I have a pair of the CDJ2000nx2 which have been brilliant since they first came out. I always ran the two players linked with player 2 using the link to player one, sharing tracks from player 1. The tracks were just in a simple format, not even rekordbox.
Around 8 months ago I started to notice that my player would randomly freeze up on tracks which have previously played perfectly fine. I have since upgraded the firmware on the players, re-done a pair of identical memory sticks purchased as FAT32, (32Gb) and every track has been analysed on rekordbox.
Here is the problem, again tracks on BOTH the sticks play on the players, but occasionally when I'm mixing and busy with the decks, I go to load a track on the player and it wont load, this then after 10 seconds sends the other deck into emergency loop. Then I have two decks which are both frozen on me.
I don't believe its the USB as I use to run the decks linked for many years, but im really confused about this. The decks have always been in a coffin case, never constantly plugged in and out so I cannot see the cable being an issue. For the record thou I have changed the link cable.
I really don't know why after all these years they are now starting to play me up, but its getting to the point where I don't feel they are reliable and I just don't know what else to do.
