MIDI World

Turn motion, weather, location, health, and over 30 sensor data streams into multitrack MIDI. Record, preview, export .mid — your world is the instrument.

MIDIWorld turns sensors and live data into MIDI control and notes. Map accelerometer, gyroscope, compass, GPS, barometer, microphone level, touch, light, proximity, and device motion into your performances. Layer weather, air quality, tides, visibility, seismic activity, place density, and market or FX-style feeds where available.

Record multitrack sessions, adjust each source with per-track controls, and preview what you captured. Export Standard MIDI Files to use in any DAW or hardware that accepts MIDI. Optional audio export is available where the app supports it.

Presets help you start quickly — from motion and tilt to weather, urban, health-driven, and experimental setups. Themes keep the interface comfortable for studio or stage.

Permissions (Motion, Microphone, Location — including background when your session needs it — Health, Bluetooth) are used only to drive MIDI and related features on your device, as described in the system prompts and in our Privacy Policy.

Whether you are sonifying a ride, the forecast, or generative patches from your environment, MIDIWorld connects world data to music.
