Synth modules

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: 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.

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.

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

Notes: Tallin is a dual voltage controlled amplifier (VCA) with overdrive, offering some unusual control features and a range of attractive tonal characteristics. Each of the two identical channels offers two simultaneously available inputs for voltage control over signal attenuation or gain, with linear and exponential response to CV. Volume control knobs offer manual gain settings ranging from fully closed (-80dB) up to +18dB. A colour LED indicator displays output signal levels. A soft-clip circuit avoids harsh clipping distortion, while a switchable overdrive circuit offers two carefully crafted distortion responses, simulating the sound of classic tube amplifiers.

Since both CV inputs are simultaneously active, they can be jointly exploited within patches featuring more complex volume control that otherwise would require using two traditional VCAs in series. As the signal path is DC-coupled, Tallin can also be used for handling the control voltages.

Notes: Row Power is a clean, regulated, and protected power solution for Eurorack systems. Row Power 45 provides enough power for two to three typical Eurorack rows (typically up to about 312HP):
+12V @ 2.0A maximum, 1.5A recommended
-12V @ 1.4A maximum, 1.2A recommended
+5V @ 1.5A maximum, 1.2A recommended

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying bus cables or the Bus Stick. For custom power systems, the Row Power 45 has a set of easily soldered holes for using large gauge wire or MTA156 connectors to connect to distribution bus boards.

Multiple Row Power modules can be powered from a single power brick by daisy-chaining with an inexpensive barrel cable. The Row Power 45 can also be daisy-chained to 4ms Company's Pod enclosures. Each power supply is independently regulated and protected for ultra-low cross-talk between rows/pods.

The Row Power 45 is compatible with the 4ms Row Power Shield. This device (sold separately) attaches to the back of the Row Power 45 and monitors the amount of current being drawn, as well as the voltages of the power rails. The information is sent over Bluetooth to be displayed on a phone or tablet.

Notes: The Mutant Brain is the central nervous system connecting your modular analogue eurorack system to MIDI gear, especially for percussion, polyphonic notes and sync duties! It packs 16 eurorack compatible outputs into a tiny, super affordable 8HP package.

The 4 CV outputs and 12 Gate/Trig outputs are all universally reconfigurable. Triggers, gates, clock divisions and sync signals, polyphonic keyboard playing, velocity, sequencer transport, LFOs - you name it!

Configuring your patch is easy - just assign each output as you like in the Mutant Brain Surgery configuration utility, then send the MIDI SysEx file to the module and forget about it - the Mutant Brain remembers it all for you.

Hexinverter supply a convenient download pack of pre-configured, ready to use Mutant Brain patches for some select sequencing and drum machine devices on the market today, easily turning those sequencers and drum machines into a modular control powerhouse!

Designed with live and studio performance in mind, the Mutant Brain does away with wasted panel space and complex menu-diving interfaces, while freeing you from the limited "auto-learn" type MIDI interface. An auto-learn interface sometimes doesn't play well with the limitless combinations of different gear setups which today's modular performers play live with.

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: 32 unique audio effects arranged in 4 banks of 8 effects. Three effect controls plus analog Dry/Wet control with dedicated CV input. High quality stereo signal pass. Assignable CV input to effect controls or to Sample Rate reducer (changes internal clock). Four user storable presets - stores selected program and all three controls. Spin FV-1 based.

The last used effect, assigns and presets are always remembered.

32 effects are simultaneously available, but FX AID can be reflashed with other user selected Happy Nerding effects in any order. Also the possibility to run freely available third party effects will be added too.

Reflashing procedure is quite easy: playing 40 sec long "wav" file of line level amplitude to CV input.

Reflashing mode: hold both buttons for 10 sec.

Please note the reverse CV operation of the Dry/Wet control: positive CV crossfades from Wet to Dry, and negative CV crossfades from Dry to Wet.

By default it runs on 32.77 kHz and, if sample rate reduction assign is used, this sample rate can be decreased down to 150 Hz or brought up to 48 kHz.

