Hi Donny,
I think the PA500 uses SD card not thumb drives??
Principle is similar, Doc, get Paula to save them to a PC then copy them to an sd card .
A lot of newer PC's have sd card slots inbuilt, if not, an inexpensive sd card reader would not go astray.
Also if you do buy an sd card, you don't need one with heaps of memory. Styles don't take up much space.

In my case with the PA800 I use thumb drives, I've got 3. I like to keep plenty of backups of my data, just in case a thumb drive gets faulty.
I used to do the same with my sd cards for my KN7000. A couple of cards at least for backup.

For the PA800 I can transfer styles etc directly to a PC via a USB cable. Same may go for the PA500? I find the portability of a usb thumb drive ( in your case an sd card) far easier.

best wishes
Rikki
