Remote extension module that allows to connect 16 signals (audio, CV, gate or whatever) between large or separated cases.
To avoid bleeding, signals are isolated with a ground line between them (both in the ribbon cable and the printed circuit).
The bundle consists in two XT modules and two ribbon cables ( 1 m ).

The audio AD/DA is 24 bit, 48 KHz, the internal audio handle is 32 bit float.
The CV AD/DA is 16/12 bits, 12 KHz.
Each channel has 6 modes available. By default 2 parameters are assigned to the horizontal & vertical axes but this can be easily tweaked, so it’s possible to control any of them (frequency, symmetry, offset or amplitude of the LFO, for example) not only with the joystick but with the 2 CV inputs.
The polarity control & offset of every parameter can also be modified on every mode and every channel.
6 presets for store and recall not only the joystick assignment and settings but all the parameter values for all modes and channels.
Size: 12 HP
The A/B Switch selects between A and B and the middle position of the switch is a "mute", works with any kind of signal (cv or audio) and is bidirectional.
This is an utility module that I made for switching stereo signals, but other uses are possible:
Select between 2 stereo sources.
Select between 2 stereo destinations.
Bypass control for mono signal processing.
Routing control for a single signal.
Panel is reversible so it can be mounted with the switches on the right or left.
Size: 8 HP
This is a 3HP version of the Douts module,
a breakout box for the direct outs of the TexMix. Valid for '4StereoChannels' and '4MonoChannels' version 1.5 & 1.6, for earlier channel expander versions some DIY would be required (check this).
Each module has 8 outputs so it could have 2x '4MonoChannels' connected or 1x '4StereoChannels'.
The orientation of the 8 pin ribbon cable is marked by the 'DIRECT OUTS' legend on the PCB of the channel expanders (mono or stereo) and a white line in the DOUTS input header.
DOUTS has 3 headers on the back, 2 of them are for 4 Mono Channels, the other one, labeled STEREO, is for 4 Stereo Channels.
Size: 3hp
This is a 4 stereo channels expansion. Several of this modules can be added to get more stereo channels.

Radioactive is a small but powerful 14-bit analog modelling voltage-controlled digital sound source: a complete voice Eurorack module in 6HP. It consists of 3 simultaneous independent oscillators, voltage-controlled AR/ASR transient generator, voltage-controlled pitch slew (glide) and voltage-controlled waveshaper with 5 different modes, but that's just the beginning. Its forte consists of selectable gate/trigger/constant envelope timing signals, rather unique 3-voice polyphonic mode, semitone-quantized mode, voltage-controlled waveform selection, on-the-fly selectable 10Vpp CV input range with offset (except for Pitch), a few experimental features, and then some.
Under the hood, it's a chiptune-inspired wavetable-gnawing sound cruncher with a mind of it's own, and oh boy it's dirty. It could be described as raw and untamed, but it would probably be an understatement.

FranKinksTides is a 18hp dual Tides (based on the Swirls pcb layout) with the max/min circuit from Kinks and some switches for sync, quadrature, pll and FM operation . It can be a double/complex oscillator, a dual function generator or any combination of oscillator, LFO and Envelope generator with lots of cv control plus some interesting cross-modulation and sync features.
FranKinksTides is a dual digital waveform generator providing both single-shot and cyclic operation modes, and covering a very wide range of frequencies from 0.5mHz to 10kHz. As such, it can serve as an AD or AR envelope generator, a LFO, or an audio oscillator. Its unique design allows the waveform to be controlled along 3 dimensions: curvature of the rise and fall segments (shape), relative timing of the rise and fall segments (slope), and harmonic content (smoothness).
some improvements in version 1.2:
-Mix output is now buffered, no signal bleeding on single outs.
-Mix pot controls also the balance of the signals sent to the max/min circuit.
-Uni/bi switch now also determines the signal sent to FM1.
-Clock/sync switch has now a center OFF position, no need of plugging a dummy cable in the Clock1 when using Sheeps firmware to avoid ultra fast sound bank changes.
Manual and more details here.

