D3MIX by Maffez is a passive triple level-module that lets you route signals between different paths in a clever way.First, your signal is routed between ground and a point "b", allowing you to cover simple tasks like signal starvation, attenuation, splitting and passive mixing. With creative patching you can also do some pretty interesting things like asymmetric modulations, which is illustrated and explained in more detail in the manual.Another mode lets you control between individual channels and a common "node", creating multiples in a flash, realising a 3-1 mixer or a 1-9 distributor. Experimental or pragmatic? Definitely both, and fun either way!Read more info and hear audio demos on the Maffez website. https://maffez.com/?page_id=2872Maffez developed this module in dialogue with Pedro Eustache, who uses some of the gizmos in his rack during the show "The World of Hans Zimmer" and the soundtracks of "The Mandalorian" and "Avatar: The Way of Water".

Farbfolder is an analog wavefolder for Eurorack, designed to add harmonically related overtones to an audio signal.We have always been fascinated with analogue effects circuits, and we love the way their quirks and nonlinearities inspire us to find new sounds.Farbfolder does this weird and wonderful trick of folding up the wave at the zero points, "squaring" a sine off with more and more sinusoid edges, thus adding odd harmonics.This module is excellent at adding rich harmonics to a basic waveform.

Farbshaper is a classic West Coast analog waveshaper for Eurorack, designed to shape the overtones of an audio signal with two voltage controlled stages.We have always been fascinated with analogue effects circuits, and we love the way their quirks and nonlinearities inspire us to find new sounds.Farbshaper is based on a classic circuit that turns a ramp into a sine, and was historically used in function generators and oscillators. On any other signal it will add one or multiple wave folds.The circuit produces opposite offsets internally, so the knob settings interact strongly and are fun to automate with CV.This module is excellent to use as a non-linear shaper for acoustic and electronic sounds, ranging from gentle timbral transformation to colourful wavefolding.It is part of our Farbfilter (colour filter) range of sound colouring modules, offering a wide sonic palette from lending subtle colour to rich timbre bending tones in 4 HP.Farbshaper is designed to be an easy, beginner-friendly DIY build you can solder yourself.Features:• Classic analog West Coast circuit: multi stage Waveshaper / -folder.• CV and Attenuation to control first single Fold stage.• CV and Attenuation to control Pleat, a second dual Fold stage.• Internal CV offset creates dead zones for VCA-like use.• Backlit panel offers instant visual feedback over CV.• Flip panel: with or without number.DIY-Kit-Type:Semi-DIY-Kit.

zetaSID is a compact 4HP Eurorack synthesizer voice that brings the legendary SID sound into a modern modular format. Based on the MIDIbox SID synthesis engine, it offers deep digital sound design, animated OLED visual feedback and powerful expansion through the midiphy phybus system.A single zetaSID works as a monophonic CV/gate-controlled SID voice, while multiple units can be linked into a larger polyphonic instrument. With nexusMIDI and phybus expansion, zetaSID can grow into a full MIDI-controlled synthesizer with up to six stereo voices, while unused CV and gate inputs can be reassigned as additional modulation sources.The sound engine includes six LFOs, two advanced envelopes, eight modulation paths, four wave sequencers, three oscillator arpeggiators and a 24 × 14 trigger matrix. This allows everything from classic chiptune tones and animated arpeggios to acid-style basslines, evolving digital textures and percussive C64-inspired sounds. zetaSID also includes Lead, Bassline and Drum engines, giving it a wide range of synthesis options in a very small footprint.The integrated OLED display visualizes oscillator outputs, arpeggio patterns, filter curves and other sound parameters, making patch editing more immediate. Thanks to phybus UI cooperation, multiple zetaSID modules can work together as one expanded interface, with different units controlling different parts of the same patch.zetaSID ships with 100 preset patches in its internal ROM bank and supports optional microSD storage for session recall and patch handling. With its milled aluminium front panel, compact depth and strong modular connectivity, zetaSID is a powerful SID-inspired Eurorack voice for chiptune, basslines, drums, experimental synthesis and expandable polyphonic setups.Features• Compact 4HP Eurorack SID synthesizer voice.• Based on the MIDIbox SID synthesis engine.• Monophonic CV/gate control or expandable polyphonic MIDI setup.• phybus expansion for multi-unit linking and UI cooperation.• Up to six stereo voices with 12 linked zetaSID modules.• Lead, Bassline and Drum sound engines.• Six LFOs, two envelopes and eight modulation paths.• Four wave sequencers and three oscillator arpeggiators.• 24 × 14 event trigger matrix for deep sound design.• Animated OLED display for oscillator, filter and pattern visualization.• 100 factory ROM patches included.• Optional microSD support for saving and recalling sessions.• CV input, gate input and Eurorack audio output.

The MAT 16X8 is an extremely compact ultra light audio and MIDI interface for mobile live setups, hardware synthesizers, drum machines, modular systems and external effects units. With 16 inputs, 8 outputs and extensive MIDI connectivity, it offers a flexible solution for performance, recording and complex routing in a format that fits easily into any mobile setup.In combination with a computer, iPad, MPC or any other USB Audio Class 2.0 compatible host system, the MAT 16X8 can be used via the host software as a performance mixer, multitrack recorder, effects routing hub or compact studio interface. For modular systems, a level converter may be required depending on the application.The interface operates at 24-bit resolution with sample rates of up to 96 kHz and high-quality converters offering up to 110 dB signal-to-noise ratio. Thanks to its Direct-In concept without additional preamps, the noise floor remains especially low, making it ideal for line-level signals from synthesizers, grooveboxes and drum machines. The very low roundtrip latency of up to 3.7 ms ensures a direct playing feel for live performance and recording.Measuring only 222 × 60 × 11 mm and weighing just 135 g, the MAT 16X8 is exceptionally lightweight and space-saving. It is powered directly via USB and requires no external power supply. The 16 inputs and 8 outputs are provided through robust 3.5 mm TRS stereo jacks, with enough spacing for common connectors. Standard Y-cables can be used for 6.3 mm jack connections or mono signals.An adjustable headphone amplifier with pre-listening function allows separate monitoring of output 1/2 or 3/4. For MIDI setups, the interface provides a TRS-A/B auto-sensing MIDI input and two independently addressable TRS-A MIDI outputs, making it easy to integrate more complex devices or create separate clock routings.The DC-coupled outputs allow CV control in the range of ±2.5 V, expanding the interface for modular applications. The reduced, robust PCB design without a traditional enclosure keeps weight and height to a minimum, while synthetic rubber bands serve as scratch and slip protection and help with cable management. Design, development, final assembly and testing are carried out in Germany.Features• 16 inputs and 8 outputs in an ultra-compact format.• USB Audio Class 2.0 compatible and bus-powered.• 24-bit audio with up to 96 kHz sample rate.• High-quality converters with up to 110 dB SNR.• Direct-In concept for a low noise floor with line-level signals.• Very low latency of up to 3.7 ms roundtrip.• 8 TRS 3.5 mm stereo inputs for 16 input channels.• 4 TRS 3.5 mm stereo outputs for 8 output channels.• Adjustable headphone amplifier with pre-listening function.• TRS-A/B auto-sensing MIDI In and 2 × TRS-A MIDI Out.• DC-coupled outputs for CV applications up to ±2.5 V.• Compatible with iOS, macOS, Windows, Linux and many standalone hosts.• Only 222 × 60 × 11 mm and 135 g.• Designed, developed, assembled and tested in Germany.
