Synth modules

Notes: Module A-124 is a special 12dB multimode filter using the "strange" filter circuit of the "EDP Wasp" (an analog synthesizer with black/yellow case built end of the seventies, manufactured by the UK company "Electronic Dream Plant" with Chris Huggett und Adrian Wagner). This design "abuses" digital inverters as analog operational amplifiers leading to distortions and other "dirty" effects that generate the specific sound of this filter. The filter is equipped with a band pass output and a combined low/notch/high pass output. For this output a control knob defines the relation between low and high pass signal. If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates. The module does not feature self-oscillation in contrast to most of the other filters of the A-100 system.

Inputs: Audio In, CV In (2x)
Outputs: Bandpass Out, Low/Highpass Mix-Out
Controls: Audio and CV attenuator, Frequency, Resonance, LP/HP Mix

The function and operation of this module is very similar to the module SEM VCF A-106-5. But the sound of both filters is very different! The only functional difference is the position of the sockets and controls, and the function of the controls CV2 (A-124: normal attenuator, A-106-5: polarizer).

Notes: The Morphagene is a next generation tape and microsound music module that uses Reels, Splices and Genes to create new sounds from those that already exist. Search between the notes to find the unfound sounds.

A few of the Morphagene's most basic uses: Splice recorded audio and jumble it using ORGANIZE. Manipulate playback speed and direction with Vari-Speed. Granularize with Gene-Size and Slide. Layer or Stagger Genes using MORPH. Undertake iterative music processes by recording manipulations and overdubs into new Splices, like having two machines (one for Playback and modulations, one for Record). Process sound in real time using Time Lag Accumulation. Utilize envelope following CV OUT and EOSG Trigger to engage Morphagene in conversation with the rest of your modular system. Stretch and squash sound with Clock input.

***MG137 Firmware Update:

Change Log

1. Improves Vari-Speed response for slow modulation rates.

2. Improves SD Card file format for more compatibility with software .wav file formats.

3. Doubles total record time per Reel.

Upgraded memory performance offers an increase from 1.45 minutes to 2.9 minutes of record time.

If you are using Splices that are over 1 minute long the SLIDE parameter will be scanning across a massive amount of material and therefore the longer the Splice the longer it will take to get to where you are Sliding toward. Imagine a tape machine shuttling forward or backward to get to your desired destination. No we cannot change this, the MG is scanning as fast as possible. This new double record time firmware will make this even more of a factor.

The new options mcr1, mcr2, and mcr3 allow user-definable Morph Chord Ratios (detuning of 2nd through 4th Genes with Morph at its highest settings).

The Auto-level procedure has been replaced with an improved input gain staging, accessed with a 4-step gain selection.

Playback gain is reverted to pre-mg157 level to improve TLA and Record-Into-New-Splice functions.

Internal processing improved to work with (2) and (3) to significantly improve signal-to-noise ratio on input and playback.

And more!

Notes: The Quad VCA is a compact and feature packed module that is sure to find its way it almost all of your patches. In addition to being used for standard VCA duties it can also be used as a mixer and signal booster.

Features:

- Manual LEVEL control per VCA which is convenient when using the module as a mixer or for biasing when CV modulating the VCA with a bipolar LFO.
- Dedicated CV attenuators with dual colour LEDs for monitoring bipolar CV signals.
- Continuously adjustable response from linear to exponential per VCA.
- Each CV input is normalled to the adjacent one for cascaded control.
- Each output is normalled to the mix input of the adjacent one which allows you to use adjacent sets as submixes or the fourth output can be used as a master mix output when none of the other outputs are patched.
- Each VCA has a boost switch that increases the output level by approximately +6dB (double).

Notes: Zadar is a powerful, four-channel envelope, modulation, and transient generator, in a compact yet very complete, feature-rich package. It is capable of synthesising a vast palette of envelope shapes starting from hundreds of shapes stored in the memory. These starting shapes are not mere wavetables, but flexible vectors that can be stretched (from a fraction of a millisecond to half an hour), flipped, warped, distorted, delayed, shuffled, repeated, and amplitude modulated in real time. A set of freely assignable CV inputs allows for external control of most parameters. Each channel can work independently or combined with other channels within one of the chaining and looping algorithms.

Operating Zadar is quick and immediate, thanks to its accessible interface and crisp OLED display. The main screen displays all parameters together with the currently selected shape. Entering the simple 3-page menu is needed only for advanced settings.

Notes: The shorter and wider brother to the popular Triatt module!

The four handy knobs can act as active attenuators (unipolar) or attenuverters (bipolar) depending on the setting of the two-position switches above each one.

Each input is normalled to a precision +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 v or -5 to +5 v depending on the position of the mode switch.

