Gravity & Wind is now free to download, with a one-time Pro unlock and no subscription. Explore physics-driven MIDI performance with five free scales, 12 factory scenes, motion control, and up to five saved scenes. Presets keep playing their full saved settings. Pro adds all 24 editable scales, advanced MIDI controls, MIDI Learn, the MIDI Processor AUv3, and unlimited saved scenes. If you purchased Gravity & Wind before this change, your Pro access is included. Open the standalone app to verify your purchase, or use Restore Purchases in Settings > Pro. An external MIDI instrument is required; Gravity & Wind has no built-in sound engine.
