Field notes
The beta is described as requiring an Apple-silicon Mac (M1 or newer); the page says songs stay on the Mac and Grooveprep will not touch rekordbox while it is open. It preserves existing Mixed In Key or Serato data, marks anything it guesses, and moves duplicate copies to Trash rather than deleting them outright. The page also describes a backup-first workflow with 30 days of undo, plus compatibility checks for named Pioneer decks, audio formats, and USB formatting.
