Notes: On the surface, Xaoc Devices Berlin is a simple compact VCO offering square and saw waves with hard sync, FM input and octave switching. The most interesting part lies behind the panel and that is the Leibniz Binary Subsystem interface, namely LBZ out and LBZ in. The front panel LBZ LINK button and its corresponding gate input switch between the default saw wave and a signal that has been passed through any Leibniz module (or a combination of Leibniz modules) connected to Berlin. Add Xaoc Devices Jena for wave processing and the output is no longer a simple saw wave - you now have a vintage-style wavetable oscillator with a penchant for the experimental due to its open, hackable nature.

Berlin operates in a way similar to the classic PPG Wave and Fairlight CMI synths and employs a variable sample rate of an extremely wide-range internal clock. As the sample rate changes with the oscillator frequency, Berlin's internal square and saw waves exhibit no aliasing effect. The whole frequency range spans from 30 seconds in LFO mode up to 250 kHz (!) with the clock reaching an astounding 20 MHz. Add to that voltage control over all parameters and the result is a highly versatile module capable of creating a significantly diverse palette of unusual waveforms. To better understand the device and avoid common pitfalls, it is strongly advised that you read through the entire manual before using the module.

Technical details:

8hp, 30mm deep (including the ribbon cable and bracket)
Current draw: +40mA/-20mA
Reverse power protection

Connectivity:

Berlin connects to all modules compatible with the Leibniz Binary Subsystem: Drezno II, Lipsk, Gera, Jena, Erfurt, Poczdam, Rostock, Ostankino II, and Odessa.

Notes: PM DB25 MKII is an expander output for the MKII versions of the Performance Mixer and Channels.

Pre-fade and Post-fade connections are available for all channels. The DB25 has 16 outputs. All mixer channels are stereo, so one DB25 handles the main PM MKII (either pre or post), and the DB25 can handle 2x Channels (either pre or post).

Simply connect the cable to the Pre or Post headers on the back of the PM MKII or Channels MKII modules to choose pre/post.

The PM MKII has an additional header with both Aux Sends, Master Bus, and Submix Bus.

Connect a DB25 cable of your choice to the front connector and then straight to your DAW or recording interface.

For use with original WMD Performance Mixer, an adapter board can be added on. Please note that width behind panel is increased by 8mm when adapter board is added on. This may require some clever position in your case. The original Performance Mixer still only offers Pre Fader Outputs.

Notes: The LedPressor is a full stereo Diode-based compressor module.
Its unique core adds character and color to any signal passed through it.
The LedPressor can be used as a normal compressor with low input levels, but as the input volume increases and the "nuke" LED lights up, it enters a new territory that combines compressor and overdrive, creating a dynamic overdrive effect.

Get it pumping with the Side Chain
The module features an external sidechain input that accepts audio and CV signals. Only the sidechain signal passes through a high pass filter, which gives the user greater control over the sound shape. The audio signal itself is not affected by the filter.
Parallel compression
The module also includes a mix knob that can be controlled with a dedicated mix CV input, allowing for greater flexibility when blending dry and wet signals. Additionally, it features a momentary bypass button to easily adjust the levels of dry and wet signals.
Feed-Back Or Feed-Forward - it's your choice
The module can be configured with a feed-back or feed-forward topologies with a jumper in the back.
Reverse polarity protection
The module have proper reverse current and over current protection in its power input stage to protect the module in case it was connected the wrong way or connected to a faulty power supply.

Notes: This versatile dual-function Eurorack module offers both a Low Pass Gate (LPG) and a Voltage-Controlled Amplifier (VCA), inspired by two iconic designs in synthesiser history.

Low Pass Gate (LPG)

The LPG is modeled after the classic Buchla design, delivering a rich, organic sound that blends amplitude control with low-pass filtering. Ideal for producing natural-sounding dynamics, the LPG responds to control voltages to create plucky, percussive tones and smooth, woody textures. Its distinctive vactrol-based architecture provides a warm and unique character, adding depth and nuance to your patches.

Voltage-Controlled Amplifier (VCA)

The VCA draws its inspiration from the legendary Minimoog, ensuring a clean, dynamic, and responsive performance. Known for its iconic smoothness and headroom, this design is perfect for traditional amplitude shaping, allowing precise control over audio signals with minimal distortion. The VCA section excels in both subtle modulation and aggressive signal sculpting, making it a versatile choice for any patch.

Power consumption: 30mA at +12V and 47mA at -12V

Depth: 27mm

6 HP

Notes: The Octovert is a CV processor capable of scaling, inverting, and offsetting up to eight polyphonic signals. It can also be externally controlled via CV! Its most obvious applications include inverting envelopes, reversing the direction of CV, and scaling plus offsetting any CV source to precisely fine-tune the modulation sweet spot of the target module. With the added feature of external control, it takes things even further by modulating the modulation signal itself for even deeper modulation motion.

Size: 6HP - Depth: 40mm

Power: +12V 18mA / -12V 15mA

Notes: The core idea behind this module is all about control voltage. Hence all features are individually broken out to CV inputs, making the most use possible of the benefits of the digital wavetable oscillator. This means that the design is geared towards allowing hands-off control of all aspects and some concessions have been made to that effect.

