An instrument for light.
Everything you need to turn a room into a reactive light show — designed to feel less like software and more like an instrument.
Real-time reactivity
Sub-frame audio analysis maps loudness, bass, and transients straight to motion. It moves the instant the music does.
GPU-accelerated
Built on Metal. Hundreds of thousands of particles at a locked 60fps — smooth even on a laptop on stage.
A library of scenes
Curl-noise fields, geometric bloom, and more — each scene tuned from the ground up to respond to sound.
Play it live
Map any parameter to a MIDI controller or your keyboard. Build moments and trigger them right on the drop.
Output anywhere
Full-screen to a projector or LED wall, or pipe into OBS and your VJ rig with Syphon and NDI.
Make it yours
Dial in color, motion, and sensitivity, then save your looks as presets and recall them mid-set.
From sound to spectacle in seconds.
Connect your audio
Mic, audio interface, or your Mac's system audio. Notchster starts listening the moment you open it.
Choose a scene
Pick a visual and shape it — color, intensity, and exactly how hard it reacts to the low end.
Perform & output
Send it full-screen to the room and play the visuals live, right alongside the music.
Don't just read about it. Hear it move.

Questions, answered.
A live-visuals instrument for your Mac. It listens to audio — your mic, an interface, or your system audio — and turns it into GPU-rendered visuals you can perform, tweak, and project in real time.
A Mac running macOS 13 or later. It's built for Apple Silicon and runs natively on the GPU, so it stays smooth even with hundreds of thousands of particles on screen.
Yes. Alongside mic and line-in, Notchster can capture your system audio, so anything coming out of your Mac — Serato, Ableton, a browser tab — drives the visuals.
Full-screen Notchster to a second display or projector, or send it into your streaming and VJ setup with Syphon and NDI outputs.
No. Everything runs locally on your machine — no cloud, no accounts required to perform. Your set never depends on a connection.
