CDJ 3000: Thin red line below small waveform


I noticed on my CDJ 3000 there is a thin red line below the small waveform on the display. When loading a track, it is slowly progressing from left to right like a "load progress bar". Is the meaning of this somewhere mentioned in the manual? (I didn't find it)

However, it really looks like it is a load bar, as I cannot beat-jump further than this line/bar has already progressed.

So e.g., when I am loading a track with length of 8:00, this progress bar quickly goes up until about 2:30 and then slows down significantly, adapting to playback speed. So it will always keep the next 2:30 in memory.

But my understanding was, that the CDJ 3000 would load the complete track in memory? Or is this not the case?

Please clarify.

That's the buffer status line. As you note, you can't jump past it, but once the full track is loaded - yes, it's stored in memory and you could pull your drive and play out the entire song.

Yes, but my assumption was the CDJ 3000 would continue to load the whole track into memory, but it is stopping the loading after about 2:30 from current playhead position as described above.

However, as everything is working fine I don't care too much about this :-) It was just a question out of my curiosity. I mean obviously there must be a limit for the loading/buffering. E.g. if you have an uncompressed 60 minutes track, it wouldn't be possible to load the whole track into memory.
