// WHAT IT DOES
SYNC is a button that automatically matches the BPM and phase of one deck to another.
Press it and the deck locks to the master deck's tempo and beat position instantly.
It's reliable when beat grids are accurate. It's wrong when grids are wrong.
Think of it like → Cruise control on a car. Great on a smooth highway, dangerous on a winding road. The road is your beat grid.

- • Frees your hands for EQ, effects, four-deck work.
- • Lets beginners focus on track selection and energy.
- • Standard in modern club DJing — using it is normal.

▸ Signal flow — watch the dot
▸ SIGNAL FLOW
Glowing dot = your signal travelling through Live.
▸ LISTEN FOR
- • Snap-to alignment when SYNC engages

- • Pitch jolt when master changes
▸ WALKTHROUGH (5 steps)
- 1. DO: Load a track with a clean grid to Deck 1 and play it.▸ LISTEN: Steady tempo — no .
- 2. DO: Load Deck 2 and press SYNC.▸ LISTEN: BPM display jumps to match Deck 1; tracks lock instantly.
- 3. DO: Cue Deck 2 and listen alongside Deck 1.▸ LISTEN: Kicks land together — verify, don't assume.
- 4. DO: Mid-blend, watch the grid markers — if they slip, the original analysis is bad.▸ LISTEN: Audible drift = grid problem, not SYNC failure.
- 5. DO: If drift starts, disengage SYNC and finish manually with the jog wheel.▸ LISTEN: Manual control restored; crisis avoided.
▸ COMMON MISTAKES
- ✗ Trusting SYNC on unanalysed or hastily-analysed tracks.
- ✗ Forgetting key-lock — high-tempo SYNC sounds like chipmunks.
- ✗ Never learning manual beatmatching as a fallback.