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

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

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

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

Notes: 'MUM M8' is an 8hp Eurorack low pass filter building on the filter design used in the classic Akai S950 12 bit sampler with the addition of resonance, voltage control, clipped saturation and a dedicated VCA.

The low pass filter gives the recognisable super smooth vacuum like tone sucking sound which works magic on complex sources. The addition of clipped overdrive and intentionally aggressive self-oscillating resonance compliment the smooth filter core by juxtaposing it into more wasp like territory with acidic squeals and a more gritty sound.
Mum M8 features dual voltage control with attenuation (and inversion) of filter cut off and voltage control of resonance together with dual audio inputs - one of which includes a VCA to with the capability to aid overdriving signals into the filter core.

The filter core is a 6th Order Butterworth switched capacitor type design featuring an analog core but controlled by a high speed digital clock. This produces the characteristic smooth sounding filter but, as with the original S950, has a relatively high minimum cut off as to avoid 'clock bleed' into the filter output from the digital control. This minimum cut of point (and introduction of bleed if required) can be controlled via trimmers on the rear of the module (see calibration chapter). It is not unusual for there still to be some low-level artefacts from the clock present, particularly during filter sweeps - these add to the filters character.

The motivation for the module came from discussing filters in classic samplers with the artist Jack Adams - aka Mumdance. Jack suggested investigating the S950's filter well known as for it use in classic use in early jungle and hardcore. From that point onward Jack provided inspiration, help and feedback in the development of the filter. Big up Mumdance.

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: Versatile stereo digital filter based on Endorphin's Grand Terminal module. CV-controlled cutoff, resonance and separate high-pass filter. Simple but effective.

Supplier notes:
The Squawk Dirty To Me is a stereo filter with voltage controlled resonance. It features eight filter modes and zero-delay feedback.

- Simple and effective 6hp stereo VCF
- 8 filter modes available with meta CV scanning, famous zero-delay feedback Grand Terminal filters
- Additional hi-pass filter in series quickly cuts the boomy low end

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

Each ADSR provides these controls and in/outputs:

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

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

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

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

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

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

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

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

Notes: Verb is a lush stereo reverb with a full feature set and superior audio quality. A wide range of reverb times take your sound from small room to never-ending concert hall.

CV over mix allows dynamic movement between the dry and reverberated sound, and the dampening control lets you dial in the perfect timbre for the wet signal. Whether you need a traditional reverb for an FX send or an esoteric sound design tool, Verb can take you there. Get lost in space with Verb.

Notes: uBurst

This is a new build of the micro version of Mutable Instruments Clouds. The module retains all the functions of the original Clouds, taking up significantly less rack space.

These modules use tall bushing potentiometers to offer a more stable feel.

The module is fully assembled, tested, and calibrated. Eurorack power cable is included.

Notes: Samara is a "Swiss Army Knife" type of module, intended to serve the most common voltage and audio signal processing purposes such as attenuation, offsetting, mixing, inverting, and even basic waveshaping. Samara features four channels, each with two inputs and an attenuator, additional switchable offset generators, four voltage level and polarity indicators, two adders with switchable scale, and a precision four-channel processor that selects minimum and maximum voltage.

Notes: Loop is a high fidelity looper with four unique recording modes and an intuitive user interface. It can capture up to five minutes of audio with reverse, and half-speed playback accessible. Each recording can use one of four modes: Sound on Sound, Dub, Replace, and Infinite (i.e. Frippertronics). Whether you're looking for minimal part layering, or full blown ambient soundscapes, Loop will take your patch for a ride.

Notes: Clever four-channel utility module designed to make it easier to achieve perfect oscillator tracking and transpose CV signals. Also includes some neat quantising and portamento features.

Supplier notes:
The CalTrans solves issues encountered when playing tonal music with a modular system: tracking problems, curves unrelated to Volt per octave ratio, limited octave range, cumbersome transpose, ...

