Firmware: 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
