5. In Setup Menu of M9 (Press the 3A and TAP buttons at once, then press the MODEL SELECT knob 3 times until the display shows MIDI in the top left) or the M13 (hold the 'Looper Controls' button), select 'Dump All' to backup all your scenes, 'Dump Folder' to backup the current folder, or 'Dump Edit' to backup the one scene you have currently selected. Press the TAP button and the 'MODEL SELECT' knob at the same time on the M9 or just press the 'MODEL SELECT' knob on the M13 to begin the dump. Click 'Done' in MIDI OX when complete.
