Introduction to Vector Synthesis (open lab/workshop/live set)

29 – 30 January 2019 | 5 – 9pm @ osmo/za, Ljubljana

Some call it oscilloscope music, and some call it vector synthesis. But the idea remains the same: audio waveforms control the vertical and horizontal movements of a single beam of light to trace shapes, points and curves with a direct relationship between sound and image.

During the two-day open lab, Jerobeam Fenderson and Hansi Raber will explain the basics of vector synthesis while providing hands-on instructions with a set of basic oscilloscope music hardware: an oscilloscope, a laptop and a sound card. The artists will display different custom-made software tools to support the making such music, and explain some of the tricks they use to achieve the visuals and sound they want. You can drop by at any time to get a hands-on introduction on the topic and nerd out about how cool analogue oscilloscopes are!

Thursday 31 Jan, 19:00 @ Slovenian Cinematheque

“Jerobeam Fenderson is one to watch, that much is certain. He’s shaping up to be the Shirobon of the oscilloscope scene. His live shows are reportedly an incomparable experience.” STEEMIT

“Oscilloscope Music” is an audio-visual project where the visuals are drawn by the music’s own soundwaves. In order to get the closest possible correlation between image and sound, the same signal that is connected to the left and right speakers is also connected to an analogue oscilloscope’s X and Y inputs, producing Lissajous figures and complex 3D graphics. Over the span of five years, Jerobeam Fenderson and Hansi3D have created ever more elaborate techniques to explore this largely uncharted field of audio-visual music. Their live set will include new material from their upcoming EP.


Jerobeam Fenderson is a sound artist and electronic technician, based in Austria. His Oscilloscope Music project is an audiovisual experience, where images are drawn with sound. Waveforms are fed simulataneously into a set of stereo speakers and the X/Y-inputs of an oscilloscope. The identical signal is observed by both listening and looking at it. The process of creating sounds that look good rules out most conventional methods of synthesis and mixing, but at the same time opens up a mesmerizing dimension of synesthetic geometry.

Hansi grew up in Austria, he still lives there. He really likes math, music and programming, so making oscilloscope music is the perfect rabbit hole for him.
