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

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

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

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

Notes: MMF is an analogue, multimode filter with a 12dB per octave slope. Its sonic character swings all the way from classic low pass to squelchy acid lines. Simultaneous outputs of low pass, high pass, and band pass filter types are provided allowing for many variations of the input signal. Whether you're looking for smooth and creamy, or resonant and wild, MMF can go there.

Notes: Seriously potent polyphonic voice built around 16 sine-based oscillators. Capable of a huge range of tones thanks to FM, phase distortion and wavefolding. Another cracker from a consistently reliable brand.

Supplier's notes:
The Ensemble Oscillator is a unified polyphonic voice of sixteen complex oscillators combining additive, FM, phase-distortion and wavefolding synthesis techniques in new unorthodox ways. By quantizing the oscillators to scales or series of harmonics, the Ensemble Oscillator allows you to explore the sonic boundary between musical chords and rich evolving textures. Easily create a wide variety of sounds ranging from aggregates of pure sine waves to pulsar synthesis or pristine harmonic tones and lush wide chords to rich dirty drones and rumbling glitches. Custom scales can quickly be "learned" and saved using a CV keyboard or by manually entering notes with the controls.

The Ensemble Oscillator is designed by Matthias Puech and 4ms Company.

30 factory-programmed, user-writeable scales organized in three groups:
12TET: all notes quantized to equal temperament, repeating over octaves
Octave: unquantized notes, repeating over octaves
Free: unquantized notes, repeating over the interval between the lowest and highest note

Notes: 2xSAM is 4 HP Dual Stereo Attenuator-Mixer

Several 2xSAMs can be chained together or with other HN stereo modules via sockets on the back side.

Notes: Performance oriented Sample Drum brings you two independent drum sounds or loops with plenty of manual and CV controlled parameters. Samples are stored on the microSD card, and OLED screen makes working with samples instant and easy.

Sample Drum allows you to slice up loops directly in your modular system and rearrange them to taste. For processing, there are tuning functions (including 1 v/octave pitch tracking) and virtual VCAs plus AD envelopes. Thanks to the module's dual-channel concept, two loops can be combined. It is also possible to load one-shot samples instead of entire rhythms, of course. A total of six CV inputs guarantees lively results.

Sample Drum is composed of two identical audio players. WAV files (including cue points) are fed to the module via a micro SD card. Loops can be cut into several sections using the Data, Start and End potentiometers. The resulting slices may be played back in any order imaginable. A tune control allows real-time pitch changes. Additionally, there is a virtual VCA plus AD envelope per slice. - But that's not all! There are three CV inputs per channel, which can be routed to any parameters. It is even possible to play sounds according to the 1 v / octave standard. Results are emitted via one output per player.

Notes: Back in 2008, the original Z5000 was not only the world's first Eurorack DSP effects module but also the first Tiptop Audio module released. It brought voltage controlled digital effects to Eurorack for the first time and the Z5000 was eventually replaced by the Z-DSP open source platform. Now, years later with over a decade of experience developing audio effects for Eurorack signals we are introducing a totally new version of the Z5000: a compact stereo 8HP multi effect with voltage controlled parameters, VC analogue clock generator driving the DSP chip and 24 of our creme de la creme reverbs, delays, modulation, harmonization and pitch modulated effects. A number of programs in the Z5000 combine more than one effect, in series or parallel, that represent studio techniques from-the early days till modern times often leaning toward the more experimental side.

Notes: Compact and simple four-input mixer module from Uncle Dieter. Linear pots make it suited to mixing CV signals but it can also handle audio. Mixed signal hard-wired to two sockets.

Supplier notes:
Module A-138n is a simple four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator available. The output is twice available (two sockets, hard-wired like a multiple).

HP : 4

Notes: The module contains two ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor) behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V (10V = attack peak).

The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.

Notes: Row Power is a clean, regulated, and protected power solution for eurorack systems. Row Power 35 provides 35W of power, suited for any typical eurorack row (84HP to 168HP):

+12V @ 1.4A
-12V @ 1.25A
+5V @ 1.0A

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying-bus cables or the Bus Stick.

Daisy-chain multiple Row Powers to use a single power brick for multiple rows (typically 3-5 rows per power brick). Each row will be independently regulated and protected for ultra-low cross-talk between rows. Rows can also be hot-swapped (plugged/unplugged without powering the whole system down).

