Dirty hacks and radical Eurorack pleasures!

28 December 2020 | 5 – 8pm @ online

In the environment of intense DITOxication at last year’s PIFcamp, Klemens Kohlweis and Staš Vrenko, basing off John Richards’ (aka Dirty Electronics) Radical Chip, have designed Dirty Module – an algorithmic wavetable oscillator in the 4HP Eurorack format!

Radical Chip is a programmable PIC microprocessor that reads 5 stored wavetables with the use of 9 manipulable one-liner algorithms, opening up a plethora of sound possibilities, useful for tonal, percussive, textural and drone purposes. Dirty Module literally integrates the Radical Chip into its circuit as well as resonates with its structure and sound capabilities. The module can be operated with two potentiometers for manipulating the algorithm and a button for changing the algorithm and wavetable combination, via three CV inputs and two potentiometers to lower the input CV signals.

Each kit comes with a uniquely designed 3D-printed front panel.


Klemens Kohlweisis an artist and a toolmaker. He builds installations involving sound using a range of techniques spanning from home-made electronics controlling wind instruments to gaffer-taping loudspeakers onto hacked vacuum cleaning robots. As part of the collective ‘anulla’ he’s playing concerts/performances with misused everyday objects and worked on the stage and sound design for the theatre production ‘Union of Global Artificial Intelligence’ in 2019. He is currently finishing his diploma at the Academy of Fine Arts Vienna and working as an educator at the technical museum in Vienna.

Staš Vrenko is an artist, musician and electronic instrument designer. He holds an MA (cum laude) in sculpture from the Ljubljana Academy of Fine Arts and Design for which he received the student Prešeren Award. His practice involves various fields of art with a strong focus on sound exploration, electronic media and technologies, kineticism and performativity. In the past few years, he has presented various solo projects: Record (Kino Šiška), Loops in Transmission (osmo/za), Adoption Techniques (P74) and Connective (MoTA). He has also been featured on group exhibitions at the international festival Agora Creative (Grenoble), SCCA Ljubljana, Lighting Guerrilla Festival, MFRU_25, Kiblix, Vžigalica Gallery and Škuc Gallery, among many others.
