GETREKT is a full analogue waveshaper - an aggressive one. Disrupt and Pieces are analog touch controls; they act like potentiometers and they keep the value once the finger is lifted from the surface.DISRUPT: controls how much the output is affected by the waveshaper circuit. At maximum it will fold and create a total harmonic distortion.PIECES: the pulse width of the resulting transformed wave.Both parameters have a dedicated reactive CV input. If connected, the touch potentiometer act as an offset of the incoming signal.The circuit is designed to invert the polarity of any given input.Features:• Clipping and folding analog waveshaper circuit.• Touch Controls on the amount of effect and PWM.• Reactive CV inputs on both parameters.• Inverts the polarity of any given input.• Works with audio and CV sources.• Single board design - extremely skiff friendly.• “Whatever” power connector a.k.a. don’t mind the polarity.DIY-Kit-Type:SMD-Kit-1.

GITGUD is a pack of 9 individual LFOs - 5 squares and 4 triangle waves.The frequency is set with analog touch controls; they act like potentiometers and they keep the value once the finger is lifted from the surface.As it takes time to turn a pot, it takes time to interact with these controls:bridge with your finger the first line and the center to decrease the frequency or the center and the last one to increment. A red and a blue LEDs will light up to give visual feedback of the speed of that LFO. This is a full analogue continuous control, designed to be an expressive and interactive gateway to decrease the boundaries between the user, the environment and the music-making-devices.Features:• 9 individual analog touch LFOs with toggle switches to chain them.• Individual touch potentiometers to set their rate.• Frequency range from 0.25 Hz - 15 BPM to 20 Hz - 1.200 BPM.• Single board design - extremely skiff friendly.• “Whatever” power connector a.k.a. don’t mind the polarity.

Analog optocoupler filther.GOBLET is an analog filter and distortion unit with some added quirks and extra controls. Start with both faders - frequency and resonance - at maximum, turn the trimmers fully clockwise and set the feedback pot at 0. Now insert an input and take the output either from the lowpass out or the notch out. Start to turn the frequency trimmer until the resonance kicks in. Now adjust the resonance trimmer to your taste. The faders now have full range of responsiveness. Adjust the feedback and start the filthering. For extra distortion interact with the two touch plates and the central momentary button.Features:• Unique analog two pole circuit with custom optocouplers fed directly in the feedback path.• Two step controls and individual CV inputs on frequency and resonance for precise sound sculpting.• Dedicated potentiometer for the total amount of feedback.• A performance-oriented momentary switch for extra distortion.• Two expressive touch points to make your body interact with the circuit.• Rhythmically oriented accent CV input.• Two outputs - a smoother LP and an aggressive notch.• Works with audio and CV sources.• Single board design - extremely skiff friendly.• “Whatever” power connector a.k.a. don’t mind the polarity.DIY-Kit-Type:SMD-Kit-1.

Macro ControllerKNOBI is a multi-tool able to mix, attenuate, invert, display and multiply any kind of signal. Knobi can serve a wide range of purposes thanks to its internal signal path that makes use of some of the most useful building blocks of analog synthesis: a 4-channel mixer, a three-range offset, an attenuverter, a fixed manual gate and lastly a cascading multiple derived from the output stage of Agogô.a, b, c and d are Knobi’s inputs while r is a fixed 5v reference output. The toggle switch next to d sets the range of the offset - the big knob below the meter. Connect a signal into one of the inputs to visualize its voltage value in the three digits meter. Keep in mind that this reading happens post offset and attenuverter - the smaller knob with (-) and (+) indications.The pushbutton next to x4 adds a gate of 5v to the mix: with no input connected it will act as a manual gate output. Autopatch the r reference output into one of the inputs to use Knobi as a macro controller thanks the offset knob and switch to set the range and the attenuverter.x1, x2, x3 and x4 are all cascading copies of the final signal path. Plugging a cable will break the normalization and the multiplication will reset starting from the next output. Four cables plugged in will output a copy at the same factor x1 - unity gain - making Knobi a versatile buffered multiple.Features:• Thermally compensated 5v voltage source with dedicated output.• Four channel mixer with four buffered output.• Built in 3 digits voltage meter post mix / attenuation / inversion.• Offset with a dedicated three positions range toggle.• Manual gate button tied to the mix.• 4 cascading outputs in an open design configuration.• Unique signal path: mix - attenuate - invert - add - visualize - multiplicate.• “Whatever” power connector a.k.a. don’t mind the polarity.DIY-Kit-Type:SMD-Kit-1.

Test 3 is a purpose-designed tool for measuring voltages and currents in your Eurorack system. This means that just a single circuit board or module can now replace a convoluted test setup with multiple multimeters, custom cables etc.Two push buttons allow you to cycle the value shown on the LED display between three measurements (voltage, current and stored peak current) of the three power rails. The peak currents continually update in the background on all rails, making it ideal for quickly getting maximum current figures.Apart from measuring the current draw of a single module, Test 3 also supports testing power supplies and cables, measuring an entire system (up to 1 A of current on each rail), troubleshooting DIY modules, powering a skiff or breadboard from a larger system...Note: Test 3 is available as a (very easy) do-it-yourself project, requiring some soldering and basic tools. It can be built either as a standalone circuit board with the DIY Kit, or as a Eurorack module with both the DIY Kit and Front Panel Kit. Most dealers bundle both kits together.
