Notes: Module A-106-5 is a 12dB multimode filter that is based on the filter circuit of the Oberheim SEM module.

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.

The module generates a distorted audio signal if the level control is set to about 50% (i.e. centre position) or more with A-100 standard signals like VCOs.

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: Yet more bargain Buchla collabs from TipTop Audio with this dual voltage processor. Generate CV outputs algorithmically based on multiple inputs, allowing for some seriously complex modulation.

Supplier's Notes:
Model 257 Dual Control Voltage Processor consistsof two identical sections, each of which permits several applied control voltages to define a single output voltage according to the equation:

(Va * K) + ((Vb * (1-M)) + (Vc * M)) + Voset = V_out

The algebraic manipulations possible with this module include addition, subtraction, scaling, inversion, and multiplication. Also incorporated is the capability of using one control voltage (M) to transfercontrol from one applied voltage (V_b) to another (V_c).

Functions

- Attenuverter
Va is the voltage input a for attenuverter (left jack on the panel)
K knob can scale the incoming Va voltage either positively or negatively

- Crossfader
Vb is the voltage input b for the left side of the crossfader (second jack from the left)
+.5 switch adds 5 volts to the input of Vb
Vc is the voltage input c for the right side of the crossfader (fourth jack from the left)
M scales Vb from 1 to 0 based on the position of M knob
M scales Vc from 0 to 1 based on the position of M knob
The middle CV input at M/M can crossfade between Vb and Vc (third jack from the left)
The M knob and M CV added together to control crossfade position

- Oset
Voset Adds 0 - 10 volts to any combination of Va + Vb + Vc

- Output
Vout is the combined voltage of the attenuverter, crossfader and oset (right jack on the panel)

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: A-138s is a simple but useful 4-in-2 mixing tool. It has four inputs available. Each input is equipped with an attenuator (Level) and a panning control that is used to distribute the signal to the left and right output. Beyond stereo mixing it is equally suited to create variable parallel routings. For example: Any of the four inputs may be routed in variable intensity to feed two filters.

You may regard the A-138s as a smaller version of the A-138m Matrix Mixer.

Inputs and outputs are DC coupled, i.e. the module can be used for the mixing of control signals too.

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.

Notes: Rings is a resonator, the essential ingredient at the heart of several physical modeling synthesis techniques. The resonator transforms an external, unpitched excitation audio signal into a full-bodied pitched sound. Rings is the bar, the tube or the bunch of strings you cause to vibrate with a bursty external signal.

Any signal can be fed into the resonator, including envelope clicks, trigger signals, noise bursts, even tonal sounds. It also contains a special "polyphonic mode", where four notes can ring together at the same time. Although it is not truly polyphonic, it adds density and chordal characters to the sounds output. For those wanting the functions of Elements without the losing HP real-estate, Rings is exactly the solution.

Three families of vibrating structures are simulated by the module, with CV control over their parameters:

Strings, membranes and tubes as modelled by Elements' resonator section (modal synthesis).

Strings coupled together and vibrating in sympathy, with controllable intervals between them.

Strings with a variable amount of inharmonicity.

Rings can be configured so that each new note is played on its own virtual string, while the previously played note(s) still decay. This unique take on polyphony allows the module to play strummed chords.

Controls

Number of strings/structures (1, 2 or 4).
Synthesis model (modal, sympathetic strings, string).
Main frequency (quantized in semitones).
Structure. With the modal and string models, controls the inharmonicity of the spectrum (which directly impacts the perceived "material"). With the sympathetic strings model, controls the intervals between strings.
Brightness. Specifies the brightness and richness of the spectrum.
Damping. Controls the damping rate of the sound, from 100ms to 10s.
Position. Specifies at which point the structure is excited.

Inputs and Outputs

Frequency, structure, brightness, damping and position modulation CV inputs with attenuverter (-8V to +8V).

"Strum" trigger input to indicate when a new polyphony voice needs to be allocated. Normalized to an edge detector detecting changes on the main V/Oct input, or sharp transients on the audio input. Detection threshold at 0.6V.

1 V/Oct frequency input (-1V to +5V).

Resonator audio input, normalized to a filtered pulse/noise burst triggered by the "Strum" input (for stand-alone use). Modular level, up to 16Vpp.