Initial setup basically consists of connecting the power cable to the module and your bus. The cable has a slotted socket for correct orientation, but mind that the red stripe faces the white line on the edge of the PCB. The included screws are nylon in order to minimise rack-rash.

Tuning the module is possible by adjusting the small SMD trim potentiometer on the back. It adjusts the offset voltage that affects the centre point of the LFO oscillations. It should be close to its three o'clock position, but you can adjust it by turning the module on, reducing the output level to almost zero and turning the trim potentiometer until you find the point where the gate output led just barely turns off.

The LFO sync type is hard sync, meaning that it resets the current cycle to the beginning of the waveform. It does not control the duration of the cycles. This allows you to further shape the output to, say, three quarters of a sinewave by using external sync and adjusting the HZ knob so the duration of a cycle is just a little longer than the time between incoming sync pulses.

Colour coded nuts indicate the type of jack, with gold representing Gate/Trigger input, black is +-5v CV inputs and red jacks are outputs.

The CV inputs are scaled down to +-2.5v and added/subtracted with the knob setting, meaning that to sweep the full range of the parameter with CV, the knob should be in centre position. The inputs are clipped to the allowed range after mixing, so you can apply any eurorack voltage here.

The module's core processor is socketed, so using a simple PIC programmer and some basic Assembly knowledge you can modify its functionality to suit your needs.

The code is written by Electric Druid who supplies me the chips preprogrammed.

Fully voltage controllable Eurorack format, externally syncable, 16 waveform low frequency oscillator with built-in VCA and sample & hold.

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

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

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

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

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

Strings with a variable amount of inharmonicity.

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

Controls

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

Inputs and Outputs

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

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

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

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

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

Notes: The SetonixSynth SkyWave is an all-analogue voltage controlled oscillator capable of producing many different timbres and unique harmonic behaviours, thanks to an original step-based control scheme which allows the user to dial in completely different wave-shapes and levels for successive oscillator cycles.

This complex VCO uses an internal feedback loop with the clock output of the oscillator triggering a step sequencer which in turn cycles through settings at the frequency of the core oscillator, thus changing the shape and level of the waveform output on a per-cycle basis while also staying in tune and tracking pitch like a typical VCO.

Notes: Inspired by classic 70s analogue drum synths like the Syncussion and Syndrum, the Eurorack version of the Seven Sisters offers seven different sound modes, each with four CV-controllable parameters.

Supplier's notes:
Seven Sisters is a percussion synthesizer featuring seven voices that aims to capture the essence of late '70s instruments such as the Syncussion and Syndrum.

This module contains 7 presets, with one voice playable at a time. Each voice has four editable controls, including volume, and parameters such as decay, pitch, and filter, all of which can be controlled via CV. Each voice also includes multiple oscillators, noise generators, and filters, providing rich, complex tones beyond the capabilities of the original devices. This enables you to recreate classic sounds or craft more realistic snare, hi-hat, and cymbal effects. The result is a powerful percussion synthesizer that combines the essence of early drum synthesis with modern flexibility.

Notes: Punch MG is a unique module with VCA-DECAY & Mute GROUP designed for Eurorack systems.

This module has been specially crafted to generate dynamic percussive sounds while also offering the capability to manage multiple signals simultaneously through its innovative mute group feature.

Punch MG provides a versatile platform for crafting dynamic percussive sounds. With its mute group feature, it allows you to handle numerous signals concurrently.

The manual will guide you through the various features and functions of Punch MG, enabling you to explore its full potential.

Key Features:

Dynamic Sound Generation: Punch MG is engineered to generate dynamic percussive sounds with finesse, offering a range of creative possibilities.

Mute Group Interaction and Signal Patterning: Utilize the mute group feature to enable interactions between signals that share the same group.

This feature enables signal muting and amplitude limitation when multiple signals are triggered simultaneously. The amplitude and decay time of each signal are influenced by others in the same group. This characteristic can lead to captivating pattern variations when focusing on specific channels.

Expandable Capability: By linking two modules, you can expand the effect of the mute group to accommodate up to eight signals, fostering intricate interactions and captivating sonic landscapes.

AM Sound Creation: Connect audio rate signals to the level input to explore the creation of AM (Amplitude Modulation) sounds, further extending the sound design possibilities.

Envelope outs: Each envelope's polarity can be inverted using dedicated switches on the front panel, enabling you to achieve effects like side-chain compression and ducking. Moreover, the mute group circuit's influence extends to the envelope signal output, providing intriguing modulation capabilities that add a unique layer of creative expression to your sonic endeavours.

Notes: Welcome to the Rosci soundscape. Rosci is a digital VCO that generates random waveforms to create unique, rich, and full sounds. You are able to control how complex the sound is-add harmonics and have a completely unique shape generate using the generate button/trigger. BUT, it can also be tuned to output basic waveforms (sine, square, sawtooth) if you so desire.

Tunable parameters breakdown:

COMPLEXITY: Essentially a generation of unique timbre.
ROUNDNESS: Set the basic shape of your waveform. Go from from sharp to soft sound, similar to filtering.
HARMONICS: Add up to 6 harmonies to your sound. The choir's here.
FORMANTS: Accentuate certain overtones in your sound (like a voice singing "ooo", "ahh", "eee").
DETUNE: Add a classic 'detune' with a changing phase wave for extra wide sound.

How does it work?

