Cloning is no longer necessary. The mastered stereo track is available on the SD card as a standalone wav file. To bring it back to an empty stereo track, you'd have to copy it to the Audio Depot folder and import from there. Correct: can't be done without a computer. The good news is you don't need to mess with a USB connection. Just pop the SD card out and plug it into your computer. Just don't mess with any files other than the master or Audio Depot files. Changing recorded tracks directly can result in the DP24 freezing up. I know, I tried it. - Bill
