Free key estimation software for DJs

Free key estimation software for DJs

KeyFinder is free open source key estimation software for DJs interested in harmonic and tonal mixing. This is defined by Wikipedia as:

a DJ‘s continuous mix between two pre-recorded tracks that are most often either in the same key, or their keys are relative or in a subdominant or dominant relationship with one another.

The primary goal of harmonic mixing is to create a smooth transition between songs. Songs in the same key do not generate a dissonant tone when mixed. This technique enables DJs to create a harmonious and consonant mashup with any music genre.

Primarily designed for electronic and dance music, it is highly configurable and applicable to many music genres.

Beatmatching tutorial

Beatmatching tutorial

When I started mixing, I realised that one of the most important skills is beatmatching. Of course it is possible to press the sync button every time, but learning by hearing seems to be useful. I found a well written tutorial which describes all the ins and outs of beatmatching.

Reloop Digital Jockey 2 midi layout overview

Reloop Digital Jockey 2 midi layout overview

Since a couple of weeks I am the owner of a Reloop digital jocky 2 controller edition. A nice digital MIDI mixer for beginners just lik me. When I connected the mixer to my Mac, it worked immediately with Traktor. Since some midi mappings did not worked out I decided to remap these functions.

Unfortunately, the Reloop digital jocky 2 manual did not have any MIDI map inside. I decided to spend a couple of hours to figure out the MIDI layout. There might be other people who would like to have the layout as well. You can download the MIDI layout in the PDF format, or from the images shown below.

If you notice any mistakes, please post them in the comments so I can update the MIDI layout files. I would like to thank Marthijn for checking the draft versions of the MIDI layout for any mistakes.
