An intelligent musical instrument for today’s computers. Generate rich counterpoint and unexpected melodies with simple computer mouse and trackpad movements.
An Intelligent Musical 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
- Standalone
- FX
- MIDI
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.
Listen as we use keyboard shortcuts to change the sound by applying pitch modulation, filter, and tremolo effects.
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.
Listen as we send Music Mouse through Temperance Pro, using the Air Minor Drone preset.
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.
It works with Ableton Live (shown here), Logic Pro, and any MIDI-enabled software or hardware synths.

With SplitEQ you can hear and even see your sound in new ways. Our Structural approach mimics the way in which we interpret sound and our spectrum display offers an inside look into what you’re hearing. Solo only the transients, or a single band, or only the transients on a single band. Use the real-time spectrum analyzer to track down problematic resonances or transients by displaying the tonal and transient streams separately. SplitEQ adds a new dimension to your trouble-shooting toolkit.
Our team took all the knowledge they had about recording, threw it out the window, then headed down to the studio to lay down some badly recorded tracks. Double-headed kick drum with no port? Check. Ill-advised mic placement on snare? Check. Why? To prove that SplitEQ works well on a wide range of sonically challenged material. We’ve created an entire folder of presets for those less-than-perfect recordings.
SplitEQ comes with a Factory Library of over 150 presets to solve many of today’s standard corrective and complex mixing problems in a cleaner and faster way. The presets are designed to Enhance, Repair, Rebalance, and Widen various instruments including drums, vocals, guitar, and more. A/B comparison and Undo/Redo make it easy to explore ideas without losing where you started.
