencers, clock dividers or any other pulse/clock.

Notes: Introducing the TOMS909, the warmth of the classic, all-analogue, punchy tom-toms from the TR-909 drum machine. The TOMS909 contains all three of the TR-909's original LOW, MID and HIGH tom-tom circuits adapted for use in the modular format. The module was designed to sound like a fresh machine coming off the assembly line back in the 80's. To add flavour to the beast, Tiptop have extended each tom's tuning range so it's easier to dial soft bass drums on the low end and high-pitched toms on the other.

The toms circuitry is made up of 9 triangle oscillators and a stack of filters, VCAs, and envelopes which, in total, took about half of the space on the original 909's circuit board. Utilizing the latest in electronic design technology, Tiptop have managed to squeeze this enormous circuit, consisting of more than 450 components, into an area only 16HP wide. It is a beautiful board with hundreds of tiny, shiny components: it's a little analogue jewel.

Each tom includes a trigger and accent input with accent level control, manual tune, voltage-control tune input with attenuator and independent audio out. In addition, a MIX out is available that sums all three toms together as well as access to the MIXZ MixBus on the back. On each gate input, Tiptop have designed a dual pulse-shaper circuit so you can trigger your TOMS909 with trigger/gate signals from sequencers or any other pulse/clock sources.

Notes: Warp is a novel synth engine that combines the best of additive and wavetable synthesis.

In the center of Warp's control panel is a colorful XY LED matrix that represents the sound space from which Warp draws its sounds. This XY sound space consists of 32x16 frequency spectra. Each of Warp's four voices can move freely and independently across the XY space. It always uses the surrounding frequency spectra to calculate a wavetable based on 512 sine waves in real time using additive synthesis. By changing the position, wicked wavetable sounds are possible, playable with four voices and eight oscillators and navigable in two directions. An intuitive integrated editor allows playful modeling of your own frequency spectra.
With Warp's SPEC effects the frequency spectrum can be filtered and deformed in realtime before a wavetable is calculated. The wavetable can then be modified with WARP effects like wavefolder, PWM bend, overdrive and redux. The resulting wavetable serves as source for two oscillators per voice, which can be detuned and also synchronized to each other. Each voice is followed by a 12/24dB/octave high pass and low pass filter.

Warp offers an integrated editor, with which you can playfully draw and modify your own frequency spectra. The XY-Sound Space is seen as a canvas on which you can draw your own frequency peaks. Several drawing algorithms are available as tools to edit single or a group of harmonics in a musically meaningful way. There is also the possibility to derive frequency spectra from audio samples from the SD card or to put whole wavetable audio files into the XY sound space. Likewise, the XY sound space can be exported to the SD card as a wavetable audio file of any length and bit depth, so Warp can also be used as an intuitive wavetable generator for other synthesizers.

Also on board are two internal ADSR envelopes and two LFOs, which can be routed to a variety of internal destinations using a modulation matrix. To keep the overview, all modulations are color-coded and are additionally visualized by pulsating LEDs in the modulation matrix view.

Navigation through the menu is as intuitive as with our QUASAR module and is simply done via a push-encoder and a back button. The display always shows which function the four surrounding aluminum encoders currently have, and colored LEDs next to the encoders provide visual assistance. Likewise, the tuning of the module is done via a detented encoder, which adjusts the pitch either in fine steps, in semitones or in octaves. An octave switch is thus already integrated.

For all its feature-richness, Warp still remains a playable and performance-oriented instrument. The large potentiometers serve as macro controls to control several parameters under the hood at once. This keeps the instrument straight forward with a manageable number of controls, but they are all very expressive.
Likewise, the module offers the ability to save and load presets and also comes with audio files and presets on board. Thus, Warp is ideally suited for both detail-oriented sound design and hands-on performance.

In the standalone version, Warp is a monophonic four-voice synth voice that can also be used as an oscillator. With an expander module, it will also be possible to play Warp four-voice polyphonic via MIDI and CV/Gate in the future.

