I am using a DDJ SX2, Macbook Pro and the Serato version is the 2.0.3

Have you tried setting the colors in the library tab? You can choose grey, blue of none.

Hello there, yes I have tried that as well. I have sent a request to Serato for help.The funny thing is that when I unplug the controller, the history shows up, only with the controller there is the issue.

I have the same controller, but I use Windows. I don't have this issue, but my setup is different. Hopefully, someone with a Mac and an SX2 can comment.

I have this issue now and then it could be just a bug or a UI issue, I noticed this bout 4 versions back I'm on a MB Pro with DDJSX2 but it doesn't bother me, you can open up a help request so serato can take a look at it-->support.serato.com

Very appreciated guys, I have solved the problem. I uninstalled and installed the app several times, then I opened it on player mode and it started working again (I have a suspicion that it has something to do with the MIDI mapping on the SX2, specifically with the use of "SHIFT") as it never happened before on my NV controller.

Now I have a different issue, I deleted my samples :O but that's another story, hahaha damn it.

Have a great day all!

I have bad news guys, it seems that when I restart serato it starts recording the played tracks (marking them blue) and everything is good until I double click the "SYNC" button, I am sure this is a bug that prevents from the app continuing to record the played track history. The only other way I know how to fix this is to re-start the app (which is a hideous workaround if you are already at the gig).

Hopefully serato can take care of this soon enough because its going on for weeks now.