- 2 modes for each channel
- 5v normalled to each input
- With external signals it acts as active/buffered attenuator/attenuverter/mixer
- Each output normalled to mix into the adjacent channel on the right making it possible to do sub mixes in groups of 2, 3 or all four channels.

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: The 'HPO' is an affordable super slim and skiff friendly no frills stereo headphone driver output for your modular synthesiser. Includes a volume control and ability to double up a mono signal into stereo. A great use for that left over 2hp in a skiff or larger system.

Give loved ones, friends and acquaintances a break from your musical 'genius', the HPO offers a solitary cell for focused creativity impregnable from undeserving non-believers.

Notes: Eight channels of audio and CV sampling with real-time editing and processing. Does basic sampling well but quickly gets creative and weird.

Supplier's notes:
The 'Squid Salmpler' is a Eurorack 8 channel audio & CV sampler. It is designed for immediate real time sampling, editing and mangling within a modular context.

Taking influence from early hardware samplers, The Squid Salmple focuses on usability and instinctive operation, incorporating a proven Pamela's Workout style user interface for minimal screen dependence and a fun, hands on experience.

With support for sampling and playback for both audio and CV, as well as CV control of all parameters, on-the-fly bank loading and saving to USB, The Squid Salmple brings a unique take on old school sampling into the modular realm.

The Squid Salmple comes with a USB Stick containing approximately 90 banks of original carefully curated royalty free samples. This includes a wide range of sounds from classic drum machines and weird synths to field recordings and CV modulations. Banks are provided by both ALM and some of our favourite artists and friends including Mumdance, Solid Blake, Russell Haswell, Lauren Flax, Dave Burraston (NYZ), Sue Zuki, Dungeon Acid, Sasha Lewis and Andrew Duff.

Notes: Best value Buchla module ever? An official Buchla module produced by TipTop Audio, the 258t is a dual triangle-core oscillator, with sine/sawtooth wave shapes in the top half and sine/square at the bottom. Bags of character.

Supplier's Notes:
Two independent voltage-controlled oscillators. Each has one processing input, a frequency modulation input and a 1V/oct input.

Waveshapes, as well as frequency, can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

Trimmers:

There are three trimmers for each oscillator on the back of the module:

1V/oct is the octave tracking trimmer and is set at the factory using high precision instruments.
SHAPE is the trimmer that set the sine wave, for the lower harmonic content of the sine wave.
VC WAVE SHAPE sets the response of the waveshaper to the incoming control voltage. Both SHAPE and VC WAVE SHAPE trimmers are used to adjust the sine wave purity.

Power: +12V 70mA / -12V 40mA

Notes: 'Tangle Quartet' is a high quality quad linear voltage controlled amplifier (VCA) providing individual level control of 4 signal inputs with both individual outputs and a combined 'mix' output (for non patched outputs) . Control signal inputs and associated attenuation controls allow for voltage control of signal levels. Control inputs are normalised to 5v thus providing manual mix control in the absence of control signals.

Technical Specifications:

Supply: +/-12V (Reverse voltage protection)
Current Draw: ~80ma
Size: 8 HP
Depth: 32mm (including power header)

Notes: 'O/A/x2' is a dual channel attenuverter with each channel also including a bipolar voltage offset and LED monitoring. The module is primarily intended for fine grain flexible 'editing' of control signals (i.e changing the phase, level and DC offset of an LFO signal) but also has uses with audio signals such as attenuation, inversion and mixing.

Technical Specifications:

Supply: +/-12V (Reverse voltage protection)
Current Draw: ~50ma
Size: 4 HP
Depth: 32mm (including power header)

Notes: Module A-119 (External Input / Envelope Follower) is designed to allow external audio signals to be integrated into the System A-100. It comprises a pre-amp, envelope follower, and comparator.

The pre-amp has two inputs: an unbalanced input for line level signals, with a gain factor of from 0 to 20, and a balanced input with a gain factor of from 0 to 500, for insertion of low level signals, for instance from a microphone or electric guitar.

The Envelope Follower reads the signal level of the input, and puts out a proportional voltage as an envelope at its own output.

The comparator generates a gate signal whenever the input goes above an adjustable trigger threshold.

Three LED's help you keep track of overload, the envelope, and the gate signal.

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: 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: 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: Belgrad is an all-analogue voltage controlled filter module which - on par with our other modules - brings something new to the table. While it can be used as a traditional VCF for "academic" subtractive synthesis, we guarantee countless hours of exciting timbral explorations thanks to its unique character, flexibility, and features. The most prominent feature is that it offers a multitude of frequency responses with two resonant peaks.

- Eurorack synth compatible
- 14HP, skiff friendly
- Current draw: +45mA / -42mA
- Reverse power protection

Notes: Funky quad filter, based around four identical state-variable VCFs configured in two pairs for either mono or stereo use. At its best when used in stereo, adding movement and width to sounds.

