Moonhunter Sonics — iOS music apps

Music tools that think in color

We build apps for musicians where every pitch has a color — and color carries real musical meaning. Two apps, one studio.

The tuner · iOS

Kromatonic

Coming soon

An instrument tuner built loud. Big shapes, hard edges, zero clutter — and a color feature, Kromatonic, that gives every pitch class its own hue. The moment a note drifts, you see it as clearly as you hear it.

  • Pitch becomes color Every one of the twelve tones maps to a fixed, vivid hue — a whole melody laid out as a run of colors.
  • Readable across the room Octave, note, and cents deviation in type you can see from the back of the rehearsal space.
  • Flat, sharp, or dead on The whole screen tells you. No squinting at a trembling needle.
  • An instrument, not a gadget Heavy type, blunt geometry, hard-edged contrast. It looks like a tool you'd trust on stage.

The synthesizer · iOS

Quantachrome

Coming soon

A synthesizer whose visualizer isn't decoration — it's the sound itself. Every harmonic you play is drawn as a circular wave, and the waves interfere on screen the way they do in the air.

  • The picture is the sound Every harmonic of every note becomes a circular wave. They interfere on screen exactly as waves do — the pattern you see is the harmonic content you hear.
  • A full synth, not a toy Two wavetable oscillators per voice, a lowpass filter with its own envelope, LFOs, glide, delay and reverb — sixteen voices of polyphony.
  • Played by hand or by MIDI A multi-touch piano keyboard is built in, with octave shifts. Plug in a hardware MIDI controller, or play MIDI files straight through the synth.
  • Stereo, end to end The visualizer renders the left and right channels separately, with panning folded into the image — what you see is as wide as what you hear.
