Backup and restore presets, cabs and system

The recommended way to save data from various Fractal Audio products: use Fractal-Bot.

Depending on the product, a backup can include system data, presets and user cabs.

Fractal Audio's software editors can also be used to export presets and cabs.

Another method to save presets etc. is to use a generic MIDI librarian, such as MIDI-OX (Windows) or Snoize (Mac), and dump the data from the unit using MIDI or MIDI-over-USB.

Axe-Fx III

Use Fractal-Bot to back up system data, presets and user cabs.

The Axe-Fx III can store a backup of the system data internally.

Axe-Fx II

Use Fractal-Bot to back up system data, presets and user cabs.

If you use Global Blocks in your presets, DO NOT FORGET to always backup the System data area. A backup of your presets alone does not contain the global block data.

"The XL does not have a backup to FLASH function because the presets are all in FLASH. If the battery dies you don't lose your presets so there is no need to back them up. The system data IS battery-backed and the backup function saves system data to FLASH." source

User cabs:

Want to speed up the backup process? Scroll to an empty preset slot before performing the backup.

The Axe-Fx II in USB Adapter Mode can be used as an interface, MIDI cables and a power supply are still required. Follow the instructions in Fractal-Bot.

The Axe-Fx III does not support USB Adapter Mode.

Save and load presets and cabs with the editor

The Preset Manager and the Cab Manager in the software editors can be used for bulk export and import of presets and cabs.


Browse doesn't work

If the Browse button doesn't work, exit Fractal-Bot, delete the file "Fractal-Bot.settings" and restart.

Empty presets after updating

If the preset banks show up empty after updating with Fractal-Bot, install the latest firmware first. Old firmware (even minor versions) may not always be able to read newer preset revisions.
