How to upload cabinets

With version 4.0 of the firmware, the Axe-Fx is able to use up to ten user cabinets. This process involves creating or obtaining an impulse response of an existing cabinet, converting it for use with the Axe-Fx and uploading it.

Obtaining an impulse response

You can record your own impulse response by sending a short burst of noise or a sine sweep to your cabinet and recording the result. The resulting signal is the impulse response of the cabinet and the microphone combined. Please see the main article on impulse responses for more information.

Converting an impulse response

Follow these steps, skipping any that don't apply. If you aren't comfortable with any of these steps, wait until the conversion utility is updated with more features.:

• Convert the file to a mono .wav.
• Zero pad the .wav to 4k (4096) samples or more. (Value for 48kHz. Scale accordingly for other sample rates.)
• Use the FAS conversion utility to convert the .wav into a SYSEX (.syx) file.
  • Place the wave file(s) you want to convert in the bin/win32 folder.
  • Launch the utility and follow the prompts.
  • The resulting sysex will now be all ready to load into the Axe-Fx in the location you specified.

Uploading the impulse response

Simply transfer the SYSEX file to the Axe-Fx using whatever software you use to transfer patches.

The Axe-fx Editor will load cabs automatically. Just go to File-Upload User Cabinet to Axe-fx and choose location.

AlbertA's Axe-fX IR converter Utility will also load User cabs. Just open the .syx file, choose a location, and send to axe-fx.
