Notes: Perfect for adding that final touch to a modular patch, the AJHSynth Finaliser R-EQ module includes seven Mono / Stereo reverb types, along with a four band equaliser and a Sonic Maximiser / Enhancer.

The Reverb, EQ and Maximiser can be used in Mono IN, Mono OUT mode or Mono IN, Stereo OUT modes. The reverb alone can also be used in Stereo IN / Stereo OUT mode too.

The fully analogue four band Equaliser includes three parametric equalisers for Low, Low Mid and High Mid ranges, and the High EQ has switchable shelving of either 2kHz or 5kHz. The Low EQ also includes a shelving mode.

The Maximiser is a fully analogue circuit too, with low and high treatment bands which change the phase and amplitude relationships of the sound to add punch and harmonics and really bring the sound to life in the mix.

The Reverb engine is based on 20 year old DSP technology, harking back to the reverb units which were used extensively on many synth and EDM tracks a couple of decades ago. We have added full control of reverb wet / dry mix, either manually or under CV control.

Notes: Sewastopol is a multifunction Eurorack module designed for easy interfacing of external gear to your modular environment. It can export line and professional level audio, import audio from instruments and electroacoustic transducers, and analyse the incoming audio to generate voltages and triggers to control your modular system.

This is a second, vastly improved revision to the original 2014 Sewastopol, featuring a completely redesigned preamplifier circuit, better ergonomics and various other improvements.

Notes: The FUMANA is an all analog dual filter bank with various control to access dynamically these bands. Each filter bank is composed of an array of 16 independent 48dB/oct bandpass filters. Having two identical filter arrays, allows you to use one of those for spectral analysis (of a modulator signal) and the other for spectral re-synthesis (of the main signal). Each array is sub-grouped in odd and even bands (numbering these increasingly from 1 to 16 from left to right). It is possible to apply different signal to odd and even bands, both for main and/or modulator arrays. This, together with the 16 envelope followers connected to each band of the modulator filterbank, and the 16 VCA connected to each band of the main filterbank, allows the FUMANA to perform a single 16 bands or a dual 8 bands analog spectral transfer.

While the upper section provide access to each main filter's direct output, the lower section has 4 voltage controllable parameters to manage two independent functions for further spectral editing: tilt and parametric scan.

The tilt, as the name suggest, tilts the spectrum, adding and subtracting amplitude to the 16 bands, emphasizing lower or high bands, and attenuating high or lower bands: this is managed only with the green potentiometer.

The parametric scan, instead, works with three parameters: peak/notch, band selector and width. Like in a parametric equalizer, where is possible to set peak/notch gain, frequency and slope, the FUMANA uses three parameters to set which is the centre band to perform this manipulation, then if that band should be emphasized or attenuated, and how this action is extended to nearby bands.

In addition to the 16 bandpass outputs, there are other 4 outputs provided: the all bands output, the all envelope followers output, the odd bands and the even bands output. These two have the options to be inverted in phase with two switches, in order to obtain even more combination when summed together, maybe/also with the "all bands output", using, for example the 333 module.

Since a spectral transfer tool may be used as a "vocoder-like-effect", the FUMANA provides an input for an external noise which may be used for unvoiced (fricative/sibilants) sounds as words containing or starting with s, f, z, ch and other fricative sounds.

Notes: Pluck is a physical modelling synth voice. It uses the Karplus-Strong algorithm to create plucked string sounds. The dampening control sets the size of the string and allows for dramatic timbral shifts.

The decay control changes note length from percussive transients to infinite harp sounds. In addition, four voice polyphony provides complex layered tones; all from a single sound source.

Strum a new chord with Pluck.

Notes: Clep Diaz is a handy and small step CV and LFO generator. In step and random modes, use the encoder to control the number of steps in the sequence; in LFO mode, the encoder controls the amplitude of the wave. Toggle the directionality of the sequence: up, down, or up/down to customize the CVs further. CD also gives CV control over the number of steps in the sequence and an end-of-cycle trigger output. Unipolar and bipolar outputs allow maximal control.

Notes: ***Now featuring Assimil8or Software Version 2.0! Available to download here: http://www.rossum-electro.com/products/assimil8or/

The ASSIMIL8OR is a CV/Gate-controllable sampler with eight independent channels. Each channel is not only its own voice, but also has a separate audio output and a gate/trigger and three CV inputs. Given ever get two sample inputs and main outputs. Thus, Stereo Sampling and playback is possible. Mixed operation of stereo or mono is possible and is limited only by the maximum number of eight channels or parts.

