"Hi, Have you seen the announcement for Stems? ( http://www.stems-music.com/index.html )
"As an open multi-track audio format, Stems enhances creative possibilities for DJs, producers, and live performers. A Stem file contains a track split into four musical elements: A drums stem, a bassline stem, a melody stem, and a vocal stem for example." On the developer section ( http://www.stems-music.com/stems-is-for-developers/index.html ) there is a bit more information: "Stem files use the .mp4 container format to store the four individual stems of a track within a single file. Using the file extension .stem.mp4, this single file can be managed just like an mp3 file. A standard master version of the track is also included in the file and can even be played in stereo with any compatible audio player following standard mp4 specs, like iTunes for example. To play with a track’s individual stems, Stem-compatible software or hardware is required." Seems like a good move they didn't create a brand new container. Yet to see some files out in the wild. According to this article ( http://thenextweb.com/insider/2015/08/03/stems-a-new-open-file-format-for-djs-makes-mixing-easier-than-ever/ ) they are already sold on Beatport & Traxsource.
