Point CortexDJ at a folder of music you own. It analyzes key, BPM, energy and structure on your computer, picks and orders the tracks, beatmatches them and renders a finished set to WAV or FLAC. You can also play the set on the built-in decks and take over any control, or export it to rekordbox, Serato, VirtualDJ, Traktor, Engine DJ, Mixxx or djay. Your music is never uploaded, and it works with local files only, not streaming services.
