Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy!

The Erica Synths Black Dual ASR EG is a versatile, full analogue voltage controlled looping envelope generator and low frequency oscillator with manually and voltage controlled shape and rate, designed for use in advanced modular systems.

It has two identical parts, each featuring all typical envelope generator controls and bonus features - the end of the cycle output and bi-polar LFO output. When in loop mode the shortest attack and decay settings turn the module into voltage controlled drone oscillator with adjustable waveform (it will not track 1V/oct, though).

Notes: Multi-function eight-channel LFO, joystick, movement recorder and drone oscillator that packs in lots more functionality than you might expect. A real modulation powerhouse in a compact format.

Supplier's Notes:
Erica Synths Black Joystick2 is 8 channel multi functional CV and sound source - joystick, movement recorder, distinct LFO and drone/noise oscillator. It provides great interaction with the modular system and allows to develop unconventional modulation patterns instantly.

Notes: The Erica Synths Black Low Pass VCF is designed for analogue purists, who take sound design seriously. It's highly stable, 24dB/oct resonant low pass VCF with voltage control over cutoff (two CV inputs, one is with an attenuverter) and resonance. Bonus features are built in post-filter overdrive circuit with user adjustable drive amount and the Black Filter Coupler connector.

When used in combination with the Black High Pass VCF and the Black Filter Coupler, you get a Holy Trinity of VCFs for an ultimate analogue modular system.

Cutoff

This is the main control of the module - manual cutoff frequency adjustment. The incoming CV is added to the cutoff knob position.

Remove the jumper and connect the Erica Synths Black Filter Coupler. 2x5pin ribbon cable is supplied with the Black Filter Coupler module. Use this trimpot to adjust post-filter overdrive to your taste.

Notes: Introducing a four independently buffered input mixer and a buffered output signal splitter, in one module!

Erica Synths Black Mixer/Splitter V2 is an advanced replacement for stackable patchcables.

Everyone who knows a bit more about electronics will point out that stackable patchcables are not a really wise choice for such sensitive things as musical instruments because they mechanically connect electrical signals that at best can cause undesired modulations or even damage the modules.

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, design and usability were prioritised first. Big knobs are assigned to functions that make difference in sound.

Notes: One of the most authentic sounding emulations of the famous Russian synth the Formanta Radio Factory Polivoks in 10HP

Erica Synths Black Polivoks VCF is one of the most authentic sounding emulations of the famous Russian synth the Formanta Radio Factory Polivoks.

The original Russian ICs K140UD12 are used in the sound circuit. Several updates were added to adapt the VCF for contemporary modular synth demands, it has independently buffered inputs, extended Cutoff knob, eliminated clicks when switching filter modes and output stage added to eliminate signal inversion. The result is a much punchier bass sound and very smooth controls.

Notes: The Erica Synths Black Ring-Xfade is an extremely versatile module for sound shaping. It consists of two unconventional ringmodulators/waveshapers, a crossfader that works both for audio and CV and a VCA. Unlike conventional ringmodulator that works only with a signal present on both signal and carrier inputs, the Black Ring-Xfade passes through the signal without alteration, if no carrier is present, but low level signals on the carrier input result in unique waveshaping. Add the crossfader between two ringmodulators (or as a separate unit) topped up with the VCA, and you have an amplitude modulation powerplant in 10HP!

Ring1 CV; Ring2 CV
These are the ringmodulator carrier (CV level) level controls. Unlike conventional ringmodulator, this one passes signal unaltered, if RING CV is turned down. With increasing Ring CV level a slight waveshaping turns into proper ringmodulation.

Xfade
This is a manual Crossfade control. This fades smoothly between signals patched into XFADE IN1 and XFADE IN2. The XFADE CV is added to the knob position.

Coupling
Set the Crossfader mode - AC is optimized for use with the audio signals, DC - for control voltages (but it will work fine with audio, as well).

Ring 1; Ring 2
The green LEDs give visual feedback on signal levels, applied to XFADE IN1 and XFADE IN2 respectively.

Vol CV
Select the VCA CV response. A 0-10V setting is intended for use with the envelope generator, a -5V - +5V setting - for nice tremolos with a LFO.

Xfade IN1; Xfade IN2
These are the Crossfader inputs. They are normalled to the Ringmodulator ouputs, so, if nothing is patched here, you can crossfade between two ringmodulated signals.

