Notes: Part of Xaoc's range of modular mixing tools, the Bohumin 1966 is a commander module for Ostrawa stereo mixer modules, adding a second stereo aux bus, voltage control and manual attenuators with clickless mutes

Supplier's notes:
Bohumin [bo'xumin] is an expander for Xoac Deives' Ostrawa full stereo mixer module. By connecting to Bohumin, Ostrawa gains a second full stereo AUX bus with voltage control over the amount of the effect on each channel. Bohumin features manual attenuators for stereo returns of both AUX A and AUX B, as well as four gate inputs for automated clickless muting of each stereo input channel. Please note that Bohumin is not compatible with Ostrawa's sister module Praga. Similarly, Praga's expander Hrad cannot be connected to Ostrawa. However it is possible to chain any combination of Ostrawas and Pragas, and each of them may have its corresponding expander attached.

Notes: Another update for WMD's clever dual VCA, this time a little bigger to give more control. Digital control of CV and attenuation gives lots of creative options. Third time's a charm.

Supplier's Notes:
WMD have done several designs of this circuit over the years, the first one had no knobs, the second was too small, the MKIII is finally how this circuit should be packaged. This module does some really cool stuff and is super useful in any system.

The Digital VCA lets signal through like a normal VCA, but the CV and attenuation level is controlled digitally. This lets us do things like wait until there is a zero crossing to change the amplitude, resulting in clickless amplitude changes.

The Trigger mode causes the VCA to only update when a trigger is received. The addition of a noise circuit for each side let us do a very quick and easy sample and hold that never droops. With no input, 5V is normaled to the attenuator, so you get a 0-5V sample and hold. In Bipolar mode, you can get -5 to +5V.

Both sides have bipolar VCA mode (polarizer), which lets them invert the signal when negative CV comes in. Also known as ring modulation. With the zero crossing detector, this can produce some super wild wave shapes.

Notes: The Ultimate Eurorack Utility Module (and a whole lot more!)

The DATA is a digital platform for testing, measurement, and signal generation in Eurorack modular synthesis systems. It is a modular tool kit, with functions applicable to any system and style.

Use the DATA's scope to view the interactions between your control voltages and audio signals, allowing you to master your modules by understanding their voltage ranges, control shapes, and parameter responses. Use the DATA's dual waveform generator to dial in a precisely scaled LFO for CV control, or use the waveform's frequency "note mode" to effortlessly make dyads (two note chords). Use the DATA's clock program as a master clock or to divide or multiply an incoming clock signal, sending four different clock outs to gate modules directly or as control to sequencers.

The possibilities of the DATA are basically unlimited; with the included microSD you can update the DATA's firmware and we can continue to refine and create new programs.

Notes: A compact Voltage Controlled Oscillator designed for generating SINE waves, Variable wave-SHAPEs, SUB-Octaves, Oscillator SYNC and Linear FM in the analog domain.

The Sub-Timbral Oscillator is the more subtle and melodic friend to the DPO's complex harmonic lattice.

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

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

Notes: Erica Pico INPUT module is just what you need to interface your modular system with external synths or even your mp3 player or mobile phone.

It boosts external signal to modular synth signal level.

With the Pico Input, line signals from, for example, a synthesizer, drum-computer, audio interface or smartphone can be raised to modular level. The module delivers up to 40 dB of gain. Thanks to its two channels, users can comfortably process mono as well as stereo material.

The Pico Input comes equipped with two signal paths. Each signal path features an audio input, a volume potentiometer and an output. Up to 40 dB of amplification are available. Using jumpers on the circuit board, it is possible to dampen the maximum gain to 20 dB. The module's first input is a stereo jack, meaning the user can connect a smartphone or tablet without any adapter cables. In this case, incoming signals are distributed internally to both channels.

Notes: Compact take on the Bitbox sampler, also offered as the larger Mk2 version. Touchscreen-based design allowing up to eight stereo samples, recording directly or loaded from SD card.

Supplier notes:
Bitbox micro provides Eurorack sampling for smaller racks and smaller budgets. In only 18 HP of rack space you can get a touch screen based sampler with support for 8 stereo sample pads. Now you can record samples directly into the module or load them from the microSD card. Trigger your samples via CV or MIDI, then apply effects and mix the outputs.

Notes: This is a buffered/active mult with LED indicator. You get two channels of 1 to 3 multiples within a 2HP module. The output of channel 1 is normalled to channel 2 so it can also be treated as a 1 to 6 multiple as well.

Active vs Passive mults:

With a passive mult you are effectively just plugging multiple things into the same jacks. This will often cause some voltage drop in each of the signals. With an active (or buffered) mult you will not get any voltage drop from the original signal.

Comes with a black and gold panel, power cable and one year warranty.

Usage note:

The red stripe of the power ribbon cable goes towards the top of this module.

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

Technical Specifications:

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

Notes: Module A-183-9 is a simple power supply for up to four devices which can be powered via USB (e.g. keyboards, smartphones). An LED shows is the +5V are present.

The module has no USB function but provides only the +5V supply for USB devices.

A control LED shows if the +5V are present.