Two audio outputs, splitting the signal into even/odd partials in monophonic operation, or even/odd notes in polyphonic operation.

Notes: Tap into the fascinating world of random modulation and creative signal processing with our innovative 2HP Eurorack compatible Dual Sample and Hold module. This compact but powerful tool is a must-have for anyone who wants to enrich their soundscapes with unique, unpredictable textures and sequences. Perfect for experimental musicians, modular synth enthusiasts, and creative sound designers.

Space-saving design

With its narrow 2HP width, the Dual Sample and Hold module fits seamlessly into any Eurorack system without compromising on functionality.

Dual operation

Two independent sample and hold channels give you double the creativity. Use them for stereo effects, parallel modulation sources, or complementary CV sequences to add a new dimension to your sounds.

Standardized inputs

A special feature of this module is the normalization of the "in" and "trigger" inputs of the second channel to the first. This means that the second channel will automatically pick up the signals from the first channel if no separate inputs are connected. This intelligent linkage allows you to create complex, interconnected modulations with just one input signal.

Flexibility of use

Whether you want to create random melodies, rhythmic variations, or dynamic soundscapes, this module gives you the flexibility you need. Experiment with different input signals and triggers to achieve surprising and inspiring results.

Intuitive operation

Despite its sophisticated functionality, the Dual Sample and Hold module is intuitive to use. It is therefore suitable for beginners in the world of modular synthesizers as well as for experienced users who want to expand their sound palette.

Notes: The Multiple is a simple but important module that allows for sending a signal to multiple destinations. Within the Make Noise system the Multiple may also be used for combining clock, gate and pulse signals together to create interesting timing sources (in other words, it acts as a Gate combiner aka logic OR circuit).

It has 9 inter-connected sockets that may be split into different group combinations depending upon how it is patched. The jacks circled in white will make or break the interconnects between the 3 groups of three, thus allowing for three 3-way, one 5-way/ one 3-way or one 7-way multiple.

The Multiple is passive, because the Make Noise system does not require Buffered Multiples since all critical control signals are already buffered in such a way as to provide a large fan-out capability.

Notes: Tune is a multi-scale pitch quantizer. It features 11 scales ranging from chromatic to octatonic with everything in between. In addition, the bias control allows the user to transpose the melody to a different octave or starting note.

This functionality opens up every musical mode for each of its 11 scales and provides a performable control for transforming melodies on the fly.

Notes: MEGA-TANG Expander MT-EX2 is a new expander module for the MEGA-TANG mixer.

The MT-EX2 adds an extra effects send/return for all channels. It also adds an extra send and return to your MEGA-TANG. Note the MEGA-TANG only supports a single expander at any time.

Notes: Module A-185-2 is a precision control voltage adder/buffer. Precision means that the amplification of the inputs without attenuators is exactly 1.00 and is suitable to add control voltages for the pitch control of VCOs (e.g. from keyboard + sequencer 1 + sequencer 2). Summing resistors matched to 0.1% are used to obtain an accuracy of 0.1% for the added voltages.

The module is equipped with four CV inputs: one with attenuator and three without attenuator. Each input is normalled to +1 V (i.e. if no plug is inserted the input contributes 1 V to the sum appearing at the output).

The input with attenuator can be used for common modulations (e.g. from an LFO, ADSR, Theremin, Pitch-Bender) for all VCOs connected to the output. The Lev.1 control is used to adjust the depth of the modulation, the first switch selects the polarity of the modulation. If no signal is connected to the first socket the attenuator works as a (fine) tuning knob because a voltage in the range 0...+1V (right position of the switch) or 0...-1V (left position of the switch) is added to the CV output.

The inputs without attenuators are planned to add control voltages coming out of keyboards, sequencers, Midi-to-CV interfaces, ribbon controllers or other CV sources that follow the 1V/oct standard. For example the CV of a keyboard can be used to transpose the CV coming from a sequencer, or the CV of a slow sequencer can be used to transpose the CV from a fast sequencer.

Each input is equipped with a three-position switch that determines if the corresponding voltage is added (right position), subtracted (left position) or if the input has no effect (centre position). If no plug is inserted the corresponding switch works as an octave switch for the lower three sections as the default 1 V are added or subtracted to the output voltage according to the switch position. The first switch can be used to add a variable voltage to the sum output. The variable voltage is adjusted with the Lev.1 control and the knob works then as kind of a (fine) tuning control.