Xfade CV
This is the Crossfader CV input. The CV is added to the XFADE knob setting.

VOL CV
This is the VCA CV input. The VCA is post-crossfade - it controls the amplitude of a resulting signal after the crossfader. It will also work with low frequency control voltages applied to the XFADE Ins - nice for designing unconventional modulations.

Ring1 Out; Ring2 Out
These are the ringmodulator outputs.

Xfade Out
This is the Crossfader output and the main output of the module.

Ring2 In; Ring2 CV
These are the second Ringmoduator signal and carrier inputs respectively. These two are normalled to the RING1 inputs, and if no signal is patched here, the duplicate the first Ringmodulator. Interesting trick is to set RING CVs at different levels and crossfade between two ringmodulator signals.

Ring1 IN; Ring1 CV
These are the first Ringmoduator signal and carrier inputs respectively.

Fade L; Fade R
The red LEDs indicate the crossfader position.

Xfade CV LVL
This is a crossfade CV level attenuator. By adjusting it you can control a span of fading between inputs.

Specs:
Audio level 10Vptp
CV level (full span) -5V - +5V
Power consumption +38mA, -32mA
Module width 10HP

Notes: Excellent value here. Analogue filterbanks tend to be pricy affairs but Erica's Resonant FB gives you all that creative control of dynamic equalisation with the convenience of digital control.

Supplier's Notes:
The Graphic Resonant Filterbank (FB) is a ten-band analogue filterbank with digital control over each bands' boost or cut. Each band can be controlled individually via CV or manually, while complex control configurations turn the filterbank into an unconventional multimode filter and even an instrument in its own right when played with various resonance settings. The Expander module (works exclusively with the Graphic Resonant Filterbank and is available separately) provides hands-on adjustment of boost and cut for all bands.

Specifications:

Audio signal amplitude: 10Vptp
Bandpass filter frequencies: 29Hz,61Hz,115Hz,218Hz,411Hz,777Hz, 1,5kHz, 2,8kHz, 5,2kHz,11kHz +-10%

Notes: Not your average mixer. Erica Synths riff on the EMS Synthi-style matrix mixer, bringing it to a desktop format compatible with just about any other gear, including Eurorack. Uniquely creative.

Supplier's Notes:
As Eurorack users may know, it can be challenging to change a patch radically during a performance, therefore diverse performances require large systems or they end up being extremely experimental. But what if you could repatch your system with the push of a single button?

Features:
All analogue signal path
16 buffered, DC coupled inputs
16 independent, buffered, DC coupled outputs
256 connections, each with 3 attenuation levels
Random pattern mode with definable randomization area and density

Notes: Developed in conjunction with Dutch software masters 112dB, Erica's stereo reverb is the best of both worlds: deep DSP power with plenty of hands-on control. Designed for musicality, ideal for synths, drum machines and more.

Supplier's Notes:
A stereo reverb with a unique and musical algorithms developed by 112db, save/recall functions for all parameters, all in sleek aluminum case to aesthetically match our lineup of compact desktop units.

Erica Synths focused on the musical aspect of the effect - extremely long decay tails are possible without losing harmonic integrity and since multiple parameters can be adjusted at once, notes can be played individually and held in chords, pitch-shifted at a whim or used to create massive, ambient textures.

Notes: We wanted to organize patch cables that were hanging on all possible objects in our Lab, therefore we decided to make patch cable holders.

Rigid, 2mm aluminium powder coated cable holders can host over 100 patch cables in perfect order! Two screws for fixing the cable holder are included.

Supplier's Notes:
PERKONS HD-01 is a unique live performance and sound design instrument that tears down the borders between drum machine, synthesizer, and drone instrument.

PERKONS features four sonically versatile hybrid voices (digital sound engine + analogue multimode filter with overdrive) and a sequencer with simultaneous control over all four percussion tracks.

Each voice has 3 sound engine modes, an HP/BP/LP filter and 8 controls for nuanced sound design, including an internal BBD FX send. All voice parameter settings can be saved as KITS. To add dynamics to the performance, parameter automation is implemented and a modulation LFO can be assigned to all parameters.

For a real thunderstorm, integration with external gear is considered - each voice has a dedicated trigger input, individual output, and FX send and return with 6.3mm jack sockets, along with extensive MIDI implementation. All voices are summed and run through a built-in compressor.

