Reactional Music is revolutionizing the gaming industry by allowing any song or music to be generated in real-time around the user, creating a new era in music personalization. The Reactional ecosystem includes tools for creating Reactional Music, a cross-platform Reactional playback library, and a marketplace for curating, distributing, and selling music and sounds in games and on interactive platforms. The technology also improves workflow for music development in games and unlocks music's value in games with access to worldwide rights cleared music. For music rights holders, Reactional enables music to become an in-game purchase for gamers and a music delivery platform for developers, while gamers can now personalize their gameplay by having their favorite music react to their actions and movements in the game.