It is a pipeline of algorithms, which generates and modifies a waveform starting from top to bottom. Rosci works on a principle of key points: the generate button generates key point location and amplitudes to be passed down the pipeline.

Tunable parameters:

Beginning with complexity, you set the number of key points (even numbers only to create a waveform). Lowest complexity sets two points, and highest complexity sets up to 20 points. The number of key points will vary with each waveform generated. From there, the roundness sets the type of interpolation of the key points, from square to sine. Adjusting the harmonics creates copies of the waveform and adds them to the original waveform at double, triple, ... up to 6x the base frequency. Formants maintains the frequency of the wave, but squishes it so there is 'empty space' in between (this is also called pulsar synthesis). Finally, detune copies the waveform and 'detunes it' by increasing the frequency ever so slightly. And there you have it: a unique Rosci soundscape :)

Notes: Rhythmi is a Eurorack drum sequencer that allows you to dial in your groove, and explore it by evolving the pattern and modulating the energy. It allows for rhythmic inspiration and creativity without the burden of step programming. The evolve parameter enables smooth transitions between related rhythms through the use of branches. New branches can be generated at the push of a button, loading up a whole new branch of related rhythms to explore. The Evolve parameter is the heart of Rhythmi, its inspiration, and defining feature. Allowing rhythms to shift, transform, and melt into one another.

The Clock Section provides internal or external clocking with division or multiplication. The Customize Section shapes individual drum elements through density and syncopation. The Global Section introduces macro-level control over the rhythm via the Energy, Evolve, Length and Swing parameters, dynamically shaping fills and variations. Rhythmi has a jumper cable connector on the back to pair up seamlessly with Beatsi, the drum voice it was designed alongside with.

Notes: Beatsi is Omni-Tone's love letter to modular drums! Inspired by classic modular drum synthesis which uses the fundamental building blocks, Beatsi's timbres were created using the same methods, only digitally. Beatsi is not a sample player or a physical modeller, and it's meant to be that way.

Beatsi's interface allows for control over individual piece Timbre, Pitch, Decay, and Level. The timbres are organized into 3 kits: an orange (acoustic) kit, a blue (low-fi) kit, and a green (alien) kit. Within these kits the timbres blend smoothly into one another allowing for seamless modulation. Beatsi has two CV modulation inputs which are assignable to any and all parameters with individual attenuversion. Beatsi may be small, but it packs a serious punch.

Notes: Designed for Make Noise's New Universal Synthesizer System but compatible with all Eurorack modules, the Jumbled is a 6-in/6-out VCA-based signal router, designed to manipulate and reimagine control voltage signals.

Supplier's Notes:
The Jumbler music synthesiser module is a six by six channel analogue signal combiner and distributor for the New Universal Synthesizer System or any Eurorack modular synthesiser. Jumble is one of the N.U.S.S. concepts where the routings of a patch could be re-configured, or jumbled, instantly via voltage control to produce variations on a theme.

Jumbler gives you powerful two-parameter access to the rearrangement of both origins and destinations for up to six modular signals. One to six inputs are routed to one to six outputs, in an order determined by the Rotate control, and combination determined by the Radiate control. Unlike a simple switch module, Jumbler's analogue VCA-based design is specially geared for smooth transitions and hybrid signals.

Jumbler is a great module for hybrid control voltage mashing, complex waveform mixing, on-the-fly effects re-routing, gate and clock re-combinations and more. Some folks have said it is like patching a stack of 6 RxMx circuits.

Notes: The Stereo I/O 1U is an all-in-one audio input/output module designed to bridge the gap between your Eurorack system and line-level devices. Whether you want to process external audio with your modules, monitor your patch with headphones, or connect your system to mixers or interfaces with line level - Stereo I/O 1U has got you covered.

Audio I/O allows you to effectively interface your Eurorack modular system to the balanced line-level world (+4 dBu). You can send and return to rack mount/desktop fx units, patch to external line-level instruments like synths and drum machines, interface to a DAW and much more.

The rear-mounted 3-pin CHAIN IN connector allows you to sum (in parallel) other audio sources to go from Eurorack level to the BAL LINE OUTPUTS. This could be from modules like the Mixup 3U, Xfade 1U, Stereo Mix 1U, and XY I/O 1U. You could also use this to connect with the 3-pin headers on the Palette and 7U cases audio i/o boards.

The rear-mounted 3-pin CHAIN OUT connector allows you to directly connect the level-shifted BAL LINE IN to the inputs of other compatible devices such as the Mixup 3U, Outs 3U, Stereo Mix 1U, XY IO 1U, and Headphones v2 1U. You could also connect the to the TRS jacks of the Palette and 7U cases audio i/o boards.

Dual Balanced ins and outs for the studio or the road. Interface your rack with the balanced line level world; send and return to pedals or desktop FX units; patch in and out of your DAW, external synths, drum machines and other line-level instruments.

A space-friendly, feature-rich, highly flexible solution for all your stereo line level input and output needs. Includes a dedicated headphone jack/volume and a clever cue bus for monitoring signals outside of the main output or to add a 2nd source to the main outputs.

Notes: Not just another clone or continuation of the 808-esque, acid-style kicks of the Mutant Bassdrum - the Mutant BD9 seeks to explore uncharted bassdrum territory by having an integrated sub-oscillator for maximal auditory obliteration.

