Halo 4 Remix Contest - Stem Archive
In October 2012, 343 Industries held a contest where remixes of official Halo 4 tracks could win you cool prizes. They supplied the stems from 3 tracks from the Halo 4 soundtrack, you supplied the creativity. The contest is over, and the website still exists (as of this writing, in January 2013) - but the stems are no longer available for download.
That seems like a shame, so with the help of RC Master, we've got them here, for you. There are three tracks (Awakening, Nemesis, and To Galaxy) with six or seven stems for each track (plus instructions). The files are uncompressed .wav files, so they're somewhat large... so be gentle.
We're making them available in zipped folders - grab and enjoy!
