It's a chore, but necessary to take advantage of improvements.įractal Audio regularly posts beta versions of new firmware and drivers on the user forum. If the new firmware includes major changes to the modeling, re-selecting every amp type in your presets is recommended, as will be stated in the release notes.In such cases the release notes will tell you to "deselect-and-reselect" a specific amp type in existing presets (aka a "soft reset"). Sometimes the firmware itself can't (or won't) enforce fixes or improvements and leaves it to the user to implement these.As a user you DO NOT need to do anything, UNLESS the firmware release notes instruct otherwise. If new firmware includes changes in amp modeling, these are often implemented under the hood.Read the firmware release notes and verify your presets. Updated firmware may cause changes in your presets. If this is the case, the firmware release notes say so and provide the link.Īudition presets after updating the firmware That's when the editor itself needs to be updated. Refreshing the effect definitions doesn't always suffice. Note: the editor doesn't refresh the definitions automatically after installing beta versions of firmware. If the editor doesn't do automatically (it should), force the editor to do this through the menu command. This means that the editor must retrieve the lists of all values for all parameters again from the device. Usually, after installing new firmware, the editor's effect definitions need to be refreshed. If you already have the latest firmware installed but want to re-install it for any reason, hold the Command key (Mac) or Ctrl key (Windows), while selecting the device in Fractal-Bot. Factory presets need only to be updated when the release notes say so. ![]() Updating firmware does NOT erase the factory or user presets. "Major revisions occur when there's a substantive change to the modeling algorithms." Updating firmwareįirmware must be installed using Fractal-Bot, Fractal Audio's updating utility, over an USB connection.įractal-Bot will indicate when an official firmware update has been made available. The Editors show the version in the top left corner. On the processor, go to the Utilities menu to see the installed firmware version. The current official version can be downloaded from Fractal Audio's support pages. The FC controllers also rely on firmware for basic functionality. There are a bunch of intrinsics that we use that are essentially assembly instructions but you can call them from C/C++." It's a VLIW processor so it's best to use the optimizing compiler and let it do the work. The DSP used in the Axe-Fx III is very difficult to write assembly for. The Axe-Fx I and II had a lot of hand-coded assembly as do the FM3/9. "Not much on the Axe-Fx III compared to the other products. (Is it true that you hand-code the firmware in assembly? You're not going to find a library that implements a Tube Screamer or even something more granular like a diode clipping circuit. I should add that these libraries are low-level functions like FFT() and such. The results are measurable and audible especially when dealing with the special requirements of amp modeling. 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. However every library I've seen makes the same mistakes in several important and oft-used functions. "Most DSP compilers include library functions for common signal processing functions. ![]() Mac computers do not require a driver (class compliant).įirmware is coded in C / C++ and assembly. The current official driver for the processor and operating system can be downloaded from Fractal Audio's support pages. Windows computers require installing a software driver for USB Audio and MIDI-over-USB with the Axe-Fx III and FM9. The current official version for the processor can be can be downloaded from Fractal Audio's support pages. The Axe-Fx III and FM9 rely on separate firmware for USB communications. The current official version for the processor can be downloaded from Fractal Audio's support pages.įirmware that supports DynaCabs cab models consists of two files: the firmware data and the DynaCab data. Fractal Audio releases updates frequently, adding new features and bug fixes. 8.4 Will repeating the installation of firmware fix issues?įirmware is the internal operating system for the processor.8.2 Editor is not in sync with the hardware.5 Audition presets after updating the firmware.
