Boomtschak - one of the most powerful entirely analog drum voices in Eurorack. As sound sources it uses an oscillator with waveshaper, a filtered noise or the mix of both. Not less than three flexible envelope generators are included, for pitch bending and the amplifiers. The resonant multi-mode filter can be fed with external audio signals instead the noise generator. The module's frequency range is huge, thus allowing for using it as a synthesizer voice.

This digital module is specialized in one effect only: thick, juicy and fantastic chorus, thanks to automatic routing ieven in true stereo. It offers internal modulation, feedback and has two different chorus modes whose slightly different sound you might already know from the Audio Damage plug-ins Fluid and Dimensions.
The module's DSP works with proper 24Bit and 48kHz and also the mechanical quality is rock-solid.

Dub Junior's Mk2 version also is based in the delay algorithms used in the Audio Damage Plug In Dubstation and the old DubJr module but it has been clearly enhanced and improved regarding as well the features as the mechanical quality. It is a delay module with clock synchronization and tap-tempo, 24Bit/48kHz quality, two modes, two timpbres and external feedback loop. A worthy successor to the best-selling, venerable DubJr.

Room simulation in studio quality – EOS features two superbly sounding, flexibly editable reverb algorithms. Plate is perfectly suited for refining drum, percussion and effect sounds as well as the human voice. Superhall delivers subtle and cold to voluminous, softly wafting results. – An excellent choice for giving leads, pads or atmospheres that certain something. Using the freeze function, it is possible to generate huge, endless walls of reverb. In general, EOS can be characterized as a dense sounding effect with high resolution. It is on a par with far more expensive studio processors.

The Errorbox module uses three digital distortion techniques to mangle your signals: sample rate reduction, bit rate reduction and an unique Error effect. The results range from slight vintage digital flavour to total destruction

Audio Damage brings you the Neuron a versatile digital drum voice, sounding good and being utterly flexible. The by-name "FM Drum Voice" is a slight understatement because besides FM sounds the module can do pretty much everything from the electro drum kit: filtered noise makes snare drums possible, a wide frequency range allows for kicks, toms and more, FM provides you with anythind metallic, cymbals and effect sounds. A 2-in-1 distortion and a pitch envelope is abord, too.

Odio is a very functional 2-IN 2-OUT USB audio interface that runs at modular audio levels, designed primarily for use with iOS devices but it works also with Windows and Linux.
Easily integrate iPad effects and instruments in to your modular rig. Use a netbook/tablet and a simple host to use VST plug-in effects as inserts in your modular.
The Odio's outputs are DC cupled and can emit CVs.

Although the Proton makes for a pretty nice delay its main focus of attention is a type of physical modeling called Karplus-Strong synthesis. It creates percussive sounds which resemple a plucked nylon strong but Proton is able to twist them in a strong way by filtering and by adding noise impulses.

Besides true stereo wave shaping the digital Shapes module offers the possiblity to scan one of 16 interpolated wavetables using audio and CV inputs. To do this you can induct any input signal, from a sine oscillator to an entire stereo sum, whereupon the grade of erosion or destruction rises with the complexity of the audio material.

Unlike 007 in Spectre it won't shoot people when you but it will freeze a frequenc spectrum when you use the trigger. Spectre by Audio Damage is a Fast Fourier Transformation (FFT) based effect module which captures the audio signal and is able to freeze its frequency spectrum. The frozen signal can be pitch shifted, spread in the stereo panorama and mixed with the original to create tuned drones, glitchy spheres, vocal sounds, trippy drums and much more.

The Æverb Mk2 is a digital reverb processor with extremely dense sound. Its results are rather unrealistic, yet very atmospheric. The user can choose between two reverb algorithms. All effect parameters feature CV inputs. Two audio inputs and outputs make the Æverb Mk2 a true stereo processor.

Not available for an uncertain time.