Parametric bassdrum synthesis offers creative control of the core sound

The primary analogue VCO offers classic 909-esque sinusoidal bassdrums, but can also be switched to generate a square wave bassdrum

The PITCH of the VCO spans several octaves, from about 30Hz to 240Hz, and can be modulated with voltage control

A novel PITCH DECAY circuit allows you to adjust the duration and AMOUNT of the pitch-modulation envelope applied to the bassdrum, from short blips to exaggerated tom-like sweeps

The AMPLITUDE DECAY allows adjustment of the length of the bassdrum, from short punchy kicks to massive booms. This parameter is voltage-controlled with a snappy CV response time, allowing you to modulate the duration of your kicks per step.

The CLICK generator is responsible for the attack intensity of the BD9. A fair amount of circuitry goes into creating this subtle punch at the beginning of the kick. The level of this effect is adjustable up to a fairly dramatic extremity.

The overall timbre of the BD9 varies with the DRIVE control from warm, analogue bassdrums at low settings to speaker-shattering overdriven sounds at high settings. Output levels are modular-level signals, unlike many classic line-level percussive devices.

Still not heavy enough? Try the sub-oscillator.

A square wave sub-oscillator derived from the primary oscillator's pitch can be mixed in (manually and with voltage control) to the BD9. The effect can be subtle deepness or extreme timbre changes.

A jumper on the back of the module allows you to select between the sub-osc being a raw square wave or having some of the high frequency components removed with a lowpass filter.

At high OUTPUT DRIVE and SUB LVL combinations, the sub-oscillator can be modulated with CV to saturate the BD9 output in evolving ways.

The SUB OCT can be set to 0, -1 or -2 octaves down from the primary oscillator. A drop of 0 means that you can mix an equal-pitch square wave with a sinusoidal primary wave.

Designed for the contemporary modular synthesiser

Plenty of eurorack-compatible control voltage inputs with bipolar attenuverters allow synthesis of dynamic percussion

A practical analogue trigger circuit allows activation of the BD9 from many signal sources (anything with a positive-going edge lasting 2ms or longer). Most electronic drum pads can also directly trigger the Mutant BD9.

An accent input accepts analogue voltage control (0 to 5V will fully modulate the volume from low to high)

Notes: Solist is not your average performance mixer and mute combination - far from it. Designed in collaboration with Bries, Solist contains four channels of soft vactrol muting, controlled by tactile and pleasantly clicky mechanical switches. Solist will help make your performances shine - but most importantly, the red solo switches allow you to override the current state of the mute switches, allowing for creative transitions between solo and mute states during your performance.

While the audio circuit is fully analogue, it is also entirely isolated from the digital circuit that controls the mutes. Running on a fast and reliable Raspberry Pi RP2040, you get all the benefits of digital control without the downsides of digital audio processing. Best of all, the mechanical state of the switches determine the state of the module, so even if you power cycle, you will return to your previous state.

The analogue mixer section can be used simultaneously with the individual outputs of the Solist, so for those who already have a mixer solution, the buffered individual outputs will bypass the mixer entirely. You may of course also use both simultaneously for exciting parallel processing opportunities.

Solist brings a whole new aspect of muting and soloing to your Eurorack performances, and with soft opening and closing vactrols, you'll never have to worry about clicks, truncated transients or actuation noise.

Notes: Chris Huggett, chief designer at EDP came up with a novel little circuit for the filter envelope of the Wasp, based around half a CD4013, half a CD4066 and half a LM3900. It was an A/R generator with looping option which would proceed through its whole cycle from only a trigger input. He further developed the circuit for the filter envelope in the Gnat to use just one knob to provide a range of attack envelopes when anti-clockwise (from 12 o'clock), and a range of release envelopes when clockwise (from 12 o'clock). 12 o'clock gives a very short symmetrical blip. As you can build two of these with a CD4013, CD4066 and LM3900, Frequency Central have provided both a two knob version and a one knob version, each has its own place.

Both envelope outputs are 0V to 5V.

Notes: Pretzel Logic is a 4 bit to 16 step addressable analogue sequencer which outputs gates. Each of it's 16 steps can be addressed in any order for ultimate creative flexibility. It pairs nicely with Polygraf, High Towers and Akropoli; together they make a powerful combination.

It features 4 address inputs, 1, 2, 4 and 8, each of which has an associated input socket as well as a 3 position state switch which allows each address input to be held high, respond to input signals, or held low. Each input has two status LEDs. The red LED displays the signal present at the input socket, while the green LED displays the status of the address input. The combination of signals present at the input sockets, together with the positions of the state switches allows Pretzel Logic to have 16 different output states, numbered from 0 through to 15. The output state of Pretzel Logic can be ascertained by observing which of the 4 address inputs are high. So, for example:

- If no green status LEDs are on, Pretzel Logic is in output state 0

- If green status LED 4 is on, Pretzel Logic is in output state 4

- If green status LEDs 1, 2 and 4 are on, Pretzel Logic is in output state 7

- If green status LEDs 2 and 8 are on, Pretzel Logic is in output state 10

The input sockets may be addressed by various external modules, for example:

- FC Pocket Calculator, FC High Towers, or similar clock dividers with multiple outputs from other manufacturers.

- FC Polygraf or similar grid editors from other manufacturers.

- FC Little Melody, Akropoli or similar.

