Reactional Composer
Reactional Composer is an authoring tool used for creating interactive music for games with Reactional’s own proprietary format, a Reactional Theme. As a core design principle, it is built to be used by composers and audio directors, and be as frictionless as possible. Therefore, you do not need to export your music or use any special plugins in your DAW. You simply create your music as you normally would with any VST3 plugins, and Composer will take care of the rest.
Drag and drop your DAW (currently supported DAWs: Reaper, Cubase, Studio One, Bitwig and Ableton) session into Composer, and it will automatically analyze your music and create a Reactional Theme. You can then preview your music in the built-in player, design your interactive music, and export it to your game.
