Pioneer XDJ 1000's m4a not playing

[jimmyv]

I recently bought 2 Pioneer XDJ 1000's to use with Traktor. It works great with Traktor.
I am having a problem using them with my music on USB drives. I am having a problem specifically with m4a files. These are songs that are purchased and downloaded from Promo Only.

A few details about my gear:
XDJ's are updated to the latest firmware
MacBook Pro OSX 10.9.4
iTunes version 11.4
mp3's are usually 320 kbps some 192, but they are ok
m4a are 1411 kbps

I drag and drop on my usb drive, eject from my computer plug it into the XDJ. It will play everything except my Promo Only music.

What am I doing wrong here?

Pioneer players don't support loseless m4a files.

Recode them into a playable format (AAC 320kbps?)

That sucks... I guess I won't be using USB sticks.

I have an 8000 song library on my computer and another 20,000 + on a hard drive... there is no way I am re-encoding them. Plus I don't want to lose the sound quality. yes, I can tell the difference and yes I have a very high end sound system that you can hear the difference.

offtopic: why?

ontopic: majority of dj's i know tend to use usb sticks only when playing out in clubs, i suspect you will also. when you do - make your playlist(s) in traktor, export it by copying files into a separate folder and re-encode just that files. that's what I would do.

or as you said - just bring the laptop with traktor and use it with HID mode on players, what's ever easier for you

I'm a mobile DJ, so I am always out with my laptop and controller (kontrol s4) now xdj's. Any bar or club that I do, I bring the S4.

One of the main reasons why I never used Rekordbox or been tempted to move to CDJs. (No lossless support... I've been a Promo Only subscriber for almost 20 years)
The new CDJ 2000 NXS2 supports flac and apple lossless (as does the new Rekordbox)...
I would think Pioneer should send an upgrade to your decks before long because they are fairly new.
At least that would make sense

Rekordbox has supported both AIFF and WAV since day one which are both industry standard lossless formats.
