ADDAC System - 105 4 Voice Cluster

available

Following our ADDAC103 T-Networks this new module is inspired by its simplicity. This is a 4 voice Square Oscillator with VCA, FM switch and a slew decay for the incoming Trigger IN. All voices are then sent through a Multimode Filter.Each voice has its own VCA input where any input is accepted (Trigger, Gate, CV). The [DECAY] controls the slew decay applied to the incoming signal, if [DECAY] is fully anti-clockwise then it works as a Mute. The [FM ON] switches activate/deactivate the FM input coming from the previous voice: Voice 1 FM comes from voice 4, voice 2 FM comes from voice 1, and so on, so you can FM all of them in a FM loop.All 4 voices are summed and sent through a filter with controls over [CUTOFF] with an Attenuverter for the CV input and [RESONANCE]. Three filter outputs are provided [LOWPASS], [BANDPASS] and [HIGHPASS]The [EXTERNAL IN] input can be routed through a jumper on the back of the module allowing the incoming signal to go to:1. the filter input for processing an external audio source;2. all of the 4 voices Frequency control allowing for some experimental CV control over pitch of all 4 voices at the same time (due to the specificities of the circuit and to keep the module at a low price these inputs are not calibrated to 1v/octave).DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 107 Acid Source

available

We started this module with the idea of developing a complex drum source. However, somewhere along the process we noticed how much better it performed as a synth voice and simply embraced this lucky accident.It features a VCO with a [FREQUENCY] and [FINE TUNE] knob plus a dedicated CV Input and Attenuator knob (tunable over 4 octaves). The VCO waveform output is achieved by selecting either a Triangle or Saw through a switch. The selected waveform can then be mixed/balanced against the square wave. The resulting mix is then sent to the Filter.The Filter features a [CUTOFF] and [RESO] resonance knob plus a Cutoff CV Input and Attenuverter knob.A 3 position switch is used to select the filter type: Highpass, Bandpass or Lowpass. The resulting output is then sent to the VCA.The VCA features an Input with [INPUT GAIN] knob which at maximum can amplify the incoming signal by a factor of 2.This is a very important control, it accepts any signal Trigger, Gate or CV. Whatever input is plugged in the signal is then fed through an AD with a very short attack and controllable decay through the [VCA DECAY] knob plus the CV Input and Attenuverter knob. The resulting slewed signal is then used to control the VCA gain. This signal is also sent to the CV OUTPUT as well as the LED monitor.The Accent input adds to the Input signal creating a different amplitude output. The CV OUTPUT is normalled to the Frequency and Cutoff inputs.DIY-Kit-Type:SMD-Kit-2. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module.

ADDAC System - 604 Dual Filter

available

While developing our ADDAC105 4 Voice Cluster module we made a new multimode filter to place after the summing mix stage. We were so pleased with its sound that decided to release it as a dedicated filter.To make it more interesting we duplicated its circuitry to be able to use it in a stereo signal path.To make it more versatile we added a switch to set the working mode from Stereo to Dual Mono where both filters can be used independently.In Stereo Mode the Left Cutoff is used to control the Right Cutoff.In this case the Right Cutoff Knob and CV Input are simply bypassed and will have no impact on the Right Channel operation.This allows immediate sync of both filter frequencies when the Stereo position is engaged.Optionally there’s a jumper in it’s back that, when placed, connects the Right Controls back to the Right CV control allowing the possibility to control the offset of the Right Channel Cutoff.Resonance is independent on both Modes and still has to be set manually to match both channels.Both the Audio and CV inputs are normalled from the Left into the Right channels.As standard plugging any input to the Right channels removes this connection.DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 605 Spectral Tilt

available

The TILT EQ concept was first introduced in the 1970's by Quad Ltd, featured on the company’s model 34 preamplifier. The tilt control tilts the frequency spectrum of the audio signal by simultaneously boosting the treble and cutting the bass frequencies, or vice versa, making it a simple to use but powerful EQ.As stated by Quad Ltd, it was designed to produce a very gradual change in balance across the musical spectrum without changing the overall subjective level. This gradual fall from Bass to Treble, or vice versa, means there’s no sudden change and hence no ‘coloration’ added to the sound, the sound will remain entirely natural but with a slight added bottom or high end. In practice, it rotates most of the audio-range frequency response around a 1kHz axis, so as to change the overall balance of the sound from warm to cool without affecting either the apparent volume or the "color" of the sound.Here we introduce this idea into the modular world in a stereo configuration. CV input with attenuverter was added for the Tilt control as well as a Spectral Motion switch that allows stereo spectral matching or inverted spectrum use of the Tilt control: Left = Right matches both channels direction, i.e. when left channel is tilted to the low end the right channel will also be tilted to the low end. Left ≠ Right inverts the Right channel spectrum, i.e. when left channel is tilted to the low end the right channel will be inversally tilted to the high end, or vice-versa. This possibility is extremely interesting when applied as a stereo effect, in other words, a spectral EQ panner.DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module.