Size: 18hp
This module it's an expander for the trigger sequencer TUKRA.
Features 6 additional audio outputs for single channel processing and USB for MIDI in & out (midi class compliant device) to connect with Ableton, Cubase, Logic or any other DAW.
Easily configurable for envelope, LFO and stepped CV (pseudo v/oct) instead of individual audio track output.
TEO support was implemented in Tukra's firmware 1.05. Earlier versions will output nothing.
8 Channels of attenuator / attenuverter
Toggle switches to set the channel as attenuator (up) or polarizer (down)
First channel is normalized to a reference voltage (can be 5 or 10 volts, configurable in the back of the module)
Each input (except first) is normalized to the previous one, providing different versions of the same CV source.
Bicolor leds
55 mA +12V
55 mA -12V
This module is a eurorack version of the 16n Faderbank, implemented with 16 CV inputs and some other smart add ons. Almost everything is in the front panel.
This new version is oriented for firmware tweaks and future expansions, still being fully compatible with the 16n and the previous Sweet Sixteen.
Features:
Midi trs out
Jumpers on the back to swap between 'Arturia/Novation' and 'Korg/Makenoise' Midi trs standards
USB Midi out (usb midi class compliant device)
4 switches to enable bi-polar CV to Midi/i2C conversion (one for every 4 channels)
i2C via mini jack on front panel and pin header on the back of the module.
16 inputs
16 outputs
16 faders
16 bi-color leds to show what's going on in every channel
The Midi CC number and channels can be different for the TRS jack and the USB port. The firmware has been tweaked to allow also Pitch Bend, which is pretty handy because you can get much better resolution through Midi (from min to max values Midi CCs have 128 steps and Pitch Bend has a resolution of 16.384 steps).
Midi CCs, midi channels, fader calibration and i2c master settings can be customized with the web editor.
The voltage generated by every fader is up to 8v, which is good enough to control eurorack modules (like wide open/close the cutoff frequency of a filter etc).
In the midi CC messages, 0 volts will correspond to a value of 0, and 8 volts to a value of 127. But the CV to Midi can handle also negative voltages, for such task there are 4 slide switches (1 for every 4 faders) that swaps the internal voltage reference in a way that, when activated, 0 volts will be the middle position of the midi controller, -4 volts the minimum value and +4 volts the maximum. Those switches only affect the Midi/i2C outs, CV outs won't be affected by them in any way.
If you plug in a bigger voltage source (like a -5v+5v LFO or a 10v envelope) the fader will work as attenuator, so you'll be able to adapt how that signal affects the Midi CC out, covering the whole Midi CC range, saturating the waveform or just affecting it briefly.
Panel USB port is type B, which seems to be stronger than mini or micro ones.
i2C could connect directly to an ER-301, monome Ansible or a monome Teletype.
The Teensy can be powered via the internal regulator or the +5v eurorack rail (selectable via a switch on the back).
Changes from previous versions:
Function push button (for GESS presets)
Function led
Expansion header in the back
i2C pull-up switchable with jumpers (aux pcb not required)
Mate black & gold panel with brass nuts
There are 16 channels, which can be used as:
Midi controller
Manual CV generator (0 to 8v range)
Attenuator
CV to Midi CC
i2C controller
CV to i2C data

