Hi, I've had the XDJ-RX for a month now and it has been great so far. I've had the odd issue where emergency loops have initiated and also freezing but these are rare. Recently I have been having another issue which I am going to try and describe. I always analyse all my tracks in rekordbox before exporting to usb. In rekordbox I set a cue point at the first beat of the bar for almost all tunes in my library. Anyway when using the XDJ and pressing play on a track from said pre-set 1st cue point I strangely get audio from a different unselected track which is out of sync, and then the track which should be playing will then kick in after approx 3-5 secs? This doesn't happen on any particular track as I have noticed it happen on several. Tonight when it happened I had been mixing for approx 2 hours and when it happened I stopped the usb, turned unit off and back on, reloaded the track and it happened again? All my tracks are downloaded from beatport, and analysed using MP3 val with no issue. My usb has been formatted using the app you have recommended to others on the forum. I am using firmware 1.6 but this also happened in 1.5. I hope I have explained this properly, but if you require further please let me know and I will be happy to help. Cheers, Craig
