With the ability to connect up to 8 inputs or outputs via an ethernet cable, the PIPE-S makes it easy to connect multiple case together or avoid any cable mess accross a case. This makes it the perfect solution for simply setting up your Eurorack system in the studio or a live gig.But that's not all, PIPE-S can also be used as a multiple passive 3 section. Want to transmit precise signals like pitch CV and want to avoid crosstalk induced by passive multiples? No worries you can easily deactivate this function for each section from the connector at the back of the module.The best part is that PIPE-S is completely passive which means you can place it anywhere, it doesn't draw any current from your power supply, which perhaps makes it the simplest DIY module!PIPE-S modules are sold in pairs.The ethernet cable is not supplied with the modulesRegarding Ethernet cableWe recommend shielded Straight-Thru RJ45 cable.Using un-shielded or Crossover cable won't damage your modules but you may experience noise and or mixed channels.Due to its passive nature we also recommend to avoid long ethernet cables.DIY-Kit-Type:SMD-Kit-1.

The idea behind QBI is to fulfill two fundamental functions when patching:• Duplicate a signal• Invert a signalThese are two basic yet important and essential functions when patching. But even though they are important, we wanted them to take up as little space as possible.Therefore we imagined QBI, a module of only 2HP capable of:• Invert 4 different signals with very high precision.• Duplicate a signal on 3 outputs without losses.• Duplicate and invert a signal on 4 outputs without losses.And the best of all is that you can add these different functions together to always meet your needs when patching.DIY-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.

As its name implies you could think that SLEW/LFO is just a Slew and a LFO packed together but its more than that.We wanted to design a module around the Slew generator which is an underestimate function of a synth. Its often seen and use as a way to make portamento but we've thought it could be more than that.We wanted to design a small module so it could fit in any case. We wanted it to be ergonomic and easy to use despite its size. But we also wanted to pack as much features as possible to make it a "swiss knife module".The result is SLEW/LFO: a 4 HP wide module, that can be used as portamento, AD envelope, LFO, VCO, Filter, Envelope generator and much more.SLEW/LFO is so versatile that we use it in all our patchs, we are very pleased about it and hope you'll like it as much as we are.DIY-Kit-Type:SMD-Kit-1.

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.

The Garden Listener Eurorack module detects conductivity variations on living beings’ surface and transforms them into MIDI notes and CV signals. For once, leave those LFOs alone, and let any living conductive being modulate your signals. It detects conductivity variations on living beings’ surface and transforms them into MIDI notes, ranging from C-1 to C8, and CV signals (0 – 5V).Its behavior can be tamed through the one-knob menu from which you can choose and modify:• probes’ sensitivity (making it more or less sensitive to current variations)• scale (chromatic, major, minor, indian and arabic)• MIDI channel (from 1 up to 16)• LEDs’ brightnessIt generates trigger, gate, and CV (1V/oct). The CV output behavior can be modified via an octave selector which acts as a “CV equalizer” from which you can choose to generate CV only if the respective MIDI note lies within a certain octave range.The MIDI output allows you to take advantage of the sound of either any synthesizer equipped with a MIDI port or any VST in your DAW.The module comes with 3.5mm white probes and a set of snap-on adhesive reusable electrode pads. A MIDI-TRS type A adapter (not included) is required for the MIDI output.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.

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.