Note: The module requires an A-100 case with built in power supply A-100PSU3. Only this A-100 supply has the required +5V available. We do not recommend the usage of an older A-100 case with A-100PSU2 as this would require the +5V adapter A-100AD5 and the max. current would be limited to 100mA.

Notes: The Multi-Delay Processor is a creatively usable echo effect with eight taps. The module's sound may remind you of classic bucket-brigade devices. - It even generates distinctive pitch effects when altering the delay time. An input mixer gives audio material a crisp, analogue character. Thanks to feedback channels with pitch shifter and reverb processor, shimmering echoes and other atmospheric effects can be achieved. A total of nine envelope followers and 14 audio outputs invite you to do extensive feedback patches and other edgy experiments.

The Multi-Delay Processor isn't just a high-quality echo effect but was designed to be a fundamental ingredient of patches. Its core is a bank of eight digital delays, which are wired in series. Together, the circuits form a multi-tap echo. The volume of each signal repetition as well as the raw material can be adjusted via faders. Furthermore, there are individual audio and envelope follower CV outputs for the dry signal and all taps. An analogue clock is used to control the echo circuits. The delay time can be set manually via a potentiometer plus there are two CV inputs with bipolar attenuators. Altering the delay time parameter during operation leads to pitch effects. At this point at latest, you'll realize the superiority of the serial memory design used by Mark Verbos over average effect chips. Despite its digital core, the Multi-Delay Processor offers charming sound reminiscent of a classic bucket-brigade device. - Only cleaner and more transparent.

A three-channel mixer with dedicated level potentiometers adds analogue character to signals before they are fed to the delay circuits. Without patch cables plucked into the second and / or third input, you can use these channels as feedback paths with additional effects. In detail, a pitch shifter calibrated to +1 octave (channel 2) and a reverb (channel 3) are available. - A perfect setup for creating shimmering echoes and other atmospheric effects. High feedback values make the module self-oscillate. In contrast to the multi-tap delay, which consists of individual components, an FV-1 chip is used for pitch shifting and reverberation. This processor is well-known, as it is the main component of multi-effects modules like the Erica Black Hole DSP and numerous guitar pedals. Here, the FV-1 is "just" a creative addition to the main effect.

In addition to the manual mix output, which emits the mixture of raw and effect material dialled in via the faders, there are four other audio outs. Two of these connectors provide signals derived from summing up all even respectively odd taps. The other sockets emit preset mixes with increasing or decreasing level. - Very cool for quickly creating special effects.

Notes: Black Stereo Mixer is just what you need, if your setup has several nowadays gaining popularity modules with stereo inputs or outputs, like Black Hole DSP, Erica Fusion Delay, MI Clouds or some other. In order to save rack space, we designed compact mixer with lot of cool, performance oriented features.

In order to save rack space, we designed a compact mixer with a lot of cool, performance oriented features.

Check out also the Black Pre-fade Listen Expander that is a satellite module to Erica Synths Black Stereo Mixer!

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.

Notes: Module A-134-2 contains two identical voltage controlled crossfader units.

Each unit has two voltage controlled amplifiers (VCAs) with opposite control behaviour available. The outputs of the two VCAs are mixed together to obtain a common output. The behaviour of the control voltage inputs can be chosen with an internal jumper:

Symmetrical mode: If the corresponding jumper is not set both VCAs of the crossfader have the same 50% amplification with zero CV. If the applied CV becomes positive the amplification of VCA1 decreases and those of VCA2 increases in the same way. A negative CV has the opposite result. The CV voltage range to obtain the maximum/minimum positions of the crossfader is about -2.5....+2.5V. This mode is useful for bidirectional (i.e. positive and negative) control voltages, for example LFO or joy stick (adjusted to 0V CV in centre position).

Asymmetrical mode: If the corresponding jumper is set VCA2 is fully closed and VCA1 has full 100% amplification with zero CV. If the applied CV becomes positive the amplification of VCA1 decreases and those of VCA2 increases in the same way. The CV voltage range to obtain the maximum/minimum positions of the crossfader is about 0...+5V. A negative CV has no function in this mode. This mode is useful for unidirectional (i.e. only positive) control voltages, for example ADSR, ribbon controller or Theremin control voltage.

The CV input of the upper unit (CV1) is normalled to the CV input of the lower unit (CV2). I.e. if no plug is inserted to CV2 the CV input of the upper unit (CV1) also controls the lower unit.

The second signal input of the upper unit (In1B) is normalled to the first signal input of the lower unit (In2A). I.e. if no plug is inserted into In2A the signal In1B is used as the first signal input of the second unit.

As the inputs and outputs are DC coupled the module can be used for both audio and control voltage signal processing.

Notes: Scales is an 8hp dual-channel note quantizer and step sequencer. Fundamentally, it takes an input voltage, quantizes it to notes in a user-defined scale, and sends that quantized voltage to an output, where you can use it as a melodic pitch source for oscillators or any other module that expects to see discreet note values at its input.

Scales goes far beyond the fundamental, allowing you unprecedented control of the pitches and intervals hiding inside your control voltages; turn LFO's into arpeggiators; random voltages into harmonic counterpoint; and unquantized external CV sequencers into chromatically tuned note sequencers.

