Is Using Sync Cheating? What It Does and When It Fails
No, using the sync button isn't cheating. It's a tool, and many DJs use it. The risk is leaning on it before you can hear a mix. Sync fails when a track has a wrong beat grid or a drifting tempo. Then your ears must take over.
What sync does
Sync does three jobs for you:
It matches the tempo. The new track plays at the same speed as the one already playing.
It lines up the beats. The drums of both tracks hit at the same moment.
It keeps them together. You don't have to nudge the track when it drifts.
In most systems, you choose how much sync does. You can let it match the tempo and line up the beats yourself. Some systems also line up bars and whole phrases. Check the settings in your own software.
The case for using sync
Mixcloud's editorial team made this case in March 2026. Sync frees you to think about track choice, phrasing, loops, effects and energy. It also lowers the barrier for beginners.
The article says sync helps most in a few cases. You might run three or four decks at once. You might play live mashups, or a fast set with many quick transitions. It also suits open-format sets and the long blends of house and techno.
The case against it
Manual beatmatching trains your ear. You hear small tempo gaps and feel the groove. Phil Morse of Digital DJ Tips coined the term select-sync DJing. It describes DJs who spend the set hunting for the next track and then press sync.
His point is that sync can hide weak mixing. A DJ glued to the screen also looks disconnected from the room.
When sync fails
Sync trusts the analysis your software made when you imported the track. If that analysis is wrong, sync makes the mix worse. These are the usual causes:
A wrong BPM. The software guesses the tempo incorrectly.
A tempo that changes. Some tracks speed up or slow down as they play.
A misplaced beat grid. The BPM is right, but the software puts the first beat or the bars in the wrong place.
Older records and live recordings. A live drummer doesn't sit on a perfect digital grid.
In these cases the software thinks it's helping. It's actually causing the problem. If you never learned to beatmatch by ear, you have no way out. That's the best reason to learn both.
How to check a beat grid
Most DJ software lets you view and fix the beat grid of a track. The buttons differ between programs, but the steps stay the same.
Load the track and play the start. Check that the grid lines sit on the kick drum hits.
Skip to the middle and then the end. A grid that's right at the start can drift by the end.
If the grid is off, move the first beat marker or analyze the track again.
If the BPM is wrong, set it by tapping along to the beat.
Save a hot cue on the first beat, so you can find your mix point fast.
A correct grid is what makes sync dependable. Do this check at home, and never in the booth.
A fair rule: learn both, then choose
Here's our view. Learn to beatmatch by ear first, and then use sync as a tool. Our guide on how to beatmatch by ear has a practice routine. After that, sync is a choice and not a crutch.
Try this drill. Mix two songs with sync off, then mix the same songs with sync on. In the first mix, listen for drift. In the second, listen for mistakes the software made. You'll learn what sync does well and where it fails.
Once the blend works, the next skill is the exit. Our post on DJ transitions covers five you can learn first.
Our Online DJ Classes teach beatmatching by ear and the beat-sync button in separate modules. Classes are live and one to one on Zoom, so a tutor can hear your mix and give you feedback.
Frequently asked questions
Do pro DJs use the sync button?
Some do. Mixcloud's 2026 article says sync suits open-format sets and fast-paced mixes. Other DJs prefer to mix by hand for the feel. Both groups exist.
Is sync the same as beatmatching?
Sync does the beatmatching for you. Beatmatching by ear is the manual skill behind it.
Can sync hurt my skills?
It can, if you never practice without it. You may stop listening for drift. Set aside time to practice with sync off.
What if the gear has no sync button?
Then you must beatmatch by ear. Turntables have no sync, and some older digital decks don't either. Ask about the gear before a gig.
