DJ Tool
Beat Sync Trainer
Bring two beats together
The tool — try it now
Two decks play synthetic kicks: deck A holds 120 BPM, deck B starts audibly detuned. Pull the pitch fader until the galloping fades, then lay the hits on top of each other with the nudge keys — until two kicks become one. No hardware, no music files.
What you learn with it
What beatmatching IS before you practise it on gear: match the tempo, then the phase. You hear the difference between “almost the same speed” (galloping) and “locked” (a single hit) — exactly the ear DJing is about.
How to use the tool
Press start — deck A plays on the left, deck B on the right, audibly too fast or too slow
Pull the pitch fader until the galloping slows down and fades
The kicks are still offset: push deck B with earlier/later until they line up
Hold the lock for 8 beats — the display counts along
Press again: deck B is detuned anew, different every time
Listen to the rhythm of the DIFFERENCE, not the single hits: fast galloping means far off, slow galloping means almost there. When nothing sounds doubled any more, you have it.
Common mistakes
Nudging the phase while the tempos still differ. The most common wasted effort in beatmatching.
Listening to the individual beats rather than to the gap between them. The galloping is the information, not the beat.
Taking your hand away after the first match. Without correction it drifts apart again within half a minute.
15–30 minutes
Take the time in one go — hearing and timing develop through repetition, not through reading.
You have it when you can make the galloping disappear three times in a row — and then hear nothing doubled for half a minute.
Questions about this tool
What is this galloping I can hear?
Two beats arriving just after one another instead of together. The further apart the tempos, the faster the second beat travels — hence the impression of a gallop. Narrow the gap and the gallop slows. When it disappears the beats sit on top of each other and you hear only one.
Tempo first or phase first?
Always tempo first. Nudging the phase while the tempos still differ is futile — it drifts apart again immediately. Only once the galloping has stopped is it worth lining the beats up. Reverse that order and you work against yourself the whole time.
It fits briefly and then drifts apart again. Why?
Because of the tempo, not the phase. A tiny difference is inaudible in the moment and very audible after thirty seconds. That is exactly why a DJ keeps correcting — beatmatching is not a state you establish once but a movement you hold.
Why practise this when there is a sync button?
Because sync is only as good as the analysis behind it. With live playing, older recordings and anything with an uneven pulse it jumps — and then you need the ear you would otherwise never have trained. The second reason is more practical: on two turntables that button does not exist at all.