Quantization can be locked to an incoming trigger. There are a number of trigger output options as well, ranging from no triggering (good for pitch shifting drones); through triggers that sync with either of the two outputs (or both); to a trigger or gate transmitted in sync with one sent to the module's TRIG input.

Shift:

Scales features two independent outputs, enabling you to create shifted harmonic intervals within your chosen scale using only a single pitch input. Using the SHIFT input you can modulate changes on OUT A and/or OUT B.

You can also use the shift input to switch between scales or to change the root of any existing scale pattern or split Scales into two quantizers - each conforming to a common scale, but fed entirely different voltage sources.

Sequence:

Scales also features a 128-step SH-101 style step sequencer (complete with storage for up to 35 fully programmable patterns) - allowing you to feed OUT B with sequenced notes and rhythm patterns, while OUT A continues to function as a standard pitch quantizer for external voltages. You can even sync the sequencer to quantizer events on OUT A.

Notes: The Control Voltage Processor from Verbos Electronics GmbH is a suite of control voltage processing possibilities divided into 3 sections in a slim 18HP package. The lower 2 sections are DC coupled mixers that allow mixing, inverting, offsetting, scaling, multiplying, dividing, crossfading or a combination of these functions. The top section is a voltage controlled slewing processor with independent control of Positive and Negative slew rate, with some unique tricks. The Positive and Negative slew, or Rise and Fall rates if you like, have reversing attenuators. The slopes can be blended from linear to RC curves (starting all slides fast and ending slow, like a proper "East Coast" Portamento) without a change in speed. It can be triggered like an AD envelope and has a Gate out that goes high when the CV out is below 100mV. Of course it can loop by patching the Gate out to the Trigger in. The Bounce control adds a unique flare of overshoot to CV changes, a bit like the effect of stopping a tape reel from turning and then letting it go. The combination of multiple voltage processors offers the user the functions of analogue computer.

Notes: X-PAN is a compact and powerful 5 channel Voltage Controlled Stereo Mixer with Low Noise and High Headroom allowing for creation of complex panoramic audio imagery in just 10hp.

X-PAN is highly responsive to control signals allowing for exploration of the fluctuating stereo sidebands possible with Audio Rate Crossfading and Panning. X-PAN is Direct coupled for use as a CV Processing and Routing toolbox.

X-PAN consists of two full featured Channels and one simpler Channel. The top two Channels each have voltage controlled cross-fading and panning while the third Channel is a stereo aux input with stereo VCA. All three Channels are combined together at the stereo SUM outputs.

Notes: Pico Drum2 is compact yet versatile percussion synthesizer in a 3 HP eurorack module. It features 8 drum synthesis algorithms created to deliver distinct sounds to your modular system. Each algorithm offers a lot of flexibility therefore a big sounding bass drum and a squelchy snare can be dialled in within the same algorithm. It also tracks 1V/Oct and all parameters can be mapped to the CV1 input.

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: The CP909 is the TR-909 clap sound analog generator in Eurorack format. This is yet another low-cost analog drum generator from a legendary drum machine in your modular synthesizer, expanding your Tiptop Audio modular drum machine even further.

The CP909 is an exact reproduction of the original analog circuit and, with the addition of just one extra knob, "trashing" the frequency of the internal noise generator, we have added greatly to the spectrum of sounds that can be generated - all that without compromising the signature sound of the TR-909 clap.

The CP909 clap effect is made by a special triple-saw envelope generator that controls the gain of a VCA. The sound source feeding into the VCA is made by a quasi-random logic based noise generator; some might call it "digital noise" though this term might be misleading in today's world of microcontrollers and sound samples. What really makes the noise generator is a ring of logic gates, so primitive, so BO's, and that's the sound of the 909 Clap!

The CP909 includes a high-powered output gain stage capable of producing hot signals. On the inputs, we have designed a pulse-shaper circuit so you can trigger the CP909 with trigger/gate signals from step sequencers, clock dividers, or any other pulse/clock sources. This eliminates the need to shape pulses sent to the module and ensures the same stable sound at peak power, regardless of your pulse source. Based on the architecture of the 909, the Accent input is versatile and able to take in both CV and Gate signals for continuously changing dynamics. All these unique features make integrating this legendary sound generator into your modular synth easy, unleashing the power of real analog drums.

Notes: 'Beast's Chalkboard' is dual channel stepped voltage source and adder for your eurorack modular synthesizer system. It primarily is intended as a dual octave switcher for VCO's but has many other uses including sequence transposition, FM ratio creation, buffered CV distribution and VCO calibration.

Technical Specifications:

Supply: +/-12V (Reverse voltage & polyfuse protection)
Current Draw: ~30ma
Size: 6 HP
Depth: 22mm (including power header)
Offset Error: +/- 10mV

Notes: Each of the two sections of the module is capable of performing the analog multiplication of two signals (A and B) and add an offset (C). It can also act as a dual voltage controlled attenuverter, dual ring modulator, dual VCA or four channel mixer (see block diagram below).

The B inputs are routed to an attenuverter that multiplies the signal between -2 to 2, while the offset inputs (C) route through a unity gain attenuverter (multiplies the signal between -1 and 1).