The ASSIMIL8OR works with high-quality 24-bit AD and DA converters. Internally, however, sample and bit rate for lo-fi sound can be lowered, the latter is even CV-controllable. The samples can also be otherwise manipulated in many ways. Thus, the phase of a sample via CV or a different sample can be modulated. Likewise, the loop points can be controlled and the sample can be traversed with CV control (scrubbing), whereby wavetable similar effects could be achieved. The following parameters can be addressed via the gate / trigger and CV inputs:

- Pitch
- Level
- Bit Depth
- Phase Modulation
- Pan
- Scrub
- Sample Start
- Sample Length
- Loop Start
- Loop Length
- Release Decay

Samples and presets are stored on an SD card, which is easily accessible plugged into the module front.

Notes: Erica Pico RND is combined LFO/random source module.

It generates sine LFO waves, white noise, S&H CV and some interesting stuff - random triggers and pulse wave with random duty circle; basically, everything, you need, to bring some uncertainty in your modular setup.

The Pico RND comes equipped with five outputs, they emit the following signals:

- Sine waves
- Pulse waves with varying width
- Random triggers
- Sample and hold material
- White noise

The speed of LFO and S&H circuit can be edited using the module's potentiometer (Range: 0.1 Hz to 20 Hz). For synchronizing the Pico RND with other gear, a clock input was implemented.

Notes: Pico DSP is a small brother of the popular stereo effects processor Black Hole DSP. It contains eight algorithms, in detail four delays, two types of reverb, Leslie speaker emulation and an Overdrive/Bitcrusher. Each effect is editable in two parameters. One of them can be modulated using the CV input. Pico DSP features clear, high-resolution sound. Alongside the established standards, it is also possible to generate lots of freaky special effects.

Notes: ADSR is a four stage linear envelope with two expressive ranges. Each stage can be modified independently allowing for the creation of complex, multi-segment envelopes. Great for modulating filters, VCAs, and oscillators.

Notes: Div is a 2 channel, voltage controlled clock divider and multiplier. Incoming clock signals can be multiplied or divided by a factor of 16 with a multitude of values in between.

CV inputs provide external control of the current clock rate, allowing for the creation of dynamic rhythms from a single clock signal.

Notes: Mix is a 4 channel mixer that is great for audio or control voltage signals. Up to four inputs can be combined to a single output each with its own level control.

Notes: Mult is a 2 input, 6 output signal splitter. Channel 1 is normalled to channel 2 when no cable is present, allowing the user to split an input signal six ways, or two input signals with three outputs each.

Notes: The 2hp VCA is a dual, linear VCA. It uses the renowned 2164 SSM architecture, giving it extremely low distortion and high quality audio outputs. With a CV input attenuator, and DC-coupled inputs this is your new go-to module for voltage controlled amplification of audio or CV.

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

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

Notes: 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: Clk is a voltage controlled clock generator with all the features a master clock needs. It has an extremely wide range from ten seconds between pulses well into audio rate. In addition, the pause button and CV input provide an expressive feature that is all too often missing in a modular setup. Stop using LFOs or other modulation sources for your master clock, and let Clk do what it's best at.

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: Great for generating random voltages from white noise, arpeggios from sawtooth waves, and downsampling audio signals.

Notes: Arp is a gate-driven arpeggiator with a multitude of chord types and playback modes. Voltage control over both root note and chord type allow for sequencing any combination of chords in any key imaginable.

With the rate of the arpeggio and reset capability in your own hands, you're free to create dynamic rhythmic melodies from your favourite chords. Take your tonality for a ride with Arp.

Notes: The Meng Qi DPLPG is a Dual Passive 1-pole vactrol based Low Pass Gate/VCA in modest 2 HP. No power is required as the design is completely passive.

Handpicked components ensure that the modules will be musical.

Feed it a trigger and enjoy the natural smooth decay of a vactrol.

Notes: Module A-151 (Quad Sequential Switch) is like an electronic four-position rotary switch.

It includes trigger and reset inputs, four in/outputs, and a common out/input. Each time a pulse is received at the trigger input socket, the common out/input is connected to the next in/output. After the fourth in/output, the next trigger makes it step back to the first again, and so on. A positive pulse at the reset input switches the out/input immediately back to the first in/output. Voltages in the range -8V...+8V at the O/I resp. I/O sockets can be processed by the module.

Four LED's indicate the active in/output (ie. the one that is connected to the out/input at any particular time).

Notes: Record. Mangle. Destroy.