Time to ride the skies!

Erica Synths are pleased to see the enjoyment the PERKONS has brought to users worldwide over the past two years! To celebrate its success, they have decided to transform the beast by giving it a new demeanour - a timelessly black finish to match Erica Synths' other instruments and to visually complement the dark aesthetic that has become synonymous with Erica Synths modules and desktop instruments all over the world.

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: Pico EF is Erica Synths' take on envelope follower module in 3hp! Pico EF features a preamp with +40dB gain (enough to boost even guitar and dynamic microphone signals for use in a modular system), envelope output with adjustable attack time and a gate output with adjustable threshold. The Pico EF can be used as a preamp, overdrive unit or for controlling VCFs with audio signal, or to use with external instruments to control your modular system in other creative and experimental applications.

Technical specifications:

Preamp boost: up to +40dB
Audio output level: 10Vptp

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: Pico Mixer is simple 3 channel DC coupled mixer intended to mix audio signals and CV signals in order to obtain complex modulations. Also it may serve as CV and audio attenuator.

Notes: Those, who own Moog Mother 32 know, that it requires -5V - +5V on 1V/oct input to operate in full range, while the eurorack standard is 0V - +10V. So, to control Moog Mother 32 from a eurorack sequencer you need to bias a sequencer output for 5 volts down. And vice versa, Moog Mother 32 sequencer outputs -5V - +5V on 1V/oct output, and, if you wish to control some eurorack VCO from Moog Mother 32, you need to bias it 5 volts up. This is exactly what MSCALE does: it has two sections, upper one adds 5V to the input voltage, other subtracts 5V form the input voltage.

Of course, the module is not limited for use with Moog Mother 32 only. You can use it as a regular eurorack precision voltage scaler.

Features:
Precision scaler to adapt Moog Mother 32 1V/oct to
Moog to eurorack section

Notes: Performance oriented Sample Drum brings you two independent drum sounds or loops with plenty of manual and CV controlled parameters. Samples are stored on the microSD card, and OLED screen makes working with samples instant and easy.

Sample Drum allows you to slice up loops directly in your modular system and rearrange them to taste. For processing, there are tuning functions (including 1 v/octave pitch tracking) and virtual VCAs plus AD envelopes. Thanks to the module's dual-channel concept, two loops can be combined. It is also possible to load one-shot samples instead of entire rhythms, of course. A total of six CV inputs guarantees lively results.

Sample Drum is composed of two identical audio players. WAV files (including cue points) are fed to the module via a micro SD card. Loops can be cut into several sections using the Data, Start and End potentiometers. The resulting slices may be played back in any order imaginable. A tune control allows real-time pitch changes. Additionally, there is a virtual VCA plus AD envelope per slice. - But that's not all! There are three CV inputs per channel, which can be routed to any parameters. It is even possible to play sounds according to the 1 v / octave standard. Results are emitted via one output per player.

Notes: No oscillators, 8 voice polyphony.

The Steampipe is a true physical modelling synthesizer developed in close collaboration with Dutch company 112.dB.

The Steampipe has no conventional oscillators. Instead, it mimics the way sound is created in wind instruments and it is fine-tuned to create a wide range of sounds - everything from wind instruments to strings, pipe organs, crazy effects and beyond. The Steampipe has three major sections - STEAM, PIPE and REVERBERATOR.

The STEAM section can be compared to the lungs and mouth of a musician. The generator creates the flow of air or "steam", the envelope in this section determines the force with which it is blown out. DC/noise is the noise you get when blowing out. DC/Noise on the Steampipe can also be replaced with an external audio source.

The PIPE section can be compared to a flute. In the pipe, the tune is formed. Push (in feedback) bounces the steam like it does in a flute and generates the tone. The delay box subsection changes the flute's tuning and shape.

The REVERBERATOR adds space and ambience to the sound.

The Steampipe is optimized for performance with wind MIDI controllers and it works great with any MIDI keyboard. The overtones the Steampipe produces are very organic and rich and it comes with great-sounding presets. The Steampipe is rather versatile and allows for nuanced sonic exploration, conjuring sonic imagery ranging from from wisps of cloud to fairground band organs, then to industrial horns of the railroad and finally, to massive, otherworldly ambiences.