Warp uses a novel hybrid engine that combines the best of additive and wavetable synthesis. With the integrated editor you can playfully draw your own frequency spectra like on a canvas into the colorful XY sound palette. Warp is a feature-rich powerhouse that lets you create all kinds of sounds, from glassy clean to crunchy crunch. Thanks to expressive macro tone controls, extreme morphs are possible in a single pot turn.

Notes: Arkan

Dual Voltage Polarizer

You may have heard this before: "You can never have enough VCAs". A voltage polarizer (also known as a bipolar VCA or a 4-quadrant multiplier) is often viewed as the VCA better suited for CV. As it can be used as a unipolar VCA and it allows you to invert a signal when it is modulated with a negative voltage. Resulting in interesting movements in your modulations.

What sets Arkan apart from other voltage polarizers is the curvature control, a feature usually only seen in unipolar VCAs. By taking a different approach to the classic voltage polarizer circuitry, Malstrom have devised a unique solution that provides a new way to shape your audio and CV. The non-linearity of the polarizer also makes Arkan really good at reaching silence when presented with a 0V CV signal.

At audio rate, Arkan acts as a ring-modulator with four controls to change timbres.

Boosting adds odd harmonics (symmetrical distortion), while offsetting adds even harmonics (asymmetrical distortion). The modulation curve changes ring modulation sharpness, and modulation strength determines the carrier dominance.

Two identical channels with carefully selected features will make Arkan your go-to modulation control hub. Arkan is especially useful for common utility duties such as mixing, scaling, inverting and offsetting. As well as CV modulation, feedback patching, and waveshaping. All this makes Arkan a very versatile tool that will certainly have a place in your patch!

Features (per channel)

- Input attenuation with inverter switch gives you more precision and range, with voltage inversion and quick silencing.
- Bias input with attenuverter control to offset your input signal or mix/invert another signal.
- CV input with curvature control allows you to shape the polarizer and improve its 0V attenuation.
- CV modulation control to fade in the modulator, allowing you to determine the amount of modulation.
- Voltage gain and polarity led indicators showing you exactly what is happening under the radar.
- Output normalled internally and externally (to other Arkans) to easily mix signals.

Additional features

Optional signal boost (x4 / +12dB) via switch on the PCB to increase voltages when needed.
5V or 10V voltage reference selection for bias voltage and CV input range to adjust Arkan to your system.

Notes: MIXZ is a multi-channel mixing module for mixing audio, CV, and gate signals with excellent linear response and low noise. Balancing a clear visual layout and multiple mixers in a small footprint makes the MIXZ easy to use in a variety of configurations within a modular synth. Its high-quality analog mixing circuitry makes for a great sounding mixer with plenty of headroom, providing a smooth, organic merge of dynamics and excellent separation of mixing sections and channels. MIXZ has three sections:

Mixer A: a low-noise, 4-channel mixer with independent gain control for each channel.
Mixer B: a low- noise, 4-channel mixer with master gain control.
MixBus: a multi-channel mixer that mixes signals from modules utilizing the Tiptop MixBus.

Mixer A and B can be configured as either two independent, 4-channel mixers or as a single 8-channel mixer. If the output of Mixer A is not in use, then Mixer A will be routed internally to Mixer B forming the 8-channel mixer.

Tiptop MixBus is a new method we have developed to mix audio signals through the Eurorack power bus board without patch cables. A little bit of magic, eh? Although this technique is not ideal for a low-noise mix, we found it to be useful for some applications, including mixing our drum modules, which all have a MixBus-enabled output. The result is that your drum modules are always available and mixed on the master out of the MIXZ with a flip of a switch. This will save you time and frees up cables for repatching sound again and again, while keeping the channels of MIXZ free to bring other signals into the mix.

Combining the MixBus with Mixer A and B, the MIXZ sums dozens of channels in only 10HP.

Notes: A unique analogue take on granular synthesis, inspired by Yannis Xenakis, the Grainity pairs a granular filter with a multimode filter to create new textures and harmonics.

Supplier's Notes:
The Grainity brings a unique and never-heard-before concept to the world of analogue VCF.

While being based on analogue filtering only, the Grainity expands and enriches the sound in creating subharmonics, harmonies, unison, flanging effects and formant filtering all at once.