2 x Logic gates with voltage controlled boolean function selection
Logic gates are used in order to combine GATE signals to conditional event. For example it can be used to combine the GATE signals from various sequencers to get different patterns.
The module has 2 logic processors, the boolean function can be selected with the potentiometer, the CV input or the push button. The CV input range is 0 to 8V, but the potentiometer will work as an offset, so for example, placing the pot in the center position will allow the use of bipolar ±4v CV sources like LFOs etc. The input is protected so voltages over 8v will be trimmed out.
Each processor can work in 2 modes:
-Free: when the boolean function changes the output changes according to the inputs & logic type.
-Quantized: when the boolean function changes the output won't change until there is a change in any of the inputs, that way you won't get out of time beats when using the module for percussions with and LFO in the CV input ...for example.
To change the mode long press the button (1 second) if the mode you've just entered is the 'free' one you'll see a pattern on the leds.
CV input 1 can be set to be a trigger input with a jumper in the back of the module, to work just like the push button, so any incoming trigger will jump to the next boolean function, those functions are:
AND
OR
XOR
NAND
NOR
XNOR
42 mA +12V
10 mA -12V

This is a breakout box for the direct outs of the TexMix. This is valid for the '4 Stereo Channels' and '4 Mono Channels' version 1.5 & 1.6, for earlier channel expander versions some DIY would be required (scroll down). Please note that if you bought your Stereo or Mono channels expansion in our shop - it’s already the latest version.
Each module has 8 outputs so it could have 2 '4 Mono Channels' connected or 1 '4 Stereo Channels'.
Without connecting the ribbon cable it's a 3,5/6,3 adapter.
the orientation of the 8 pin ribbon cable is marked by the 'DIRECT OUTS' legend on the PCB of the channel expanders (mono or stereo) and a white line in the DOUTS input header.
DOUTS has 3 headers on the back, 2 of them are for 4 Mono Channels, the other one, labeled STEREO, is for 4 Stereo Channels.

BLINKS is a VU meter for eurorack with 24 RGB leds per channel, function is pretty easy, it has 2 inputs, one for each led column (no output btw).
PATT button changes the led pattern ( 6 patterns to choose ).
SENS button changes the input sensitivity, cycling in 7 steps.
Long pressing the PATT button enters the color scheme selection.
Long pressing SENS button enters the brightness adjustment. Most probably you'll prefer the lowest setting.
The module has a 5v regulator in case you don't have 5v in you eurorack PSU. A jumper in the back select if the led board would be powered by the 5v rail or the internal regulator (which works with the +12v rail)
Up to 3 stereo signals can be connected to a buffered input using the rear headers.
Easy DIY with only a few components, the led board is already assembled.

Vinia is a new powerful 8-channel audio generator and processor for Eurorack. Each channel is independent and has its own signal chain. This can be a multi-engine instrument, an FX processor, a combination of both, or a chain of several FX.
The sound generator section offers 2 sample players (one plays from the 16 MB internal flash memory and the other directly from the microSD card), various VCOs (VCO, multi-VCO, harmonic VCO), Karplus, a Chord generator, noise, a drum synth and modulation generators (LFO, envelope follower, envelope).
Each of these generators has a rich set of parameters for setting up your sounds. Then, there is a powerful multi-FX processor.
Tesseract Modular has added 20 different algorithms in Vinia: FM operator, filters (multimode, ladder, rubber, bandpass), a wave folder, tube saturation, delays (filter delay, delay, long delay), reverb, metallizer, grain pitch shift, and more.
These can be flexibly set in a chain per channel and offer many customization possibilities. The module also hosts a mixer. You can also save your channels in presets and work with macro parameters.
Each of the 8 channels can be independently configured as a multi-effect processor, VCO, sample player…
8 Channels
6 Audio inputs (AC coupled, tracks 7 & 8 use inputs 1 & 2)
8 Audio outputs (DC coupled)
8 trigger inputs
8 CV inputs (-5V / +5V)
Midi TRS input
2,4” color display
LFO, envelope, envelope follower, and mini sequencer per channel
The module can be used both with jacks up or down.
Audio outputs are DC coupled so it can be used to generate complex CV modulation sources too.
There are 2 types of modulation in Vinia, the first is stepped (occurs every 1,4 milliseconds approx.) and very flexible, any modulation source can modify any parameter of any track. The second is the ‘audio rate’ one (44,1 KHz), only a few parameters admit this type and both sources and destinations will be within the same track.