The CalTrans corrects and expands the range of troublesome VCOs and brings V/Oct tracking to anything that oscillates.

Besides calibration, the CalTrans offers live play features. Each channel can be quantized and any combination of them transposed jointly.

A pair of rotary encoders with detent allow an precise selection of octaves and semitones.

VCOs whose tracking doesn't go high enough to follow the leader will see their pitch repositioned in their highest possible octave so that the global harmony is unaffected.

You can add a pinch of portamento and glissando to each channel and save the whole in user presets.

Notes: AXON-2 is an 8HP expander module for the SQUID SALMPLE, MFX and Pamela's PRO Workout that like the AXON-1 provides 4 additional freely assignable CV inputs but additionally adds manual offset controls and 2 additional 'performance' buttons.

The addition of AXON-2 increases the Squid, MFX or Pam PRO's total number of CV inputs by 4, greatly increasing the possibilities for vast modular manipulation. Each of the CV inputs includes an offset for hands on control over parameters assigned to CV. Per assignment digital attenuation and offset via the host module is also available for fine tuning the modulation or control over parameters.

The AXON-2's large buttons are great for controlling select functions in a live performance environment or adding convenient quick navigation shortcuts when making edits. The buttons functionality and assignability are dependent on the host module. See respective manuals for details.

NOTE: AXON-2 support requires the latest firmware be installed for Pam Pro (120 or newer), Squid (187 or newer) and MFX (105 or newer).

Notes: Simple but effective output module, converts stereo instrument-level signal to balanced XLR outs. Ideal for live use but just as good for avoiding unwanted hum in the studio.

Supplier's notes:
Whether it's in the studio or on a live stage, keeping audio interconnections free from unwanted hum and interference can be a challenge. Balanced lines are the proven solution to this problem.

Conventional balanced output solutions often rely on transformers providing galvanic isolation to mitigate the effects of ground loops. Unfortunately, these components are bulky, expensive and colour the sound (often unfavourably, especially in the low end).

Instead, Transmit 2 (or TX2 for short) takes a fully solid-state approach. Offering a stereo pair of XLR balanced outputs, it ensures that the sonic clarity of your carefully planned modular system is not lost in its interface to the outside world.

Engineered to provide massive headroom while retaining extremely low noise and distortion, Transmit 2's circuitry incorporates low-impedance design practices, radio-frequency (RF) filtering and premium balanced drivers to provide transformer-like interconnect performance in a compact and affordable module. And thanks to the electrostatic (ESD) and phantom power discharge protection, it's rugged enough to survive the rigours of performing on the road.

Adjusting the main output level is a breeze thanks to the dual peak-responding LED meters. A high-end headphone amplifier is included as well, controlled by a separate level knob. It can deliver the voltage and current required to power practically any headphones, regardless of the impedance or driver technology. This 3.5 mm stereo socket can function as an auxiliary stereo line output or even drive small passive speakers, making Transmit 2 an all-round flexible answer to all your output needs.

Notes: Unusual output and mastering module, inspired by studio and radio mastering tools but fitting into just 6hp. Includes multi-band compression, mid/side stereo processing and brickwall limiting.

Supplier's Notes:
Golden Master is a multiband processor module in Eurorack format. Inspired from the studio mastering and radio loudness units from the 90's, this tool is a game changer for everyone who performs live with a Eurorack synthesizer.

The whole magic of Eurorack lies in its raw sound and simple analog mixes - processing through the Golden Master brings instant punch and sound pressure, as well as controlling the overall volume.

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

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

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

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

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

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

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

Notes: 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 Listen Four is a four channel stereo mixer with line, modular, and headphone outputs. Two mono channels with Pan knobs and two stereo channels with dual inputs provide optimal compatibility with both stereo and mono signals. The Listen Four can be daisy-chained to other Listen modules to create a larger mixer with sub-mix outputs.

Notes: Updated version of a truly pioneering Eurorack module that introduced DSP effects to the format. Still sounds great, still versatile, still excellent value.

