The original title is: "Mixed In Key vs Rekordbox vs Serato: Why DJ Platforms Disagree on Key 60% of the Time"

Short summary

Three professional DJ platforms — Mixed In Key, Rekordbox, and Serato — disagree on musical key detection for about 61% of tracks, with only ~39% full agreement. The article explains the technical causes: different chromagram algorithms, frame sizes, reference templates, and the fundamental ambiguity of relative major/minor keys. Practical advice: pick one tool and trust it end-to-end, since cross-platform mixing produces inconsistent harmonic results.

• •Mixed In Key, Rekordbox, and Serato agree on key only ~39% of the time
• •Disagreements stem from different algorithms, templates, and relative major/minor ambiguity
• •~70% of disagreements are relative-key flips (same Camelot number, different letter)
