DJing is like playing an instrument, but the notes are actual tracks, and the song is your set. Music has a natural affinity to influence our mood, and different sounds will evoke different emotions. Music also affects our energy levels, sound is a force and can be manipulated to change energies. This is where Mixing In Key comes in, mood and energy.
Mixing In Key (MIK) essentially analyses your tracks by key and energy levels. Using the theory of the Camelot Wheel, MIK establishes connections to your tracks to help you develop a musically cohesive set list; one that builds in energy levels and is in harmony with the rest of the tracks. It’s like playing a real instrument, different combinations of notes and chords create different moods and energies.
Mixing In Key’s name comes from the actual practice of ‘mixing in key’. Each track is made in a certain key e.g. G Major or A Minor. For example, Disclosure’s track “Latch” is in the key of Bb Minor or “Bbm”. Putting Bbm on the Camelot Wheel gets you a value of 3A. Using the rules of harmonic mixing, a compatible song could be 2A (Ebm), 4A (Fm) or 3B (Db). As you can tell, the basic rules is that if you have a track in a certain key, you can go up or down the corresponding wheel, or immediately across on the adjacent wheel.
Harmonic mixing was discovered in 1986 by Stuart Soroka, and enabled DJs to make smoother transition between songs, also without the risk of tracks clashing sonically. It opened up a whole new world of mixing, and creating a harmonic and energetic atmosphere. All the professional DJs today realise this, and even endorse the use of MIK, the program and practice. Just look at Kaskade, David Guetta, Diplo, Steve Aoki and more.
There are various substitutes for MIK the program. The primary one is called Keyfinder. It is free (but you can donate), however support for Windows has ceased. Keyfinder is easy to use and very efficient, however it can yield different results to MIK. Other competitors are actually the in house key analysis of Serato, Rekordbox and Traktor. They are fairly accurate but do not have the functionality of MIK yet.
If you want MIK for different OS, you will need to purchase them separately. However, if you would like to swap your OS using the same MIK, it is a simple email away, with a responsive reply time. Updates also cost money, but not as much if you already have an existing MIK program.