Supplier's notes:
The Quad Peak Animation System combines the auditory enveloping of stereo spaced peaks with the animation of two or more peaks in a single channel dancing around each other or engaging in primitive vocalizations. QPAS is Quad Core, containing four identical state variable filter cores with a control system powerful enough to guide them in stereo multi-peak operation, but simple enough to encourage system integration rather than domination.

- Quad Core Stereo Analogue
- Multi-Peak with clean resonance
- Fast response encourages deep FM
- Radiate spaces stereo image and animates associated channel
- High Q settings are under damped, excitable and ring by gate or trigger
- 2 modulation inputs aid patch exploration
- Stereo VCA, pre-filter with gain
- Mono to Stereo, Stereo to Mono, Mono to Mono and Stereo to Stereo operations
- Smile Pass filter response unique to QPAS
- Low Pass, Band Pass, High Pass and Smile Pass outputs simultaneously available

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: Dual 1 x 4 buffered mult (one audio or cv signal in with multiple buffered outputs).

The output of the first mult is normalled to the input of the second mult to create a 1×8 buffered mult.

Notes: Super-versatile quad envelope generator and LFO source from the Vancouver Eurorack brand. All CV controllable and with tons of shaping options.

Supplier's notes:
The Intellijel Quadrax consists of four independent, CV-controllable channels, each of which can be configured to perform any one of the following functions:

- An AD (Attack, Decay) envelope
- An AHR (Attack, Hold, Release) envelope
- A cycling envelope (resulting in a unipolar LFO)
- A pulse burst generator (Finite repeated functions that ascend or descend in amplitude)
- A morphing, bipolar beat syncable LFO

The envelopes all feature a continuously variable response curve, ranging from logarithmic through linear to exponential, and each stage can be as snappy as 0.3 ms to as lengthy as 20 seconds.

When set to Burst mode, the channel generates a rising or falling burst of pulses, with full control over the length of the pulse burst, the number and shape of the bursts within it, and whether the bursts increase or decrease in amplitude over the burst.

AD, AHR, Cycling and Burst modes all feature a user-selectable maximum output level of either 5V or 10V.

LFO mode offers control over the frequency and waveshape, while providing a unique morphing feature that creates numerous variations of the selected waveshape. LFOs can be either free-running or beat-synchronized using the channel's TRIG input.

Channels can be chained together to create complex multi-stage envelopes, with each channel triggered by the previous channel's trigger input, end-of-rise, or end-of-fall. This enables multiple function generators to fire simultaneously, or it enables the creation of complex multi-stage envelopes by allowing the linked function to fire either at the end of the previous function's rise time, or at the end of its fall time.

Four freely-assignable, step-attenuverted CV inputs are capable of modulating any or all of the various parameters across all four channels using the built-in CV matrix, and built-in attenuversion for each assignment.

Quadrax remembers its current state (Mode and CV assignments, channel links, etc) and retains that state even if power is removed, meaning Quadrax will always turn on in exactly the same state as you last left it.

Notes: Pico DSP is a small brother of the popular stereo effects processor Black Hole DSP. It contains eight algorithms, in detail four delays, two types of reverb, Leslie speaker emulation and an Overdrive/Bitcrusher. Each effect is editable in two parameters. One of them can be modulated using the CV input. Pico DSP features clear, high-resolution sound. Alongside the established standards, it is also possible to generate lots of freaky special effects.

Notes: Stmix is a compact 4 channel stereo mixer with an Auxilliar input. This input will allow us to chain a few of them or to insert an extra fifth input.

This module is compatible with our Hexmix system, and can be internally connected to hexmix module to add the output of STMIX to your main mix.

Notes: Fingered Control Voltage Generator, CV-enabled Motion Recorder, Voltage Wiggler.

The LS1 is a capacitive technology slider that will generate CV and GATE signals along with the movement of your finger on its surface.

LIVE Mode

Each time your fingers touches the slider surface a voltage is sent out the CV jack and the relevant GATE signal is also put out. Pair this with a quantizer and, you know..... The LEDs on the side of the slider will light up as the voltage output changes.

HOLD Mode

Without having your finger on the slider, press the rec/mode capacitive buttton. The rec/mode LED will light solid. Same as above but the CV value is held when you whitdraw your finger. Instant control surface for VCFs, VCAs and any other CV controllable stuff in your modular! Tap on the rec/mode again to back up to LIVE mode! The LEDs on the side of the slider will light up as the voltage output changes.

REC Mode

When you have your finger (steady or moving)already on the slider, by pressing the rec/mode capacitive button you START recording the movements on the slider. When you stop pressing the button (or you exceeds 8 seconds) the output will start 'playing' in loop what you recorded. The LED on the rec/mode button will blink fast during the recording and slower during the playback phase. If you operate again on the slider the output will be overridden with you physical intervention but the 'timing' won't be lost. To end the PLAY phase just tap on the rec/mode button again. The LEDs on the side of the slider will light up as the voltage output changes.