As Polygraf is capable of storing many user patterns which themselves are selectable by CV, multiple chained patterns are possible. Furthermore, we accept that users will discover their own unique combinations of FC and third party modules to address Pretzel Logic, always bearing in mind that at any time the status of any of the 4 input sockets may be overridden by the 4 state switches. Pretzel Logic may be latched manually via the Latch toggle switch, or externally via the Latch input. When Pretzel Logic is latched, the last output state to go high is held until Pretzel Logic is unlatched.

Notes: Typically creative stuff from Frap Tools, the Bagai offers analogue sample and hold, but crushing and down sampling, but its combination of six interlinked, CV-controlled sections is capable of much more.

Supplier's Notes:
bagai / ba'ga?i / s.m. [modenese dialect, from a late Latin bagagium 'baggage', formed after the late Latin baga, deriving presumably from the Anglo-Saxon bag (see ancient French bague, Provencal bagua, 'bundle'), whose root may be traced down to the Indo-European *pac, 'to tie,' from which also 'package,' 'pact'] - 'thing,' 'thingamabob.' A term used when the actual name of a thing or a person does not come to mind.

A module that is at the same time a clock burst, S&H, audio bitcrush, or fluctuating random voltage generator is indeed a bit elusive to describe in a single word. Even if one tries, some aspects will always be missing.

Why bother, then? Let's just call it "that thingamabob," or better, "that bagai."


Bagai is an analogue sample and hold, bitcrusher, and downsampler for Eurorack systems, also capable of generating clock bursts, fluctuating random voltages, and coloured noise.

It consists of six highly intertwined sections:

A clock with straight and random outputs (yellow)

An analogue noise generator with variable colour (grey)

A bipolar fluctuating random voltage generator (white) with variable rate

A sample and hold the circuit (orange) with selectable time scale, slow for modulation, or fast for audio sampling up to 48 kHz.

An 8-bit quantized version of the orange S&H circuit with variable bit depth (red)

A clock burst section (green).

By default, it outputs bipolar random voltages and triggers. The voltages are fluctuating, stepped, and quantized with selectable bit depth. The clocks are straight, randomized, or "burst."

Once you start patching, you can use it as a S&H, audio downsampler, and bitcrusher, with a sample rate of 48 kHz.

All its major parameters are voltage controllable.

It belongs to the same family as Sapel, with the following differences.

Sample and Hold with an 8-Bit Quantiser

Bagai features two stepped S&H circuits with open input (semi-normalled by default to an analogue noise source).

The quantized one has a LSB selector that defines its bit depth, from 1 to 8 bits.
Random Triggers & Clock Bursts

Besides the well-known "main," "more than," and "less than" modes, Bagai also features a clock burst circuit that creates super fast and unpredictable streams of gates that you can combine with the main clock or to any other trigger you want.

Voltage-Controllable Bitcrusher

When used with audio signals, the 8-bit quantized S&H becomes a warm bitcrusher effect with voltage-controllable bit depth!

Dynamic Downsampler

Bagai's internal clock can switch to an audio rate mode going up to 34 kHz. Patching audio signals into the S&H input will transform Bagai into an analog audio downsampler.

Open Signal Path

Lots of semi-normalled connections allow you to use Bagai in infinite ways: cross-patching has never been this fun.

Start and Stop Controls

You can control both the main clock and the clock bursts via external gates. The main clock also features a button to manually hold it.

Analogue Noise

At Bagai's core is a thermal noise generator that feeds the S&H circuit, creating random voltage streams. The noise output features a knob that changes its colour, emphasizing the high or low frequencies.

Notes: Really nice melody sequencer module from Flame. Create patterns and then modify them using features like note repeats, transposing options or even the built-in distance sensor.

Supplier's Notes:
"TON" is a 12HP wide Eurorack live sequencer module for creating two note sequences. There are two 1V/octave outputs with GATE/NOTE/VELOCITY. Notes can also be sent via MIDI. Both note tracks are independent of each other and can be used in different octave spreads. In addition to the analog connection, the module has full MIDI functionality. It can be synchronized via analogue clock or via MIDI.

The sequencer is designed as a looper. It plays a pattern of up to four bars in a loop. The notes can be played (or deleted) quantized with two buttons. One button is used for note repeats, another for setting individual events. The pitch is determined by either the potentiometer or the built-in distance sensor. The sensor works in a range of about 1 to 40 cm and is independent of extraneous light. Even bright sunlight does not affect it.

A 1-octave mini-keyboard allows transposing on the fly and setting a scale. Since the module has two CV inputs, it can also be used as a two-channel quantizer or arpeggiator. All settings of the current pattern are simply saved together in a patch. There are 5 banks with 7 seats each (per mini-keyboard) available. This allows up to 35 patterns to be managed. The patches can also be selected via CV or MIDI program change and can be saved and reloaded on the fly.

The pattern can be manipulated during and after the import with eg: gate length, velocity, random, last step, hold, mute, glide, scale and transposition. Both tracks can have different settings. With TRACK-Link, however, parameters can also be applied to both tracks at the same time. This is helpful, for example, with transpositions or duophonic playing.

Notes: The brilliant Perkons drum machine comes to Eurorack. A single hybrid drum voice with digital sound engine and analogue filter/overdrive, the Perkons Voice is flexible and supremely powerful.