The module is equipped with 4 outputs: three non-inverting and one inverting ouput. An internal jumper can be used to connect the non-inverted or inverted output to the CV line of the A-100 bus. That way the module can used to control several VCOs that are connected to the same bus board as the A-185-2 (same functionality as A-185-1).

Notes: Glitchy business with this digital module based on the sound of scratched CDs, buggy software and failing hardware. Stereo in and out with up to five minutes sampling time.

Supplier's Notes:
Data Bender is a circuit bent digital audio buffer. It is inspired by the ways in which audio equipment can fail. The sounds of skipping CDs, software bugs, and defective tape machine playback are all accessible. The audio buffer can hold up to five minutes of stereo audio, providing a sonic canvas capable of infinite surprises and discovery.

Notes: Hat is a hi-hat cymbal with a wild side. Finding something unique is easy with a blend of sounds ranging from robotic to metallic. At its core are three unique sound sources made up of six oscillators, a noise generator, and a number of filters. Sizzle affects each source independently, adjusting oscillator and filter frequencies, allowing for a broad range of sounds. In addition, separate trigger inputs for open and closed allow for a complete hi-hat pattern on a single module. No matter what situation it's in, Hat provides shimmering, metallic timbres for any percussive purpose.

Notes: The mmMidi is a simple & compact MIDI interface for your Eurorack synthesiser. It translates two independent channels of MIDI note, velocity and gate information to corresponding control voltage signals via either a classic MIDI DIN type connection or as a driverless USB MIDI device.

The mmMidi also converts MIDI Clock to analogue x24 fixed clock and run outputs (i.e DIN Sync). The optional mmT expander provides a third MIDI channel of 8 key mapped gate outputs.

Requiring minimal configuration and a pain free set up, the mmMidi makes it easy to sync Pam's clock to your DAW, control multiple synth voices, and trigger drum or sample modules with the optional mmT expander. The new USB-C connection makes it easy to drive your modular not just from your computer but also via your tablet, phone or any USB MIDI Host.

Notes: 'Akemie's Castle' is a dual voltage controlled oscillator with authentic 4 Operator digital FM using 'new-old-stock' Yamaha IC's for audio signal generation.

Each of the 4 operators feature independent waveform selection, frequency multiplier and level control via direct panel operation and voltage control. Operators can be combined in various ways across both oscillators, which together with independent feedback control on each VCO, offer an extremely wide palette of sounds.

Oscillator A also features a chord mode providing a range of up to 5 voice chords and voltage controlled inversion.

Notes: Mutes goes above and beyond basic muting by allowing you to split groups of signals to multiple destinations, making it great for FX dub performing and varied signal routing.

You also get a three position switch giving you: MOMENTARY signal pass through (it springs back to the centre when released); OFF (or muted) in the centre; and ON to the right. We've also added vactrols to the circuit giving the switching a pleasing decay for both audio and modulation as well a totally click free muting. This module can add mutes to anything, your mixer, module inputs or outputs, modulation signals, sequencers, gate sources and more.

Mutes was developed by Befaco on behalf of DivKid.

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: The WT-QUAD-LFO module consists of four individual, digital, wavetable based low frequency oscillators (LFO) with an easy and intuitive featuring a 1.8" OLED color display. The module can be updated easily by inserting a flash drive with the firmware files in the USB port on the front panel.

The oscillators and their respective controls, inputs and outputs are organized in four channels. The frequency of each oscillator can be linearly or exponentially (1V/Oct.) controlled through the voltage applied to the corresponding CV input.

Each LFO channel can output one of the predefined waveforms (including sawtooth, ramp, square, sine, triangle), morph between two different waveforms or generate a random waveform. It can be externally reset through the sync input.

Each trigger output can be set to output a specific phase of the corresponding waveform.

The module offers cross frequency modulation (FM) and internal sync between LFO channels. It features also phase distortion and phase spreading of the outputs, including a classical quadrature mode (90- phase spread). Frequency relationships between the four LFOs can also be set.