Notes: Clep Diaz is a handy and small step CV and LFO generator. In step and random modes, use the encoder to control the number of steps in the sequence; in LFO mode, the encoder controls the amplitude of the wave. Toggle the directionality of the sequence: up, down, or up/down to customize the CVs further. CD also gives CV control over the number of steps in the sequence and an end-of-cycle trigger output. Unipolar and bipolar outputs allow maximal control.

Notes: Module A-150-8 contains eight manually/voltage controlled switches. Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2). The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. Two LEDs show which in / output is active (i.e. which is connected to the common out / input). In addition, the LEDs are used for the programming of the module:

For each unit the operating mode can be selected: Toggle or Level controlled. In Toggle mode the rising edge of the CV input or operating the manual control button changes the state of the switch. In Level mode the switch state is defined by the voltage applied to the CV input (low voltage = I/O1, high voltage = I/O2) or by the state of the manual control button (not pressed = I/O1, pressed = I/O2). The modes are programmed very easily: Operating the Toggle/Level button of the program section displays the current state of each switch with the LEDs: left LED on = Toggle mode, right LED on = Level mode. Operating the manual control button of the switch in question changes the toggle/level mode while the Toggle/Level button of the program section is operated. During the programming patched CV signals may have to be removed as the CV signals would interfere with the manual operating buttons during the programming process.

In addition, it's possible to define master/slave groups. In such a group the upper unit (= master) controls also the state of the following switches provided that they are defined as slaves. Master/slave programming is also very simple: Operating the Master/Slave button of the program section displays the current state of each switch with the LEDs: left LED on = Master, right LED on = Slave.

When all 8 units are defined as master all switches are independent from each other. If for example the sequence is MSSSMSMS the control unit of the first switch also controls the switches 2, 3 and 4. The control unit of switch 5 also controls the switch 6, and the control unit of switch 7 also controls the switch 8. The current states of the slave switches are overwritten by the state of the master switch.

Technical note: To protect the electronic switches in case of an unsuitable patch (e.g. connection of two outputs) a 1k protection resistor is inserted into the O/I line of each switch. If control voltages used for VCOs are switched this may cause a small voltage drop and lead to undesired audible detuning. For this application we recommend to insert a CV buffer between A-150-8 and the VCO(s), e.g. the Buffered Multiple A-180-3 or the Precision Adder A-185-2. Integrating the buffers into the module A-150-8 was not possible because this would ruin the bidirectionality of the switches.

Notes: Module A-148 (Dual S&H) has two identical sample & hold modules, designed to produce 'staircase' voltages. The signal present at the sample input is sampled at a rate set by the signal at the trigger input, and held at that voltage at the S&H output.

The exact shape of the staircase depends on the sort of waveform at the sample input: NOISE or RANDOM signals produce random patterns; an LFO produces rising or falling staircase patterns.

Two LEDs for each S&H indicate the voltage (positive or negative) of the sampled signal.

Notes: The 333 is a summing and distribution module for Eurorack modular systems.

It is composed of three identical sections, the red, yellow and green, each of those featuring three inputs summing amplifier with three independently buffered outputs.

Derived directly from the CGM creative mixer series, the sum section is DC coupled, allowing the sum of control voltages as well as audio signals.

With an extremely low tolerance in both sum and output sections, it is suitable also for summing quantized voltages like the ones coming out from the quantized outputs of the SAPEL.

In case CVs or audio signals are particularly hot, the 6dB attenuator might be helpful to reduce exactly by 50% the incoming signals.

Red and yellow output are also normalled to the 1st jack socket of the yellow and green input: in this way this module can also work as a 1 to 9 buffered multiple.

Notes: This is the third generation of Intellijel's much loved Korgasmatron filter designed in collaboration with David G. Dixon. The Morgasmatron features two completely independent six-mode filters (labelled "A" and "B") - each with its own mode-select knob, input, output, cutoff, resonance, Q-drive and gain control. Each filter has a pair of CV inputs (one with a built-in attenuator and the other with a built-in attenuverter) for modulating cut-off, and another CV input for modulating resonance. Both filters self-oscillate at maximum Q, and produce pitched sine waves that track the two separate 1V/OCT inputs.

You can use the two filters independently of one another, or you can use them together (in either a series or parallel connection) and smoothly crossfade between them using either the XFADE knob or the XFADE CV input and built-in attenuverter. You can flip the DRY switches to instantly bypass either or both filters; invert the phase of Filter B; or overdrive Filter A by switching on the new Overdrive circuit. A MIX output provides (as you might suspect) a mixed output of the two filters.

