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.

When tested I noticed KeyFinder uses the Db notation instead of C#. I prefer the latter, therefore I have changed the preferences:
