An Intelligent Musical Instrument

An intelligent musical instrument for today’s computers. Generate rich counterpoint and unexpected melodies with simple computer mouse and trackpad movements.

A Different Kind of Instrument

Music Mouse turns simple mouse movements into melody and counterpoint in real time, letting you play music directly instead of programming it.

Independent horizontal and vertical motion generate interlocking musical lines, while built-in harmonic logic keeps everything musically coherent.

Use it to improvise, explore new ideas, or drive external instruments with expressive, human control.

How to Play Music Mouse

Play as a Standalone Instrument

Music Mouse is a standalone app by design, just like the original in 1986. It launches instantly, stays focused, and responds with the speed and feel of a real instrument.

Run through Effects

Send Music Mouse into delays, reverbs, modulation, or granular effects and it comes alive. Because it plays differently than traditional controllers, effects respond in fluid, expressive, constantly moving ways.

Use as a MIDI Source

Music Mouse can drive your DAW, generating MIDI that sparks new harmonic ideas and breaks you out of recognizable patterns. It’s a powerful way to discover melodies and rhythms you wouldn’t normally play on a keyboard.
