Endorsed by no less a DJing luminary than Pete Tong, Mixed In Key 4.0 provides an easy utility for accomplishing what was once considered an advanced DJ technique: harmonic mixing. Keeping harmonically-volatile tracks segregated is easier than ever before!

Even if you're as deaf as Frankie Wilde from It's All Gone Pete Tong you can still mix harmonically cohesive sets, and even create seamless mashups, using the straightforward and mostly automatic Mixed In Key application. Mixed In Key will scan your audio library and attach meta-data identifying each track's key. Then it organizes your tracks into harmonically-compatible order.

What makes a track harmonically compatible? Well, for those of you who've never encountered the circle of fifths (DJs), the Mixed In Key site has an example of the "Camelot Wheel," a chart that was "designed" to make harmonic mixing easier, and so named because "it's only a model":

Mixed In Key cuts out the need to memorize or even understand the Camelot Wheel by doing the harmonic planning for you. It's compatible with .WAV and .mp3 formats of all bitrates, and the generated, harmonically-sound playlists can be dragged and dropped into popular DJ programs like Ableton Live, M-Audio Torq, Native Instruments Traktor, Serato, Virtual DJ, etc.