AtoVproject - cDVCA (Black)

available

cDVCA or class-D VCA is a new kind of VCA based on an entirely novel concept that is inspired from class-D amplification technology. This is not a transparent VCA and brings a lot of character to the sound.The first VCA that tracks 1V/octConcept: The input signal is turned into an ultrasonic PWM signal (~34kHz). The PWM is scaled to the desired amplitude and then filtered back down to the original signal.The twist: The PWM frequency can be lowered down into the audio spectrum and the frequency can be controlled via its 1V/oct input allowing for crazy waveshaping that tracks your melodies.The drive controls an innovative clipping method that does not rely on overdriving any circuitry and therefore results in distortions with a very defined character.The signal then goes into a 1 pole VCF/tone circuit that allows to keep things under some amount of control as the harmonics produced by this module can be very aggressive.With no input the module generates a simple square wave and therefore can be used a simple synth voice (VCO→VCA-VCF)DIY-Kit-Type:SMD-Kit-1.

Befaco - Hexmix

only 1 left

Hexmix System is a six channel performance mixer specially designed for Eurorack.The system has two separate modules, the core of the mixer: Hexmix that has six channels with three band EQ, mute, pan and EQ section on the master, and Hexpander that add three auxiliar sends per channel, PFL, individual outs and balanced output.The mixer has a strong inspiration in classical DJ mixers, providing sharp EQ’s for enhanced performance, auxilliar send for effects and individual outputs to record your performance per channel.The system is designed to be placed in 6U, instead of the traditional 3U paradigm in Eurorack. So we will have every feature for each channel vertically as a conventional tabletop mixing deck.Six channel mixer with three band EQ, vactrol mutes, pan and volume control per channel.Inputs for every channel are located at left side of Hexmix. Each jack is normalized to a VCA Expander connection in the back, so if you have a Hexmix VCA , you will have the output of each VCA to every input. connecting a jack in any input will disconnect whatever is coming from VCA.Gain is set to unity, so it will act as an attenuator of the input signal. Mutes are clickless, as they are vactrol based. This circuit provide some decay on the mutes, rather than a sharp cut.Swithces have latch position and momentary ones to unmute the channel, providing some really nice performative capabilities.EQs are quite sharp (12dB) inspired in classic dj mixers to aggresively cut selected frequencies.Master section has it’s own EQ and volume control for the mix of all channels. Master EQ is softer than individual channel’s (6dB) and it’s meant to provide control over the final mix.It’s possible to change output level from line to synth with a switch located in the back.This will be pretty useful when used in combination with hexpander, that provides a balanced out at line level. Like this its possible to have a mix at synth level to re-route the master signal while having an output to PAFeatures:• Six Channel Performance Mixer• Three Band EQ per channel inspired in classical DJ mixers• Vactrol based mutes with momentary action.• Pan and Volume control• VCA Expander connection to plug every channel of an Hexmix VCA directly.• Selectable Line or Modular output level.DIY-Kit-Type:THT-Kit-1.

Befaco / Divkid - Stereo Strip

available

Stereo Strip takes the idea of a channel strip and makes it modular. We hope that by bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters that you will find new, creative ways to use it in your patches!It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.This module is designed in collaboration with Ben Wilson aka Divkid.Features:• 3 band EQ• Panning (manual and voltage controlled)• VCA level control (manual or voltage controlled)• 3 way performance muting (on-off-momentary)• Soft clipping limiter (distortion!)• Line level input and/or output adjustmentDIY-Kit-Type:SMD-Kit-1.

SALLEN KEY is our tribute of the legendary MS-20 filter. We've tried our best to honor this unique and iconic filter.It’s composed of a 2 Poles Low Pass and a 1 Pole High Pass. Unlike the original we added a crossfader allowing you to blend the Low Pass and High Pass filters to create complex filtering.What makes this filter special is its non linear feedback path. This design avoids the filter to clipping when self-oscillating, but also gives its unique color. We’ve choose to integrate LED’s instead of diodes. It not only slightly changes the color of the resonance, but also gives a nice feedback information about the drive of the resonance path.Since SALLEN KEY can self-oscillate it can be use as sound source. Tracking is accurate across 6 octaves.DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module.