Supplier's Notes:

Like on the drum machine, the module has hybrid architecture, featuring a digital sound engine followed by an analogue multimode filter and overdrive. Users can select among 13 sound generation algorithms and save up to 99 presets that can be recalled easily. Tune and Patch CV inputs are configurable for various CV settings and are tuned to 1V/oct. Module also features a 4-voice poly overlap mode and samples on the "Rompler" engine can be easily replaced.

Notes: Module A-135-5 is a combination of a voltage controlled polyphonic mixer and a polyphonic suboctave generator.

Module A-135-5 is a combination of a voltage controlled polyphonic mixer and a polyphonic suboctave generator. It is made of 12 voltage-controlled amplifiers (VCAs) which are arranged in form of a 4x3 matrix. Herewith up to three four-voice polyphonic signals (e.g. the outputs of three polyphonic VCOs A-111-4) can be mixed. The level of each of the three polyphonic channels (A, B, C) with four voices each can be controlled manually or by means of an external control voltage with associated attenuators.

In addition, the module features four frequency dividers which derive the suboctaves from the four input signals of channel A. The suboctave signals are wired to the switching contacts of the sockets of channel B. As long as the sockets of channel B are not patched the suboctave signals of channel A are used as inputs for channel B. The suboctaves are symmetrical rectangle waves with half the frequency of the corresponding signal A. For example, two polyphonic VCOs A-111-4) can be used and patched to the channels A and C. Channel B then provides the suboctaves of channel A.

The switching contacts of the 12 input sockets and the four outputs are internally connected to pin headers. That way the module can be internally pre-patched to other polyphonic modules (e.g. the four inputs A to an A-111-4, the four inputs C to another A-111-4 and the outputs to the polyphonic filter A-105-4). As the switching contacts of the sockets are used for the internal pre-patching the internal patch can be overridden by using the sockets at the front panel.

Technical notes:

If required two or more modules can be cascaded when more than three polyphonic channels are required.

The max. overall amplification is less than 1 to avoid clipping (can be altered to amplification 1 by replacing resistors, but then clipping may occur)

The max. input levels without distortion are about 16Vpp (or -8V ... +8V for the processing of control signals)

The voltage range for each of the CV inputs is about 0...+5V (with corresponding attenuator control fully CW), higher control voltages (e.g. 0...+10V) can be adjusted by means of the attenuator control

The suboctave levels are about 5Vpp

The module should be used only with DC coupled VCO outputs (e.g. A-111-4, A-111-3). With AC coupled VCO outputs (e.g. A-110-1, A-110-2) a DC offset will occur at the outputs when the suboctave option is installed.

The document A135_5_INTERNAL explains the positions and functions of the internal pin headers and describes the cascading of two A-135-5

Notes: Silver version of Cosmotronic's Messor module, offering stereo compression and transient shaping in just 8 hp. Ideal for mix buss compression, whether full stereo mix or drum/synth submixes.

Supplier's Notes:
Messor is an analogue stereo compressor with lots of tricks up its sleeve, in only 8HP.

From squashing drums, sidechaining kicks and sculpting transients, to glueing a mix together, it's a very versatile dynamics manager.

At its core it's a VCA based feed-forward compressor with a low noise signal path. The magic is in the internal sidechain that shapes the gain reduction envelope. This starts with a a switchable high-pass / low-pass filter, before going into a precision envelope follower, controlled by familiar parameters: the attack, release, threshold, ratio and makeup gain.

The ratio can go past limiting and into over-compression, which can completely reshape transients, a great tool for sound design.

Being modular, of course there are CV inputs for Attack, Release and the side-chain Filter cutoff. The Gain CV controls the makeup gain, but also doubles as a Stereo VCA with the Gain knob turned fully CCW.

The gain reduction envelope is also available as an output, for turning filters or other VCA's into compressors for example, or as a standalone envelope follower.

There's a bypass switch, and a Warm mode, that can bring in a bit of additional saturation and compression in the form of analog tube simulation circuitry.

Lastly there's the possibility to insert an external sidechain, for that classic kick sidechain compression.

Notes: Great value dual function generator here. Create envelopes, slew signals, shape modulation and generate LFOs. All with built-in VCAs for each channel. A proper multi-function utility module.

Supplier's Notes:
Delta-V is a fully analogue dual-channel function generator, featuring a dedicated VCA and LFO cycle switch for each channel. It packs a great deal of functionality in only 10HP, and will surely find use in almost every patch.

Generate envelopes, slew gates and signals, or run LFOs with precise control over attack and decay times. Using the SHAPE knob, Delta-v can create a wide range of envelopes, from very snappy exponential curves for percussion to logarithmic thumps for bass lines.

If VCA's input is unpatched, the module outputs a regular voltage envelope. When an audio signal is patched into the VCA input, the output signal becomes the audio signal amplified by the envelope.

Sending other envelopes or an LFO to VCA input lets you modulate those modulators, quickly creating complex control voltages that go beyond the usual attack-decay envelope.

Combine this with the SUM output, which sums the two channels, and the attenuverters, which can quickly attenuate or invert the signal, and you have a whole array of signal processing capabilities.

The TRIGGER input fires a Attack-Decay envelope, while the SLEW input will affect the rate of change of the signal.

The trigger for channel 1 and 2 can be linked together, so you can fire two envelopes with one patch cable.

