Hi @mira99g2,

Here is some information on how the Master Deck is automatically determined in djay. In basic terms, the Master Deck is determined by the Deck that is actively playing through the master output (ex. Channel Fader and Crossfader open). I’ll explain with 3 common scenarios:

SCENARIO 1: No Decks Playing

  1. With Sync OFF and 2 new tracks loaded into Deck 1 and Deck 2.
  2. The Deck that you press the Sync button ON becomes the Slave and the other becomes the Master.
  3. For example, if you press Sync on Deck 1, Deck 2 becomes the Master Deck.

SCENARIO 2: Two Decks Playing

  1. This is basically the same a Scenario 1, but with the both Decks already playing.
  2. With Sync OFF and 2 new tracks loaded and Playing on Deck 1 and Deck 2.
  3. The Deck that you press the Sync button ON becomes the Slave and the other becomes the Master.

SCENARIO 3: One Deck Playing

  1. By default, the actively playing Deck is the Master. So the Deck that is Playing through the master output and the audience can hear (ex. Channel Fader and Crossfader Open).
  2. Pressing Play and the Sync Button on either Deck 1 or Deck 2 will Sync it to the one that was Playing first. For example, Deck 1 is playing through the main speakers and Deck 2 is paused with a new track. If you press Sync on Deck 1 or on Deck 2, Deck 2 will Sync to Deck 1 because it’s already playing and is considered the Master Deck.
  3. The first Deck remains the Master Deck until you stop playback and load another track onto that Deck.
  4. In this case, the other Deck that is now actively Playing with the Channel Fader Open and Crossfader side Open becomes the new Master Deck.

Also, please refer to the linked article below for more details on how Sync in djay works:

it’s a good idea to add a wizard designation
