Selectah

Selectah reads a folder of music the way a DJ reads a crate.

It measures the tempo, musical key, energy and genre of every file, shows you which tracks mix together and why, and lays out exactly how it would sort them — before it touches a single file.

WHAT IT READS

Tempo, to a tenth of a BPM. Musical key on the Camelot wheel every DJ already reads. A 1-10 energy rating. And the genre, from the tag when there is one.

When a file already carries a tempo and key from Rekordbox, Serato, Mixed In Key or Beatport, Selectah believes them and does not re-analyse. That turns a re-scan of a tagged crate from minutes into seconds. When a file has none, it listens to the audio and works them out.

WHAT MIXES WITH WHAT

Pick a track and Selectah ranks the rest of the crate against it, on the wheel and on tempo, and tells you why each one works: same key, wheel neighbour, relative major, the energy boost. Click any of them to hear it.

ELEVEN WAYS TO LAY OUT A CRATE

By genre family, subgenre, tempo, key, energy, year or artist. By genre and tempo together, or genre and key. As mixable sets, where Selectah walks the crate looking for runs in which each record leads into the next. Or as one long set.

NOTHING IS WRITTEN UNTIL YOU SAY SO

Every arrangement is a preview first: the folders it would make, and what would land in each one. Close it and nothing has changed on disk.