OPTIONS:

For each of those modes you can choose (via jumpers on the back) the CV range (0-5V or 0-10V), the orientation of the module (upside down anyone???? you possibly would like to choose where your jacks are!!!), the mode of RECORDING, internal or external (the GATE output in this case doubles as a REC button trigger, permitting you to 'sync' with some cosmic rhythm...). When the LS1 is in External GATE mode (set by the jumper on the back), regardless of whatever state you are (obviously either LIVE and HOLD will not act on the GATE signal!) the module will record the finger position as long as the GATE input is HIGH (max 5V) and will loop the recorded values as soon as the GATE became LOW again. If GATE lenght exceeds the maximum available time, the loop phase starts automatically.

Notes: Announcing the Dual Looping Delay from 4ms Company, designed by Gary Hall!

The 4ms Dual Looping Delay (or DLD) is an advanced audio processor for creative synthesis. Not a tape or analog emulation but a modern crystal-clear digital delay, the DLD combines features of delay, looping, and sample-tight synchronization for powerful and dynamic sound capture and modification. The DLD is designed to integrate seamlessly with modular time-base and sequencing devices such as the 4ms Quad Clock Distributor (QCD), etc.

What is a "Looping Delay"?
Modern looping devices grew directly from hardware digital delays of the late 70s and early 80s. A looping delay, modelled on units such as the classic Lexicon PCM42, has the very long storage times associated with dedicated looping, but without triggered record and playback functions.

By default, a looping delay records and plays continuously, though recording can be suspended at any time with Infinite Repeat. Sustain of delays and loops is mainly accomplished with regeneration, allowing an organic, evolving approach to sound creation as new material replaces old, more or less gradually. The 4ms Dual Looping Delay also provides advanced clock input and output facilities that allow for locking delayed and looped material with sequencers and rhythm devices of all descriptions.

The 4ms Dual Looping Delay is conceived and designed by Gary Hall. Implemented and manufactured by 4ms Company

Notes: Gritty drum voice module based on new old stock Yamaha FM synthesis chips, also capable of a decent range of synth tones. User-friendly knobby interface with a decent range of CV inputs for modulation.

Supplier's notes:
'Akemie's Taiko' is an authentic complete FM synthesis based drum voice created using original Yamaha IC's. It builds on the same technology used in the mighty Akemie's Castle but in a more complete triggered voice form featuring both signal generation and envelope shaping.

The module provides CV and direct control over a number of FM parameters including algorithm selection, operator release envelopes, ratios, waveforms & feedback. This gives a massive range of unique sounds.

The voice is able to track 1 volt per octave allowing it to be used for melodic lines as well as percussion. Also optional 'frequency ramps' can be enabled for additional audio effects.

The drum voice includes a trigger input as well as accent and choke trigger inputs to add further expressive and rhythmic control.

Notes: Mix is a 4 channel mixer that is great for audio or control voltage signals. Up to four inputs can be combined to a single output each with its own level control.

Notes: If we're honest we don't really understand fractals. Something to do with maths, apparently. But that doesn't really matter because we do understand this sequencer module, which is ideal for randomly twisting and morphing sequences.

Supplier notes:
Bloom is a fractal sequencer capable of generating infinitely evolving melodies with a host of musical features.

At its core is a powerful 32 step sequencer with two independent channels and an intuitive interface. What makes the Bloom come alive are its fractal algorithms which can transform existing sequences into powerful melodies, or even generate new patterns altogether. The base sequence is known as the Trunk and can be programmed by hand, or automatically generated with the Mutate function. Once a Trunk sequence is in place, fractal transformations are only a knob turn away by using the Branch and path controls. Each new Branch adds a complete variation to the base sequence and Path determines its passage through the set of recursively generated sub-sequences, offering a unique take on the melody with each turn of the knob.

Bring your sequencing to life with Bloom.

Notes: The ‘Pip Slope’ (rev II) is a compact envelope and function generator. It supports both Attack/Decay and Attack/Sustain/Decay type envelopes with both direct and voltage control of Attack and Decay times. Envelope shapes can be morphed between exponential, linear and logarithmic type slopes. Envelopes can be made to loop, repeating infinitely or decreasing with time or amplitude for echo and bouncing ball type effects. An ‘End of Cycle’ trigger output further extends the envelopes functionality for both clocking and burst or fill type effects.

The improved Pip Slope adds a number of new features and updates over the original Pip whilst keeping the same size. Improvements include increased output resolution, finer control of fast envelopes, a new morphing shape control, switchable 5v or 8v maximum envelope level, additional loop modes and an additional trigger output.

