Notes: Erica Synths Acidbox III brings you the core of the famous Polivoks VCF in stereo version with a unique audio signal overdrive circuit, built in LFO and envelope follower in a compact, full aluminium case.

The Acidbox III has adjustable input gain, therefore it works with various sound sources - guitars, units with line level signals (synthesizers, grooveboxes, etc.) and modular synths. Configurable control input allows you to connect a bypass footswitch, expression pedal, external cut-off control voltage source and LFO synchronization trigger. This makes the Acidbox an ideal companion in almost every production or live performance setup.

Notes: ***B-STOCK: Item refurbished, repaired and in perfect working order.***

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: Premium analogue delay from Erica's flagship Black Series range. Two bucket brigade device delay lines work simultaneously with smooth crossfading and tons of voltage control. Lovely.

Supplier's Notes:
Erica Black Series include high-end, unique functionality and superior quality modules. Only the best, highest quality components are used, all inputs and outputs are protected against undesired overvoltage. When designing Black Series, put design and usability superior. Big knobs are assigned to functions that make difference in sound. Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy!

The Erica Synths Black BBD is one of kind analogue delay module. It features two BBD lines: short, 1024 stage and long, 4096 stage, that work simultaneously and you can smoothly fade between those two, thus creating distinct multitap effect.

Furthermore, an advanced BBD clock noise cancellation circuit is implemented that reduces unwanted BBD noise without filtering higher frequencies of audio signal. Most of parameters are voltage controlled, which allows to integrate the module in complex modular setups.

Time

This is delay time manual control.

Because of BBD clock suspension circuit, delay time can be pushed in extremely long regions, however in that case BBD clock noise may appear. The Time CV is added to the knob setting.

In level

This is the input attenuator switch. Select among full amplitude, half amplitude and audio off.

BBD mode

This control smoothly fades between short and long delays. Any setting in-between will result in distinct multitap delay effect.

LFO rate

Adjust the internal modulation LFO rate. The internal LFO controls delay time, and it's automatically disengaged, when an external modulation signal is connected. The LED gives visual feedback on the LFO rate.

LFO shape

Select the LFO shape. Three shapes are available - triangle, square and in-between shape - mix of triangle and square.

Input

This is the audio input of the module. This is manual Dry/Wet mix. The MIX CV is added to the knob setting.

Colour

Even though the module has BBD clock suspension circuit, the colour switch provides extra lowpass filtering of the signal. At top setting no filtering is applied, at lower settings increasing filtering is present.

Feedback

This is the delay feedback manual control. In extreme clockwise settings the module goes into self-oscillation, and by adjusting delay time and BBD mode settings, the module becomes a drone machine. The FBK CV is added to the knob setting.

CV level

This is the Time CV level attenuator. If nothing is patched into TIME CV socket, it controls the internal LFO amplitude.

WET out

This is the WET signal output of the module - use it for advanced patches.

Out

This is the main output of the module.

Time CV; FBK CV; Mix CV;
These are CV inputs for Time, Feedback and Dry/Wet mix.

DELAY OUT
CV ATTENUATORS
These are CV attenuators for attack, sustain and release stages

SUSTAIN
Set the sustain level of the envelope

GATE DEL
Set the gate delay time

TRIGG
You can retrigger the envelope at any stage by applying trigger signal here. The trigger alone initiates an AD envelope instead of ADSR

DELAY OUT
This is the gate delay output. The gate delay section can be used independently to control other modules in your modular setup

D GATE
If you wish to use gate delay functionality, patch the gate signal here

BP OUT
This is the bipolar output - the CV here is centered against 0V and this output serves as an LFO

EG OUT
This is the envelope generator output

M. GATE
This is the manual gate button. A built in LED gives a visual reference of the output voltage

RELEASE
Set the release time of the envelope

DECAY
Set the decay time of the envelope

LOOP
This is a LOOP switch. When it's ON, the envelope generator outputs a signal for which the rise time is defined by the Attack setting and the fall time is defined by the Release knob setting.

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.

Drive

For extreme results, flip the drive switch on! This will apply post-filter drive. You can preset drive level to your taste by adjusting a trimpot close to the switch on the back side of the module.

Reso CV In

This is the resonance CV input.

In Level

Adjust the audio signal level.

Resonance

Adjust the resonance level manually. On settings over 1PM the filter will start to self-oscillate. The incoming CV is added to the resonance knob position.

CV1 Level

This is cutoff CV attenuverter. Adjust the CV level to your taste!

ResoCV Level

Adjust the resonance CV level to your taste.

CV1; CV2
These are the cutoff CV inputs. The CV1 level is adjustable by CV1 LEVEL attenuverter knob, CV2 is applied to the cutoff without attenuation.

The Black Low Pass VCF has a hidden feature - the Black Filter Coupler connector. The Erica Synths Black Filter Coupler is a satellite module for the Black High Pass and the Black Low Pass VCFs, and it adds versatile Bandpass and Band Reject filter functionality to your modular system.

