APU Harmonic DJ, from APU Software, is a set-planning tool for DJs who mix harmonically. Point it at a folder of your own tracks and it analyses each one for BPM, loudness and harmonic content — including separate key estimates for the start and end of a track, and the mode, not just major or minor. APU Harmonic DJ 1.3.4 for Mac then proposes directed tracklists that follow your tempo and transition rules, which you audition and judge by ear before ever opening your DJ software.

Key Features

  • Local analysis of BPM, integrated loudness and harmonic evidence for your whole library
  • Key detection across six modes — Ionian, Dorian, Phrygian, Lydian, Mixolydian and Aeolian
  • Tracklist generation with your own tempo behaviour, key scope and transition rules
  • Saved transitions, called Gems, that remember a direction that worked
  • Local-first design: audio is analysed on your Mac and is not uploaded

How to Download

  1. Download the free Community edition to analyse your library first.
  2. Get it from the developer: Download from the official site
  3. Install the matched standalone app and plug-ins together, add a folder of tracks, and let the analysis run.

System Requirements

Harmonic DJ needs macOS 10.14 or later on an Intel or Apple silicon Mac (a universal build), with OpenGL 3.2. It installs as a standalone app plus VST3, Audio Unit and AAX plug-ins, which must all be the same version.

FAQs

Is Harmonic DJ free?

The Community edition is free, needs no account, and includes the full analyser and editable tracklist previews of up to five tracks. Pro is a one-time paid licence that raises the track counts and adds Gem features.

Does it beatmatch or mix for me?

No. Beatmatching, cue points and the blend itself stay in your DJ software. Harmonic DJ plans which tracks follow each other well; you still perform the mix.
