To turn Auto Play off in rekordbox, go to Preferences > Controller > Deck and disable Continuous Play / Auto Play ; also make sure Auto Cue is enabled if you want tracks to stop at the cue point instead of starting automatically when loaded.

What to check

  • In rekordbox, open Preferences.
  • Go to Controller.
  • Open Deck.
  • Turn Continuous Play off.
  • Enable Auto Cue for the decks you use.

Why it happens

If a track is already playing and you load another track onto that deck, rekordbox can keep playback going unless those settings are adjusted.

If it still auto-plays

  • Check whether Load Lock is off, because that can let tracks load into a playing deck.
  • On some Pioneer devices, Auto Play Mode can also be changed from the device menu by holding Menu and turning it off there.

Quick wording for your post

Quick Scoop: In rekordbox, go to Preferences > Controller > Deck, turn off Continuous Play , and make sure Auto Cue is enabled so loaded tracks don’t start on their own.
