Firmware release notes
Update the firmware
Axe-Fx II: Firmware update guide for Axe-Fx II. Including troubleshooting tips.
Always disconnect the MFC-101 when updating the firmware on the Axe-Fx II.
The firmware for the AX8 and FX8 includes a firmware update guide.
MFC-101: go to the MFC-101 page.
Boot recovery
Built-in backup firmware in the Axe-Fx II XL and XL+, FX8 and AX8 allows recovery in the event of complications during update.
- Axe-Fx II XL/XL+: hold down Page Left and Page Right while cycling power.
- FX8: hold down SETUP and power the unit on. Hold the button for about 1 second beyond the power up, then release. The unit will now allow you to install firmware using Fractal-Bot.
- AX8: hold down SHIFT and power the unit on. Hold the button for about 1 second beyond the power up, then release. The unit will now allow you to install firmware using Fractal-Bot.
If the Axe-Fx II or AX8 sounds bad after an update, try reinstalling the firmware, or perform a system reset.

More information
The Axe-Fx firmware is coded in C and assembly. source
Fractal Audio:
- "The Axe-Fx II can be reprogrammed at least 100,000 times." source
- "Most DSP compilers include library functions for common signal processing functions. However every library I've seen makes the same mistakes in several important and oft-used functions. I can't disclose what functions and what those mistakes are but because of this we use our own hand-coded assembly functions for our own libraries. The results are measurable and audible especially when dealing with the special requirements of amp modeling. I should add that these libraries are low-level functions like FFT() and such. You're not going to find a library that implements a Tube Screamer or even something more granular like a diode clipping circuit. That all has to be developed in-house." source
