USB Firmware V 1.14 Release

Hi All,

A new version of the USB Firmware, v 1.14 , is available for the AXE FX III!

This release addresses several issues regarding latency stability and the actual latency of the unit itself. Here is a brief summary of improvements/fixes:
  • Importing a preset no longer changes the latency
  • Latency no longer drifts when an audio stream is active in certain cases
  • (macOS only) Latency no longer changes after a period of time after powering on the unit
  • Overall latency of the unit itself has been reduced
IMPORTANT NOTE ON USB BUFFER SIZE
This version of firmware uses a fixed internal USB buffer size compared to previous releases which used a configurable USB buffer. DSP firmware v 20.02 removes the USB Buffer Size option from the front panel when this (or later) versions of USB firmware is used. A future update to AXE Edit will remove the USB Buffer Size setting. This is not the same as the buffer size you set in ASIO/macOS. Those are still configurable.

Use the link below to download and follow update instructions below as well.

Legend!
The link in step 1 still points to the beta release.
Also I used FractalBot within Axe-Edit III (I haven't used the standalone FractalBot in a while).

There are two links. The top one is correct, the one under step 1 of the instructions is the old one (beta).

Is this USB update recommend for everyone? I've never had any issues with USB.
If so, should I update the USB before or after updating to firmware 20.02?
If you use the AXE FX III as an audio interface with your computer, then yes. Which firmware you update first does not matter.
