Hey there,
I have an XDJ-RX and I've been having a lot of problems with it. It loves to just hang randomly at times with the "loading" circle and sit there for half of a song while I am in the mix. This is becoming extremely aggravating for a piece of equipment that was sold to me as "professional" quality.
I have had this issue across multiple thumb drives, and have taken the steps necessary to alleviate the issue, however the problem persists. I have taken my thumb drives and performed a full format, FAT32, two times sequencially to make sure they are formatted properly. I have also scanned all of my MP3 files and and fixed any files with errors on them. Even with that, I STILL get hang ups and it's really disappointing. I always write down which 2 songs were playing when the hangup occurred, and it is never the same songs involved.
At the moment I am using a 64GB Samsung Fit flashdrive, loaded in the USB2 port, to play and record simultaneously. I only have about 2-3GB of music on the drive. The errors also occurred on my 32GB Kingston DataTraveler drive when I was using that.
The hanging "load" screen is a problem that I can deal with (although I shouldn't have to) as the system usually unlocks in a few minutes and I can carry on, but what happens is when I playback my MIX RECORDING the audio gets messed up during the time that the system was hanging. For instance, when I am playing I'll have song A playing, transition smoothly into song B, and then the system hangs while I'm trying to browse for song C. Once I do load song C, I perform another smooth transition into it and so on.
The resulting recording SHOULD be my mix from song A, to B, to C, but it's not! When I review the recorded mix, I hear song A playing, and then it suddenly cuts to song B without any transition, just a hard cut at some random point in both songs. Song B will play for 30 seconds or whatever, and suddenly cut back to a cue point and continue playing for another 30 seconds, cut back to the cue point AGAIN, and then carry on as normal and I hear my transition from song B to song C as I played it.
This is beyond bizzare and it completely ruins the flow of my recorded sets. Please help me get to the bottom of this.
EDIT: I'm also using the latest firmware.
