Harmonic Mixing explained

How Mixed In Key can improve your Serato mixes

What is Harmonic Mixing?

Key-compatibility is the basis of harmonic mixing. You need to know that Track 1 is a musical match with Track 2. That might mean they’re both in the same key, or in different, complementary keys. If they’re not, they can be a key-clash, which will sound bad, and not in a bad-meaning-good way! We invented the technology that allows DJs to see whether their tracks are harmonically compatible at-a-glance, and have spent over 11 years perfecting it.

Why mix harmonically?

Whether blending whole tracks, samples, vocals, melodies or basslines, Harmonic Mixing will help you sound amazing. This simple technique unlocks a treasure chest of creative possibilities. You’ll have the key to flawless mixes, impeccable mash-ups and learn how to control the energy of your set in a myriad of new ways.

Our market-leading software scans your collection and matches the results to our groundbreaking Camelot EasyMix system. It tells you what key your song or sample is in, and what will mix best with it. You don’t need an understanding of keys or music theory… it’s as easy as 1, 2, 3

8 Cue Points made for you

Every track you analyse in Mixed In Key will get 8 cue points. Our amazing waveform analyzer automatically plots them at the most important parts of the track. It’s the fastest and most accurate way of adding cue points to your Serato crates.

Make Smart Crates in Serato based on Energy & Key.

Take greater control of your Serato crates by creating targeted smart crates with Mixed In Key.

Find the perfect track, faster. Set your smart crates to sort by key and energy level. You’ll find the perfect cut for your next mix in no time. It’s the surest way to keep the right vibe going all night.

Nicole Moudaber

“Since I play with 4 decks simultaneously, I find Mixed In Key very useful especially when I play melodic and vocal tracks. Layering different drums, melodic riffs and vocals, the outcome is seamless and sounds so good with the dj style I’m into which is blending tracks, creating a continuous flow along the way”


“Mixed In Key is a huge time saver! I use it for all my DJ mixes these days.”


“I love Mixed In Key for its simplicity and functionality. I always use it before I add a new song to my set to make sure I know which key it is in.”