Notes: 3xVCA ofers three high class amplifier circuits with linear characteristic. Thanks to AC / DC compatibility, a very low noise floor and basically no distortion, the module is not only a great partner for control voltages, but audio material as well. Besides a signal input and output, each VCA has its own CV input. The dual potentiometers regulate levels and bipolar CV attenuation values of all amplifiers. Using these rather unusual, yet very practical components, it was possible to equip the 3x VCA with a front panel that is only 6 HP wide. Switches allow the user to feed the results of one amplifier to the output of the next amplifier, so we can get 1+2, 2+3, and 1+2+3 outputs mix. Two-colored LEDs visualize CV and output signals.

Notes: Tiny little low-pass gate in Intellijel's compact 1U format. Great value approach to this west coast classic module, based on a vactrol for that natural, organic sound.

Supplier's Notes:

Drop this module (or a few of them) into your 1U row, patch in some sound sources, and then ping them with gates and CV to get some instantly pleasing results. So simple and fun!

Natural dynamics with the magic of vactrols.

In general, low pass gates (LPGs) control the amplitude and timbre of a signal by opening and closing a low pass filter. When the gate is closed, no frequencies are allowed to pass through (and no output is heard). As the gate begins to open, the lowest frequencies pass through to the output. As the gate opens further, the output grows louder and its high frequency content increases.

Traditional Low Pass Gates use vactrols to control the opening and closing of the filter. Encased within a vactrol is both a light source and a light detector. Applying a control voltage to the vactrol lights its internal LED i the brightness of which is measured by its detector. What makes vactrols particularly unique (and well-suited to musical applications) is their non-linear response to voltage - in particular, the way in which the internal LED slowly dims (rather than shutting off instantly) when the control voltage is removed. This sonic coupling of timbre and volume, along with the circuit's natural decay, makes the low pass gate particularly adept at producing tones associated with struck objects, like hand drums or marimbas. Indeed, low pass gates are the main ingredient of the so-called Buchla Bongo sound.

The Intellijel Passive Low Pass Gate 1U is a simple, vactrol based, 1-pole, passive low pass gate, which is controlled by an external CV input. Without positive control voltage, the gate is completely closed and none of the LPG's input signal is passed through to the output. Increasing amounts of positive CV open the gate i making the output signal both louder and brighter. At +5V, the gate is fully open and the input signal is passed through to the output.
This makes LPGs sound very different (and more acoustic) than the traditional complement of envelopes, VCFs and VCAs that are employed in most subtractive synthesizers. Exciting the vactrol (via the CV input) with a trigger, noise blast, or short envelope will result in a very natural sounding filtered envelope that's reminiscent of the sonic characterics of struck objects, which are allowed to decay naturally.

In addition, because this is a passive circuit (no power is applied to it), its sonic characteristics are somewhat dependent upon the audio signal you feed into it, making it a very natural and organic way to shape a signal's volume and tone.

Pairs very well with the intellijel Shifty module to derive polyphony out of a only a few HP of modules.

Notes: Module A-130-8 contains eight linear voltage controlled amplifiers (VCAs). Each VCA features a control voltage input (CV), a signal input (In) and a signal output (Out). In addition three mixers are included: the socket labelled "1-4" outputs the sum of the VCAs 1-4, the socket labelled "5-8" outputs the sum of the VCAs 5-8, the socket labelled "1-8" outputs the sum of all eight VCAs.

The signal inputs are able to process levels up to about 20Vpp without clipping (20Vpp = 20V peak-to-peak or about -10V...+10V) . Each CV input is equipped with a trimming potentiometer that is used to adjust the sensitivity of the CV input in question. In the factory the module is adjusted for the CV range 0...+5V but can be re-adjusted by the user for other control voltage ranges (e.g. 0...+10V).

The amplification range for each single VCA is 0...1. The signals of the sum outputs have a lower amplification to avoid distortion at the sum outputs.

The VCAs and mixers are fully DC coupled, i.e. the module can be used for the processing of both audio and control voltage signals. The control voltage and signal inputs can be normalled by means of small solder pads (e.g. 1 > 2 > 3 > 4 and so on, or 1 > 5, 2 > 6, 3 > 7, 4 > 8 for the stereo application mentioned below).

Typical applications

any kind of VCA application (e.g. voltage controlled attenuation of audio or control voltage signals)
two voltage controlled mixers with four channels each
voltage controlled stereo mixer with four channels each, for this the control voltage inputs have to be correspondingly patched or internally normalled: CV1=CV5 /CV 2=CV6 / CV3=CV7 / CV4=CV8
voltage controlled mixer with eight channels
add-on for the Joystick module A-174-4
Technical notes

The following document shows the positions and functions of the jumpers and trimming potentiometers of the module: A130_8_trimming_potentiometers_and_jumpers.pdf
When the trimming potentiometer in question is moved CCW (counterclockwise) the sensitivity of the CV input in question increases (view to the top edge of the module).
Trimming procedure: apply the max. CV voltage that will occur in your application (e.g. +8V) to the CV input and a constant audio signal to the audio input (e.g. a VCO sawtooth). Then adjust the trimming potentiometer in question until the max. output level is reached and does not become higher even if the trimming potentiometer is turned further. Possible the the trimming potentiometer has to be turned back again a bit to find the correct position.
With the trimming potentiometer adjusted to max. sensitivity the linear amplification starts at about +0.1 control voltage (CV). We introduced this small dead range of about 100 mV to make sure that the VCA fully closes with CV = 0V.
It's possible to change the amplifications of the internal mixers used for the sum outputs (1-4, 1-8, 5-8) also to 1. Pay attention that then clipping/distortion may occur at the sum outputs. For this the 22k resistors R41 (Sum 1-4), R44 (Sum 5-8) und R51 (Sum 1-8) have to be replaced by 47k. As they are smd resistors sufficient experience with soldering/desoldering of smd parts is essential. And we have to point out that warranty is void if such modifications are carried out by the customer. The positions of the resistors are shown in the document A130_8_trimming_potentiometers_and_jumpers.pdf.
If multiple exponential VCAs are required module A-132-4 is recommended.

Notes: The Voltage Controlled Amplifier or "VCA" is one of the most essential and useful building blocks in a synthesis patch. The DUAL VCA 1U packs two high quality, DC coupled, linear VCAs into a very compact 1U package.

The two VCAs can be used completely independently or in tandem via the handy signal normalling. The DC coupling means that the VCA can be used for the amplitude control of both control voltages (CV) and audio signals.

Some application/use examples:

- Dual, independent VCA for dynamic level control of two different audio or cv sources
- Stereo VCA (use the CV normalling where CV A normals to CV B) for processing stereo sources or CV pairs.
- CV/Audio summing (when Out A is not patched, it normals to sum with OUT B, CV A and B control the independent levels)
- Voltage/signal doubling (use input A only and the doubled voltage will appear at OUT B when a CV of +5V applied to CV A)

Notes: Module A-182-1 is a simple passive multi-connector similar to the multiples modules A-180-1/A-180-2. In contrast to modules A-180-1/2 each socket is equipped with a 3-position switch that allows to connect the corresponding socket to the internal bus #1 (left position), bus #2 (right position) or to turn the socket off (centre position).

Examples:

- All switches in left position or all switches in right position: 8-fold multiple

- Four switches in left position and four switches in right position: two 4-fold multiple

- X switches in left position, Y switches in right position and Z switches in centre position: two separate multiples with some sockets turned off

Notes: VCO:

- Tune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
- Oct: range switch -1 / 0 / +1 octave
- Mod: modulation depth (attenuator wired to the Mod. socket)
- Dest: switch that is used to address the modulation to frequency modulation (position FM) or pulsewidth modulation (positon PM), in centre positon no modulation
- PW: manual pulsewidth control for rectangle waveform, PW can be also modulated by the Mod. input as mentioned above
- Wave: waveform switch (sawtooth / off / triangle), the sum of the waveform chosen by this switch and the rectangle is fed into the VCF (to turn the rectangle off the PW control has to be set fully CCW or fully CW)
- 1V/Oct. (socket): external CV input for VCO frequency (1V/octave)
- Access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)
- Triangle core VCO, frequency range about 32Hz ... 8kHz

Balance unit:

- The balance unit is made of two VCAs which are controlled by the sum of manual Balance control and the balance CV input in the opposite direction.
- The audio input of VCA1 is hard-wired to the VCO output, audio input 2 is connected to the socket Ext.In.
- The output of the balance unit is used as audio input for the VCF
- Bal.: manual balance control, fully CCW the internal VCO is used, fully CW the external signal (Ext.In) is used, at centre position both signals have about the same level
- CV Bal.: CV input for balance (range about 0...+5V)
- Ext. In: external audio input for VCA2, about 5 Vpp level required for similar loudness as the internal VCO
- This socket is normalled to the internal VCO suboctave f/2 signal (rectangle with half the frequency), if no external signal is applied the suboctave signal is used as the second signal for the balance unit

VCF:

- 24 dB low pass
- Frq: manual frequency control
- FM1: frequency modulation depth (attenuator wired to the VCF FM1 socket, the socket is normalled to the internal Envelope signal and then FM1 controls the modulation depth of the internal envelope applied to the filter)
- FM2 (socket) : second CV input for VCF without attenuator (about 1V/octave), can be used e.g. for VCF tracking by connecting the same CV which is used also for the VCO frequency
- Res: manual resonance control (up to self oscillation)
- If the VCO is turned off (waveform switch = centre position, pulsewidth control = fully CCW or CW) and the VCF resonance is set to maximum the module can be used as a sine oscillator, the tracking at socket VCF FM2 is about 1V/octave (not as precise as the VCO but much better than most other filters)
- ~ 11 octaves frequency range (~ 10 Hz ... 20kHz)

VCA:

- Gain: manual amplitude control (initial gain), can be used to open the VCA without envelope signal
- VCA (switch): used to switch between gate and envelope as control signal for the VCA, in centre position the VCA is not controlled by envelope or gate
- Note: when gate is used the VCA is controlled directly by the gate signal (i.e. hard on/off), this may lead to clicking noise under certain conditions (especially with low VCO/VCF frequencies)
- Special control scale: exponential scale in the range from about -20dB to -80/90dB, linear scale from about -20dB to 0dB
- Remark: this special control scale results in a loudness behaviour that is a bit different from pure linear or exponential VCAs
- Out: audio output of the module (= VCA output)

Envelope:

- Gate (socket): Gate input (min. +5V), can be normalled to the bus gate signal by means of a jumper
- Att: manual control for Attack
- D/R: manual control for Decay/Release
- Env. (switch): used to switch between A/D, ADSR and A/R mode of the envelope generator, in centre position (ADSR) the sustain level is fixed to about 50%
- Envelope (socket): envelope output (about +10V)
- CVT (socket): CV input for time control, by means of two internal jumpers one can select which time parameters are controlled by the CVT input (e.g. A only or D/R only or A/D/R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question)
- Envelope LED display
- Attack time range: ~ 1ms ... 5 sec (can be extended by using the CVT input)
- Decay/Release time range: ~ 1ms ... 15 sec (can be extended by using the CVT input)

Notes: The A-138d primarily is used for crossfading between two modular signals. On the other hand you can used it for inserting stompboxes or other effects into your modular system. Both the inputs and the mix output are available twice, like a mini-multiples e.g. for using the input signal also for other applications, kind of like a Thru.

Crossfader: With the crossfading control CF you blend manually between the inputs In 1 and In 2. The Mute switch allows for muting one of the two signals, independent on the crossfader position.

Effect insert: The signal at input In1 is emitted at the FX Send output and can be attenuated with the Atten. control because the modular system works with much higher levels.

The effect unit's output is inserted to the FX Return input socket and its level can be boosted with the Amp. control. The processed signal is available at the bottom in 2 socket.

Use the CF control to blend between the original signal and the effect signal and to mute switch for quick muting e.g. of the effect return signal.

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: The Meng Qi DPLPG is a Dual Passive 1-pole vactrol based Low Pass Gate/VCA in modest 2 HP. No power is required as the design is completely passive.

Handpicked components ensure that the modules will be musical.

Feed it a trigger and enjoy the natural smooth decay of a vactrol.

Notes: Module A-140-2 contains two ADSR type envelope generators 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. 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. Changing the positions of the mentioned jumpers allows to modify the factory settings.

Notes: Module A-151 (Quad Sequential Switch) is like an electronic four-position rotary switch.

