OK, I think I figured this one out too.

I was making wav files from my Pro Tools rig, I would save the wav file, then copy them into the MiDJay. Everytine I went to play the file it would say corrupt file.

So I took that same file and converted it into a MP3 and the MiDJay would play it fine,

so now I took the original wav file from Pro Tools and using a conversion program, converted the wav into a wav again, and guess what it works on the midJay, I guess from pro tools there was either something missing or something added that made the midjay not read it, I will be using them as mp3's anyway, another question, what have you found to be the accepltable bit rate for the least amount of loss in audio?
