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.

RANDOM8 is an eight-channel random CV generator and looping voltage sequencer designed for improvisation, generative patching and live performance. Developed in collaboration with Mylar Melodies, it delivers random, repeating and slowly evolving control voltages in a compact 8HP Eurorack module.Each channel generates independent stepped or smoothed voltages from 0–10V. Incoming triggers are normalled between channels, allowing a single trigger source to control all eight outputs or additional triggers to create independent groups. Dedicated attenuators set the output range of each channel, while loop lengths from 1 to 32 steps make it easy to capture and repeat modulation phrases.A single button press switches a channel between looping and evolving operation. Pressing it again locks the current phrase, while a double press returns the channel to fully random generation. Per-channel probability, trigger division, offset and slide provide detailed control over the timing and movement of each voltage. Eight random generation modes include different voltage distributions, alternating high and low values, and wandering modulation that behaves like an invisible hand moving a control.The built-in pitch quantizer transforms any channel into a melodic sequencer, with 14 musical scales, an unquantized mode and a dedicated octave scale. RANDOM8 can generate eight melodies simultaneously or combine pitch sequencing with modulation, animation and LFO-style movement across an entire Eurorack system.Eight presets store the complete module configuration for quick recall, and the one-layer menu system keeps advanced functions accessible without a display.Features• Eight independent random, looping and evolving CV channels.• Adjustable loop lengths from 1 to 32 steps.• Per-channel pitch quantizer with 16 scale options.• Eight selectable random voltage generation modes.• Slide for smooth modulation, LFO shapes and acid-style sequences.• Per-channel probability, trigger divider and voltage offset.• Cascading normalled trigger inputs for grouped modulation.• Individual output attenuators and 0–10V unipolar outputs.• Eight presets for saving and recalling complete configurations.• USB-C firmware updates and free VCV Rack version.• Compact 8HP design with a depth of 30mm.• Power consumption: +12V 60mA, −12V 12mA.

DC is a unique and innovative module that combines the strength of both Averager and Unity Gain mixers without their weaknesses. Along with some additional unique features that make it stand out from other mixers on the market.To create DC we had to rethink the mixer, start from scratch, try new design, prototype many circuits and fail in order to succeed. The result is DC a new type of mixer that offer low noise floor, stable output signal and mix accurately signal without introducing any distortion, clipping, attenuation or unwanted noise and those regardless of the number of inputs signals or their gain.We called this new mixer design a «Combinator,» and the name «DC» stands for «Dual Combinator.» This versatile mixer can function as a dual-channel, mixing up to 3 inputs into a single output, or as a single-channel, allowing up to 5 inputs to be mixed into a single output.We put time and effort into the design of DC because we think that it is an essential module in any Eurorack system. It offers a ratio size, functionality, simplicity that no other mixer offers.DC may seem like a simple utility module, but make no mistake, small things done well can make a big difference.DIY-Kit-Type:SMD-Kit-1.

DUAL MULTI is a dual buffered multiples.It can be configured as 1 input 6 outputs 1:6 or 2 inputs and 3 outputs each 1:3.Input 2 is normaled to input 1, if nothing is plugged into input 2 you will have 6 copies of input 1 else you will have 3 copies of input 1 and 3 copies of input 2.Buffered multiples have advantages over passive multiples. Since passive multiples split the signal, in case of voltage-critical signal such as V/Oct to VCO, the pitch will vary from one output to the other. With buffered multiples each output will be a perfect copy of the input. Because buffered multis isolate their outputs from the input, any faults or shorts present at the input will not pass through to a connected module.DIY-Kit-Type:SMD-Kit-1.

Now introducing PIPE in our sleek Black & Gold theme, featuring a reversible faceplate. Feel like installing your PIPE upside down? No worries – just unscrew the 8 jnuts, flip the faceplate, and put everything back together and Voila! You can now use your PIPE with the connector facing down!With the ability to connect up to 8 inputs or outputs via an ethernet cable, the PIPE-S makes it easy to connect multiple cases 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 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 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 modules are sold by pair.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.
