How can I fully erase and reset the internal SSD memory?
Do the following: Prepare six blank disks. No need to use already formatted disks. Go to Disk > Page 8 (“Utilities 1”). Select Save OS to make an OS disk. Insert a blank disk, and wait for the OS disk being created. When finished, remove the OS disk. Select “Backup Data” to save all your data in memory. Insert blank disks as requested by the Korg Pa50 MidEast. When finished backing up, remove the last backup disk, and insert the OS disk. Turn the instrument off, then on again. A message appears, asking you if you want to load the operating system. Press FADE IN/OUT to start SSD formatting instead. The SSD memory is completely “wiped out”, and the operating system automatically reloaded. When finished, remove the floppy disk, and press any button. Go to Disk > Page 8 (“Utilities 1”). Select “Restore Data” to reload previously backed up data.