The module presents two sections, the granular filter itself and a typical multimode filter, each with its own output.

A third output offers a mix of both filter paths. Numerous controls and CV allow a very wide palette of results.

What is the Grainity

Granular?

The word granular was chosen for this filter module in relation to the concept invented by the composer Yannis Xenakis, and which is described as assembling small chops of sounds - he called grains - according to a pattern.

This is exactly what the Grainity does, no more no less ... but, digital control allows doing it in ways that are decades away from what tape and scissors allowed at the time.

Technology wise ...

In the granular section, the incoming sound cycle is determined in order to step through various filtering and phase variations of itself according to predefined patterns called structures.

The controls allow alterations to the cycling phase, cycling frequency offset (tuning), structure selection and frequency division of the filters cycling. This comes in addition to the usual filter frequency and resonance controls.

What the Grainity is not

Technology wise ...

Despite relying on a microprocessor, the Grainity is not a digital audio processor. At any time, the sound remains in the analog domain and goes through analog circuits from in to out.
The digital processor does not convert or generate audio signals; it is there to control the analog circuitry and manage the interface and display.

Sound wise ...

Several digital modules offering granular processing rely on the layering of sound grains, which leads to blurry and cloudy textures.
Layering of the grains is a late addition to the concept of granular synthesis and is not a mandatory feature of the concept.
The Grainity does not use delay lines or sampling memory but is nevertheless true to the foundations of the granular synthesis concept.

The granular VCF in the Grainity is unconventional in that, most of times, it is not filtering the sound in the common expectation of removing something. Typically, the granular process adds more than it removes by expanding both the lower range, creating subharmonics, and the upper harmonic contents in multiples ways.

Notes: A multi-purpose module designed to combine noise and modulation sources, slew, sample-and-hold, envelope following and more. Extremely versatile way to add randomness and controlled movement to patches.

Supplier's Notes:
Flurry collects and connects a number of practical modular synthesis tools, focused on clocks, noises, and randomness to create a module that is rife with opportunities for exploration and experimentation. Equally capable as a synthesis source, modulator, clock, or signal modifier; It is bound to find a way to bring new life and dimensions to your synth patches.

Core Functions:

A clock and random pulse source with adjustable and modulatable rate
Accurate pink and white noise sources
Analogue sample & hold and track & hold circuits with very low droop
Analogue slew with adjustable slew time and edge selection (rising edge, falling edge, or both)
Envelope follower
16 noise synthesis algorithms, each with 2 parameters.

One of Flurry's more interesting aspects is its collection of digital noises, which provide a wealth of interesting noises, suitable for either audio or modulation purposes. Each noise type has its own pair of unique parameters to further dial in the desired characteristics, with the primary parameter under CV control.

Most people consider noise to be "undesirable," and product developers expend great effort to design circuits that minimize noise. So why make a module designed specifically to create noise?

Indeed, unwanted noise is undesirable. But not all noise is unwanted. Synthesizing the sound of wind or waves are a couple of the more obvious uses for a noise generator, but the possibilities go far beyond. The crack of a snare hit; the breathiness of a flute sound; an added sizzle to a resonant pad - all are within the sonic domain of noise.

But noise has many other benefits beyond simply being heard. Noise happens to make a wonderful modulator. When noise is used to modulate a filter's cutoff frequency, or an oscillator's pitch or pulse width, then all sorts of raspy, buzzy, gritty timbres are obtained.

Noise is also a key ingredient in sample & hold circuits - a technique most commonly used to generate stepped, random voltages. The circuit works by sampling an input signal's voltage each time you send it a clock pulse, and holding that voltage until the next clock pulse. So, naturally, Flurry also contains the requisite clocking tools! Two of the most common destinations for the S&H output are a filter's cutoff frequency (creating stepped, clocked timbral changes), and oscillator pitch (which produces random notes at clocked intervals).
Of course, you might not always want your voltages to change so abruptly at each clock pulse. Maybe you'd prefer they wobble about gradually and with more grace? To do that, you need a slew circuit, and once again Flurry has you covered - allowing you to select not just the slew time, but also whether the slew is applied to rising voltages, falling voltages, or both. A flick of the switch, and that Slew circuit becomes an envelope follower, enabling Flurry to generate envelopes from input signals (syncing to drum hits are a common use).