Features:
Compact envelope and function generator in 4HP.
Trigger and gate inputs.
Voltage and direct control of attack and release times.
Snappy or super long envelope times – ranging approx 1ms to 7 minutes per stage.
Optional self looping ability with 3 different loop modes: Decreasing amplitude, decreasing time, and regular loop.
Shape control that morphs the envelope shape from logarithmic to linear to exponential curves.
End of Slope trigger output that fires a trigger at the end the envelope or loop cycle.
Selectable 5v or 8v max envelope level output.
Reverse polarity protection.
Skiff friendly.
Designed and Made in the UK.

Technical Specifications
Supply: +12V 30mA / -12V 10mA
Size: 4HP
Depth: 38mm

Notes: Pressure Points is a controller module, an analog sequencer that is played by hand. Touching the gold plated copper wires (aka Touch Plates), you become part of the circuit, generating a gate signal (Gate OUT), a control signal proportional to the amount of pressure applied (Press OUT) and the 3 Tuned Voltages for the activated Stage.

Notes: The "WoggleBug" is a random voltage generator, originally designed by Grant Richter of Wiard Synthesizers. It is a continuation of the "smooth" and "stepped" fluctuating random voltage sources pioneered by Don Buchla within the Model 265 "Source of Uncertainty," expanding it to include the other-worldly Woggle CVs (stepped voltages with decaying sinusoids edges).

The Wogglebug is a very musical random voltage generator where it is possible to synchronize all random signal to a Master Clock. Guaranteed to unleash your synthesizer's ID MONSTER!

Notes: A-180-9 is another simple but useful tool. It can be used to connect up to 14 signals between different cases by means of standard network cables (RJ45). These cables are available all over world smoothly in different lengths and colours. From the factory two black network cables with 0.5 m length are enclosed.

The upper network connector is wired to the eight sockets 1-8, the lower to the six sockets A-F. That way it's possible to pre-patch different cases and connect signals, that are required in all cases (e.g. clock, start/stop, master CV) by means of one or two cables only instead of 14 individual patch cables. When only eight signals are required only the upper network connector is required and the sockets 1-8 are used. When more than eight signals have to be patched both network connectors have to be used. It's also possible to wire the upper and lower network to different cases (i.e. signals 1-8 to external case #1 and signals A-F to external case#2).

The module is fully passive (no power supply required) and simply wires the 14 sockets to 14 pins of the network connectors.

The A-180-9 comes in pairs for combining two modular systems.

Notes: A-135-2 is a miniature version of the A-135-1. Behind a front panel with 8 HP only four linear VCAs (voltage controlled amplifiers) and a voltage controlled mixer based on the VCAs are available.

Controls, In/Outputs and Functions of each VCA:

- Level (manual control of the VCA amplification), small rubberized knob (L1...L4)
- Control voltage input with associated attenuator (CV1...CV4), for the full VCA control range about 0...+5V control voltage are required (attenuator fully clockwise), for higher control voltages the attenuator is used, the attenuators are without knobs, just plastic shafts with white marker
- Signal Input
- Signal Output
- All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. to control the level of LFOs or envelopes)
- The signal input is not equipped with an attenuator. But the VCAs can process all signals up to 15Vpp / -7.5...+7.5V without clipping. In case of higher levels an external attenuator is required (e.g. A-183-1).
- The available amplification range is 0...1, the maximal amplification is 1 (i.e. it "clips" and remains at 1 even if the control voltage goes beyond the value that corresponds to amplification 1)

Functions of the voltage controlled mixers:

- Two outputs ("Selected" and "All")
- Selected output: the ouput if a VCA is removed from this sum signal when a plug is inserted into the corresponding VCA output.
- All output: sum of all VCA outputs, regardless of inserted plugs into the VCA outputs
- The maximal amplification is about 0.6 to avoid clipping at the mixer outputs (otherwise the outputs may distort with 15Vpp signals at each signal input and full amplifications)

Special functions of the voltage controlled mixers (selectable by internal jumpers):

- Dual Stereo VCA: In this case the control unit of VCA1 (L1 + CV1) affects also VCA3 and the control unit of VCA2 (L2 + CV2) affects also VCA4, the control units of VCA2 and VCA4 are out of operation
- Quad VCA: In this case the control unit of VCA1 (L1 + CV1) affects all four VCAs. The control units of VCA2, VCA3 and VCA4 are out of operation. In this mode the module has the same function as module A-132-2. That's why module A-132-2 will be discontinued.
- Normalling of the signal inputs: by means of internal jumpers signal input 1 can be normalled to signal input 2, signal input 2 to signal input 3 and signal input 3 to signal input In 4. That way the same input signal can be distributed to four different channels by means of control voltages (e.g. quadrophonic distribution of audio signals). Suitable control voltage sources are e.g. A-144 (Morphing Controller) or A-143-9 (Quadrature LFO).

