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.
Accurate tempo and Camelot key detection across your whole library, no manual tagging.
Every track normalized to a consistent loudness target. Stop riding the trim knob mid-mix — no more surprise redlines or volume drops between tracks.
Intro, drop, and outro cues placed automatically based on the track's actual structure.
See structure at a glance — energy, breakdowns, and drops rendered before you press play.
Draft a key-compatible, energy-mapped track order straight from your tagged library. Built-in compatibility meter shows which tracks make the smoothest blends.
Import-ready output for Rekordbox, with more platform exports on the roadmap.
Full track analysis at a glance — BPM, Camelot key, energy, LUFS, gain correction, waveform, and vocal detection for every track in your library.
Build harmonically compatible sets with real-time compatibility scoring. Drag to reorder, filter by energy and subgenre, and save multiple set variations.
See your entire library mapped to the Camelot wheel — instantly find which keys you're heavy on and spot gaps in your collection.
Sort by recently added, name, BPM, key, or energy. Every track is analyzed the moment it hits your library.
Founding prices for the first 50 customers — locked in even after the app leaves beta.
Same tools, same results — except I run them. Send me your library and get it back sorted, or hand me a gig and get a full set built around it.
Send me your library. You get it back keyed, BPM-corrected, loudness-leveled, cue-pointed, deduplicated, and dead files removed — import-ready for your software. Plus a before/after report showing exactly what changed.
Got a slot that matters? I build the set around your library — harmonic key path, energy arc matched to your position on the lineup, transition technique for every pair, EQ and FX notes, timestamps. Delivered as an interactive guide you can pull up in the booth.
I built HARMØNi because I was the customer. A 3,000-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.
