CortexDJ

CortexDJ is desktop software for making DJ sets from music you already own. It suits streamers and creators who need a continuous mix, party hosts who want a finished set without learning to beatmatch, and DJs who prepare in rekordbox or Serato. Choose a folder, and CortexDJ analyzes Camelot key, BPM, 1-10 energy and intro, drop and outro points on your own computer. In Simple mode you pick what to mix, a length of 15 to 120 minutes and the transition length, then press Make a mix. Advanced mode adds the full console. What it does today: - Builds beatmatched sets ordered by key and energy, and renders them to WAV or FLAC with a tracklist - Live decks with sync, EQ, filter, echo, loops, hot cues and auto-DJ - Mashup finder with AI stem separation - Export to rekordbox, Serato, VirtualDJ, Traktor, Engine DJ, Mixxx and djay - Reads MP3, FLAC, WAV, AIFF, M4A/AAC and OGG, including existing Mixed In Key tags It runs on Windows 10/11 and on Apple Silicon Macs with macOS 13 or later (beta). It works with local files only, not Spotify or other streaming services, and your music is never uploaded. The Free edition is for personal home use and is not a trial. Pro ($59 a year or $7.45 a month) and Lifetime ($127 once) add MIDI controllers, recording, live-streaming and use at public or paid events. You need the rights to any music you publish, stream or play in public.
