Abstract: A file creation process, file format and playback device are provided that enables an interactive and if desired collaborative music playback experience for the user(s) by combining or retro-fitting an ‘original song’ with a MIDI time grid, the MIDI score of the song and other data in a synchronized fashion. The invention enables a music interaction platform that requires a small amount of time to learn and very little skill, knowledge or talent to use and is designed to bring ‘mixing music’ to the average person. The premiere capability that the file format provides, is the capability for any two bars, multiples of bars or pre-designated ‘parts’ from any two songs to be mixed in both tempo and bar by bar synchronization in a non-linear drag and drop fashion (and therefore almost instantaneously). The file format provides many further interaction capabilities however such a remixing MIDI tracks from the original song back in with the song.