Chair Audio - Ilse

available

Ilse is an elegantly minimal, yet fully functional synthesizer voice in a compact 10 HP Eurorack module. The only thing you need to let it meow is a CV source to trigger its 1V/Oct frequency input (or a MIDI to CV converter and a MIDI sequencer) . Because it has a low part count it is ideal for Eurorack beginners or entry-level DIY projects.Ilse is named after a cat, living in the legendary “Villa” in Weimar, Germany. The “Villa” was a place where a community lived and came together. Many underground concerts and parties took place here before the house got sold, renovated, and the mayor moved in. We created the graphics on the aluminum face-plate in her memory. Ilse (the synth) makes great acid sounds, so it was only logical to illustrate a cat tripping. Turn the knobs to make her look around or roll her eyes.Ilse is designed to be affordable, easy to build, yet flexible, and feature rich. It is a synthesizer voice for your Eurorack, but can even be driven without a rack using two 9V batteries (not included).Ilse is fully open source (KiCad schematic and layout is available in a git repository) and inspired by Syntherjack’s single-chip synthesizer Totoro. Check out his website with nice explanations, e.g. on the filter (we use the same filter on Ilse). We extended the design for external voltage control on filter, oscillators and LFO. Unlike Totoro, Ilse is designed around a unique oscillator design, which integrates the exponential conversion directly into the oscillator core. This results in an efficient circuitry saving you build time, parts and costs.PCB and face-plate are manufactured in the EU.Features:Functions• Two saw tooth oscillators• Bridged-T low pass filter with resonance control• Triangle LFO with speed control, and routing to filter and/or oscillators• Simple mixer and detune for oscillatorsControls• LFO Speed, Filter Modulation, Osc Modulation• Filter Cutoff, Filter Resonance• Tuning, Osc2 Detune• Osc1/Osc2 (Filter in)• Output volumeInput/Output• 1V/Oct CV for oscillators (0-5V)• Gate (0-5V)• Filter cutoff (0-5V)• External filter input• Volume controlled output• LFO Speed (linear, via solder pad on back, 0-8V)• Oscillator 2 detune (linear, via via solder pad on back, 0-8V)DIY-Kit-Type:THT-Kit-1.

CubuSynth - Dual CS-20 VCF

sold out at the moment

The CubuSynth Dual CS-20 VCF is a versatile module that combines two 12db filter cores in a dual/stereo configuration. It is inspired by the iconic Korg MS-20 synthesizer, offering similar sound characteristics while the resonance can be pushed even further.The module provides multiple filter modes, including low pass and high pass, which can be blended together to create a diverse range of filter responses. This allows you to shape your audio signal in various ways, from smooth and warm low pass filtering to more aggressive high pass filtering.One of the standout features of the CS-20 VCF is its self-oscillating resonance capability. When the resonance is turned up, the filter produces a sine wave that can be used as an additional sound source. This feature adds to the versatility of the module, allowing you to create complex and evolving sounds and even cross-FM modulation possibilities.The frequency and resonance parameters can be controlled via control voltage (CV) inputs. The frequency CV input can be attenuverted, meaning it can both attenuate and invert the incoming CV signal. This gives you precise control over the modulation depth and direction for frequency modulation.The resonance CV input includes an attenuator, allowing you to adjust the modulation depth for the resonance parameter. This feature gives you the flexibility to add dynamic and expressive modulation to your sounds.Additionally, the CS-20 VCF provides a 1V/Oct input, which allows you to control the filter's frequency using a standard 1V/Oct control voltage. This input is stable over a range of at least 2 to 3 octaves, ensuring melodic tracking and integration with other modular synthesizer components.Overall, the CubuSynth Dual CS-20 VCF offers a powerful and flexible filtering solution with intuitive routing and modulation options. It is designed to inspire creativity and provide a wide range of sonic possibilities for your modular synthesizer setup.Features:• 2 individual Filter cores with common Frequency and Resonance controls• CV control over Frequency and Resonance for each Filter core• Self-oscillating Resonance with LED feedback circuit (visible on the Front)• 1 V/oct input, tracking over 2~3 octaves• Frequency Range: 22 Hz - 20 kHz• Blend between LP / HP Filter modes• Ability to use as 2 pole (12db) stereo HP/LP Filter, 4 pole (24db) mono LP/HP or a Band Pass (12db) Filter• Cross FM Modulation possibleDIY-Kit-Type:THT-Kit-1.
