I don't have any user files to save yet. I did use the flash drive to update the firmware so in that application, the flash drive worked.
I tried accessing the new sound folders from Mike Martin and after the binding process, the display read "err no file fnd". I tried two different flash drives, both of them in the FAT32 format.
One is 16GB, the other 1GB. I even used the keyboard to format the 1GB and yes, the MUSICDAT file was installed when complete. Am I doing something wrong?
