How to update the Korg Nautilus 61 AT

Download the NAUTILUS AT System Updater zip from Korg and unzip it. Copy the update files and sub-folders (not the enclosing folder) to the root of a FAT32-formatted USB drive. Disconnect all other USB devices from the NAUTILUS, press GLOBAL and go to the Basic Setup page, choose Update System Software from the page menu, connect the USB drive when prompted and press OK. Do not touch the controls or switch the instrument off during the update. When the completion message appears, turn it off, remove the USB drive, wait about ten seconds and turn it on again; the startup screen shows the new system version.

Just for reference. For complete and up-to-date instructions, always refer to the manufacturer's official firmware page.
