Euler Visual Synthesizer

Euler Visual Synthesizer
Music Visualizer & Visual Synth

Euler Visual Synthesizer (EVS) is a visual instrument for sound and motion.
Explore animated, audio-reactive geometry — or design your own — using a synthesizer-style interface inspired by classic audio tools.

EVS works like a synth, but instead of creating sound, it creates living geometry. Oscillators, LFOs, modulation sources, mixers, and effects shape animated visuals that pulse, rotate, and evolve in real time — no programming required.

Turn a few knobs and watch mathematics come alive.

DESIGN OR PERFORM — YOUR CHOICE

Design Mode
Dive into a full visual synthesis environment with oscillators, modulation, mixing, and effects such as feedback (similar to audio delay) and bloom (similar to reverb). Shapes you create can be saved as Presets and organized into Banks — just like patches on an audio synthesizer.

Performance Mode
Prefer something more immediate? Performance Mode lets you:
- Tap keys to cycle through presets
- Use a large interactive XY Pad to modulate visuals in real time
- Run hands-free playback using Auto Play (sequence or shuffle)

Perfect for live visuals, ambient displays, or interactive exploration.