The CED module on one hand is used as an oscillator tuner with two different modes of operation and a LED chain for visualsation, on the other hand it can be a sub octave generator with adjustable octave. That's two modules in two HP only!

Voltage controlled multi mode filter of state variable topology. Not only being small in size but also sounding very tasty and unique. The slopes are rather flat with -12 and -6dB, providing for a rather smooth sound, unless you actvate the switches for the special parameters for resonance character and overdrive, as it will get wild, gnarly and dirty.

Really odd and unconventional module combining and intertwining an envelope follower, a rectifier, a comparator and a voltage controllable switch.
You may ask: What for? Well, for extracting gates from an audio signal. For generating a compressor curve CV which turns any better VCA into a flexible compressor. Or for creating a "fake" Thru-Zero modulation!
The individual sections can be used separately of course.

Jimi Hendrikson would have had a lot of fun which this module, processing his guitar with a modular system or connecting his stomp boxes.
The module is versatile; it can be either a pre-amplifier for guitars and other instruments or a interface for external effects with voltage control of the dry/wet mix. You might as well realize a voltage controllable feedback loop with external effects.

Versatile six-track trigger/gate sequencer which offers up to 256 steps per pattern, yet remaining the fast and easy-to-use workflow of a classic 16-step sequencer. The solution is a smart partition into pattern, bar, step and sub-step as well as very useful functions like clear, copy/paste and undo.
What else: mute per voice, clock generator, step repetition, saving everything on microSD card, record function.

Bastl call it to the point a "trigger toolie", to be exact this module is a multi-channel processor for clocks, triggers and gates. It has two sections which can be coupled or used individually. In total there are five outputs processing input signals in a different way: by clock delay, clock division or clock multiplication, trigger repetition but also in form of a euclidian sequencer, a probability based groove generator and finally a clock oscillator.

The popular MicroGranny2 is a monophonic standalone granular sampler/sample player in miniature format. It records and can read WAV files from microsD card and processes it via granular algorithms. Adjustable parameters are start and end point of the sample as well its sample rate and bit crushing - for modulation an attack-decay envelope generator is available. Via MIDI you can control all parameters, transpose the sample or play different grains by individual notes.
The unit has an Arduino chip which can be hacked.

The name is a nice pun referring to the capabilities of the module: "noise²" alias "squared noise" points to the two types of noise generators in the module: analog and digital. "Square" by itself refers to the square wave generation the module is capable of.
All these signals are especially but not exclusively suitable as base for drum sounds.

An unusual, because non-linear sequencer concept. The eight steps can be addressed in a number of ways: by several trigger signals which go one or more steps forward or backward, by using control voltages or even with three binary gates. A control voltage input is included as well, either transponsing the pitch quantized / non-quantized or or even to change the quantiser's scale from major to minor.

Not another clone of a far-east TR bass drum, as one might think, but something entirely different: an electronic hobbyist's true vintage Eastern Bloc design from the times of the communist Chechoslovakia.
It has voltage controllable tuning, adjustable resonance and click as well as a number of parallel audio outputs for a number of drum sounds. Pretty interesting and versatile drum voice with a wide frequency range which can be used as a weird oscillator as well.

Tromso contains three separately useable circuits: a voltage controlled triangle wave oscillator, a comparator and finally a sample & hold which can be used as a track & hold alternatively.
So far it is a handy small tool but normalizations between the individual sections make it even more interesting because in this case the module is great for analog downsampling of audio signals i.e. as a sample rate reducer.

This module is a small revolution as it integrates a modular idea from recording gear into Eurorck. It makes it possible to use up to three interchangeable saturation Colour circuit boards from the "Colour 500-Series Palette", an API 500 form factor device, into Eurorack. With voltage control of level, and with the prospective ColourCV boards even with voltage control of parameters!
Well, it's a module with a modular idea behind it, interchangeable timbres like saturation of transformers, behaviour of vintage audio gear to effect simulation.

The bundle contains one ColourPalette module and the two ColorCVs Woof and Tweet.

