Recently I got my hands on Mixed In Key version 5. I knew the program of course by name and also by fame, but I never had used it before. So I was kinda curious what it was all about. If you have never heart of Mixed In Key, it is an analysis program to detect information like the key and bpm of audio files. With this information DJs can elevate their mixes to higher levels because of 'harmonic mixing'. DJs can match tracks better or select tracks that are (more) compatible with eachother (key wise). If you need more information on harmonic mixing, checkout this page for a detailed description.