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

Notes: User-friendly mid/side processing module. Tweak the stereo image or split a stereo signal into mid and side elements then route out to other modules for further processing before summing back together. Powerful.

Supplier's Notes:
Minsk is a stereo image processor. It is a hybrid tool that combines digital and analog processing to facilitate advanced mid/side (M/S) manipulation of a stereo signal pair. It allows for separate treatment of the mid and side components, which affects the depth and width of the auditory scene. Minsk offers both manual and voltage control of the stereo width, as well as two dimension effects for enhancing the existing stereo image or creating a faux stereo image based on the stereo or mono input source. Minsk is especially handy during the preparation of a vinyl release or before a club concert, because it can eliminate out-of-phase low-end frequencies (high pass filter at 300Hz with the filter slope 12dB/oct, 50Hz with the filter slope 24dB/oct).

Notes: Another iconic Buchla module gets the Eurorack reissue treatment courtesy of TipTop. The 242t is the brand's unique voltage-controlled clock and trigger module, generating pulses based on a 4x12 matrix.

Supplier's Notes:
The Buchla and Tiptop Audio 242t Programmable Pulser is a reissue of the time-event-based generator from the 1970s 200 series. At its center is the Pulser, a voltage-controlled clock oscillator with a wide frequency range, extending up to audio frequencies, numerous outputs, and start/stop controls. The Pulser drives a programmable matrix with three rows of up to 12 stages: (A), (B), and (C). Stages are activated using the X/Y coordinate controls, and the total number of stages can be set using the (n) row. Clock and Reset inputs allow the 242t to sync with other devices, while the Reset input can also be used to control the number of stages with external pulses.

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

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

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

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

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

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

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

Notes: Alan (micro Turing Machine) Shift Register Based Sequencer

The randomness of the Music Thing Modular Turing Machine, shrunk down to 6HP. Alan retains all of the same functionality as the original including the connectors for the expanders.

While this module has little to do with the original Turing Machine (by Alan Turing), it is a shift register based sequencer. You cannot program this sequencer, instead it builds random sequences that can be locked in.

Alan comes tested, calibrated and ready to bring random voltages.

The After Later Audio panel is black and gold and made from FR4. The package will include a power/ribbon cable and a one year warranty.

Notes: EME (Eloquencer MIDI Expansion) is the perfect companion for the Eloquencer, adding capabilities to sync with MIDI devices, control most of the eloquencer parameters with MIDI interfaces, generating MIDI voices from the eloquencer tracks, and converting MIDI signals to the eurorack world.

Description:
MAIN FEATURES
IN / OUT
DIN-5 MIDI Input, DIN-5 MIDI Output, USB Host.

BUTTONS
4 freely assignable buttons. They can be assigned to:

Next/previous pattern
Next/previous part
Direct access to Pattern mode, Play parts, Duplicate, Project, Gate REC, CV Key REC, MIDI key REC, Free Play...
Save current project
Random 1 to 3 layers of selected track
Reset LFO of selected track
On/Off LFO of selected track
Freeze
Revert
Fill A to H or selected track
Mute A to H or selected track
DJ Nudge FWD/BCK fine/coarse

MIDI CLOCK
Eloquencer can receive 24ppqn sync from MIDI device from its DIN-5 MIDI Input, and can send 24ppqn MIDI clock through its DIN-5 MIDI out.
When working as 'internal' it will send the internal clock to the MIDI output.
When working as 'external' will send the eurorack incoming clock to the MIDI output transformed into 24ppqn.

MIDI OUT
The Eloquencer tracks can be independently assigned to:
- Voice events (note on/off, velocity, ch pressure...) For example Track A can be assigned to Channel 1 Note on/off and Track B can be assigned to Channel 1 Velocity, so track A gates and CV control Channel 1 notes and pitch, and track B controls Channel 1 Velocity.
- Control Change (CC)
- Program Change (PC)

The gate and CV output will work as usual when a MIDI OUTPUT is assigned, so voices can be doubled using the modular and an external synth.

