xdi 1000 Big wave form not showing for long tracks ?

Hi, 

I have two XDJ 1000 and DJM 750.

-i properly updated software and firmware for both RB and XDJ1000 

-i transferred tracks into RB and Analyzed then exported to Two different USB sticks that are properly formatted

Can the XDJ 1000 show a waveform for  TRACK longer than 15 or 30 minutes ?
