Hi I am new to this , just got it a DP03. Simple question I think. I can't find the answer in the user manual. I mixed down my track, I mastered it. I burned it to CD. Fine, but now I am unhappy with some aspects of the mix. I wanted to take another crack at it. I loaded the track went back into Mixdown mode and followed the same steps. and now the mix isn't locked, not the new mix or the first attempt. And no matter what I do, it is now just mix it on the fly, no way to finalize it or record the end result to CD. Is That it? You get One shot? I didn't "protect it" Is that it? It can't be. Once you complete the Process once you can't do it again?
