Mixware Rapid Evolution is a free advanced harmonic music library tool for DJs, designed to be used while you mix.

Description:

Rapid Evolution helps profile your songs by saving important properties, such as the BPM, key, time signature, styles, comments, etc. You can then instantly see which songs are within BPM range, in key harmonically and in similar styles. More importantly, it lets you save comments and information about each individual mix you come up with.

Use it to enhance your knowledge of your music and remember the important details of what you do.

The software includes automatic BPM and key detection, as well as tools to determine this information yourself–a BPM tapper and a MIDI keyboard. It is designed for the power user, and offers extensive searching, filtering and browsing capabilities. You can create custom hierarchical styles to help organize your tunes. It also lets you share all song and mix information with other DJs.

If you are a software based DJ, you can take advantage of features like dragging and dropping the songs to play them. Otherwise the program can act as a reference or guide as you mix. If you don’t have a computer near your turntables, it is still useful for planning mix sets and finding compatible songs ahead of time.

See the Mixware site for  details.

About Harmonic Mixing

Harmonic mixing is the natural evolution after beat matching/mixing, consisting of mixing in compatible keys (notes). With the latest audio analysing software like Mixed in Key or using dedicated DJ mixing software with harmonic classification such as MixMeister, you can avoid sour mixes caused by clashing melodies, as the “master key note” is previewed on the track info.

When used properly, this info can help the DJ mix long overlays (on any DJ setup or software) without relying on percussion or “free beats”.

Key and Code classification facilitate choosing tracks for a set, if you’re interested in limiting your search to tracks in related keys and tempos.