Notes: Mix is a 4 channel mixer that is great for audio or control voltage signals. Up to four inputs can be combined to a single output each with its own level control.

Notes: Record. Mangle. Destroy.

Nebulae is a granular sampler and DSP platform. Its phase vocoder audio engine provides elastic audio, which can be time stretched, granularized, and mangled to no end. With independent control over pitch and speed, and granular controls such as overlap, window, and density, finding new sonic territory is only a knob turn away. Nebulae can use live audio input, a recorded buffer, or audio files as the source material for its powerful audio manipulations. The live input buffer can record up to five minutes of stereo audio at 48kHz, 24 bit. In addition, up to 75 MB of stereo audio can be loaded simultaneously through the USB port. No naming convention or special formatting necessary; just plug and play.

Nebulae lives a double life as an open source DSP platform with an extensive library of off the shelf alternate instruments. You can turn the module into a lush reverb, spectral delay, or tape-style looper simply by loading a new file onto the flash drive. Do you want to tweak one aspect of an existing instrument, even the default functionality? No problem. No prior coding knowledge is necessary to tweak and refine existing firmware to your liking or start with one of our templates. Alternate firmware files can be written with Pure Data, Csound, SuperCollider, and even bare-bones C programs.

Notes: Module A-160-2 is an enhanced version of the standard clock divider A-160. The module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses. The Clock input will take any digital signal from, eg. LFO, MIDI sync, or the gate from a MIDI-CV interface. At the outputs, you have access to three sets of seven different sub-divided clock signals, from half the clock frequency down to 1/128. The low/high levels of the output signals are 0V and about +10V.

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

These are the most important features of the module:

Three different sets of dividing factors, selected by a three-position switch at the front panel:
- Power of two: 2, 4, 8, 16, 32, 64, 128
- Prime numbers: 2, 3, 5, 7, 11, 13, 17
- Integer: 2, 3, 4, 5, 6, 7, 8

Two output modes, selected by a two-position switch at the front panel:
- Gate mode: outputs act like the outputs of typical binary dividers
- Trigger mode: in this mode the outputs are AND-wired with the clock signal (i.e. the clock pulsewidth affects the pulsewidth of the outputs)
- Clock edge type selected by a jumper on the pc board:
- Positive: the rising edge of the clock signal triggers the state change of the outputs
- Negative: the falling edge of the clock signal triggers the state change of the outputs

Reset behaviour by two jumpers on the pc board:
- Level triggered: the level at the Reset input triggers the Reset
- Edge triggered: the edge of the signal at the Reset input triggers the Reset
- Positive: a high level (> 2.5V) or the rising edge at the Reset input triggers the Reset
- Negative: a low level (< 1 V) or the falling edge at the Reset input triggers the Reset

Output polarity selected by a jumper on the pc board:
- Positive: non-inverted outputs
- Negative: all seven outputs are inverted

Notes: Belgian analogue innovators Joranalogue serve up an ultra-versatile filter module. Multimode flexibility meets self-oscillation for added sonic versatility. A hell of a lot of filter for the money.

Supplier's notes:
Representing the cutting edge in modular analogue voltage controlled filter (VCF) design, Filter 8 offers more possibilities and higher fidelity in 12 HP than ever before.

Starting from the classic OTA-style 4-pole cascaded lowpass (LP) topology, Filter 8 features separate LP outputs, each with their own character. Additional filter responses are achieved by pole mixing: 1-pole highpass, a special band boost and notch response, phase shifter and 4-pole bandpass. All outputs are available simultaneously.

Key to Filter 8's performance is the innovative resonant feedback circuit. By increasing the resonance, all outputs will resonate at the filter frequency, without any low frequency response loss. At higher resonance levels, self-oscillation is achieved, turning the module into an excellent 8-phase sine wave voltage controlled oscillator (VCO) with temperature and switchable gain compensation, low distortion, constant amplitude and accurate frequency tracking over at least 5 octaves. At sub-audio frequencies, Filter 8 can function as an 8-output voltage controlled slew modifier or 8-phase low frequency oscillator (LFO).

Simultaneous exponential and linear frequency modulation is possible, for classic FM tones or chaotic modulation. A hold feature is also provided, 'freezing' the output voltages manually or under gate control. This is useful for halting modulations, or as a sync-like effect at audio frequencies. The dedicated 'ping' input allows you to easily create crisp percussive sounds with different timbres.

While rooted in the legacy of classic synthesisers, Filter 8 provides a new approach to musical signal generators and modifiers: instead of simply a VCF, VCO, slew modifier or VCLFO, a single analogue module can now be any of those, and anything in between.

Notes: Polyphony is back!

Chord v2 is a plug and play solution for bringing musical polyphony to your system. It contains four oscillator voices, a multitude of waveforms, and intelligent tuning functionality. This new version features an expanded sonic palette and feature set in half the size of the original.

