Nature to sound, in real time
Nature's most
beautiful visual,
now in stereo
We build computer vision systems that watch the aurora, forests, and anything else that moves, and play what they see as standard MIDI — straight into your DAW, hardware synth, or modular rig. Nothing simulated, no ecosystem to buy into.

This is not a mock-up.
It's the real thing.
Ljómi, reading real aurora footage — tracking colour, intensity and wave coherence, and emitting the MIDI you hear. Running now, still in development.
How it works
- Input
- Live camera or video file
- Analysis
- Computer vision — colour, movement, flow
- Output
- Standard MIDI: notes, chords, CC
- Routes to
- Any DAW, hardware synth, or modular via CV
- Platform
- macOS
In Ljómi, brightness drives harmonic complexity — triads through sevenths to full ninth chords as the sky intensifies. MIDI For Trees applies the same engine to optical flow in a forest.

What we build
One tool you can run today, two still in development. All of them output standard MIDI.
Ljómi
Reads live aurora footage — colour, intensity, wave coherence — and builds harmony from it. Brightness drives complexity: triads at low intensity, up to ninth chords at full.
In developmentMIDI For Trees
Points a camera at a forest and reads its movement. Optical flow drives scales and MIDI events, with overlays showing exactly what it detected. Runs on macOS 14+.
Available nowVisionMIDI Live
YOLOv11 object detection with persistent tracking, mapping anything it sees onto a configurable virtual piano overlay.
