Jerobeam Fenderson & Hansi Raber: Introduction to Oscilloscope Music

Three-day workshop about the basics of oscilloscope music!

16 – 18 May 2023 | 5 – 8pm @ 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 three-day workshop Jerobeam Fenderson and Hansi Raber will explain the basics of oscilloscope music while providing hands-on instructions how to use lasers and oscilloscopes. 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.


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.
