i backed up some loop samples before I moved and I recently tried to upload them into my MPC and it said bad format(405). I put the CD into my computer and saw that I accidently burned it as a data CD and I can't seem to find the original. Do any of you know how to convert the files to an audio format that will work for me? I'm not even sure if thats possible, but if anybody knows I will greatly appreciate it. thanks