The output of first section is routed to the output of the second (when the first's output is unused), so the second output can act as master to achieve (A1*B1+C1) + (A2*B2+C2) or (A1 + C1) + (A2 + C2) - a 4 channel mixer.

The through-zero (four-quadrant) multipliers in the A*B+C allow for true Ring Modulation. To achieve this, simply connect two waveforms to the A and B inputs.

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

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

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

- 3U Eurorack module, 8 HP wide, 30 mm in depth
- Power consumption: 10 mA at +12 V and 10 mA at -12 V

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

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

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

Notes: The Stereo Triggered Sampler can record high quality stereo files, while simultaneously playing two different stereo files. A maximum of 600 samples can be loaded from the removable/swappable microSD card, in a variety of formats up to 96kHz/32-bit/stereo WAV. All sample parameters (1V/oct pitch, sample file selection, length, and start position) are CV controllable.

600 Samples:
A maximum of 600 samples can be loaded at once, arranged into banks of 10 samples each. Samples and banks can be re-arranged on the fly using the simple on-board Edit features. Newly recorded samples can be instantly played back and re-pitched, reversed, chopped up, etc... the result of which can even be bounced down and re-recorded to as a new sample! Sample files are limited to 4GB each, which is over 6 hours at 44k/16b/stereo.

Two Stereo Playback Channels:
Each playback channel has a knob and CV jack for Sample File selection, as well as a Start Position knob and CV jack for controlling where in the sample playback will begin. The Length knob and CV jack determine how much of the sample is played back: from tiny grains, to percussive hits, to longer loops... or just the entire file. These are powerful tools for re-arranging a sample, joining multiple samples, and creating dynamically re-sized loops within a larger sample. Combined with the Play Trigger jack and the 1V/oct jack, the STS can be two complete multi-timbral pitch-tracked stereo voices!
There's also a Reverse button and jack for backwards playback, and an End Out jack for synchronizing loops, or cascading sample playback with other events.

Looping and Sync:
Looping is easy: just hold the PLAY button down for two seconds to toggle loop or one-shot. The loop timing clock will output from the End Out jack. Or, send a clock into the Play Trig jack to sync the loop to external timing.

Stereo Recording:
Whether you patched 47 modules to create the ultimate percussive blast, or you want to capture your four hour ambient performance, recording high-quality .wav files on the STS is simple. Just hit the REC button or fire a trigger and a new stereo .wav file will be created on the SD card. Do as many takes as you need: the STS never deletes your files. Re-ordering or re-arranging samples into banks is easy, even without a computer.
You can even fill a bank with 10 different variations and immediately use them for playback.
By default the STS records at 44.1kHz/16-bit, with an option for 24-bit (a future update may increase the sample rate to 96kHz)

Easy sample loading:
Using a computer is completely optional with the STS, since samples can be recorded directly to the module and placed into the bank of your choosing. But for users with large existing sample banks, the intuitive automatic bank loading features make dragging and dropping your entire sample library a snap. You never have to rename your files again!

Notes: Killer physical modelling module collab from two of the biggest names in their respective fields of hardware and software. Generates a huge range of percussion instruments plus synths and bass tones.

Supplier's notes:
Plonk uses a technique known as physical modelling to synthesize, with great realism, the way in which sound is produced by acoustic instruments. The Plonk module is, itself, focused primarily on creating percussive sounds - both pitched and un-pitched; natural and unnatural; acoustic-sounding or totally electronic.

Plonk does this by breaking sound creation into two distinct elements - the exciter and the resonator. The exciter is a mathematical model of the device used to strike a particular surface. Plonk, because it's percussion oriented, has two types of exciters: one modelled on a mallet, and the other providing a noise source. The resonator is a virtualization of the object being struck, which vibrates, resonates and creates the body of a sound. Plonk offers several types of resonators: beam; marimba; drumhead; membrane; plate; and string.

Plonk provides numerous parameters that let you shape, mould and design both the exciter and the resonator, thus enabling you to synthesize the sound of striking or scraping almost any type of object - real or imagined. In this way, Plonk can accurately model the sounds of kicks, snares, toms, cymbals, claps, tablas, congas and all manner of traditional percussion instruments. It can also model pitched percussive instruments, like vibes, marimbas, and even bass or guitar-like tones. Of course, it additionally excels at modelling instruments that heretofore never existed.

Best of all, the sounds created by Plonk are not static - any sound you design can respond dynamically to velocity, as well as four different modulation inputs. This means the sound of Plonk can change completely from note-to-note (or strike-to-strike). Because of this, Plonk is actually a duophonic (2-voice) module, which lets the sound of one note decay naturally when a second note (possibly employing an entirely different set of modelling values) is struck. Thus, hitting a new note does not choke the sound of the previously struck note (unless you want it to, of course)!

Plonk stores up to 128 patches in its internal memory, and ships with many presets programmed by professional sound designers and composers. You may overwrite these patches if you wish, and banks of patches may be transferred via MIDI System Exclusive over Plonk's built-in mini-USB port to facilitate offline storage by programs or websites that support this capability.