With all these features, plus the ability to create random pulses, clock to external pulses, and perform more esoteric track & hold duties, Flurry is a noise lover's toolbox.

Notes: Two fuzz channels based on the fuzz face circuit with a built-in pickup simulator.

Gnarly is a 7 knob beast that will destroy whatever you throw at it. It has many dead zones in the pots that will adjust based on the position of other pots. It's all about finding the sweet spots and living on those fine edges. The transistor pairs on this section are replaceable.

Oomph is a 5 knob bass friendly take on the fuzz face and compliments the upper harmonics of the Gnarly section.

Pickup simulator - Fuzz circuits offer unique sound when paired with the inductance of the pickup coils in a guitar. This why it is often suggested to have fuzz pedals as your first in a pedal chain. So After Later built-in a coil to simulate your eurorack signal being emitted by a guitar pickup. After Later also included a pickup simulator output so you can use it to interface with other fuzz instruments (pedals, modules, etc.).

As an added oddness - you can also input your guitar into the pickup sim output (just don't plug anything into the normal input). This will still get you Eurorack level output. Please don't input Eurorack levels into the pickup sim output.

Tips - Experiment with the pickup simulator and buffered signal. Use the PS.Level to keep the signal low, borderline on cutting out. You find lots of joy in the gnarly section by keeping this level at the edge.

Notes: 8 channels of audio or modulation over ethernet. There are two modules and a 3' CAT7e cable to connect them together. There are 8 total channels that are unbuffered and bi-directional. The primary usage is to connect two cases or just send a bundle of signals from one part of your larger case to another. You also get the option of buffering up to four channels on each side. This gives you a local copy of the signal and sends buffered copy to the other module, saving you from having to use a MULT to keep a local copy.

Some notes:

When one side of the Light Rail is in buffered mode, you cannot send signals from the opposite side on those 4 buffered channels (the other 4 channels can still be used in bi-directional mode)

If you are after a different longer/shorter cable, you will get the best performance with CAT7e as it offers the shielding, which is used for the ground.

While the cross channel bleed is minimal, you will notice some very minor cross talk between the channels.

Notes: Discover the flexibility in your sound design with our ultra-compact 2HP wide Sync LFO (Low-Frequency Oscillator) in Eurorack format. Designed for musicians looking for versatile modulation in their Eurorack system, this LFO delivers a wide range of possibilities to make your soundscapes dynamic. Despite its small size, this Sync LFO offers a wide range of features to help you reach your creative potential.

Notes: The Flexshaper is a highly versatile module when it comes to modify evolving voltages in other directions and levels.

Five settings allow you to fold/expand/clip/compress/invert partially or completely any CV or audio signal.

The module can act as an envelope-shaping tool, frequency multiplier, waveshaper, clipper, distortion, limiter, curve changer, and more.

Five CV inputs offer limitless control over the placement of the voltage points for dynamic signal sculpting.

Birth of the product

The idea of the Flexshaper comes from a feature in the Oberheimr Matrix synthesizers called Tracking Generator.

This signal processor was part of the modulation matrix and meant to be virtually inserted between modulation sources and destinations in order to change the shape of the controlling signal.

The Flexshaper applies the same concept using the same 5 shaping points. However, it goes beyond Oberheim's implementation on two main aspects:

It goes fast enough to process signals at full audio rate
The 5 points are dynamically adjustable (CV) in real-time
Besides, the Flexshaper can process adequately bipolar and unipolar Eurorack signals, even changing them one another.

Notes: Proper creative stuff with this one. Lush, characterful stereo reverb with CV control, distortion, pitchshifting, a freeze button and more. Oh, and it's got user-customisable DSP firmware for good measure.

Supplier's Notes:
Desmodus Versio is Noise Engineering's take on a synthetic-tail generator reverb. In only 10hp, it features true stereo in and out, seven CV-controlled parameters, and three reverb modes. Desmodus Versio's feedback control sets the length of reverberation, from short echoes through infinite regenerations.

