Tesseract Modular

Notes: VU meter for eurorack.

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).

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.

5v not indispensable
+5v: 30 mA (on lowest brightness)
+12v: 4mA (or ~40mA if 5v rail is not used)

Notes: Dual tidal modulator with max, min & mix outs

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.

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.
small improvements for DIY:
-Bigger font size on the pcb.
-Parts renumbered for easy DIY.

Notes: Gate Expander for Sweet Sixteen mkII.

This is an expander, brings 8 gate inputs for the Sweet Sixteen mkII.

The panel is reversible, so jacks & buttons can be in the left or right side.

The orientation of the 10 pin ribbon cable is marked by the 'do not plug power here!' legend on the PCB, so it could be with the red stripe facing that in both GESS and Sweet Sixteen mkII modules.

Notes: Great value from this versatile six-channel function generator, suitable for LFOs, envelopes, slew limiting and much more. A versatile module at a good price.

Supplier's Notes:
This modules is a 6 channels function generator, each channel has an attenuverter to set the output gain, there are 2 extra outputs with mixed signals (channels 1+2+3 and 4+5+6) for complex CV

-With no signal plugged in the input, channel will self-oscillate generating an LFO of i4,8V

-With gate/trigger signals in the input, channel is an AR envelope generator

-With an stepped CV signal plugged in the input, the channel acts as a slew limiter

min attack/decay time:
0,3 milliseconds in fast mode
13 milliseconds in slow mode

Notes: Tesseract's step sequencer is designed for hands-on playability, configured as a 16-step or dual 8-step design. Unique features include a 'drunk' mode to add variety to your sequences.

Supplier notes:
Step Fader mkII is a 'hands on' eurorack dual sequencer, featuring two 8 step lines or one with 16 steps, plus quantizer, slew limiter, internal clock generator, CV inputs to control any parameter and more...

Each sequencer has independent settings for the play mode, start point, size (length), clock divider (or step repeat), transposition and duty cycle.
There are 16 presets to store & recall all the above settings plus CV input assignment, scale, tempo, step repeat and clock out ones.
The 2 channels of the quantizer can be used for processing external signals, same for the slew limiters.
The 16 illuminated buttons can be used to set several parameters, even to play the sequencer as a keyboard.

There are 3 MAIN SETUPS:
DUAL (2 totally independent 8 step sequencers)
PARALLEL (one sequencer with 2 rows of CV and 8 steps)
SINGLE (one sequencer with 16 steps)

There are also these PLAY MODES:
Normal
Reverse
Pendulum
Drunk
Random

Each sequencer features:
Clock input (clock input 1 is normalised to clock input 2)
Clock output
Reset input
Gate/Trigger output
Slew limiter output (unquantized)
V/OCT output (quantized)

Additionally, there are 2 summing outputs:
Gate/Trigger 1+2 (OR output of both G/T)
CV 1+2 (sum of both slew limiters)

Features 2 CV inputs with offset pots. Assignable parameters are mode, start, size, clock divider, key (the position of the sequencer is controlled by CV), transposition and duty cycle.

Dimensions: 26 HP

Current Draw:
85 mA +12V
36 mA -12V

Notes: Stonk it's a joystick controller with 2 channels of CV and 2 of audio. It's a CV generator, looper & audio processor.

Very hands on module which can be a chaos pad or DJ looper.

Features:

2 audio in & out (AC coupled)
2 CV in & out (DC coupled) i5V
2 extra CV outputs +/-10V
12 illuminated push buttons
CV & Audio looper (2:30 per channel)
LFO
Euclidean envelope generator
Multimode Filter
Stereo Reverb
Wave
VCA

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.

The extra CV outputs are the analogue sum and difference of the CV outputs 1 & 2.

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.

Notes: This is a 4 mono channels expansion. Several of these modules can be added to provide more channels. Every channel features:
- Mono input
- Vactrol Gate (plug a CV into the GATE IN to modulate the volume of a channel, just like a classic VCA. When nothing is plugged in the GATE IN, the gate is normalled to fully open)
-SEND A control (switchable PRE/POST, in PRE mode the signal is present regardless to the channel volume control but only if the channel switch is in ON position)
-SEND B control (post-fader)
-PAN control (only affects the master bus)
-VOLUME control (affects the master, cue and POST sends, does not affect PRE-fader send)
-ON/OFF/CUE switch: ON - channel is routed to the master bus
OFF - channel is muted
CUE - channel is routed to the cue bus

Notes: A whole lot of module for the money. Eight-track trigger sequencing with built-in drum synth, sample player and MIDI. Amazing value for studio use or live performance.

Supplier's Notes:
Trigger sequencer with audio and midi

TUKRA is an 8 track eurorack trigger sequencer with drum synth, sample player and midi.

This module can be an 'all in one' solution for drums, but also has great integration capabilities with other gear (eurorack modules, drum boxes, DAWs, midi devices and midi surface controllers).

There are no submenus, all functions and views are accessible all the time.

Brief overview:
- Up to 64 steps per pattern, 64 patterns, 64 parts and 16 songs per project. 64 projects in the microSD card.
- Play mode, clock divider, length & choke settings independent per track & pattern.
- Step value (can be used for modulation, to define the midi velocity, midi note & drum synth pitch or sample selection).

Ins & outs:
- 8 trigger/gate, clock & reset outputs. Clock & reset inputs.
- 4 CV inputs with offset potentiometers (so they're manual controls when no CV is plugged in).
- Audio L & R out (6 additional ones with the expander for independent track output).
- Front panel midi TRS in & out, and USB host for midi controllers.

Midi and audio:
- Midi note and channel configurable per track & song, midi note and velocity can be set by the step value.
- Drum synth, noise with envelope and 'one shot' sample player (factory and user banks) per track.
- Flexible sample selection (each track can play up to 128 samples).
- Mixer with volume, balance, reverb, bit crusher, filter cutoff, resonance and type (smoothly crossfades LP - BP - HP).

Modulation:
- CV & assignable midi CC plus 8 internal LFOs, 3 stepped random sources and step value.
- Modulation matrix for almost all parameters.

Rhythm variation:
- Probability for step, gate and roll.
- Euclidean Rhythm Generator.
- 'Ramifications' generative tool.
- Live view with solo, mute, fill, roll, invert pattern, reverse play direction and rotate.

Time:
- High precision clock source and low latency.
- External sync (via trigger, midi TRS or USB).
- Triplets and swing (aka 'shuffle'), triplet and swing can be generated from a straight clock input or midi clock.
- Micro grid edit, each step has 6 micro steps (24 ppq).
- Half and double tempo functions.

Notes: 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...

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.

Audio sources: Audio Input, Flash Sample Player, MicroSD Sample Player, VCO, Multi VCO, Harmonic Oscillator, Karplus, Chords, LFO, Envelope Follower, Envelope, Noise, Drum Synth

Audio processors: FM Operator, Multimode Filter, Ladder Filter, Rubber Filter, Bandpass Filter, VCA / Polarizer, Folder, Tube Saturation, Exponential Envelope, Delay, Filter Delay, Long Delay, Long Filter Delay, Reverb, Metalizer, Chorus, Modulator, Vocoder 16, Vocoder 32, Bit Crusher, Rectifier, Grain Pitch Shift, Ring Modulator

Notes: Remote extension module that allows to connect 16 signals (audio, CV, gate or whatever) between large or spread-out 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, 1.5 or 2 meters depending on the option selected).

This is a passive module, it does not draw any current.
