HARMØNi — Build, Organize, Maintain
Desktop app · Mac & Windows

Every track.
Keyed, leveled, cued,
ready.

HARMØNi analyzes and preps your entire DJ library — BPM, key, loudness, cue points, dead files — so you spend your time mixing, not maintaining a spreadsheet of tracks.

Built by a working DnB/Neurofunk DJ — tested on a 2,800-track library, not a demo folder

Why this exists

I built HARMØNi because I was the customer. A 2,800-track Neurofunk and DnB library, dead files piling up, cue points I never got around to setting, volume jumps I'd hear live and wince at.

Every feature in here exists because I needed it for my own sets, not because it looked good on a roadmap. It's still evolving — fast — and founding customers get a direct line to shape what's next.