Each channel has an End of Cycle output, (EOC) this outputs a short trigger at the end of each envelope cycle.

The output voltage ranges from -10 to +10 volts, set with handy output attenuverters.

The CYCLE switch starts looping the envelope, creating LFO's that go up to audio rate, and that can also be used as an interesting sound source.

There are many ways to utilise Delta-V.

Notes: Part of TipTop's exceptional series of Eurorack-format Buchla modules, the 264t provides four sample-and-hold circuits, plus a logic circuit designed to control polyphonic patches. Deceptively simple but surprisingly creative, like most Buchla modules.

Supplier's Notes:
Four independent sample-and-hold circuits, plus a specialized logic circuit for expediently implementing polyphonic patches.

Sample-and-hold's are essentially one-cell analog memories. They are useful for "remembering" the instantaneous value of a control voltage (a detected envelope, for example), for generating equally spaced steps from a constant slope input (as from a 281t envelope generator), and for converting any continuously changing voltage (a random voltage, for instance) into a series of discrete values.

The 264's sample-and-hold circuits have two operating modes: sample and track. In the sample mode, the value of the input is sampled and applied to the output whenever a pulse is received. The output remains at this value until the next pulse arrives. The track mode diers in that an input is applied to the output for the duration of the pulse. The output tracks the input until the end of the pulse and remains at a constant value until the next pulse.

To use the 264t as four independent channels set the separate/common switch to separate. A single CV can be set to all four channels by setting the operate/common to common and plug CV in the the back jack on the with right side.

The Model 264t includes a polyphonic adaptor, which performs the logic necessary to implement four-voice polyphony. Facilities are incorporated for fine tuning and f.m. modulating the oscillators; light emitters display the adaptor's operation.

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: ***B-STOCK: Box opened, product in perfect working order***


Tiptop's reissues of iconic Buchla modules continue with the 285 frequency shifter. Edgy, twangy harmonic modulation with ring mod options and stereo operation via sum and difference outputs.

Supplier's Notes:
The 285t combines two sets of functions: the top section features a frequency shifter, while the lower section includes both balanced modulation and classic ring modulation, all with voltage control. The frequency shifter can shift incoming audio using either its internal oscillator or external audio. Both SUM and Difference outputs are available simultaneously for analogue stereo widening effects and more.

As Tiptop Audio continues its aural odyssey of preserving and transforming the hallmark engineering prowess of Don Buchla's namesake synthesizer modules, the 285t brings a constellation of blistering sonic-contouring tools to your Eurorack array. Like its predecessor, the Tiptop Audio Buchla 285t is a menagerie of modulation madness, offering variable degrees of ring, frequency, and amplitude styles of modulation. Plus, its dyad of modulation sub-modules operates independently, with dedicated audio and CV I/O for each, functionally giving you the sum of performance possibilities you'd get with two modules, all in one instrument. Suffice it to say: Sweetwater's synthesists commend Tiptop Audio on capturing the electric magic of Don Buchla's imaginative engineering while transposing it for the world of Eurorack to experience. For a constellation of timbral sculpting and summitting heretofore unknown peaks of daring synthesis exploration, the Tiptop Audio Buchla 285t Frequency Shifter module is your key. Discover what awaits at the fringes of Eurorack possibility!

Notes: What does this do?

This is an analogue filter with a separate 3 channel mono mixer, and VCA combo. There is also an internal envelope generator with Decay. All this product needs is a VCO and a trigger signal to complete a mini voice.

The outputs on the filter are meant to be manually patched into one of the VCA audio inputs on the module to complete the mini voice. You can mix and match to create custom filter types.

The Feedback on the product 'Rez', is what makes this sound like an MS20 filter. There are diodes, used as a limiter, and also to wave shape when in self oscillation mode.

Features:

-2 audio inputs with 2 level control knobs.

-Bi-polar FM for the filter.

-Mod input with level knob for the filter.

-FCV Filter CV direct input for the filter.

All CV inputs for the Filter are 1V per octave, Exponential.

Notes: Oscar DSF is a complex, stereo Voltage Controlled Oscillator, based on the mathematics of Discrete Summation Formulae.

The Discrete Summation Formula used in Oscar DSF produces sounds rich in harmonics (or 'partials') in a similar way to FM.

The mathematics of DSFs is more complex than FM, but the way that you, the user, get the sounds you want is usually simpler. The basic sound is controlled by just two, intuitive knobs (with CVs, of course).

Oscar DSF can sound like a traditional oscillator, and it can make the usual clangs and tings associated with FM oscillators. It can handle fat bass sounds, or evolving ambient drones.

Oscar DSF has two complete DSF based, complex oscillators, controlled by the same basic pitch CV, but with a pitch offset control which can detune one oscillator up to i1 octave.

The output of the each oscillator passes through another complex FM stage, which acts like a wave folder. Technically, it's actually an FM operator with the carrier frequency set to zero. It sounds great, whatever you call it.

The final piece of the signal chain is a simple VCA, allowing Oscar DSF to be used as a stand alone synth voice with the addition of an envelope generator, or some other source of modulation.

Notes: Alpha Duo is a stereo precision VCA with ring modulation, overdrive and distortion.