Notes: Terci Ruina combines three classic distortions in 4 hp. Distortions are reinterpreted in classic NE style and routed through each other for complete sonic annihilation of any sound. Patch in and out anywhere in the signal chain to pick the best sound for your purpose (because modular). Looking for a pretty distortion? This is probably not your module. Unapologetically gross and dirty.

Notes: Rossum Electro-Music Software Architect Bob Bliss (who also, as it happens, fathered E-mu's famed "EOS" Emulator Operating System) has created Panharmonium, a unique music and sound design tool that analyses the spectral content of any audio signal and uses that analysis to drive a bank of from 1 to 33 oscillators. Depending on various control settings, Panharmonium can accurately reproduce the input spectrum in real time or modify it in a multitude of wildly creative ways. All with an interface whose immediacy encourages performance and interaction.

Panharmonium input can be anything from a single oscillator to an entire mix (including vocals). From dense, swirling pads and drones that evolve with the input's changing spectrum, to clock-syncable spectral arpeggiation, to as-yet unnamed harmonic effects, Panharmonium opens up an entirely new world of sonic possibilities.

Additionally, Panharmonium can take a snapshot of an instantaneous spectrum and use that as a complex harmonic oscillator, which can then be modified and modulated by all of Panharmonium's other controls.

Panharmonium accomplishes its magic though a combination of functional submodules:

Spectral Analyser:

The Spectral Analyser provides tools for defining the analysis process.

- The Slice parameter sets the rate at which the incoming audio is transformed to spectral data. It can be set by the Slice and Multiplier controls, the Tap button, or by an external clock signal. Very short slice times result in real-time spectral data, while longer times can create rhythmic spectral patterns.
- The Centre Freq and Bandwidth controls (and associated CV inputs and attenuverters) control the range of frequencies to be analysed. The Bandwidth control allows the selection of narrow to wide pass bands on the left side of the pot and narrow to wide notches on the right side of the pot. The ability to sweep the frequency and modify the bandwidth under CV control opens up a wide range of sonic effects.
- The Freeze button lets you freeze the spectral integrator, sustaining the currently analysed spectrum.

Spectral Modifiers:

These controls allow you to creatively modify the analysed spectra.

- The Voice parameter lets you select from 1 to 33 oscillators to resynthesise the spectrum.
- The Blur parameter (and associated CV input) is a spectral lag processor that controls how quickly the spectrum can change.
- The Feedback control (and associated CV input) lets you route the re-synthesised audio back into the entire processing chain for subtle or dramatic feedback effects. At its max, the output becomes self-sustaining, even if the input is removed.

Oscillator Bank:

The Oscillator Bank resynthesises the analysed spectra.

- The Waveform parameter selects the oscillators' waveform. In addition to the usual sine, triangle, sawtooth and pulse waveforms, two special crossfading sine and sawtooth waveforms are included.
- The Freq control lets you tune the oscillators over a +/-7 semitone range. The frequency is further controlled by the 1V/Oct input and the FM input and attenuverter.
- The Octave control, not surprisingly, shifts the pitch of the output by octaves.
- The Glide parameter sets the amount of polyphonic glide (i.e., each oscillator has its own glide circuit).
- The Mix control (and associated CV input) sets the balance between the original input audio and the resynthesised audio.

Optional Functions:

A number of optional functions can be selected by using the Output Mode and Tap buttons.

- Holding the Output Mode button and adjusting the Slice control enables Drums Mode, which optimizes the spectral analysis for drums and other percussive inputs.
- Holding the Output Mode button and adjusting the Centre Freq control allows you to instead set the lower frequency of the analysis range.
- Holding the Output Mode button and adjusting the Freq control enables Spectral Warping. In contrast to conventional frequency adjustment, where the harmonic relationships between the spectral elements are preserved, Spectral Warping shifts the harmonic elements individually, producing a variety of clangourous, swarming textures.
- Holding the Tap button and adjusting the Freq control quantizes the resulting frequency adjustments to semitones.

Spectra Memories and Presets:

Panharmonium provides 12 user Spectra memories and 12 user Presets (in addition to 12 each factory memories).

- The Spectra memories let you store up to 12 frozen slices. When selected, a spectrum (up to 33 oscillators wide!) replaces any live input and can have its pitch controlled by the 1V/Oct input and FM controls.
- A Preset is a snapshot of all of the module settings, along with the value of any CVs present at the moment the preset is saved.