There's a particular execution order for MIDI out events, so the first to be launched is the Program Change, followed by the CC and then the voice events. This way, we can launch program changes before the note on message is received allowing preset changes for each step.

MIDI IN
Both, the DIN-5 MIDI in and the USB can be used to change eloquencer parameters using controllers or to introduce notes in REC MODE using a keyboard.

There are 3 different groups of controls associated to MIDI channels:
- Channel : 8 MIDI channels to control parameters of specific tracks from A to H
- Global : 1 MIDI channel to control Global parameters.
- Focus: 1 MIDI channel to control the parameters of the currently selected track (track in focus). That means that if Track A is selected and we send CC 38, we will be shifting track A, but if we select track B and we send the same CC 38, we will be shifting track B.

When using the USB host input, the EME can send feedback information in case the controller that is being used has LEDs to be updated.

There is a big amount of eloquencer parameters that can be controlled using an external MIDI interface / controller. For example:

Non-destructive track parameters addition/subtraction (CV, CVP, CVR, GL GLP, R...)
Track length
Step mode / Step mode DIV / Step mode REP
Track shift
LFO on/off / Type / Length / amplitude.
Fill
Mute
Random
CV Gate link
Scale group and root
Tempo
DJ Nudge
Shuffle
Clock out
Play / Stop
Direct access to modes (Pattern, Project, Live REC...)
MIDI INTERFACE

A MIDI Channel can be assigned to an Eloquencer Track, so the gate and CV outputs will stop listening to what is sequenced and start listening all note on/off messages coming from the chosen MIDI channel.

Notes: Part of Xaoc's Leibniz subsystem, which processes signals and voltages by manipulating binary 8-bit numbers, the Poczdam allows switching between two data sources.

Supplier's Notes:
Poczdam is a binary data routing solution for the Xaoc Leibniz Subsystem. It facilitates manual and remote switching between two Leibniz data sources, modifying individual bits of the data stream, and re-clocking the data with its onboard voltage-controlled wideband oscillator or any external clock signal. Poczdam is particularly useful within complex Leibniz setups where the user needs to reconfigure the data flow between multiple modules. However, it can also be employed in small creative patches, e.g., for waveform splicing, disrupting rhythmic loops, or generating digital chaos.
To better understand the device and avoid common pitfalls, it is strongly advised to read through the entire user manual before use.

Drezno is the input/output front-end of the system, consisting of an analogue-to-digital converter (ADC) and a digital-to-analogue converter (DAC), that alone can be used for manipulating analogue signals and voltages based on their binary representation.

Lipsk is a binary logic processing expander module that can flip (invert) individual bits of the digital signal representation. There are more Leibniz Binary Subsystem elements coming, with specialized and advanced sets of features.

Jena is a digital module that may be used as a flexible waveshaper for CV and audio signals, a wavetable oscillator, a Walsh function generator, or a rhythm generator.

Erfurt is a bi-directional digital counter, frequency divider. It has multiple applications: the output of the counter may be used as a phase source driving a digital wavetable, connected to other Leibniz modules it may scan waveshapes in Jena, produce stepped voltages useful for making interesting glissandi with Drezno and any VCO, generate gate patterns animating the spectrum of Odessa harmonic banks, spawn pseudo-chaotic sequences when fed back to Lipsk, etc.

Notes: Add external feedback loops, tilt filters and more to the Timiszoara effects module with this versatile expander. A must-have for Timiszoara owners.

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

Notes: Module A-108 is a completely new voltage-controlled low pass filter based on the well-known transistor ladder (Moog ladder). The module has internally an 8-stage low pass filter with different slopes available: 6, 12, 18, 24, 30, 36, 42 and 48 dB per octave. In addition, it features a band pass output (i.e. band pass with transistor ladder). In the factory, the 4 low pass outputs of the A-108 are internally connected to the filter stages 6, 12, 24 and 48dB.