At its max, the reverb ducks when it receives input, useful for creating sidechain ducking and atmospheres for percussion. The different reverb modes offer even more sound options with clean, distorted, and pitch-shifting shimmer settings. The FSU button acts as a freeze and also creates some noise to stimulate the reverb when there is no external input.

Desmodus Versio isn't just a reverb, though: it's a DSP platform. Its firmware can be changed via USB, so users can load future firmwares onto it or develop their own with upcoming open-source support.

With Desmodus Versio, Noise Engineering continues their tradition of supporting conservation:a portion of proceeds from every Desmodus Versio sold goes to Bat Conservation International. Find out why bats are not only cool but also an important part of our ecosystem at Bat Conservation International's website, batcon.org.

Notes: The Ultimate Eurorack Utility Module (and a whole lot more!)

The DATA is a digital platform for testing, measurement, and signal generation in Eurorack modular synthesis systems. It is a modular tool kit, with functions applicable to any system and style.

Use the DATA's scope to view the interactions between your control voltages and audio signals, allowing you to master your modules by understanding their voltage ranges, control shapes, and parameter responses. Use the DATA's dual waveform generator to dial in a precisely scaled LFO for CV control, or use the waveform's frequency "note mode" to effortlessly make dyads (two note chords). Use the DATA's clock program as a master clock or to divide or multiply an incoming clock signal, sending four different clock outs to gate modules directly or as control to sequencers.

The possibilities of the DATA are basically unlimited; with the included microSD you can update the DATA's firmware and we can continue to refine and create new programs.

Notes: Complex digital oscillator with unison detune, programmable 3x4 modulation matrix mixer and external input. Intricate arrangements of phase distortion, thru-zero frequency modulation, and complex oscillation are instantly morphable and recallable through a voltage-controlled preset manager. Suitable for genre-targeted sequenced basslines, synthesis of stone, glass, and steel tones, and simulation of the acoustic properties of industrial machinery.

The Hertz Donut Mark III's main oscillator shapes its timbre by distorting the phase of a waveform lookup ramp, offering a linear growth of brass overtones from a simple sine wave whilst performing with exceptional clarity under heavy frequency modulation. The simulated resonance peak familiar to enthusiasts of phase distortion is also present and continuously controllable. The beloved "fractal" distortion from previous iterations of Hertz Donut is simultaneously available. The three waveform parameters operate in a modeless timbre space fully morphable under preset and shared manual/CV control, exhibiting stunning spectral evolutions that are intensified through the module's internal modulation bus. The fold knob is assignable to control one of the three parameters at a time, with the CV input also assignable to any of the three.

Two sinusoidal modulation operators are mixed to four modulation destinations with an external audio input. The operators may be locked to several precise frequency ratios of the main oscillator, or set to be otherwise subordinate. The three sources may modulate each other's frequencies, or the amount of phase or fractal distortion. A plethora of control voltage inputs allow full control of the patch, reacting within a +/- 10V range. The first operator has a calibrated 1v/oct control voltage input and fine tune control, for use as an independent oscillator augmented by the modulation bus. The modulation mix is placed under the influence of a master control, so that a single knob and CV input control the degree of modulation in the entire module. Each sound that you design will have a unique and intense behavior of this modulation control.

The preset manager stores 8 entire panel/menu states for instant recall under manual or voltage control. The control can also cause the creation of elegantly randomized preset data. The preset manager can be placed into a morphing mode where it assumes control of the various parameters, smoothly fading between entire panel states and generating very complicated sounds that are not easily described.

The unison detune function mixes in a nearly identical copy of the sound with slightly offset frequency, or optionally in octave or fifth intervals. The Hertz Donut operates at 96khz for a minimum of sampling byproducts, able to consistently and competently generate ornate digital beauty and jagged swaths of sonic mayhem. The auxiliary output presents the output of one or both modulation operators, also with optional unison applied. The nearby mix output is an analog sum of the Main and Aux outputs, facilitating parallel FM algorithm construction. Perfect, genuine, complete, crystalline, pure.
