DDJ-1000 Beat sync MASTER switches

I'm sorry, I don't understand the question?

Automatic switch sync Master...

CDJ's menu to see if there is some sort of setting to enable/disable the automatic master/slave change.... and DDJ? No disable switch

Press the sync button once to disable sync.

yes I know that...
I need this:
When I move from track1 to track2 and have sync beat (DECK1 is SYNC MASTER and DECK2 is sync only) and simultaneously changing the speed of both, SYNC MASTER and SYNC automatically switch. I want to use sync but not to change the master deck during play

Sorry for english is from googlu ... :)

I do not want it to switch itself, but it was synchronic

sometimes it happens to me that there are two tracks in the loop, and when I leave the loop, my track will jump and the synchronic is no OK

The master deck switches based on several criteria in order to assist you through mix transitions and changing decks back and forth.

If your decks are in sync and looping, they should remain in sync even after exiting.

And what are the criteria for switching?

Sometimes the switch is inappropriate. For example, when I call the jog speed ...

It would be good to turn off this feature ...:) ...
Maybe in the new version of the software ... :)
