Sample player module that plays up to 72 samples (WAV file, 22kHz, 16Bit, mono) from a SD card! You can control following parameters manually or via CV: Loop size, file position, sample rate and optionally the amplitude due to the integrated VCA. An envelope follower is there as well. Different sounds can be accessed by skipping or randomizing playback files, which can also be accomplished both manually or through a CV input.

We don't offer this product anymore.

Stereo FM radio receiver in Eurorack module format. The parameters frequency and volume can be voltage controlled. Seek and search can be activated with gate and trigger voltages, same for the mute function.

Compact module with two dual-channel oscilloscopes displayed with high-contrast OLED dsisplays. Each oscilloscope can also generate arbitrary waveforms with 8Bit resolution and 44.1kHz sampling rate.

The ADDAC501 does random CV generation and outputs it through three independent channels. You can control the desired range of voltages and time frequency at which new values are generated.

It can also be triggered by an external CV source and the output voltages can be either free or quantized. Finally you can choose between pure randomness or a brownian distribution, for both the voltage and time intervals.

The ADDAC501 does random CV generation and outputs it through four independent channels. You can control the desired range of voltages and time frequency at which new values are generated.
It can also be triggered by an external CV source or the internal clock and the output voltages can be either free or quantized (if you prefer to have a standard C Major Pentatonic scale).

The ADDAC 601 module is an analog fixed filter bank with eight frequency bands. Each band features voltage control of amplitude and a separate envelope follower. A number of audio outputs and many possibilities make this filter bank a superior unit.

ADDAC´s 701 VCO is a fully analog, stable, voltage controlled oscillator with a very wide frequency range.

This module integrates any iOS device (like iPad, iPod or iPhone) into your modular system in order to send and receive audio signals between both machines by the duplex audio connector of the iOS unit.

Set with five quality patchcords by Cliff, 15cm long. Each one cable in green, yellow, blue, red and white.

RS-190 is out of production

The RS-190 combines a real analog VU meter with an inverter

Faithful reproduction of the legendary and rare analog frequency shifter from the Moog modular system, designed by Harald Bode. The RS-240impresses with features like exponential and linear shifting scales, integrated squelch circuitry, very clear sound and several audio outputs ... yeah, and by that HUGE knob ;)

The expansion module for the ADSRjr by Circuit Abbey adds serveral features to the main module: voltage control of envlope segment times, directly switchable curve characteristics and additional outputs.

A pre-amplifier module specially designed for the use with guitars. It comes with a three-band equalizer and can be used both with active or passive guitars. The sound is transparent but it can clip nicely.

Flexible clock divider with eight outputs and eight different modes like binary counting, divide by odd factors, by prime numbers, random modes and so on. It can output either triggers or gates.

Circuit Abbey Gozinta gives you two separate adjustable preamplifier units to boost the level of any line signal to modular level. The thing sounds clean because of the use of high quality, clean and supermodern amplifier ICs.

The Gravity Well is an unusual Eurorack module that asymetrically warps signals. This happens on several axis with different strengths. Imagine the input signal being an object circulating around a heavenly body. CVs can change the circular path by altering the body´s strength of gravity, vayring the gravity field and affecting the north-south and the east-west magnitudes.

The Impulse Drive module is a very unique wave shaper as it generates harmonically complex sounds by crossfading between signals, triple pulsewave generation and by cross modulation.

Mix expander module initially developed as expander for the G8 by Circuit Abbey. But it works also with Livewire's Chaos Computer and with the QPLFO by 4ms. The Intermix mixes the outputs of the mentioned modules either as a eicht-channel mixer or as a dual four-channel mixer and in addition it has a min/max function.

Single unit

Invy is a dual voltage procressor for attenuating and inverting signals and for creating offset voltages. Normalizing and mixing features allow for a number of applications.

The TripFire Eurorack module by Circuit Abbey is a very handy, compact dual module. The top unit is a comparator for extracting gates from external signals, the bottom unit is a gate- or trigger-delay and thus the module is excellent for creating rhythmical signals, trigger envelopes etc.

Two clean ring modulators in just two HP? Skinny Twiggy makes it possible!

UNIFY is a high quality, four channel Stereo mixer module with selectable output level, panorama pots per channel and a headphone output with separate level control. It´s very well suited as the final mixer in your Eurorack system.

The Unify input expander adds four input channels to the Circuit Abbey Unify module. Up to three expanders can be connected to one Unify which gives a maximum of 16 input channels

VacVac contains two VCA circuits working with Vactrols. Those who like to have the oganic percussive behaviour of a lopass gate in a true VCA, but search for something smaller and simpler than an Optomix might like this module.

We have one very last unit in stock - and they won´t come again!

Sounds really nice and fuzzy from soft to hard. A bit dry and in a postive way amputated - kills the overtones a little bit and makes the distortion sounding more round - a solid little box in a pure metal case and a nice sticker on it - a beauty on its own

Runs on a 9v battery, 1/4" in and output.

One last unit in stock.

Creative eight step pulse sequencer with random and one-shot modes and adjustable loop cycle length, number of repeats and step length. The module can be coupled with other Algorhythms to create longer patterns or to cross-influence the sequencers which can be interesting for polyrhythmics or odd time signatures.

Sync Gen 2 LS is a module for sample-accurate rhythmical pulse synchronisation between your DAW and your Eurorack modular system. Or in simple words: for creating a perfect clock from your computer!
The clock is available at several minijack sockets and in addition there is a MIDI clock output and a DIN-Sync output!

Having been split up in three components the sync shifter is serving many conversion problems offering you better timings and grooves just in time while using midi and sync24/Din sync based hardware.

The bigger version of Innerclock's Sync-Gen again generates a very stable MIDI clock via your computer's audio interface but it has been expanded by a number of MIDI Clock outputs and even DIN Sync outputs.

The Kenton Midi Stream allows for easy-to-use transmitting any MIDI data via radio

The system consists of a compact transmitter of the size of a cigarette box and a receiver which can be rackmounted. Thus it´s perfectly suited to use a portable keyboard without cables live on stage.

Expansion module for the E350 Morphing terrarium by Synthesis Technology. It adds two functions that otherwise are only accessible via jupers on the backside of the E350 and has an attenuator in addition.

Out of production.

This module is a so-called OR-combiner i.e. a circuitry that mixes trigger and gate signals. The mutinator contains four, partially normalized channels with each two inputs that can be manually routed or muted. It works great in combination with drum modules and several trigger sources like sequencers etc.

Very small yet powerful digital sequencer with variable sequence lenght, in-built clock divider, quantizer, arpeggiation, random, a drift function as well as a sample & hold function. Programming is handled by two encoders for step and value, each with it's own display. Furthermore there are three modes: Playback, Sequence editing and the settings menu. The created sequences are saved automatically.

The MIDI Delay is a high accuracy programmable MIDI delay.

With a double footswitch or switch triggers you can generate Midi signals of any kind.  The converter has to be taken between a midi sender and a midi receiver, it will be powered up from the incoming midi sender. The generated Midi informations depending on the switch or trigger action will be merged to the forwarded midi flow. Potentially nessessary programming can be made over the midi in connection.
