Gravity & Wind is a physics-driven generative MIDI sequencer and performance controller for iPhone and iPad. Build evolving sequences with Timed generation, hold an exact population with Fixed mode, or tap the field to perform directly. Shape gravity, directional dual-noise wind, bounce, and velocity response, then turn floor impacts into quantized MIDI notes. Free features include five scales (Major, Natural Minor, Major Pentatonic, Minor Pentatonic and Chromatic), 12 factory scenes, motion control, all generation modes, basic CoreMIDI Note/Velocity output, output channels, Bluetooth MIDI, manual sustain-pedal forwarding and up to five user scenes. Presets play with their saved scales, MIDI/Auto pitch, CC and sustain settings even in the free version. You can turn advanced settings off, edit basic parameters, and save within the five-scene limit. Enabling or changing advanced modes requires Pro; reloading a preset restores its settings. MIDI Learn/mappings and MIDI ball triggers remain Pro features. A single, permanent Pro in-app purchase unlocks choosing all 24 scales, enabling and editing advanced preset modes, and the MIDI Processor AUv3 with host sync, automation and project recall; MIDI chord pitch control and Channel 2 ball triggers; MIDI Learn; scene-energy CC 1, Wind CC 2, Direction CC 3; Held and chord-aware Automatic Sustain; and unlimited user scenes shared with the AU. No subscription. Eligible customers who purchased the app before the switch receive Pro automatically. Gravity & Wind has no built-in sound source. Route its MIDI to a software instrument, hardware synthesizer, or DAW. No separate account registration, advertising, or third-party analytics. Purchases and restoration use your Apple Account through the App Store.