Plonk was developed in cooperation with Montreal-based Applied Acoustics Systems - physical modelling pioneers, and the creators of Tassman, Lounge Lizard, String Studio, Ultra Analog, Chromaphone and numerous other plugins. It is with great pleasure that Intellijel brings the potential of this physical modelling technology to a hands-on, CV-laden device capable of the sort of dynamic control and sonic exploration that modular synthesists demand.

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

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

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

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

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

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

Notes: Mission Control

All the essentials to control and sync your Eurorack modular from your computer, iPhone/iPad, or hardware MIDI device. No menu diving or configuration scripts, just two buttons. Get crazy with external modulation and sequencers, or just sync your rack's clock from the rest of your MIDI bus.

Notes: Two independent Contour Envelope Generators in a single 12hp wide Eurorack module. These are very accurate replicas of the Model D contour generators, with identical circuitry and component values running on the correct +9.3V and -10v supply voltages of the original; so they exactly replicate the original envelope response along with all of it eccentricities. Extra features include manual trigger buttons and envelope status LED's.

The contour generators played a larger part in the sound of the Model D than many people realise. There are two factors that make them unique, firstly the exponential slope when is used in conjunction with the (near) linear slope of the original VCA which is responsible for the famous Model D "punch". Secondly, the re-trigger behaviour is quite unique, multiple retriggering increases the output level so that either the volume increases incrementally, or the filter opens incrementally with each extra key press.

AJH Synth have added independent Decay switches for each individual Contour Generator rather than the shared switch on the original synthesiser, these switches change the Contour response from AD (switch up) to ADSD mode (switch down).

Notes: Full-featured triangle core VCO/LFO

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

Notes: A simple noise generator and 4 band fixed filter bank.

The noise is normalled to the Filterbank input. The cutoff frequencies are matched to the Bark Filter, so that four bands of the Bark Filter correspond to a band on the Noise & Filter.

It is a small and quick noise source and pairs well with Scan & Pan and Amp & Tone.

HP : 4

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

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

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

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

HP : 4

Notes: A multi-mode divider for clock and audio signals.

It can be used either for dividing clock signals (e.g. from an LFO, BEATDIVIDER) for rhythmical purposes but also for audio signals - in this case you get subharmonics / lower octaves squarewaves at the outputs, which can be mixed or used separately.

The module has eight outputs which - depending on the selected division mode - provide different division factors of the input signal:

Beat: musical/rhythmical clocks are generated as 1/1, 1/2, 1/4... 1/16 and triplets
Binary: the outputs work as binary counter (same as the predecessor module DIVIDER)
Decimal: The outputs have decimal divisions of the input, meaning half, third, quarter, fifth... of the input clock
Prime: The outputs use the prime numbers as division factors
Fibonacci: The outputs use the numbers of the fibonacci row as division factors

The reset input resets all output signals; in case of audio signals this can get quite unique, ringmodulator-like sounds.

The Shift knob shifts/rotates the outputs; usually, the fastest output is on output 1, but with shift the entire output pattern is shifted so the fastest output can be set to any position 1...8.

Notes: The SCM Plus is a clock multiplier with eight gate outputs and complex beat manipulation features. It combines the classic Shuffling Clock Multiplier (SCM) and SCM Breakout (SCMBO) into a single module using higher precision hardware than its predecessors.

Enter the Behringer CP35 ATTENUATORS Module. An authentic reproduction of the circuitry from the Modular 55, 35 and 15 Series used by the world's most famous pop, rock and jazz musicians. Now, musicians can build their very own, unique, synthesizer that can fit in a standard Eurorack case for a very affordable price. Mix and match specific modules to create your personal, unique synth to complement the music you play or go all out and fill a room, from floor to ceiling, with modules that'll fulfill any synth geek's wildest dream.

The CP35 features 4 passive attenuators with linked inputs and 4 separate outputs. Each attenuator knob can be used to adjust the level of the input signal passively from - 8 to unity gain. Connecting a single signal to the first input will allow it to pass to all 4 outputs to have up to 4 variations of a single signal source. Introducing a signal into the subsequent outputs will break the chain from the previous input. For example, if you have a signal in input 2, then this will feed into input 3 and 4 leaving input 1 to feed out of output 1. Having multiple inputs allows you to attenuate 4 separate signals and be more flexible with your tone.

Along with the standard outputs, the CP35 also features 6-volt outputs. These outputs give a reference voltage of -6 Volts out of one pair and +6 Volts out the other. Also included are two banks of 4-point multiple circuits for you to be able to route multiple copies of input signals to other modules. The CP35 can be a powerful addition to your synthesizer rig by allowing you to have multiple sources output to multiple modules so you can shape and sculpt sounds that are sure to blow everyone away!

Installing the CP35 is simple as it was designed to fit into a standard Eurorack case. Just connect the power cables to the power supply and screw in the module using the included screws. This allows for the CP35 to be mixed with other synth modules for a truly unique set up.

Notes: The Tone Science Chance Delay is a unique concept in Eurorack modules as it combines chance and randomness, with pulse delay and pulse conditioning. It is a collaboration between electronic musician/composer Ian Boddy and AJH Synth.