Panharmonium is 26HP wide and 25mm deep.
Power requirements (max): 140mA +12V, 30mA -12V. Reverse polarity protected.

Notes: Module A-145-4 is a simple quad LFO (Low Frequency Oscillator). Not a very "exciting" module, just a bread-and-butter device and a simple demon for work. Virtually in every modular system several LFOs are required for modulation purposes. The module contains four simple LFOs with the waveforms triangle and rectangle. A dual colour LED (red = positive / yellow = negative output voltage) indicates the triangle output of each LFO. The frequency range can be chosen for each LFO individually by means of a jumper between about 50 Hz ... 0.04 Hz (about 20 seconds, jumper removed) and about 2Hz ... 0.002 (about 8 minutes, jumper installed).

The module can be treated as a slimmed version of the quad LFO A-143-3 as it has similar features available. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is less than one third of the A-143-3. The module is primarily planned for applications where only limited space is available. The functional difference compared to the A-143-3 are the missing sawtooth outputs and frequency range switches.

Notes: Four channel voltage controlled Clock Divider/Multiplier with master Tap Tempo. Each channel can be synced to the tap tempo, to the channel above, or to an external clock. Each channel also has a reset jack.

With a Tap Tempo button and five sync'ed clock outputs, the QCD is a versatile head-of-the-chain "Master" clock module, and/or a complex rhythmic pattern generator.

Notes: Full-featured triangle core VCO/LFO

The Dixie II+ is a larger variant of the classic Dixie II. Using the same great triangle core oscillator, it adds a number of features to make it even more versatile with only a modest increase in size. The Dixie II+ makes a great primary oscillator for a modular system, or a great companion the Rubicon.

Notes: The Shifty is essentially a combination of four sample and hold stages, a sequential gate and sequencer controller. This collection of functions allows for some specific and useful utility application.

One of the primary uses for Shifty is to take a monophonic sequence source and route each new note of the sequence to up to four different synthesizer voices in a specific pattern. In this way you can create pseudo polyphonic sequences since each voice can be triggered to play and sustain while the next voice int the sequence gets triggered. Another term for this is hocketing.

The other main application of the Shifty is to function as an Analog Shift Register. In this mode each new gate input received causes the current set of pitches to be shifted to new output locations as a new one is added and the oldest one is replaced. This can be an interesting way to create chords that are up to four stacked notes when used with a pitch sequence source that has a harmonious series of notes (e.g. a pentatonic scale works really well). Even just using two of the outputs will yield very interesting melodic interplay and is an excellent way to make a simple sequence much more complex and interesting.

In a more basic way the Shifty could be used as a simple Sample/Track and Hold module or as a sequential gate.

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

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

Notes: Trim is a 2 channel passive attenuator. It features two individual channels of attenuation.

Notes: Inspirational west coast sounds from one of the masters. Additive oscillator with eight harmonics, direct outputs and powerful CV control to scan, tilt and mix the waveforms.

Supplier's Notes:
For the first time in Eurorack, this oscillator module provides outputs for the first 8 harmonics as sine waves. Also included are triangle, saw, square waves.

A voltage controlled mixer with various methods of address allows the user to scan, tilt and mix the harmonics from both panel and external voltage control. It is built on a discrete, all analog triangle core with an old school discrete transistor exponential converter. It has inputs for linear and exponential FM, the exponential with a reversing attenuator. Of course there's a 1 volt/octave trimmed CV input as well.

Power consumption: 120mA at +12 V and 90mA at -12 V

Notes: The Jumble Henge is a 16 input stereo spectral mixer with a unique patch-based mixing interface in a compact space. Each input has a carefully tuned resonant analog filter and a unique fixed pan value, providing each sound its own space within the mix. There is a Mix control to adjust the depth of the filtering and a clean external stereo input for chaining with another mixer or extra sound source. Jumble Henge is a space efficient solution for creating rich stereo mixes from a number of both mono and stereo sources.

INPUTS
Vertical and horizontal patch position determines a source's spectral and stereo placement in the mix respectively.

Aside from centred inputs, every input sits in its own unique pan position, helping to keep a separation between sounds but building a complete stereo image when combined.

The centre right inputs of the top two rows are normalised to the centre left inputs. - i.e if just a left input is patched it will be effectively panned center.

Towards the highs the panning becomes wider - as the human ear better pinpoints direction at higher frequencies, whereas the lows remain more centred for a tighter, more focused sound.

MIX CONTROL
Mix control for the overall depth of the filters applied to the inputs. Note: a slight volume increase occurs near the centre of the dial.

