Offbeat or Laggy hotcues during mixes.

I’m new to the Rekordbox, and I’m facing problem I never had with Traktor. Pressing Rekordbox hotcues is not reliable with sync, and a big gamble during a mix. Traktor’s quantize feature meant that even if you were slightly off-time when you pressed a hotcue during a mix, it would still snap to the beat and keep perfect sync. 

So, during a long Traktor crossfade mix, I could easily jump to an emptier section of the outgoing song while the incoming song was building up.  When I do this in Rekordbox, I’m often getting trainwrecks, flams and shuffles.  Pre-mix cueing of songs often needs a few attempts to get it right.  I often have to nudge the track with the jogs like I did in the vinyl days.  Or be quite careful when I press the key. 

I thought it might be related to a laggy laptop, but when I toggle the deck’s quantize mode (pressing the red Q key) the cue playback is instant. 

 I’ve also noticed that when I press the hotcue poorly, the sync button on the DDJ-SR will flash, and pressing it again will make it snap into place (if it isn’t too far off-sync).  I don’t think I should have to press two buttons. 

Sometimes there’s a long lag that maintains sync, but makes the phrase sound funny.  This seems to be related to the Quantize Beat Value preference settings, but I can’t really tell.  That preference seems to control snapping values when setting cues. 

I hope this can be fixed with my settings, and is some sort of teething problem as I switch systems. I like Rekordbox a lot so far. 

My setup: A Pioneer DDJ-SR with MacBook Air.  Rekordbox v.4.5.0 OSX High Sierra 10.13.4.