Nebulae is a granular sampler and DSP platform. Its phase vocoder audio engine provides elastic audio, which can be time stretched, granularized, and mangled to no end. With independent control over pitch and speed, and granular controls such as overlap, window, and density, finding new sonic territory is only a knob turn away. Nebulae can use live audio input, a recorded buffer, or audio files as the source material for its powerful audio manipulations. The live input buffer can record up to five minutes of stereo audio at 48kHz, 24 bit. In addition, up to 75 MB of stereo audio can be loaded simultaneously through the USB port. No naming convention or special formatting necessary; just plug and play.

Nebulae lives a double life as an open source DSP platform with an extensive library of off the shelf alternate instruments. You can turn the module into a lush reverb, spectral delay, or tape-style looper simply by loading a new file onto the flash drive. Do you want to tweak one aspect of an existing instrument, even the default functionality? No problem. No prior coding knowledge is necessary to tweak and refine existing firmware to your liking or start with one of our templates. Alternate firmware files can be written with Pure Data, Csound, SuperCollider, and even bare-bones C programs.

Notes: Tetrapad is a versatile, multi-dimensional, touch-sensitive control surface for Eurorack. Each of its four pads use force sensing resistors to respond to both the vertical position of your finger and its pressure. Four push encoders and a shift function give you even more tactile control over your modular system.

Tetrapad operates in numerous modes - each of which configures the module to perform a specific control task. Through these modes, Tetrapad can emulate a bank of faders; a voltage storage device; a finger drumming surface; a chord generator; an 8-key keyboard; four independent LFOs; or an 8-switch panel. The chosen mode determines what type of signal (CV, note, trigger, gate, etc.) is sent from each of Tetrapad's eight independent outputs, while its multitude of multi-coloured LEDs keep you informed of exactly what's happening within each mode.

Tetrapad automatically remembers how you've configured each of its modes and retains these settings when powered off. By default, Tetrapad automatically saves these settings every minute, or whenever you change modes. This makes Tetrapad ideal for live performance, since you know it will always power up with your configurations intact.

Notes: Erica Synths MIDI to Trigger module lets you control your drum modules and trigger events on your modular from any MIDI sequencer!

If you want to use a MIDI sequencer to trigger events on your modular synthesizer (e.g. using the hexinverter.net Mutant drums range or Tiptop Audio classical drum modules or envelope generators to control VCAs), Erica Synths MIDI to Trigger module is just what you need, it converts ANY MIDI notes to eight 10ms Trigger signals.

When designing the module, Erica Synths put usability as priority; it will take you seconds to program the module. It works with any MIDI sequencer & controller so there is no need to change MIDI controller settings, instead, you reprogram the module.

Notes: Mimetic Digitalis is a 10HP step sequencer optimized for live use. MD includes four individually editable CV outputs and a trigger out. Each step can be manually programmed or use MD to live record CV sequences using the encoder. The zero button mutes the CV at a step and shred randomizes the voltage. Save and load up to 16 patterns. Edit a pattern and use undo to return to the unedited version.

Notes: This new device is a powerful new CV controlled effects unit for your electronic music setup and pairs extremely well with the KOMA Field Kit.

- Looper
- Frequency Shifter
- Sample Rate Reducer/Bitcrusher
- Digital Delay
- Analogue Spring Reverb
- 4 Channel VCA Mixer
- 4 Step Mini Sequencer
- Envelope Generator

All of this, combined with the new 4 Channel CV Interface which allows you to route four CV signals throughout the device, means an incredible control over sound and timbre and a great addition to your mobile performance rig.

The Field Kit FX is built up from 7 separate functional blocks all focused on mangling and changing incoming audio and CV signals. They are designed to operate together as a coherent addition to our Field Kit Electroacoustic Workstation or alternatively together with other pieces of music electronics with the ability to use control voltage signals.

Notes: Module A-103 is a voltage controlled low pass filter with 18dB/octave slope. The circuit is based on a modified transistor ladder (Moog ladder) and is a reproduction of the legendary TB303 filter.

As for the rest the A-103 is identical to the A-120 Moog low pass filter (same controls, inputs/outputs) only the filter sound is different.

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: The WAV Recorder from 4ms Company is a high fidelity, two-channel stereo audio recorder with basic playback features. Accepting a wide range of input signals, from line-level to modular-level, the WAV Recorder stores audio onto a microSD card in lossless .wav format up to 96kHz/24-bit. The trigger jack can be used for capturing rhythmic loops or synchronizing multiple WAV Recorder modules for multi-track recording. In Playback mode, the trigger jack or button plays the most recent recording. A simple file/folder navigation system can be used to browse the folders on the card for playing back .wav files. A Gain knob allows for up to +20dB of boost, and an LED Signal Meter indicates clipping and the signal level.