EXTERNAL INPUT
An additional clean stereo input pair for chaining with another mixer or additional source. Right input normalised to left input to accomodate mono sources.

OUTPUTS
Stereo mix output, the sum of all 16 inputs.

Jumble Henge was designed in collaboration with Worng Electronics and is based on the 'SoundStage'.

The Erica Synths Black Dual ASR EG is a versatile, full analogue voltage controlled looping envelope generator and low frequency oscillator with manually and voltage controlled shape and rate, designed for use in advanced modular systems.

It has two identical parts, each featuring all typical envelope generator controls and bonus features - the end of the cycle output and bi-polar LFO output. When in loop mode the shortest attack and decay settings turn the module into voltage controlled drone oscillator with adjustable waveform (it will not track 1V/oct, though).

Notes: The MCFx2 is ALM's state variable 'MCF' filter made double. It features 2 identical classic analog 3 pole state variable filter cores each with Low, High and Band Pass (or Notch) outputs. Direct and voltage control is provided for both filter cut offs and resonance. Switches allow the filters to function as one, with the 'Feed' switch internally routing audio from one filter to the other in series and the 'Link' switch linking the cut off controls for both filter cores. MCFx2 expands on the great sounding MCF filter to offer both serial and parallel functionality for stereo operation, dual peak, tighter slopes and other complex filtering set ups.

FREQUENCY CONTROLS
Sets the base frequency for the filter cut offs. The v/oct and frequency inputs are added to these.

RESONANCE CONTROL
Sets the level of resonant peaks atop the cut off frequencies. The resonance can get particularly aggressive going into self oscillation with the control past 12 o'clock.

OUTPUTS
Each filter output is 3 pole with an 18dB/oct slope.
Low - low pass filter outputs. Passes frequencies below the cut off.
High - high pass filter outputs. Passes frequencies above the cut off.
BP/Notch - band pass or notch filter outputs. Jumpers on the rear of the module select one or the other for each filter.
Passes frequencies within (BP) or outside (Notch) a narrow region around cut off frequency.

LINK BUTTON
Links the left cut off to parallel control both filters. The right controls will now set the max range of the right core. Both filters will track together when the right cut off is fully clockwise.

FEED BUTTON
Routes the output of the left filter core to the input of the right (unless patched), with the desired output filter type selected via jumper at the rear of the module.

FREQ INPUTS AND ATTENUATORS
Control voltage inputs here are combined with knob offsets to set the final cut off. Attenuversion control allows for both attenuation and inversion of the CV. Expects approx. -5V - 5V input.

RES INPUTS AND ATTENUATORS
Attenuated control voltage inputs here are combined with knob offsets to set the final resonance.
Expects approx. -5V - 5V input.

AUDIO INPUT 'In'
Signal inputs to the filter cores for processing.
Input sources may need to be attenuated, filter will drive from hotter input levels.
The Left input is normalised to the right (unless 'Feed' is enabled).

CopierMaschine is an enhanced version of the original quantising digital emulation of a four stage analogue shift register (ASR).

Harrington 1200 provides basic neo-Riemannian Tonnetz transformations of triadic chords, triggered by the digital (gate/trigger) inputs.

Automatonnetz combines Tonnetz transforms with a "vector" sequencer - it can be both a chord sequencer and a melody sequencer, but not of the usual kind.

Quantermain is a quad pitch quantiser for external voltages, with editable scales; it can do clocked (trigger-driven) quantising, or continuous quantising, with a latency of under 100 microseconds; it also features quad Turing Machines, May-Verhulst logistic maps or byte beats as optional, semi-random, internally generated CV sources.

Meta-Q is a dual-channel quantiser, similar to Quantermain, but also offering scale and note mask sequencing.

Quadraturia is a wavetable quadrature LFO, based on the "Easter egg" in the Mutable Instruments Frames module.

Low-rents is a dual Lorenz and Rossler (strange attractor) modulation generator, partially based on the "Easter egg" in the Mutable Instruments Streams module.

Piqued is a quad voltage-controlled envelope generator, based on envelope generator code from the Mutable Instruments Peaks module, but extending it with voltage control, additional envelope types, including re-triggering (looping) envelopes, additional segment shapes, adjustable trigger delays, and a unique Euclidean "trigger filter" which turns the app into a Euclidean rhythm generator which can output envelopes, not just gate or trigger pulses.

