A software function that automatically matches BPM and beatgrid phase of an incoming track to the master deck.
Sync is a software function that automatically aligns the BPM and beatgrid phase of an incoming track to the master deck, locking beats together without manual pitch adjustment. It depends on accurate beatgrids to work correctly.
Why it matters
Sync removes the mechanical task of tempo matching, freeing attention for track selection, EQ, and effects. Its reliability is only as good as the beatgrid underneath it, so incorrect grids will still produce a trainwreck even with sync active.
In practice
Before relying on sync, confirm the beatgrid is locked to the kick on both tracks. On tracks with live drumming or variable tempo, disable sync and use pitch bend to nudge manually.
