Use as MIDI Clock source

• The Axe-Fx II cannot be used as a source for MIDI Clock to other devices. Source

Send Realtime SysEx

• The Axe-Fx II can send MIDI data continuously to a MIDI floor controller. This allows the controller to display tuner data on the floor controller's display and make a tempo LED on the floor controller blink in time with the Axe-Fx II tempo. Transferring this data requires a 5-pin MIDI cable between the Axe-Fx II and the floor controller, or the CAT5 or Ethercon cable to the MFC-101.
• Realtime sysex is disabled when entering the Utility menu. This is useful when using the Dump commands.

Display Offset

• The Axe-Fx II starts numbering presets at 0. This parameter lets you change the displayed number. This is particularly useful to improve compatibility with MIDI devices that start numbering at 1 or when configuring a floor controller such as the MFC-101.
• Note: when adjusting this parameter, don't forget to configure the MFC-101 accordingly.

Ignore Redundant PCs / Resetting the preset

• If set to Yes, this parameter tells the Axe-Fx II to ignore an incoming PC (MIDI Program Change mesage) if the corresponding preset is already active. This prevents unnecessary reloading of the preset and the short gap in the audio signal that comes with that.
• In some cases you may want to set this parameter to No. The Axe-Fx II will then reload the current preset again. This means that the effects in the preset will be reset to to their saved states. This is an easy way to "reset" a preset by pressing its switch on the floor controller a second time.

Connecting a keyboard to the MIDI ports

• Firmware 4.00 introduced MIDI support for connecting a keyboard and other devices than floor controllers to the MIDI ports.

MIDI Thru limitations

• Cliff: "The Axe-Fx II is not designed to be a general-purpose MIDI I/O. It can handle most things but not large sysex dumps." Source
• Cliff: "The Axe-Fx simply passes the data. It doesn't parse messages. If a message is arriving altered then the fault is in the monitoring software or the OS." Source
• Cliff: "MIDI Thru is a "soft" thru. It the delay is problematic for you then you need to change the order of things or use a MIDI splitter." Source

MIDI phantom power

• The Axe-Fx II can provide power to a floor controller via a MIDI cable, also known as "MIDI phantom power". This requires:

1. 7-pin MIDI cable (pin definitions) and
2. the power supply for the floor controller to be plugged in at the rear of the Axe-Fx II.

• Looking for the right cable? Read this: Cables for Fractal Audio products (Best-Tronics).
• If you have a MFC-101, it's easier to use a CAT5 or Ethercon cable instead of MIDI.
• Warning: do not connect a power supply to the phantom power input on the Axe-Fx II that has a load of more than 1A! E.g. the power supply that comes with a Liquid-Foot 12+. More information
