Today, Native Instruments officially launched its new multi-track audio format, Stems.

Stems is an open file format which gives DJs the ability to control a track’s four different musical elements—drums, bass, keys, and vocals, for example. Stems is also now compatible with Traktor’s software, and hardware, with the Traktor Pro 2.9 update.

Beatport, Bleep, Juno, Traxsource, whatpeopleplay, and Wasabeat are now selling Stems formatted tracks, with a free Stem Creator Tool following later in the year. Check out a video of Stems in action below.
