In stock now at Thonk.

Della is a 3HP Eurorack expander module for Scrooge. This module is completely passive, and performs the simple function of exposing all 8 sequencer tracks to the outside world via dedicated sockets. Della is intended to be used with the Eurorack DIY version of Scrooge. Della connects to a header on the back of the Scrooge module, which is inaccessible in the desktop version.

Lazer Phazer is at its core a 2x System700 phaser

Lazer Phazer is at its core a 2x System700 phaser with a lot of addons. The module can work as a stereo phaser, as a mono BI-Phaser, or as two totally independent phasers, or as a 16stages phaser in series mode.

And that’s not all, the LFOs of the phasers can work independently or linked in inverted mode for stereo phase galore.
The feedback can be modulated by internal LFOs, external CVs or both of them in the same time. The kit includes 16 x 2SK30A fet transistors matched and selected from new old stock, so the retro sound it’s totally there.

This module is a collaboration between Feedback Modules and CMS-LAB.

Mylar Melodies says:

"NEW VID! I filmed a short but very sweet pure melodic bliss ambient live set by @mypandashallfly where he plays just the @musicthingmodular Workshop System, with FX from the @rebeltechnology Alchemist, and looped by the @korguk Kaoss Pad 3.

It's a lesson that less can most definitely be more when it comes to live performance. Suren by the way was playing @chris.johnson074's Lowpass Gate and Quantiser 'Utility Pair' on the Workshop.

The full set is 11 mins long. Live on the channel now, link in bio 🥳"

Patterns is a 4 channel Eurorack sequencer designe

Patterns is a 4 channel Eurorack sequencer designed for deep flexibility and hands on performance. Link in bio or go to Thonk.co.uk

Each channel supports up to 64 steps, with essential creative tools like randomisation, probability, gate length control, swing, clock divisions, and more, giving you everything you need to build evolving, dynamic rhythms.

The real power of Patterns lies in its dedicated Pattern button, your instant gateway to 16 different pattern slots. Switch between them on the fly, program your custom pattern chains, or use CV to jump between patterns and create unexpected breaks, fills, and experimental grooves.

Rhythmatic is a 6 voice analogue drum machine base

Rhythmatic is a 6 voice analogue drum machine based on the classic Roland CR-78 and updated with intuitive performance features.

In this video we show how the Music Thing Modular Minidrive can really make Rhythmatic growl and later on accompany it with some chords from the Sebsongs Bread & Butter module.

MUTES is BACK.

Mutes from Divkid goes above and beyond basic muting by allowing you to split groups of signals to multiple destinations, making it great for FX dub performing and varied signal routing.

This new unit uses VCA based technology that offers improvements in noise floor / bleed and the signal integrity passing through the channels. It also retains the well loved response and feel of the original click-free muting and the performable 3 way: MOMENTARY – OFF – ON switches.

SMITH from Tesseract Modular is an 8 inputs & 8 ou

SMITH from Tesseract Modular is an 8 inputs & 8 outputs precision buffered matrix with presets. Available now as a kit from Thonk. Link in bio.

Each of the 8 outputs can take the signal from any of the 8 inputs, allowing over 16 million possible combinations. This is not a mixer, the same input can be routed to many outputs, but several inputs can’t be present at the same output simultaneously.

The module works with both audio and CV signals, ins & outs have ±10 volts range and minimum offset (1 millivolt approx.), which makes it perfect for distributing V/Oct signals too.

8 scenes can be accessed through the dedicated push buttons but also by CV and trigger.

8 banks (with 8 scenes each, 64 scenes per preset).

8 persistent presets (with 8 banks of 8 scenes each).

This module can be used to store ‘presets’ for your live setup, allowing patch changes and easy rerouting signals with literally just pressing a button.

Another (more chaotic) way to use it is to plug several modulation sources to the inputs (such as envelopes, LFOs, sequenced CVs…) and several modulation destinations to the outputs (filter cutoff, PWM, VCAs…). If you want to introduce a variation in the sound, select a different scene or directly randomise the current one to drastically change ‘what is modulating what’.

Using audio sources can lead us to interesting territories too, sequencing waveform changes or using different processors (filter, distortion, folder…). Keep in mind that the switch performs pretty fast and the signal is passed without any modification (to preserve its accuracy, which is pretty important when using the module for v/oct) so with audio, the switching may be “clicky” depending on the sound source.

Specs:

Width: 12HP

Depth: 35mm

Power Consumption: 47 mA +12V, 14 mA -12V