It features three primary modes of operation: Chord, Free Running, and Unison. These three modes allow the oscillators to be tuned as diatonic chords, run independently of each other, or be tuned to the same internal frequency for external v/oct sequencing through independent CV inputs.

The timbral possibilities of the Chord v2 bring its polyphonic tones to life. The module ships with eight banks of waveforms encompassing traditional shapes, vocal synthesis, organ emulation, and chiptune sounds. You can also load custom wavetables using the SD card slot on the front panel.

From harmonic drones to Switched On Bach, the Chord v2 is an unparalleled addition to any Eurorack modular.

Changes from v1:

- Half the size! 14HP down from 28HP
- Eight banks of waveforms
- Full polyphonic mode
- Harmonize in minor mode
- Custom wavetable compatibility
- Expanded chord types
- Improved synthesis engine

Notes: Stereo compressor in only 4HP!
The module was mainly designed as a dynamic tool for subgroups and sums, but also works well with single signals. Similar to classic DBX units, threshold, ratio and gain can be adjusted with just one knob. Further fine adjustments can be made for attack and release times. In addition to compression, the module can also be used as a limiter. Ducking effects can be created via a sidechain input.

The MSCL is equally suitable for subtle and strong compression effects. Ratio (1.25:1 to infinity), make-up gain and threshold can be adjusted with a single potentiometer. The threshold works in the opposite direction as the other parameters. In addition, there is a threshold switch that can be toggled between three value ranges (-15 dBu, -4 dBu, +5 dBu). This allows the MSCL to be used with other audio signals outside the modular system. In addition, it is possible to limit the gain control range by 3 dB or 9 dB. This makes the module behave similar to a peak limiter. The attack and release controls can be used to adjust the settling phase and the decay time of the compressor. At the output, it is possible to increase the gain by up to 35db. With the switchable sidechain channel, the MSCL can also be controlled by external signals.

Features:

Sidechain input for classic ducking sounds
Easy and intuitive design
Threshold switch lets you compress modular level signals as well as lower level sources
Limit switch limits the makeup gain on the comp knob to make compressor act more like a peak limiter
Power consumption: 50mA at +12V and 50mA at -12V

HP : 4

Notes: Successor to the excellent Metropolis, the Metropolix is a performance-focussed step sequencer with some really neat features, including modulation and sub-sequences in Loopy mode.

Supplier's Notes:
The Intellijel Metropolix is a unique and powerful Eurorack format musical sequencer. With an abundance of hands-on, tactile controls and a wealth of modulation possibilities (both internal and external) you can quickly and easily create infectiously musical sequences that are never boring. Even the simplest riff can be brought to life with seemingly endless options to create variations or real-time manipulations. Equally at home in the studio or a live improvised performance, the Metropolix is sure to become a staple source of fresh ideas and killer riffs in your creative process.

Width: 34HP
Depth: 25mm
Power: 95mA @ +12V 10mA @ -12V

On first blush, it appears to be a simple 8-stage sequencer - but there is far more functionality than first meets the eye:

There are two tracks (TRK 1 and TRK 2) that are variants of the single master pitch/gate sequencer, which is programmed via the PITCH sliders, PULSE COUNT and GATE TYPE switches. Each track interprets the master sequence in a variety of ways - creating complementary sequence variations that enable you to generate counterpoint, polyrhythms, and all manner of sonic movement (both subtle and extreme). Each of these tracks has its own playback ORDER, sequence LENgth, clock DIVision, SWING amount, SLIDE time, and track GATE lengths. Other track-based sequence variables are accessible from the TRACK MENU, and include Pitch Slider inversion; sequence note range; track transposition; and more. In addition, Tracks 1 & 2 both have multiple lanes of per-stage playback parameters, including: GATE override; PITCH override; RATCHet count; PROBability of playback; ACCUMulating transposition, and a dedicated CV lane. Each stage also has a SKIP feature, and a pitch SLIDE option.

8 separate and individual MODulation lanes are accessed via the MOD button. Each MOD lane has 8-stages of modulation values and its own playback ORDER, LENgth, and clock DIVision; and each lane is routable to one of Metropolix' two assignable outputs or to dozens of internal destinations, allowing for some sophisticated and powerful self-modulation.

A trio of AUX inputs allows for external modulation of user-assignable sequencer parameters for even greater variation, while two assignable CTRL knobs give you direct access to the parameters you want to adjust most frequently during a performance. With dedicated Pitch/Gate outputs for both Track 1 and Track 2; two totally user-assignable outputs (A and B); and internal MOD routing, Metropolix features a wealth of patching opportunities.

Metropolix also features a Loopy mode, allowing you to instantly play back short sub-sequences, or even "play" the stage buttons directly (like a 'keyboard').