It can perform as a Chance generator, but is also capable of pulse stretching for Trigger to Gate conversion, pulse shortening for Gate to Trigger conversion, Gate Delay, Sub Bass Generation and also "divide by n" clock division.

There is a wide range of control and all functions can be operated manually from the front panel or can be automated using external CV voltages. Chance can range between 0 to 100%. The Gate out can be delayed by anywhere between from 0.5mS to 30 Seconds, and the output Pulse length can also vary from 0.5mS to 30 Seconds.

The TRIG push button allows manual triggering of pulses, also determined by the Chance control, and a green LED shows the output pulse status.

Includes a handy "Gate pass through" mode; when the Length control is set to zero the incoming pulse or trigger will still be determined by the Chance and Delay controls, whilst the outgoing gate length will be the same as the incoming gate length.

Compact 8hp form factor and very low power consumption make this an excellent addition to any Eurorack system.

Key features:

Chance, Gate Delay time and Pulse Length can all be set manually or controlled using external CV voltages.

The 'TRIG' push button allows manual triggering, and Chance will be applied to any manual triggering too.

Fast processing allows operation into the lower audio range, so it can perform sub bass generation on drone type sounds. In this mode the Length pot (or an external Length CV) can be used to change the PWM of the output waveform.

After the initial trigger pulse has been acted on, further incoming pulses are ignored until the current cycle has finished. This useful feature allows it to perform "divide by n" division on gate pulses, so it can be used for clock division, and the delay function can be used to add a "swing" away from the rhythm.

Gate pass through mode - if the Length pot is set to zero, then the incoming gate length is preserved, so in this case the gate has Chance and Delay time applied to it, but the outgoing gate length is the same as the incoming gate length.

By setting Chance to 100% and Delay to zero (0.5mS) it can be used as a Gate to Trigger converter, or a Trigger to Gate converter, depending on the Pulse length set with the LENGTH control. We can also use an external Length CV to shorten or increase the length of the output pulse in real time.

Fast and slow ranges for both DELAY time and PULSE length - Fast range is 0.5mS to 2 Sec and Slow Range is 2 Sec to 30 Sec.

Green status LED shows when the output pulse is high.

Front panel controls

Chance Control and CHA Input

This sets the probability of an incoming trigger or gate being passed through to the Pulse Generator circuit. The chance can be set anywhere between 0% and 100%.

The CHA input allows an external control voltage (CV) to control chance remotely. In this mode the Chance control acts as an attenuator for the incoming CV. With the Chance control fully clockwise a CV of +5V will give 100% chance, and lower CV voltages reduce the Chance accordingly. For example, a +2.5V CV will give a 50% chance. The attenuator function is useful if we are using higher control voltages of for example 0 to +10V. If we set the Chance control to the 12 o'clock position it would then halve the incoming CV signal, so in this case +10V will give 100% chance and +5V will give a 50% chance. Negative CV voltages are ignored and will be treated in the same way as zero volts..

Delay Control and DEL Input

This sets the delay amount that is applied to the leading edge of the incoming Gate or trigger received at the IN jack (or a press of the Manual Trigger button), assuming that the "Chance" has been determined to be positive. With the Delay Time switch set to FAST the Delay range will be from 0.5mS to 2 Seconds. With the Delay Time switch set to SLOW the Delay range will be between 2 Seconds and 30 Seconds.

The DEL input allows an external CV voltage to control Delay Time remotely. In this mode the Delay control acts as an attenuator for the incoming CV. With the Delay control fully clockwise a CV of +5V will give the maximum Delay time of either 2 Seconds or 30 seconds depending on the position of the Fast / Slow switch. Lower CV voltages reduce the Delay Time accordingly, so if we apply a CV of zero volts then we will get the minimum Delay time. The attenuator works on any CV patched to the DEL input in the same manner as described for the Chance control.

Length Control and LEN Input

This sets the length, or rather pulse width of the output pulse. With the LENGTH Switch set to FAST the pulse length can be anywhere between 0.5 mS to 2 Seconds. With the LENGTH Switch set to SLOW the pulse length can be between 2 seconds and 30 Seconds.

The LEN input allows an external CV to control Delay Time remotely. In this mode the Length control acts as an attenuator for the incoming CV in the same manner as the Chance and Delay controls.

Setting the Length control to zero invokes "Gate pass through" mode - in this case the incoming gate length is preserved, so the incoming pulse or trigger will still be affected by the Chance and Delay controls, but the outgoing gate length will be the same as the incoming gate length. Turning the Length control slightly clockwise will then invoke the minimum pulse length around control position 1, and further clockwise rotation will increase the Pulse Length as expected. This behaviour also applies to external CV's patched to the LEN input, where a CV of 0V will enable Gate pass through mode.

Fast / Slow mode switches

These switches allow the selection of Fast or Slow mode for Delay time and pulse length, so these ranges can be selected independently for Delay and Length. Fast range is 0.5 mS to 2 Seconds, and Slow range is 2 Seconds to 30 Seconds.

