MIDI Introduction

MIDI (Musical Instrument Digital Interface) is a very powerful protocol that allows musical instruments as well as computers to communicate with each other.
This MIDI section of Axe-FX Wiki is intended to cover those features and uses as they apply to the Axe-FX Standard and Ultra by Fractal Audio.



MIDI would be primarily used for 6 purposes regarding the Axe-FX.

  1. To upgrade firmware (operating system).
  2. To have ability to backup and restore Axe-FX presets.
  3. To edit Axe-FX presets via computer software editor.
  4. To select presets via MIDI footswitch.
  5. To control various individual functions via a MIDI controller.
  6. To transfer settings and presets from one Axe to another.

Basic Principles: MIDI is laid out in banks. A bank is 128 presets (or patches) which would be numbered either 0 to 127 or 1 to 128.

The Axe-FX utilizes 3 Banks (labeled A/B/C) of 128 preset slots each for a total of 384 configured as follows (non-offset mode):

  • Bank A ~ 000 to 127
  • Bank B ~ 128 to 255
  • Bank C ~ 256 to 383

Pre v5.00 Firmware ~ Banks A/B were supplied with duplicate, editable factory presets.
Post v5.00 Firmware ~ Banks A/B were unique presets for a total of 256 editable factory presets while Bank C had 128 empty preset slots for custom user creations.
Post v5.22 Firmware ~ 128 New Bank C presets introduced for a total of 384 Factory Supplied Presets. These reflect Ultra configurations with Standards most often quickly following suit.

Getting Started

MIDI In/Out/Thru

Getting Started: The Axe-FX has 3 MIDI connections. In/Out/Thru. In/Out of the device are obvious. The Thru is a duplicate of the In signal allowing a 'daisy chain' of devices to be formed. MIDI cables are also necessary to get started with any MIDI purpose. Standard MIDI cables are 5-Pin DIN as shown above as the Out and Thru sockets. Notice the In socket is a 7-Pin DIN. It will accept either a 5 or 7 Pin Cable. Above the MIDI sockets on the Axe is a connector called Phantom Power In. You can plug your MIDI device power adapter into this plug and utilize Pins 6/7 of your MIDI cable to power your MIDI device. That way you have one clean cable run for both power and MIDI to your footswitch (for example).

TipTip - Since you will be going from the Out of one device to the In of the other and the In of that device to the Out of the other it is easy to get lost in your connections. Try using 2 colors of MIDI cables (ex: red and black) and designate a 'go-to' device and a 'go-to' cable. Now by using 'Blackout' as a key word and the Axe as the key device the reference is black cable to Axe MIDI out.

2 colors and a keyword easily keep 4 connections straight.

MIDI Hardware

MidiSport 2x2 MIDI Interface

MIDI Interface - We need a MIDI interface to allow us to communicate with our computer and software.

Rolls MX128 Midi Buddy Footswitch

MIDI Footswitch - This will usually be a 12 button footswitch. It will have 10 presets, a Bank Up and a Bank Down button. Primary purpose is for preset selection.

Axess FX1 MIDI Foot Controller

MIDI Controller - This is a powerful variable controller which uses Continuous Controller messages. Many times this type of device will have a volume or wah pedal (or both). It will also have various switch buttons which can be used as the MIDI footswitch above or to turn off/on individual effects such as chorus, reverb, flange, echo, etc. It is by far the more complex of the setups.