It includes trigger and reset inputs, four in/outputs, and a common out/input. Each time a pulse is received at the trigger input socket, the common out/input is connected to the next in/output. After the fourth in/output, the next trigger makes it step back to the first again, and so on. A positive pulse at the reset input switches the out/input immediately back to the first in/output. Voltages in the range -8V...+8V at the O/I resp. I/O sockets can be processed by the module.

Four LED's indicate the active in/output (ie. the one that is connected to the out/input at any particular time).

Notes: ADSR is a four stage linear envelope with two expressive ranges. Each stage can be modified independently allowing for the creation of complex, multi-segment envelopes. Great for modulating filters, VCAs, and oscillators.

Notes: The WAV Recorder from 4ms Company is a high fidelity, two-channel stereo audio recorder with basic playback features. Accepting a wide range of input signals, from line-level to modular-level, the WAV Recorder stores audio onto a microSD card in lossless .wav format up to 96kHz/24-bit. The trigger jack can be used for capturing rhythmic loops or synchronizing multiple WAV Recorder modules for multi-track recording. In Playback mode, the trigger jack or button plays the most recent recording. A simple file/folder navigation system can be used to browse the folders on the card for playing back .wav files. A Gain knob allows for up to +20dB of boost, and an LED Signal Meter indicates clipping and the signal level.

Notes: LYRA8-FX is a processor that can give you a significant part of the mysterious LYRA-8 sound thanks to the FX section from the LYRA-8, expanded with CV controls and packed into a Eurorack module.

It contains a double modulated lo-fi delay with cross-feedback and the unique possibility of self-modulation, where the delay output signal modulates its own sample rate. Also, it packs a parallel distortion with CV control of the drive. The distortion is after the delay. It's much more than a delay - you can get a simple reverb, comb filter, chorus and much more cool FXs which are hard to describe.

It has a famous LYRA-8 build quality - no SMD, no twisted plastic shafts.

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: From trickling hi-hats to thunderous kicks. The Befaco Percall 4-Channel VCA/Delay Envelope Module is designed to take care of all percussive aspects of your Eurorack rig. You'll be able to create a whole host of percussion thanks to the 4 VCAs, volume control and decay options. By using the trigger you'll be free to open the VCA whilst the volume knob helps determine the level of the percussive sound you've sculpted. Take your tones to the next level thanks to the inclusion of an output on the envelope. You can apply this to the pitch of the oscillator to achieve a fat kick drum which offers excellent low frequency energy. The Percall 4-channel module is the ultimate addition to your Eurorack.

Notes: Universal drum synthesizer with roots in the analogue world on a swappable oscillator platform

Basimilus Iteritas Alia is a parameterized digital drum voice with its roots in the analogue world. At its heart, the BIA is a simple six-oscillator additive and FM synthesizer with waveform, harmonic spread, and envelope controls. An adjustable noise oscillator and an extreme take on a wavefolder round out its synthesis abilities. Its straightforward controls make sound design fun and performable: create sub-shaking kicks, snares, hats, and unique drum hits with just a few tweaks.

BIA is a classic percussion module but you'll be blown away by how much more it can do. Use it for leads, basslines, or build a whole drum kit with some external CV. Plus, the envelope output means you can use the BIA for shaping and modulating other parts of your patch.

Basimilus Iteritas Alia 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.

Notes: Two channel expander for Bartender

Mixer section

Each channel has the following:

Stereo or mono - Each channel can be treated as a stereo channel or a mono channel with two summed inputs.

CV inputs for both panning and level control

Two send buses - You can route each channel to one of two send buses. Each send bus is stereo. You can choose if you want the send to come before or after the level/panning controls.

Mute - The mute has both latching mute (up) and a momentary mute (down). The mute uses a capacitor to slow the turn off and on of the mute action. So it is mostly click-less, but you may find an occasional pop.

Cue bus - You can route each channel to the cue bus.

Expandable Mixer Series

Bartenders can be cascaded to create 8ch, 12ch, or 16ch mixer. The main level is what is sent the main level control can act as a group control.

Barbacks can be added to add 2ch to your mix. Barbacks can also be cascaded enabling up to a 16ch mixer configuration.

Send-VCA can be added for CV control of the level of the send.

DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.