Notes: Tiptop Audio's Z-DSP is a cartridge-based open source digital sound processing and effects generating platform for your modular synthesizer. Lush audio processing, greater stereo depth and a unique set of digital synthesis is what the Z-DSP is all about.

The Z-DSP has a stereo digital sound processor with 24-bit sampling, 15kHz of bandwidth, voltage-controlled parameters of stereo feedback, program switching, DSP parameters, equal power crossfading dry/wet mixing, as well as sequential program control switching and a clear display - all in Eurorack format. A dedicated clocking input for the DSP chip does wonders to passing sound by bending the algorithms in an unexpected way, a hardware technique computer plugins can't do and is unique to the Z-DSP.

In a recent update, the Z-DSP (NS) got an all new design of its analogue circuitry, contributing to a lower noise signal path, clearer sound of the entire frequency range, lower distortion and better immunity to noise emitted by other modules sharing the same power supply. A new analogue dry/wet circuit has been implemented to remove the 3db gain drop when the mix knob passes through the centre of the dial making the use of this function more practical in a live application. A reverse polarity protection has been added as well. The new front-panel matches Tiptop's colourful design, and a single printed circuit board and surface mount technology improve reliability during production and use. The powerful Z-DSP engine remains the same as the original Z-DSP module and all cards are compatible across both versions.

An assortment of interchangeable cards, programmed by Tiptop Audio and specialists like Valhalla DSP, provide a wide range of boutique effects algorithms such as Halls of Valhalla, Time Fabric, Clocked Delays and Grain De Folie. Tiptop Audio also offers blank Z-DSP cartridges and a development tool called NumberZ for developers, students and power users who want to design their own effects and cards with the FV-1 DSP chip programming language. Blank cards can be loaded using programs that are freely available for non-commercial use and can be found in the modular community through online forums. With each card swap, the Z-DSP takes on new effect algorithms, changing like a digital chameleon and bringing colourful digital effects processing to your Eurorack setup.

The Z-DSP comes included with 2 cards: Halls of Valhalla and Dragonfly Delay MKII.

Notes: The 'HPO' is an affordable super slim and skiff friendly no frills stereo headphone driver output for your modular synthesiser. Includes a volume control and ability to double up a mono signal into stereo. A great use for that left over 2hp in a skiff or larger system.

Give loved ones, friends and acquaintances a break from your musical 'genius', the HPO offers a solitary cell for focused creativity impregnable from undeserving non-believers.

Notes: Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

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

The output voltage range for each envelope is 0 - 10V. The time range of Attack/Decay/Release is about 1ms to 30s.

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

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

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

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

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR. Changing the positions of the mentioned jumpers allows to modify the factory settings.

Notes: The WaveSwarm is a waveform animator and all analogue dual channel device.

Each channel simulates up to six VCO's beating in unison with a different beat frequency between each animation. The fixed beat frequencies are generated by twelve onboard LFO's, and the front panel pots control the level of each of the six animators, along with the level of the dry signal to the final mix. In addition to independent channel inputs and outputs it also has an A+B output, which sums the outputs of the two channels, creating an effect similar to twelve VCO's in unison! This is possible because channel B uses slightly different beat frequencies to channel A, they are not identical.

The input waveform can be saw, triangle, sine or wavetable/complex waveforms, in fact most waveforms with the exception of square or PWM waves will give some form of animation.

A soft clip circuit is built in so that at higher signal levels the signal magnitude is limited by rounding the top and bottom of the waveforms, thus slightly softening the sound. There are soft clip LED indicators for both channels.

It can produce huge, fat drones or supersaw type waveforms from a single sawtooth or triangle wave input.

Notes: Module A-115 is a four-way frequency divider. The frequency of a signal at the input is halved (half frequency = first sub-octave), quartered (1/4 frequency = second sub-octave), and so on. In this way, the DIVIDER produces four sub-octaves (F/2 down to F/16).

At the output, the A-115 produces a summed mix of the original and the four sub-octaves. There are attenuators to control the amount (i.e. Amplitude) of the original signal and each of the sub-octaves.

Bear in mind that the sub-octaves output by the A-115 are all true square waves. At the output there are always four square waves and the original signal available.

Notes: Module A-199 is a spring reverb module. The reverb effect is electronically simulated by means of 3 spiral springs. Spring reverb systems have a very characteristic sound that is based on the (insufficient) mechanical properties of the springs like signal delays, audio resonances, limited frequency range, acoustic feedback behaviour, sensitivity to mechanical shocks and others.

