UPDATE: I managed to get it to work by deleting the midi device from the MACs audio midi device setup in applications and i unplugged and plugged it back in and it recognised it as the DDJ-RZ instead of USB Device.
Followed the steps from here: http://faq.pioneerdj.com/product.php?c=649&lang=en&p=DDJ-RZ&t=faq
I am now trying to get it to work on my friends laptop and failing at it miserably. I'm trying to replicate whatever I did including resetting the computer after uninstalling the audio drivers but the computer still just recognises it as a USB MIDI Device instead of the DDJ-RZ.
Any input would be appreciated.