Metropolix stores up to 64 preset configurations (in 8 banks of 8 presets), and all live settings are stored in EPROM, ensuring that your Metropolix will always power up exactly as you left it - even if you haven't saved them to a preset. By default presets can change all the structural (menu-based) elements of your sequencer without overwriting the front panel controls, but full recall is also available.

The operation of the Metropolix is optimized for live performance and jamming, with quick access to all the most important performance parameters, and the ability to greatly affect your sequences with a single slider or switch.

Notes: Nicely thought out four-voice sample playback module from Parisian innovators Squarp. Load up a microSD card with samples (up to 2600 kits), then trigger and process. Neat.

Supplier's Notes:

Rample waves system

Eurorack 4-voice sample player & audio processor

Versatile sample machine

From percussive drum-machine kits to synth samples, breakbeats to sound FX, backing tracks to hour-long audio music, Rample can play up to 4 .wav files on independent audio outputs :

These samples are stored inside the provided SD card, and organized as kits, from A00 to Z99... allowing up to 2600 banks of 4 voices, with on-the-fly loading! The SD card is preloaded with tons of samples, and we made it very easy to import your own kits.

Thanks to the DC coupled audio outputs, it's also possible to play CV waveforms.

Effects rack

Each voice has its own "rack" of effects, and all audio effects can be enabled at the same time, allowing you to manipulate your samples in real time, from a gentle lowpass to massive destruction!

pitch - a great sounding pitch engine, based on a 6-pole interpolator, which ranges from -1 octave to +1 octave.

bits - two different bitcrushing algorithms, based on sample rate and resolution reduction. It produces distortion and warms the audio signal.

filter - a low resonance filter, DJ-style, cutting off the high frequencies or the low frequencies.

freeze - sample and loop a fraction of the played waveform, creating a glitching effect.

levels - decrease the gain or drive the signal.

It's also possible to edit 'advanced parameters' like the start point, sample length, attack/decay and run mode, and create mute groups without breaking a sweat.

Finally, thanks to the 4 CV inputs, any of the effects (or advanced parameters) can be assigned to create amazing modulations!

Multi-layer sampling

One of the key feature is the ability to "multi-sample" your kits, multiplying Rample's potential. Each voice supports up to 12 samples, can be played randomly or in a controlled fashion. It's a great way to add complexity and variations, to create organic/acoustic sounding drums, or simply to increase the number of samples per kit (up to 48).

As an example, Squarp are providing a multi-layered drum kit, with 12 different recordings of a kick, 12 different recordings of a snare, etc. Sequencing them randomly leads to a more natural drum playing.

Another kind of multi-layered acoustic drum kit is also provided, where each drum is recorded with 12 levels of velocity. Controlling the layer to be played leads to intricate, convoluted drums programming.

Of course, it's very easy to create your own multi-layered kit, and you can use this method to perform multiple synth chords, sound glitches, voices, breakbeats, ...

CV/Gate and Midi interface

Rample is designed to be the perfect rhythmic companion of your eurorack system thanks to its Gate (trig samples) and CV (modulate samples) connectivity.

You can also use it as a standalone midi machine, without using the CV/Gate connectivity: the midi in port allows you to trig & control all samples parameters + effects values at the same time. Each Rample comes with a 'stereo jack to midi DIN' and 'stereo jack to jack' adapters, easing the chaining of multiple modules in order to create an 8-voice, 12-voice, 16-voice (or more) midi drum machine!

SD card preloaded with 200+ kits from artists and sound designers, covering a large range of audio samples

Notes: Pluck is a physical modelling synth voice. It uses the Karplus-Strong algorithm to create plucked string sounds. The dampening control sets the size of the string and allows for dramatic timbral shifts.

The decay control changes note length from percussive transients to infinite harp sounds. In addition, four voice polyphony provides complex layered tones; all from a single sound source.

Strum a new chord with Pluck.

Notes: This is a simple 1U module designed to allow the monitoring of a system using headphones. However, if your cat isn't easily scared, the headphone jack doubles as a TRS stereo line level output. Simply connect the signal that you want to monitor to the 1/8? jacks, plug in your headphones, and adjust the volume as desired.

Notes: The Listen IO is a simple module which gets signals in and out of a Eurorack system by converting to and from normal modular levels. The top section converts any external signal to modular levels by providing up to 30x gain (+30dB), allowing you to use table-top synthesizers, keyboards, phones/tablets, computers, toys, microphones, etc. in your patches. The bottom section does the opposite: modular signals are converted to normal line level signals. The bottom two jacks can be used as line outs or as headphone jacks, so you and a friend can listen in stereo at the same time.

Each section has two inputs and outputs for use with a stereo signal or two mono signals. An LED bar graph for each output shows the signal level and clipping.
