Beat sync between two computers

On one computer, sync is the easy case: both records play from the same machine. With a friend on another computer, each of you plays your own decks in your own place, and their sound has to cross the internet to reach you. Here's what sync feels like in Mix//Sync when the two of you are apart.

Whose beat is the beat

The deck that sets the tempo is the master. Press SYNC and your deck takes the master's tempo and comes in beat-locked. While it's synced, it follows the master's tempo, even when the master changes. To speed the mix up or slow it down, change the master.

Staying together

Once a deck is locked, it stays locked. It holds there without jumping the record back into place.

Hearing it together

You hear your partner's decks live, and their record and yours line up in your ears, so a blend between the two of you is a real blend. More on why mixing over the internet is hard: Why remote DJing has latency.

What stays with you

Sync lines up beats, not bars. Which phrase you bring the next record in on is your call. Sync also depends on each record's beat grid, the map of where its beats fall, so a grid that's off makes a synced record land off the kick. If that happens, fix the grid on the deck: see Fix a beat grid.

Mixing alone

Everything above that isn't about the network works the same on one computer. Press SYNC and the deck takes the tempo of the record that's playing and comes in beat-locked, whether your friend is in the session or not.
