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. It goes straight into your DAW, hardware synth, or modular rig. Nothing simulated, no ecosystem to buy into.

Brightness drives harmonic complexity — triads through sevenths to full ninth chords as the sky intensifies.

This is not a mock‑up.It’s the real thing.
Ljómi, reading real aurora footage. It tracks colour, intensity and wave coherence, and emits the MIDI you hear. Running now, still in development.
A typical mapping
In Ljómi, brightness drives harmonic complexity. Triads become sevenths, then full ninth chords, as the sky intensifies.

What we build
One tool you can run today, two still in development. All of them output standard MIDI.
Ljómi
In developmentReads live aurora footage for colour, intensity and wave coherence, and builds harmony from it. Brightness drives complexity: triads at low intensity, up to ninth chords at full.

MIDI For Trees
Available nowPoints a camera at a forest and reads its movement. Optical flow drives scales and MIDI events, and overlays show what it detected. Runs on macOS 14+.

Who it’s for
Built for creators,
experiences, and teams
Artists & Musicians
Standard MIDI into your DAW, hardware synth, or modular rig via MIDI-to-CV. Map any visual characteristic to any musical parameter. Nothing proprietary to buy into.
For artistsTour Operators
Turn an aurora night into something guests can hear as well as see, and send them home with a recording of their own sky.
For tour operatorsTeams & Organisations
We also help teams ship software. Agile delivery and process coaching, backed by 30+ years in product development. The tools above are the evidence.
