There are a couple more questions that might help us understand your problem, Scott. You said "it seemed a good way to save all panel memories instead of saving them on the SD card". What do you think is saved when you do the custom panel save?

Where is the file that contains the 14 songs? If the songs are in SD memory, why do you want to avoid using the SD card for Panel Memory setups?

After you pressed the Custom Panel button to retrieve the Custom Panel setup that you had saved, did you press any of the Panel Memory buttons?

When you corrected the 14 songs did you save them back to the SD card? If so, did you save the Panel Memory also?
