MIDIx vs MIDI World
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
MIDIx
This app uses physics simulations to generate expressive MIDI data. Control parameters through object movement or create generative note sequences. It's a unique tool for musicians seeking organic and evolving soundscapes.
- Physics-driven MIDI CC generation
- Generative MIDI note sequencing
- AUv3 plugin support
- Customizable physics scenes
- Built-in scale library
- Real-time modulation
- Universal app for iOS and Mac

MIDIx brings a new dimension to MIDI control. Instead of programming sequences or drawing automation, you let physics do the work. Objects bounce, fall, orbit, and collide — and every movement becomes expressive MIDI data in real time. MIDIx is a universal app for iPhone, iPad and Mac, and supports AUv3 so you can use it as a plugin directly in your favorite host. Organic CC Controller The CC page gives you 8 independent physics scenes, each generating two MIDI CC values — X and Y — from the motion of a physical object, for up to 16 simultaneous CC streams. Each axis maps directly to its CC value, creating smooth, organic modulation that no LFO can replicate. Each output can be assigned to any MIDI CC parameter — or to a parameter of another scene, enabling complex modulation chains where one physics engine drives the behavior of another. Hit Freeze to instantly hold the current motion in place, perfect for locking in a value during a performance. Generative MIDI Sequencer The Notes page transforms physics into melody. Add as many objects as you want to the scene — each one bounces freely and triggers a MIDI note every time it hits the wall. Shape the motion with additional objects — Static, Bumper, Planet, and Repulsor — to create richer, more unpredictable interactions. Build evolving, generative patterns that shift organically over time. No two performances are ever the same. Define your harmonic space and select individual notes to craft any scale you need. Tap Scale Library to instantly load a preset scale: Major, Minor, Pentatonic, and many more. Features: • 8 physics scenes generating up to 16 MIDI CC streams (X and Y per scene) • Generative MIDI note sequencer with unlimited objects • Continuous or Trigger play mode, adjustable update frequency • Freeze button to instantly hold the current motion • Adjustable min/max range per scene to fine-tune CC output • Assign any CC or scene parameter as a modulation source • Static, Bumper, Planet, and Repulsor objects for richer motion • Built-in Scale Library with custom scale editing • Adjustable root note, base octave, octave count, and note duration • Notes custom mode (select the notes you want) • Preset import & export • Randomizer • Undo support • Built-in user guide • Background audio support • Full MIDI support & MIDI Mapping • Full AUv3 support — standalone or as a plugin in your favorite host • Universal app for iPhone, iPad, and Mac Questions or feedback?

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.

Verdict
The clearest difference is review sentiment: MIDIx at 100% against MIDI World's 0%. MIDIx also leads on rating (5.0 vs 2.0) and update cadence (every 8 days vs every 7 months). MIDI World's advantage is price ($0.99 vs $8.99). On ads, in-app purchases and monetization model there is nothing between them.
