My CDJ 3000 dos not synchronise when looping !!!

Hi Everyone,

1. When I use loop stored in memory or an Active Loop the player which is playing loop dos not keep the tempo. Each loop it makes causes  millisecond loss so after a while I have to make correction with the jog . 

At this time the waveform on the display shakes  with each loop . 

Loops made during playing truck and not stored in memory works correct and the waveform is clean.   

2. When I use Inst. Doubles the truck loaded using this function buton is not synchronised with the Master player and the waveform shakes like on my mother’s old tv screen :) 

Could You please help me solve this problems ?   

 Greetings

Tom
