XDJ 1000 MK2 - How to active a loop memorised?

save your loop as a "Hot Cue" then trigger it with the Hot Cue buttons (A, B, C, D)

I tried, but same problem, when i push the hot cue, the track directly jump to that point.
I just want to activate it, in order the loop can start when the track read it.

I'm not sure I fully understand you question?

To trigger a loop with a single XDJ button press: create using Rekordbox your loop and save it as a Hot Cue, remember the Hot Cue letter you saved it as, then when you play it back on an XDJ press the Hot Cue button for that loop (A, B, C or D) and it will play back that loop

If that is not what you are trying to do please explain what it is that you want to do?

You can also save a loop in Rekordbox as a Cue then set it as an "active loop" which means when the song reaches that Cue point it will automatically loop until you exit the loop

Hehe yes, no easy to explain with my english, sorry...
Yes, when I push the Hot Cue button (A, B, C...) the track directly go to the point and read it. I don't want this, I would like only activate the loop while pushing the button, the same than a active loop set in recordbox, but I would like to decide which loop I will activate or not while playing the track.
Am I more clear? :/

And second question, with recordbox only one "active loop" can be set for a track, right?

Thank you!

What you want is to set an ACTIVE LOOP into the memory; that will be triggered automatically as the playback reaches that point. You can only store one per track.

Hot Loops are your other option, as already noted above.