TRIG Switch

The TRIG push button allows manual triggering, and Chance will also be applied to any manual triggering, so depending on the setting of the Chance control, pressing the button has a chance of not doing anything! Holding the button down keeps the incoming gate high for as long as the button is pressed, however this is only really relevant in "Gate pass through" mode - normally only the leading edge of the input pulse is used.

IN - input jack

Connect your input here - a gate, output from an LFO, or even waveforms from a VCO. Any negative component of the input voltage will be ignored, so unipolar or bipolar signals can be used.

OUT - output jack

This outputs the binary pulse (or stream of pulses) that are generated by the Chance Delay circuitry. The gate low level is 0V and gate high level is +6V. The green status LED shows if a pulse is currently being generated.

3 blocks of 2-channel attenuverting mixers, using dual concentric pots. Each channel can be switched to mix with the subsequent channel, allowing for 2-2-2, 4-2, 6 mix configurations.

With nothing plugged into an input, an offset is normalled to that channel. The inner knobs control the A inputs, while the outer knobs control the B inputs.

Notes: CV Random is a random CV generator with 4 types of randomness and a triggerable sample-and-hold function.

Sliders allow you to set the internal clock tempo (RATE), shape the probability of triggering (PROB), blend old with new values (RND) and set the shape of all four random outputs (SHAPE).

4 different sliders

RATE

Sets the tempo of the internal clock. The CV input below the slider adjusts the clock rate, with 1V/oct calibration when the CV attenuverter is 100%. Upon each clock trigger, the RATE slider light blinks, and there is a chance for the internal random source to generate a new value.

PROB

This probability is set by the PROB slider, and if a new value was generated, the PROB slider light blinks and a pulse is emitted from the TRIG output.

RND

When the internal random source generates a new value, it mixes the previous value with a random value, with an amount specified by the RND slider.

SHAPE

The SHAPE slider sets the shape of all four random outputs. At its lowest position (0%), all outputs immediately jump to the new random value (the target value) when the clock is triggered.

At non-zero positions, the outputs interpolate between the previous and the target value, using a different behaviour for each output.

Internal random clock source

Whenever the clock activates, the RATE slider's light flashes. At the same time, there's a chance that the internal random source will create a new value, depending on the PROB slider's setting.

If it does create a new value, the PROB slider's light flashes too, and a pulse comes out of the TRIG output.

External IN & TRIG inputs

If the TRIG input is patched, the RATE slider is ignored, and the internal clock is only triggered when an external trigger is received. The PROB slider is used to filter this trigger by applying some probability.

Self-modulation

Thanks to a switch in the back of the module, you can normalize the LIN output to the 4 CV inputs and adjust the amount of modulation for each parameter with the attenuverters.

This adds another layer of randomness to your results, enabling more dynamic and unpredictable outcomes.

SHAPE Outputs

The STEP output jumps to the new value in one step at 0% SHAPE, and divides the transition into 16 steps at 100% SHAPE.

The LIN output immediately reaches the new value at 0% SHAPE, and takes the whole clock cycle to do so at 100% SHAPE, staying constant in between.

The EXP output shifts exponentially, becoming linear at 100% SHAPE, with its pace adjusted by the SHAPE slider.

The SMTH output transitions smoothly, with the speed controlled by the SHAPE setting, holding at the target until the cycle ends.

Notes: The S1 is a promotional bundle that Tiptop Audio is offering to users, providing a 33% savings to get you started with ART. With these bundles, this incredible voice is included: the big, beefy 3 VCO stack. The bundles come in two options: Bundle S1, which uses the ART V/OCT Quantizer as a controller, and Bundle S2, which uses Octopus as a controller. In addition to the controllers, there are three ATX1 analogue oscillators, MIX7 for mixing them with plenty of headroom, and followed by the beloved 4-pole Z2040 filter that has been with TipTop since day one; it just sounds so good. Finally, we end up with Control Path dual envelope plus VCA dynamics modules. This special price is time limited and while supplies last.

ART QUAD QUANTIZER is a four channel CV to ART Quantizer to play ART oscillators from CV sequencers, LFOs and anything that outputs CV. This is Tiptop's second ART controller option and is designed for those of us playing ART without a computer or MIDI source. The inputs take in positive, negative, bipolar CV voltages. Scales include Major Minor and the five other modes (Dorian, Lydian, etc). The module is simple to set up with a simple menu and one knob with switch for navigation. The 4th channel can be set to generate Chords and polyphonic note streams for ART Polyphonic oscillators.

ATX1: a classic all analogue saw VCO core with 3 switchable modes, ART, 1V/Oct, LFO and is recommended as the basic building block for ART systems. It is designed for patching analogue polyphonic synths from discrete modules or multi-mono patches in ART mode. When using ART the ATX1 takes care of the tuning including accounting for temperature changes. In 1V/Oct mode the ATX1 runs as a standard old school modular VCO. LFO mode drops the frequency range and is great for patching vibrato to other ATX1s among other things. The ATX1 outputs variable waveshapes with manual or CV control. Classic FM, PWM and hard sync are provided. A dedicated Gate Out in ART mode manages the voice envelopes or any modulation synced to that voice. TipTop consider the ATX1 the best sounding analogue VCO they have ever created.