Sequins is a dual-channel step sequencer offering 4 "tracks" of up to 16 steps each; tracks can themselves be sequenced.

Dialectic Ping Pong is a quad bouncing ball envelope generator, based on a hidden mode of the Mutable Instruments Peaks module.

Viznutcracker, sweet! is a quad "byte beat" equation generator, which can be used as an audio source to generate curious but often interesting 8-bit noises and tunes, or which can be clocked by an external source to produce "byte beat" control voltage sequences. "Byte beats" were first described in 2011 by viznut (aka Ville-Matias Heikkila).

Acid Curds is both a chord quantiser (sometimes called a "harmonic quantiser" for external pitch voltages), and a chord progression sequencer.

References is an utility app that outputs specific reference voltages on each channel to help tune or calibrate VCOs and other modules. It also includes a high-precision frequency meter and note tuner, a high-precision BPM (beats per minute) tempo meter, and a closed-loop calibration mode.

Notes: Performance-focussed four-channel attenuverter and offset module, with built-in voltage generator for 0-5v or i5v voltages. Simple but effective.

Supplier's Notes:
Lapsus Os is a four channel attenuator/attenuverter and offset. Designed with performance in mind, each channel can be set to either attenuate or attenuate/invert an incoming signal, adjust offset of an incoming signal, or with nothing patched to its input, generate a 0-5v or i5v offset. Switches on the back of the module invert the fader behavior, allowing for the module to be mounted in either direction, for further customization and ease of use.

Etymology
Lapsus -- from latin lapsus : 'sliding' Os -- from latin os 'bones'
"Translation: Dancing Corpse"

Interface

Faders 1-4: The main controls of LO. The LEDs in the faders show the CV that is being passed through. When in attenuverter mode, the LED will be off at 0, allowing each fader to easily be set near 0.

Offset inputs 1-4 (+): Sending a signal to these inputs adds an offset to the input, controlled by the fader and the mode switch.

Outputs: Each channel has a pair of identical outputs. If nothing is sent to either input of a channel, an offset will be generated and output here, useful for controlling parameters on other modules with a single fader.

Uni/Bi Switches 1-4: In the Unipolar position (left), the corresponding channel attenuates the input signal. In the Bipolar position (right), the upper half of the corresponding channel fader attenuates the input signal, the lower half of the fader inverts and attenuates the signal.

Attenuating/attenuverting inputs 1-4 (x): Sending a signal to these inputs attenuates/attenuverts the signal, depending on the position of the channel fader and switch.

Rear-board switches: Below, in red. Inverts the corresponding channel, allowing for creative mounting in either direction. Note that each channel must be switched independently to fully reverse the functionality.

Patch Tutorial

Patch 1: Set a channel switch to the left position and patch the outputs to CV inputs on another module (for instance, Loquelic Iteritas). The fader becomes an easy-to-use controller for those parameters. Patch the rest of the LO channels to other parameters in your system to create an expressive and intuitive interface.

Patch 2: Patch a CV signal (such as an LFO) into the attenuverting input of a channel. Set the channel switch to the right position, and patch the output to a bipolar CV input in your system. Tweak the fader to attenuvert and dial in the perfect amount of modulation on the fly.

Patch 3: In a case with four voices route each LO channel to the decay control for each voice. Use for centralized control over voicing.

Notes: TRINITY is a 3 channel Digital Drum Synth Array packed into a 20hp eurorack synthesizer. Effectively, Trinity performs as 3 powerful drum voices packaged into one beastly drum module with a few tricks up its sleeve.

The name Trinity refers to the 3 drum channels and tips its hat to the core elements of any modern beat driven composition which is typically Kick, Snare and Hat. Trinity takes this simple idea and flips it on its head with 3 channels and an array of drum synth algorithms that use various types of synthesis (Analog Inspired, Additive, FM & Noise). This allows for a wide range of drum design capability that achieves and reaches far beyond the conventional kick, snare ,and hat.

Trinity's array of digital drum synth algorithms are very malleable by way of the 7 knobs and 4 mini-pots, each of which control a specific parameter and characteristic (Pitch, Sweep, Time, Shape, Grit, Decay, EQ, Clipper, Hold, Volume and Character) for each drum type. Each drum channel has its own trigger and v/oct in addition to extensive CV input options per channel.

Trinity's uniquely performable and switchable output matrix allows for the routing of each drum channel's output to the mix output, the individual drum channel output or both. This makes for easy performability, mutable output, parallel processing, or side chain source.

