Driver for USB connectivity
- Drivers for Mac and PC which add USB connectivity are available for download here.
- It's not an driver in the conventional sense. It's a daemon that waits for the Axe-Fx USB port to appear and then downloads software to the port to make it USB class-compliant. The plist file is located here: /Library/LaunchDaemons/com.fractalaudio.axefx2load.plist.
- The USB driver's control panel should not be used for configuration. Ignore error messages when clicking on the controls. Source1 Source3
- The names of the Axe-Fx channels on the computer are assigned by the computer, not by the Axe-Fx. Source
- If using AxeEdit, you will still need to go to Settings > MIDI Settings and select the Midi In and Out ports for it to use. They should be named something like "AXE-FX II MIDI In" and "AXE-FX II MIDI Out".
No MIDI interface or audio interface required
- When using the USB interface, there's no need for an additional audio interface. An audio interface is still required when connecting the analog Axe-Fx II outputs to a computer instead of using USB.
- A MIDI interface is also not required to connect the Axe-Fx II to a computer. USB suffices (MIDI-over-USB). The Axe-Fx II itself is an USB-to-MIDI adapter. MIDI interfaces can still be used though, and editing with the help of a MIDI interface is also still possible.
Using the Axe-Fx II to update the MFC-101 firmware
The Axe-Fx II can be used as a USB-to-MIDI interface to update the firmware on the MFC-101. Read this
USB connection increases CPU utilization
Creating an USB connection increases CPU utilization (by design). If a preset uses much CPU cycles, you may run into CPU overload problems when connecting the Axe-Fx II to a computer through USB. Source1 Source2
Latency
When monitoring audio via the Axe-Fx II, latency is none. When monitoring the audio signal via the computer's output, latency depends on computer. Source
Solving USB noise
High-pitched noise may be caused by a ground loop.
Cliff: "The USB spec calls for grounding the cable at both ends (mistake). This can create an USB ground loop. Make sure everything is plugged into the same outlet strip." Source
USB storage media
The Axe-Fx II cannot connect to an USB stick. Source
