I’ve a system one. Playing with stand alone off a usb and I’m Getting BPM drift like You would With Serato on tech 12’s
Are you referring to sticker drift?
Sticker Drift: Platter position starts to differ from its original starting position compared to the start position of the sample.
BPM Drift: the BPM changes slightly while the turntable plays for an extended period of time without the pitch fader being moved.
Yes it is due to bpm which is xxx.x instead of xxx.xx on Engine devices
you need to turn on Sync button to maintain sync between two tracks on a long time

This isn’t the issue.
Drift, even on digital audio players, is inevitable over time unless you use sync. Even if you play the same track on two different digital devices are the same model and same OS versions, they will drift out of sync due to tiny differences in the devices clocks.
It’s part of why sync was invented.
I have four Black Magic 6K cameras and they ALL drifted out of sync over time. And these are cameras, not audio players. The solution? Introduce sync via a timecode device. These work similarly to a DJ sync tool as they synchronize each camera’s shutter so that the cameras don’t drift.

Don’t have these problems on pioneer devices for example
Shouldn’t an all in 1 device by using the same clock for both decks ? While I don’t disagree that no two digital devices clocks run identical, I think you’re overplaying the differences. It was not hard to have 2 separate CDJ’s running in sync for extended periods.
An AIO device is using the same clock.
The same song on two decks should not drift without sync.
Two songs with identical BPMs probably will.