Lastly, Trinity's midi over USB connection allows for midi control over various parameters via one usb cable. USB midi makes integration a cinch by connecting one usb wire from Trinity to a groove-box or computer - instant integration

All in all, Trinity packs a hefty punch and weighs in at 20hp, 11 knobs, 3 drum channels, 3 triggers buttons, 4 drum synth algorithms based on 4 different types of synthesis, 24 CV inputs, 3 way output switching with 3 individual outputs, a mix output and a midi over usb connection.

Drum Synth Algorithms
BLOCK (Analog Inspired): Drum synth building blocks featuring sine and triangle core. Great for traditional electronic drum creation.
HEAP (Additive): Additive drum synth with 8 partials. Great for fun natural sounds and pitched percussive sounds (i.e. bells, chimes, steel drums, and wood blocks etc.).
NEON (FM): FM drum synth engine. Great for high quality FM drums, clangorous metallic percussion and more.
ARCADE (Noise): Quirky noise generator synth, reminiscent of classic 1980's arcade games sounds - zaps, crashes, explosions etc. Great for claps, hats, even some vinyl noise approximations, and all sorts of fun percussive and degraded noises.

Modes
Cycle Modes
The cycle modes can be enabled and disabled per channel.
'Round Robin' mode will switch between each drum synth type sequentially with each new trigger to the drum channel.
'Random' mode will generate a new random drum sound with each new trigger to the drum channel.
Stack Modes
The stack modes group the channels together allowing 2 or 3 drum channels to be triggered by the primary channel's trigger and v/oct inputs.
Stacked drums can be spread out similar to unison mode on a traditional synthesizer. Stack modes are inspired by the characteristics of chopped breaks where drums tend to overlap and fan out depending on the content of the chopped source material.

Notes: An interface for the case 1/4" jacks in Intelljel cases. The jacks are marked as if they are part of the case, so the jacks marked out, require an input.

The module sports both input and output for either a consumer line level (0.447Vpk) or a professional line level (1.095Vpk). These levels are controllable via jumper on the back of the module. It can also have a single input and output channel switched to pedal level. The case output is fed to the headphone amp that has a corresponding level control. The module otherwise does not have any level control and relies on using a VCA or other module to perform any level controls.

The module can essentially be run in one of three modes:

1) Stereo line level in and out

2) Stereo line level in and out via the left side and mono pedal in and out on the right side. In this mode the stereo line levels leverage TRS on the 1/4" jacks. You can use the included 3.5mm couplers to get TRS on the 3.5mm side.

3) Mono line level in and out via the left side and mono pedal in and out on the right side.

For Palette 64hp users only have two 1/4" jacks. You can choose if you want to use the case jacks as either inputs, outputs, or one input and one output.

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: A really clever take on looping, falling somewhere closer to granular synthesis depending on how you use it. Layer and repeat multiple sound sources to create textures, chords and unique timbres.

Supplier's Notes:
Endless Processor is a dual-channel infinite sound sustainer machine.

Put your favourite instruments, unique timbres, or field recordings - virtually any sound - and make it last forever.

It is not a looper in the usual sense - Endless Processor resynthesizes your sounds to create a perfect clickless stream while preserving the timbral and tonal character of the original.

Endless Processor always listens to audio input and keeps a most recent history. Experiment with sustaining little bits of a sample or make a massive wall of sound with the ability to select how much memorized audio to process.

Stack your sounds to create harmonies, textures, or drones with 5 layers per channel. Each layer can be re-processed or cleared while keeping other ones in place. Set fade-in and fade-out time to quickly or gradually introduce a new layer or remove the existing one.

Additional controls will help you to adjust or shape a channel volume (think built-in VCA).

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

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

Supplier's Notes:
Deva is an expander for Xaoc Devices' Timiszoara multi-fx module designed for creative exploration of the dirty/nasty side of signal processing. Deva opens up the Timiszoara programs you've come to love with some unexpected twists and turns along the way. The analog side features two external feedback loops (for the left and right channel) with tilt filters adjustable via sliders with two additional switches for choosing positive or negative feedback (for each channel). The third slider controls the DAC clock - from overclocking by a factor of two down to 16-times slower, so you can go from chipmunk to hardcore teeth gnashing of underclocked goodness. A switch allows for turning the clock control off for normal/regular operation. All features have inputs for external CV.

Notes: For anyone who has ever struggled with finding their way around a Eurorack synthesiser on a dark stage or a dimly lit studio, Dim 2 presents an illuminating experience. In just 4 HP, it provides a complete solution to upgrade your modular system with a pair of dimmable console lights.

