Find what mixes next.
Pick a track and see everything in your library that's in key with it.
Every track tagged and ready.
Key, BPM, energy and genre, filled in across your whole library. It keeps what you already have from Mixed In Key or Serato, and marks anything it had to guess.
See what else it does
What's in the crate.
One copy of every track.
Got the same song three times? It keeps the best one and puts the rest in the Trash, where you can still get them back.
Moved your music? We'll find it.
Switched drives or renamed a folder? Grooveprep finds your songs again, all at once.
Find out now, not in the booth.
Send your tracks to rekordbox, then check your USB stick. You'll know everything plays on your decks before you leave the house.
Checks your playlists
Paste a Spotify or YouTube Music link and see which songs you already have.
Catches key mix-ups
When two sources disagree on a track's key, it tells you.
Spots low-quality files
Some files say high quality but aren't. They go in their own list.
Every change has a way back.
Grooveprep never changes how your music sounds. Don't like a change? Hit Undo.
It won't touch rekordbox while it's open, and it saves a backup first.
