Oscilloscope Music

Synthesizer Series

Welcome to the OMS Exploration Laboratory

Here you will find a series of musical synthesizers and sound generators which, when viewed through an X/Y oscilloscope, produce discernible shapes and interesting patterns. This is a series inspired by the works and algorithms of Jerobeam Fenderson.

While fun to look at through an oscilloscope, these sound generators are powerful sonic tools in their own right, capable of creating a range of organic, mechanical, creepy, alien sound.

Spiral Generator

A perfect compliment to PrettyScope. Generates fractal spirals that makes all kinds of bassy, throaty, vocal sound as well as insane bubbly, grinding, and alien sfx.