Please note, that the Black Filter Coupler works only with Erica Synths modules and you need both Black High Pass and Low Pass VCFs.

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. Together the Erica Black series are a range of modules that make an entire synthesizer.

Mixer gain: 1
Power consumption : +8mA, -8mA
Module width: 6HP
Module depth: 25mm

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

Supplier's Notes:
The Echolocator is a hands-on precision tool that lets you take manual and very musical control over small nuances. Like a bat navigating its environment in the dark, you can feel your way through your live performances and shape the delay response and character on the fly. Featuring 12 parameters for detailed sound design, save/recall functions for all parameters, MIDI control over all parameters and a sleek aluminium case to match our lineup of compact desktop units, the Echolocator will let your setup take flight in any live show, studio or sonic experiment.

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: This Expander module provides hands-on adjustment over all bands' boost and cut without the need to select bands via pushbuttons on the Graphic Resonant Filterbank module. This makes sound design with the Graphic Resonant Filterbank much easier.

NB! The Expander works exclusively with the Graphic Resonant Filterbank!

Notes: Better known for analogue modules, it turns out Erica Synths are pretty damn good at digital too. Draw your own waveforms, build wavetables, tweak in real time and get freaky. Killer VCO.

Supplier's notes:
Erica Synths Graphic VCO allows you to draw your own waveforms, arrange them in wavetables and wavetable banks, morph between two selected waves and alter the resulting wave in advanced ways (FXes) - apply FM, phase distortion, ring modulation, wavefold/wavewrap, bitcrush.

Waves, wavetables, FXes and other settings can be saved and recalled from the memory instantly. The module has two outputs - the main output and the output with configurable suboscillator.

NB! To have the module functionality up to date, we recommend you to check the Erica Synths home pageor our social media from time to timefor announcements about firmware updates for the Graphic VCO. You can update the firmware of the module via miniUSB cable. More detailed instructions of the firmware update can be found in the User Manual.

The sound is clean, modern, punchy and detailed thanks to the unit running at 96kHz - quite different to some low bit-rate wavetable oscillators on the market. Wavetable interpolation is smooth as butter and with the built-in effects you can dirty things up in many different ways. The module scores highly on the sound front. The Graphic VCO is a very capable oscillator module with excellent sound quality and a lot of features that could make it the right choice, especially if live performance is your thing. - Sound On Sound
The bottom line is that the Graphic VCO is a joy to use. It's a module that's unashamedly digital, yet unmistakably eurorack. I think Erica showed a great deal of careful judgement and restraint in the design of this module. It would have been easy to have made it bloated and cumbersome trying to cram as many features as possible into it, but they kept it fairly simple which keeps the module fun and immediate in use. It's capable of a huge tonal palette ranging from beautiful to brutal that is bound to fit in with a lot of different styles and systems. - Ask Audio
The ability to draw and then effortlessly jump between different custom digital waveforms in this way feels unique on the Eurorack stage, and allows for a wide range of tones and transitions between them. - Orb Mag

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
254 pattern memory
Pattern change via MIDI program change messages
32 3,5mm jack sockets
4 6,3mm jack sockets
The Erica Synths Matrix Mixer is a 16-input, 16-output desktop patch matrix - it can route and mix signals with high precision, create buffered multiples and random patches. It can also interface external instruments with your Eurorack system, and it's not limited to Eurorack!

You can use the Matrix Mixer with semi-modular synthesizers, as well as through adapter cards with the EMS Synthi and Buchla Music Easel. Thanks to simple patch changes via panel buttons or MIDI program change messages, the Matrix Mixer will be particularly useful in performances that combine Eurorack and other performance instruments, such as drums, guitars, wind instruments, etc. Make your modular performance stand out and enjoy the Matrix Mixer!

Technical specifications:
Audio level: 10V ptp
Attenuation level: 1, 0.7, 0.3
Power supply: 12VDC (a universal AC/DC converter included)
Size of the instrument: 225 x 226 x 44mm
Net mass: 1.25kg

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.

Notes: Erica's superb Perkons returns with a stealthy new black paint job. Four hybrid voices each with a range of different sound engine modes, paired with analogue filters, overdrive and a superb sequencer.

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.

Notes: The brilliant Perkons drum machine comes to Eurorack. A single hybrid drum voice with digital sound engine and analogue filter/overdrive, the Perkons Voice is flexible and supremely powerful.

Supplier's Notes:
Erica Synths Perkons Voice is a eurorack incarnation of the percussion voices from the PERKONS HD-01 Drum machine. Like on the drum machine, the module has hybrid architecture, featuring a digital sound engine followed by an analogue multimode filter and overdrive. Users can select among 13 sound generation algorithms and save up to 99 presets that can be recalled easily. Tune and Patch CV inputs are configurable for various CV settings and are tuned to 1V/oct. Module also features a 4-voice poly overlap mode and samples on the "Rompler" engine can be easily replaced.

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
Eurorack to Moog section
High precision, high temperature stability
Skiff friendly, compact design
