4. TUKRA

TUKRA playing the same pattern with different songs (each song has it's own settings for the drums, mixer, modulation...)

5. Making melodies with FranKinksTides as function generator
6. Tesseract Radioactive Demo 2

Radioactive is a small but powerful 14-bit analog modelling voltage-controlled digital sound source: a complete voice Eurorack module in 6HP.

See https://www.tesseractmodular.com for more. Modules featured above:

TUKRA is an 8 track eurorack trigger sequencer with audio and midi.
This module can be an ‘all in one’ solution for drums in your rack, but it 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).
32 HP

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.

Also see the demo by Stefan Tretau here.

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.

"A demo of Roman Sowa´s cool new noise maker kit, the Pierdzidelko!

via Sowa

"DIY kit is what kids today love the most, so here it is, first kit from MIDI-hardware!
It's rather complex build consisting of roughly 150 parts, so prepare for 2 hours of soldering. And hopefully you will enjoy playing it just as much as assembling it. This is four-oscillator cross-modulation drone sound generator, that can also play nice and polite sounds, even controled via external Hz/V signal. But that's not why it was made for. There are 4 identical VCOs, each producing 3 waveforms that can be separately mixed to audio output and to modulation matrix. Each VCO can frequency modulate all other 3 VCOs, so you can expect wild and crazy sounds coming out of it."

This is how it looks like assembled

with autoscillation, and cutoff cv attenuator.

E.G.
-fast fixed attack
-Release: 80ms to 1s
-Connected by default, to the attenuator of the cutoff cv, and to the VCA.
And it’s automatically disconnected when an envelope or modulation

"This is a do it yourself (DIY) full kit! For an assembled module click here.

This kit is designed to be as easy as possible for the DIY community. It is a very good kit for starting DIY’ers because of these features:

through hole components
symmetrical printed circuit board layout
low part count
no trimming/tuning required.
Only basic soldering skills and equipment are required!

Module description:

The VVCA is a dual linear VCA can be used for audio and CV signals.

The VVCA features two individual VCA’s. Each VCA behaves just like any other normal VCA when there is no cable connected to the velocity input. The velocity input offers velocity control over the CV input level, which means: The output level can be controlled by CV and Velocity.

This module uses the 5V rail (16 pin eurorack connector)!

Included items are:

Panel (128.5 x 20 x 2 mm)
PCB
All components (Resistors, capacitors, IC’s, etc.)
Connectors + hex nuts
montage screws
Rack crash protectors
16 pin power cable"