The 3-spring system used in the A-199 ensures a "dense" reverb because of the different properties of the three springs.

The A-199 implies some special features that are not self-evident for spring reverb units:

The reverb signal can be fed back to the input using the Feedback control. Even self-oscillation of the springs similar to the self-oscillation of filters is available. The feedback loop can lead even via external modules like VCA, VCF, phaser, frequency shifter, vocoder, distortion/waveshaper, ring modulator and others. In this case the reverb output of the A-199 is connected to the input of the external module(s) and the output of the external module(s) is fed back to the Ext. Feedback In socket of the A-199. This socket contains a switch that interrupts the internal feedback loop as soon as a plug is inserted.

Another feature is the Emphasis control. This enables the adjustment of the accentuation of middle frequencies (around ~ 2kHz).

With the Mix control the relation between original and reverb signal appearing at the mix output is adjusted.

Using all these features very extreme and unusual effects can be generated with the A-199.

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 Synths Drum Mixer Lite is compact version of Drum Mixer. It features extended headroom and a dedicated drum compressor of unique design keeps each drum sound clearly distinguishable and add power to the final mix. Bonus feature - effects send output allows to apply external effects to the signals on the first three inputs. LEDs next to each input give visual feedback on the signal level.

Features:
6 inputs
Built in vactrol based drum compressor with Amount and Decay control
Three inputs assignable to main or aux send outputs
Main and Aux Send outputs
Signal level indicator LEDs

Mixer gain: -+6dB
Power consumption: 59mA@+12V, 36mA@-12V
Module width: 10HP
Module depth: 35 mm

Notes: Erica Synths Bassline is fully analogue synth voice module for ultimate basslines and leads.

It features AS3340 VCO with three waveforms, a filter inspired by Erica Synths Acidbox and unique features - transistor based suboscillator and two BBD lines that emulate VCO detune creating a sound of massive polysynth from one oscillator.

Accent provides more expression to the bassline, by adding volume and opening the VCF slightly.

Notes: The Rene music synthesizer module is a powerful three-dimensional prism of composition. It is the world's only 3D Cartesian Music Sequencer. Named for the French philosopher & mathematician Rene Descartes, it uses the Cartesian coordinate system to unlock the analogue step sequencer from the shackles of linearity. The original Rene was a one-channel, two-dimensional Cartesian sequencer with limited memory, this new Rene is a three-channel, three-dimensional Cartesian sequencer with memory for up to 64 complete States. Considering the multiple channels and FUN programming options per multiple axis, Rene has become an n-dimensional matrix or tesseract of synthesizer sequencing.

Notes: MMF is an analogue, multimode filter with a 12dB per octave slope. Its sonic character swings all the way from classic low pass to squelchy acid lines. Simultaneous outputs of low pass, high pass, and band pass filter types are provided allowing for many variations of the input signal. Whether you're looking for smooth and creamy, or resonant and wild, MMF can go there.

Notes: Erica Synths Black Hole DSP 2, an updated version of Black Hole DSP features 24 custom effects, designed in close co-operation of Erica Synths team rider KODEK and creator of SpinCAD software Gary Worsham. Each effect has 3 manually and CV controllable parameters, manual and CV control over sampling frequency for spanning from 48kHz to really Lo-Fi crunchy sound and full analogue dry/wet control. All effect parameter settings can be saved to the memory and instantly recalled with the effect, which makes Black Hole DSP II ideal for live performances.

Notes: Erica Synths Clap is developed together with French company e-licktronic and it's our take on analogue clap circuits adapted for modular systems. Sharp, punchy sound, Accent & CV control over Tone make it distinctively expressive in studio and live performances.

Notes: Erica Synths Snare Drum is developed in collaboration with the French company e-licktronick and it's our take on analogue snare drum circuits adapted for modular systems. Sharp, punchy sounds, Accent & CV control over key parameters of the module make it distinctively expressive in studio and live performances.

Notes: To add some space to your compositions and nuances in sound design Erica Synths Dual FX module brings you two identical sections of 8 custom effects with two adjustable and CV controllable parameters.
Dual FX combines two Spin FV-1 chips in one module, each filled with eight custom effect programs with two adjustable and CV controlled parameters per effect and analogue dry/wet circuit. All parameter settings can be saved with the effect and recalled instantly during the performance. Also the output of the first FX section is normalised to the second input so creating huge layers of effects is easy.

FX:

Mono delay
Stereo delay
Hi-pass delay
Big reverb
Saturated reverb
Stalker reverb
Ripper
Dual pitch shifter

Technical specs:

Audio output level: -5...+5V

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.