Analog oscillator with a very own approach and that is two independent frequency control circuits beetween which the VCO can switch autonomously. This alters both the sound and frequency ratios, created glitches and new wave forms. An AM input is used, depending on a pot's setting, as a extra audio input or a the modulation signal for the awesome ringmodulator.
Difficult to describe but very unique and interesting!

Version with minijacks

This desktop unit is a clone of the wild and nasty filter circuit from the vintage russian Polivoks synthesizer. It is built with genuine russian ICs and the sound circuit is 100% analog.
What makes the Acidbox really briliant is the mighty versatile LFO with synchronisation, tap tempo, plenty of wave forms, waveshaping and tempo multiplication/division. This totally invites you to jam with the unit instantly! Hot stuff!

Very authentic emulation of the voltage controlled low-/bandpass filter from the russian Formanta Polivoks synthesizer. Although the circuitry was adapted to modern modular systems and the low-end's behaviour was enhanced, the module's heart still are the original intedrated circuits K140UD12 responsible for the filter's special sound with it's wicked resonance.

Versatile clone of the russian Polyvoks synthesizer's filter with some fancy extras. The resonance is voltage controllable, both the filter slope of the lowpass respective the bandpass width is adjustable with a potentiometer as is the resonance behaviour. With these functions the D-Tech filter can produce both smooth, ballsy sound but also Polyvoks resonant screams, so typical for the Polivoks. Have it your way. And the module is really adequate for creating very wonderful, wooden drum sounds by "pinging" the filter.

Precise duophonic MIDI/CV interface with 16Bit converters, directly adjustable Glide, a tune potentiometer and two FM/transpose inputs. The special feature is aparaphonic mode which exactly simulates the behaviour of an ARP Odyssey or a Formanta Polivoks exactly - it's a duophonic mode where a single gate is produced no matter which of the two keys is pressed.

Not in production anymore.

This is not the first tube ring modulator in Eurorack form factor but probably one of the smallest. It uses a 6ZP1 pentode tube which reacts quickly to CVs and clearly has a tubish sound without being too extreme. Use the module as a ring mod, as a VCA or just for adding some tube flavour to your audio.

Small 6V AC power supply which must be installed if you want to use Erica Fusion V1tube modules. Advantage is that the tubes won't draw energy from your main Eurorack power supply when heating up.
One Fusion V1 power supply can provide enough energy for the heaters of up to seven Fusion V1 tube modules.

This module contains two three-channel tube mixers which have been designed specially for direct mixing of VCO waveforms. Because of the tube sound and it' saturation behaviour this module can be used as a fine waveshaper, which can sounds pretty brutal when 3 VCOs are mixed at high levels. Especially living waveforms with constantly changing harmonic content like PWM will be heavily processed by the tube.

Truly deluxe matrix mixer with touchscreen operation, 250 memory slots and buffered outputs. Several presets can be chained and sequentially switched with a clock signal

Erica's Sequential Switch module together with it's control interface is unique and it's features set it apart from others. Each of the eight channels can be turned on and off individually or be skipped, can output a gate and be merged with the adjacent channel to generate tied gates.
The module makes it possible to create sound and clock sequences, to switch signals or to send one audio source to eight different destinations sequentially.

Arpeggiator module containing two arpeggiator channels for bass and melody. Each arpeggiator´s pitch and clock (or gate) are available at individual outputs. The first four notes of the melody arpeggio (ARP) are output as chord at four dedicated CV outputs 1-4. With the miniature keyboard notes can be entered directly as cords or scales, The included expansion module X-2013 allows you to output the arpeggios via MIDI, to sync the module to MIDI clock and gives 8 clock outputs for sequencer tracks.

Not in production anymore

The first Fonitronik module is the Attenuverting Mixer. It is primarily a four-into-one mixer module for control voltages (and audio signals of course) but besides of that it has some sub-functions like attenuator, controlable inverter and generator of offset voltages.
