Rekordbox analysis - beat slicer - Link

Hi,

I have upgraded to the performance pack and i am using it to play straight from my pc into my djm 2000n and cdi 2000n.  I am having problems with the quality of the analysis and most songs that i due to sink are off.  This was not the case in the previous version and i had faith in  the software, however now I'm sceptical as to gigging with it in a few weeks.  Now the quality of pioneer is so high I'm thinking i am doing something wrong and not the software........

1.Is there any methods i can imply to receive better, more accurate beat grids?

2. i have mentioned in a previous post about the link button on the computer missing in the new rekordbox version,  however when i swap to export mode my cdi, dam icon appear and i can send audio straight to the djm/cdj via drag and drop.........this is no the case in performance mode.  they disappear so i can't load into the djms memory or drag to a player.

3.  When hitting on on the beatslicer and whilst using the master sync, channel sync or mixer sync the 4 or 8 beat sample stays in time for a few seconds then tails off in to a horrid mashup.  the only way i can get it to sync is if i input the bpm on the touch screen before hitting on.  This takes more time and catching a sample on the fly is less spontaneous.

I would appreciate any help as I'm finding myself more and more resorting to my Traktor s4 because it has never had any issues.  

I want to use my pioneer setup foremost.

Kind regards

jay