Resonance (Emphasis or Q) can be adjusted manually right up to self-oscillation, in which case the filter will behave like a sine wave oscillator. The A-108 features an external feedback input that enables the insertion of additional modules into the feedback path (e.g. VCA for voltage-controlled resonance or phaser/frequency shifter for phase/frequency shifting effects). The socket is normalized and internally connected to the 48dB low pass output if no cable is inserted into the feedback socket.

The frequency can be adjusted manually, or by voltage control. Three CV inputs (CV1, CV2, CV3) are available. CV2 and CV3 are equipped with attenuators.

The filter audio input is very sensitive so that distortion - if desired - is possible even with normal A-100 levels (e.g. VCO output). Self-oscillation will break off at high distortion levels as the internal feedback signal is drown out by the distorted audio signal. This feature may intentionally be used to create new sounds.

In combination with the Voltage Controlled Mixer A-135 and the Morphing Controller A-144 a filter with voltage-controlled slope can be realized (i.e. controlling the slope from 6dB to 48dB via CV).

Notes: An 8hp version of the retired Mutable Instruments Grids. It is an identical functional clone, so it will behave in the same was as the full size version, and will run any firmware that runs on the full size version.

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

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

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

Notes: Stereo Strip takes the idea of a channel strip and makes it modular. By bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters, you will find new, creative ways to use it in your patches!

It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.

Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.

The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!

Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.

Notes: The Flame u16MCC is a compact MIDI interface, which converts received MIDI control change commands on 16 outputs into CV voltages between 0 and + 5V. The resolution of the data bytes is 7bit. The outputs each have a passive lowpass filter, which smoothes the output voltages.

Each of the outputs can be assigned a separate control change number between 0 and 127 on its own MIDI channel. The module is programmable via the LEARN function with a MIDI keyboard and MIDI controllers, or via SYSEX commands. Some SYSEX files with default settings already exist.

The module has two MIDI sockets (mini jacks in TRS-B standard) INPUT and THRU. The data received at MIDI-IN is forwarded via MIDI-THRU. Additional MIDI modules can then be connected there.

Notes: The Z4000 NS is a snappy voltage-controlled analog envelope generator with a built-in CV processor for scaling, inverting, and voltage-controlled deviating of the envelope shape. The Z4000 generates an envelope made of the four classic segments: Attack, Decay, Sustain and Release, in which each segment can be manually set using knobs or dynamically set under voltage control.

Control knobs for the Attack, Decay, and Release segments are scaled. The first 0-50% of the knobs rotation is dedicated to high resolution adjustment in the millisecond range.

The output levels are fully adjustable with signals that can reach up to 10V in either polarity and can be mirrored into the opposite polarity or clipped using the voltage-controlled deviater-scaler. A bi-color LED indicates intermediate values in both polarities and their crossfade state.

The Attack slope switch allows selection of a logarithmic or exponential curve for the Attack segment. This subtle effect helps further the fine adjustment of the Attack segment slope. A Shoot button is provided to let you fire the envelope manually. The Z4000 also provides a retrigger input allowing you to create legato notes when using a classic keyboard interface.

Going down to nuts and bolts, the Z4000's smoothness and snappiness is made possible by a four segment active-charge discrete circuit which is an extended version of circuits found in classic two segment rise / fall transient generators.

Notes: Gera is a component of the Leibniz subsystem that allows masking individual bits of the digital data by the use of logical AND operation.

It features 8 individual gate inputs that affect the individual bits of data, as well as 8 illuminated tact switches for manual inverting of each control input. When connected to Drezno that is processing a waveform or voltage, masking of individual bits yields various forms of quantization. However, Gera can function on its own. The AND operation is a basic building block for sequence automation, chaos and rhythm generation, and various computer-like modular patches.

Bit processing logic in Gera is hardware based, hence there is virtually no latency, and the binary signals may change at extreme rates.