Alpha Duo's VCAs have three modes:

1) Two quadrant, for classic VCA behaviour
2) Four quadrant, where the VCA responds to both positive and negative Gain CVs. This creates a classic ring modulator.
3) In four quadrant separate (4S) mode, each of the two VCA channels is controlled by separate gain CVs, turning Alpha Duo into two independent VCA/ring modulators.

Alpha Duo also features three drive modes.

1) In Drive Mode zero the overdrive circuit is not active, giving a clean signal.
2) Drive Mode One is a tube style soft overdrive. Like a tube, the positive and negative parts of the waveform are distorted differently, producing a pleasing, warm fuzz.
3) Drive Mode Two is a harder clip - more like a transistor amplifier - for a harder edged distortion.

Alpha Duo's signal path is DC coupled, so it's great for processing CVs as well as audio.

Dimensions is a true stereo chorus effect for the Eurorack modular system featuring two algorithms. The first is a direct port of our Fluid chorus plug-in, and the second is taken from the unit's namesake. With automatic routing based upon what you plug in the I/O, Dimensions can do mono->mono, mono->stereo, and true stereo chorus duties.

Dimensions' Mode A operation is a ludicrously thick chorus. Most chorus effects have either a single delay line or a pair. Dimensions has six of them, each with its own modulation scheme. The Mode B operation changes the routing to match the vintage rack unit, but keeps the controls available. This results in a subtly different, but equally thick and appealing, effect.

Notes: THE SBG-PRO supports mono, stereo, balanced, and unbalanced input and output via 6.35mm jacks with level matching controls with clipping indication. The module features both direct and voltagecontrolled equal power crossfading between wet and dry sources.

Additionally, an expression input, along with the included 'floating ring' cable and conditioned output, ensures safe, voltage-limited CV control of external devices from your modular system.

The module extends its sibling, the original S.B.G, by adding full size stereo balanced jack connections and voltage control focusing more on connectivity with not just pedals but also pro audio equipment including rack effects, 500 Series modules and mixing consoles.

Notes: Keanu is a partnership with Tim Held and Podular Modcast. At its core, Keanu is a standard 4x4 matrix mixer and VCAs on each output and switch to choose between unipolar or bipolar controls. After Later have also added modulation sources normalled into each channel. So you get some great modulation variety, but can also mix in your external sources.

Channels 1 & 2 CVs are clockable looping function generators with controls for rise/fall lengths, and equipped with end of rise/fall trigger outputs.

Channels 3 & 4 are each a "meandering" voltage source, created by 3 LFOs that are all at different frequencies. There are 3 CV inputs (total) to control their individual rates. You can also add slew to each channel individually to change the oscillators from square to triangle, and this slew also applies to external voltages sent into their channel.

A fresh twist on a simple 303-style acid synth, featuring a triangle/sawtooth/square wave VCO, multi-mode resonant filter, simple AD envelope and a VCA which can be overdriven. Excellent value.

Supplier's Notes:
ADDAC started this module with the idea of developing a complex drum source however, somewhere along the process, it was clear how much better it performed as a synth voice and this lucky accident was embraced.

It features a VCO with a [FREQUENCY] and [FINE TUNE] knob plus a dedicated CV Input and Attenuator knob (tunable over 4 octaves).

The VCO waveform output is achieved by selecting either a Triangle or Saw through a switch. the selected waveform can then be mixed/balanced against the square wave. The resulting mix is then sent to the Filter.

The Filter features a [CUTOFF] and [RESO] resonance knob plus a Cutoff CV Input and Attenuverter knob.

A 3 position switch is used to select the filter type: Highpass, Bandpass or Lowpass.

The resulting output is then sent to the VCA.

The VCA features an Input with [INPUT GAIN] knob which at maximum can amplify the incoming signal by a factor of 2.

This is a very important control, it accepts any signal Trigger, Gate or CV. Whatever input is plugged in the signal is then fed through an AD with a very short attack and controllable decay through the [VCA DECAY] knob plus the CV Input and Attenuverter knob. The resulting slewed signal is then used to control the VCA gain.

This signal is also sent to the CV OUTPUT as well as the LED monitor.

The Accent input adds to the Input signal creating a different amplitude output.


The CV OUTPUT is normalled to the Frequency and Cutoff inputs.

The [INPUT GAIN] knob

Usually Attack/Decay envelopes have a maximum voltage of +5v, no matter if the input gate is +5v or above the AD will clip at +5v. In this case, this clipping method was not used, and instead ADDAC allowed the incoming voltage to determine the maximum AD voltage, meaning that if a +5v gate is present then the AD maximum voltage will be +5v but if a gate of +10v is sent then the AD maximum voltage will be +10v.
This also means that with higher input voltages the decay, although falling at the same speed, will be longer than with lower voltages as it has a longer range to go back to 0v.

As previously mentioned, The [INPUT GAIN] knob can amplify the incoming input by a factor of 2, allowing to use a standard +5v gate or envelope and being able to make the resultant AD go up to +10v.

The AD signal is responsible for opening the VCA. Up to +5v the VCA will open to unity gain above this value the VCA will start to amplify and eventually saturate and distort. This saturation will add harmonics to the signal which will change its gentle timbrical nature to a more unique and peculiar timbre that will make the module shine in Acid contexts.

Adding high levels of Resonance or even filter self oscillation in combination with high VCA saturation will create even more harmonics that ADDAC highly encourage the user to explore.