MIX7 is a seven channel analogue summing mixer module for Eurorack. It is designed for summing any of the different types of signals you'll find in a modular system: Audio, CV, Triggers, or Gate.

MIX7 gives ability to sweeten your mix with more headroom using the power of low noise analogue summing. A compact 3HP Eurorack utility module, MIX7 is an attractive mixing addition to any rig, especially with the ability to also combine rhythms, note patterns or CV automations from different control sources. The main output of one section can be connected to the input of another MIX7 to create larger mixing groups and complex signal routes inside your modular.

The MIX7 summing mixing circuit is built with low-noise operational amplifiers, giving it an excellent sound quality for mixing audio, the beautiful texture of classic analogue mixing with plenty of headroom to handle hot modular signals, and the versatility to sum non-audio signals in your system to open up new creative possibilities.

Each input is labelled with a number of dots, 1-7, yellow for input and green for output. The module matches Tiptop's system look with clean white faceplate styling.

At the back of the module is a user-configurable jumper allowing users to configure the MIX7 for either unity gain (OUT = IN) or give increased headroom (OUT = 0.4IN) for use with hot audio signals, which makes it a great pairing for Tiptop Audio percussive modules. A peak indicator light on the front panel warns the user of even the slightest audio clipping in the mix, helping to keep all the incoming sound sources at their full original quality.

Size: 3HP - Depth: 43mm - Power: +12V 25ma / -12V 20ma

CONTROL PATH is an all in one voice dynamics module that helps build full voices quickly. It contains two analogue envelopes with velocity cv, and one VCA. In a typical voice patch the left envelope will control a filter and the right envelope will be the voice VCA. Velocity control is provided for each envelope and delay front panel trimmers are used to compensate for any miss match between incoming gate signal and velocity CV timings. Envelope cv outs are 0-5V, Velocity cv ins are 0-5V.

Power: +12V 50mA / -12V 55mA

The Z2040 is TipTop's redesign of the most famous analogue filter from the polysynths of the 80's and features Tiptop Audio's signature lush, big, and creamy sound. Its frequency sweeps make thick bass lines and leads with great dynamics. When modulated with audio frequencies through its various inputs, the Z2040 gets quite colourful and is capable of creating many new sounds and textures as the forces of the incoming waves and their harmonics blend through the filter's non-linear circuit. When set with Resonance feedback fully up, the Z2040 transforms into a pure sine-core VC-Oscillator, great for making snappy percussive elements and whistling sounds.

A look under the hood will find that the heart of the Z2040 is a discrete design 4-pole low pass filter with a core similar to that of the SSM2040 filter chip, used in the 80's Prophet 5 Rev 2 synthesizer, and its brother the SSM2044, used in the famous early EMU samplers and PPG synthesizers of the 80's. Both filters are considered by many to be, "the best sounding filter ever".

The Z2040's four modulation inputs are built to handle CV and audio signals, enabling deep modulation of the filter core and passing signals. A VC resonance input is provided to modulate and even clip the sine wave produced by the filter feedback loop. A Frequency Modulation input (FM) provides dynamic filter sweeps and the unique VC-FM index allows modulation of the incoming FM signals. On top of that, the Z2040 comes with an audio VCA that can be configured to act upon the input or the output of the filter.

OCTOPUS is a powerhouse ART controller that takes MIDI in via the USB or DIN connector and outputs 8 ART channels with 8 velocity CV plus 8 drum triggers. Together with the ART oscillators the OCTOPUS provide unprecedented simplicity connecting the modular to your computer sequencers, hardware midi sequencers and keyboards. Each ART channel can play polyphonic notes, monophonic notes or create multi-channel polyphony using an internal voice manager. All together OCTOPUS can play more voices and notes from a single controller than ever was possible in modular. Using ART high speed control signals OCTOPUS can maintain low jitter for tight timing. OCTOPUS is TipTop's first ART controller with more to follow, please select between Octopus or ART V/Oct Quantizer to get started with ART. Please note, OCTOPUS is not a 1V/Oct midi to CV and should not be confused as one.

Notes: Endless Processor (Ex)pander Kit opens new possibilities for Endless Processor!

Now, there is pitch control over both channels. You can shift one octave up or shift down to a full sound stop, covering multiple octaves, effectively replicating the variable speed replay effect. This allows for the creation of new textures from existing sounds.

Additionally, with the expansion PCB, the Endless Processor gains an SD card slot that enables you to store up to 5 sound banks. This means everything sustained in both channels can be saved to preserve those happy accidents! However, this is not just a simple save and recall process. It allows more performing possibilities: sustain new sounds, play with them, and then recall the stored ones, all with respect to the fade controls.

And if that's not enough, there's a bonus! With the help of our web tool, you can upload the sound banks saved on the SD card and extract clickless loops of each layer in WAV format. You can then import these loops into your DAW or hardware sampler to build your composition on top of the captured sounds.

Endless Processor Expander Kit contains:

Endless Processor Ex module
Expansion PCB for the Endless Processor
Cable to connect Ex module to the expansion PCB

Width: 4HP

Depth of Endless Processor with expansion PCB attached: 45mm

Depth of Endless Processor Ex module: 30mm