The high-efficiency PWM dimmers run at high frequency, ensuring flicker-free and noise-free operation. Additionally, extensive line filtering keeps your Eurorack power supply happy and clean.

Not limited to just manual control, both dimmers also feature control voltage (CV) inputs, turning the connected lamps from simple light sources to voltage controlled audio-visual spectacles.

While the use of the included BNC LED lamps is recommended in order to keep power consumption low, halogen lamps may be used as well. Provided your power supply is beefy enough, up to 6 W of power may be drawn from each output. This even makes it possible to drive 12 V LED strips, truly making your patches shine bright.

Notes: Digitally-controlled full-analogue path Granular + Multimode VCF

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 analogue domain and goes through analogue circuits from in to out.

The digital processor does not convert or generate audio signals; it is there to control the analogue 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: The Quadigy is a complex envelope generator focused on live play.

The goal is to allow the user setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a subtle and intricate patch once on stage.

This is achieved by offering two main modes, one where full control is available and a Live mode where only the settings that are sensible using on stage are accessible.

The user interface offers an intuitive access for otherwise complex settings.

Advanced features such as automatic time-stretching, multiphase clocking and full morphing put the Quadigy in a category on its own.

Notes: Mixer & CV/clock-controlled Switcher

Focused versatility seems an oxymoron when describing the features that led to the design of the Mixwitch.

With only a pinch of mixing, inverting and controlled switching, Klavis Electronics brew up a plethora of combinations and uses.

This is voltage processing magic!

The Mixwitch design comes from a frustration with attenuvertors (bipolar attenuators-inverters) whose off (neutral) position is difficult to retrieve, especially in live situations.

Klavis went for a digitally-controlled analogue path where polarity inversion would be at the touch of a button. So, the usefulness of attenuating/inverting can be realized by turning the pot down, swiftly pressing the inversion button and reopening the level. The zero level is where you expect it, with the pot full down.

Once a clean polarity control was established, a mute function was added, offering the benefit of pre-adjusted pot settings ready to be activated at will.

The next step was to bring something extra, useful and creative. There are plenty of analogue switches controlled by a clock; but arbitrarily selecting an input with a voltage is less known. Having both control capabilities combined with Klavis' specific mixer features creates a unique fusion: welcome to the Mixwitch!

Notes: KR is based off of the concept of a guitar tonestack: you get a gnarly drive on the top and a super clean two-band shelving EQ with switchable midpoint after that. There are separate ins and outs, too, so if you want to EQ a thing and distort the other thing at the same time you can!

Kith Ruina's inspiration comes from the world of guitar amps. A drive into an EQ is an extremely common configuration for shaping guitar tone, and we find that it works extremely well for synths as well. A grungy drive into a pristine EQ gives excellent tone control, and with separate ins and outs for the two sections KR can be configured to fit into any patch you throw at it.

Notes: Based on the ADDAC501 Complex Random module, the 511 expands the concept to become an even more powerful random/stochastic voltage generator. Four channels, all capable of being used for envelopes, modulation sources, sequencers and much more.

Supplier's Notes:
This module greatly expands on the principles of the ADDAC501 Complex Random from 2013.

This is a fully fledged 4 channel voltage generator capable of all things random, with quantization, probability, distribution, interpolation, time control, clock, states and a 32 step sequencer.

The module operation relies on its screen for all parameter editing, each button accesses one single page where parameters can be changed allowing a fast and fluid workflow across all settings.

Long presses on all buttons have a secondary function allowing fast Channel selection plus Mute and Hold functions.

The combination of having 2 Encoders with Push buttons allow swift navigation and editing across all pages and their settings.

Notes: Mixup is a versatile, expandable audio mixer for Eurorack format. It has eight inputs (6 on the front panel) and two outputs. Inputs 1 and 2 are single-channel mono inputs, each with its own mute switch and level control; Input 3 is a dual-channel stereo input with a shared mute and level control; and input 4 is an auxiliary unity-gain, non-mutable stereo input.

Using bus connectors on the back panel, you can chain multiple Mixups together in series, giving you the ability to mix together even more inputs, or to create sub-mixes for routing around larger systems.

Because Mixup is designed specifically for audio (and not for CV mixing), it uses AC-coupled circuitry (which reduces the potential for 'pops' when muting and unmuting audio), and it uses audio-grade, logarithmic attenuators for a smooth, even response across the entire volume range.
