Fractal-Bot is a simple and free utility, created by Fractal Audio, that lets you easily transfer data to and from your Fractal Audio device. It's not an editor.
You can use Fractal-Bot to:
- upgrade the firmware of the processor or foot controller
- send and retrieve single presets or preset banks
- send and retrieve single cabs or cab banks
- send and retrieve system data
- create and restore backups of all system data
- fix a "bricked" device

Axe-Fx II — USB or MIDI. You can use the Axe-Fx II as a MIDI interface
FX8 — USB. No driver required
AX8 — USB. No driver required
MFC-101 — MIDI. Use a MIDI interface or use the Axe-Fx II's USB Adapter Mode

Fractal-Bot checks for updates itself and will notify you if an update is available.
Using Fractal-Bot to update firmware
Read this: Firmware
In some cases, Fractal-Bot needs to operate in a special mode.
- hold CTRL (Windows) or COMMAND (Mac), and:
- click "Select Device" to reveal and select the hidden “Utility” menu option
- select the output port
- a MIDI Buffer Delay will appear, set it to 300 ms
This mode is used, for example, to update the low-level USB firmware of the Axe-Fx III (not the main DSP firmware) and the low-level firmware of the FC controllers.
Save and restore presets and user cabs, and create a backup of the System, including Global Blocks and FC Controllers configuration.
Save and restore presets and user cabs, and create a backup of the System, including FC Controllers configuration.
Save and restore presets and user cabs, and create a backup of system data, including Global Blocks.
If you use Global Blocks in your presets, DO NOT FORGET to always backup the System data area as well. A backup of your presets alone does not contain the Global Block data.
Axe-Fx II Mk I or Mk II – You can also backup banks of presets and system data to onboard memory. You can restore a single preset from onboard memory or the onboard factory presets using “Fetch” in the Utility menu
XL and XL+ – Saving presets to onboard memory is not possible, but a backup of system data can be stored in onboard memory
"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
Axe-Fx II Mk I and Mk II – User cabs 0-49 are included in a system backup. Cabs 50 and up are saved in a different area of memory and are not saved or restored when doing a system dump/restore, use Fractal-Bot to save these separately
Axe-Fx II XL and XL+ – User cabs are not included in a system backup. Use Fractal-Bot to back these up
Want to speed up the backup process? Scroll to an empty preset slot before performing the backup.
Save and restore presets and user cabs.
Save and restore presets.
Save the FC configuration data by saving the system data of Axe-Fx III.
Save and restore the MFC-101 configuration. This requires the use of a USB-to-MIDI-interface. 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.
Don't run Fractal-Bot and an editor simultaneously
Don't run Fractal-Bot and a software editor at the same time because this may cause conflicts.
If the Browse button doesn't work, exit Fractal-Bot, delete the file "Fractal-Bot.settings" and restart.
- Try another USB cable
- Do not use cable extenders or USB hubs
- Try another USB port on the computer
- Check for corrupt IRs or presets. Even empty slots may be corrupt (clear them using the software editor)
- Adjust the MIDI Buffer Delay
