USB drivers

  • Drivers for Mac and PC which add USB connectivity are available for download here.
  • The USB driver's control panel should not be used for configuration. Ignore error messages when clicking on the controls. Source1 Source2 Source3
  • The names on the computer of the Axe-Fx channels are assigned by the computer, not by the Axe-Fx. Source

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. 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. Source

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

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 a ground loop. Make sure everything is plugged into the same outlet strip." Source

Dry tracks

If you're recording with the use of an application which uses the system selected input (all 4 channels), you will end up with a recording that also contains the dry tracks. The Axe-Fx II currently doesn't let you mute the dry tracks. Source

USB storage media

The Axe-Fx II cannot connect to a USB stick. Source
