Mark I, Mark II and Mark III models

• Changes in Mark II:
  • Cliff: "The only change is the CAT-5 connector is now an Ethercon jack. An Ethercon jack will work with either a CAT-5 cable or an Ethercon cable." Source
• Changes in Mark III:
  • Solid-State switch technology. No moving parts except a spring "actuator". Switching is fully electronic and silent with no switches to wear out. Mechanical lifespan 1 million actuations.
  • "FASLINK" jack: a new, proprietary communications link that features bi-directional MIDI and power over a standard XLR microphone cable. Cable runs of hundreds of feet are possible. You need a FASLINK adapter (XA-1) to convert XLR to Ethernet/Ethercon on the Axe-Fx side, or use the Axe-Fx II XL with built-in FASLINK connection. If you want to use a XLR cable with MFC-101 Mark I/II models, you also need a FASLINK adapter (XA-2) at the MFC side.
  • Requires separate firmware.

Connection and power

• Ways to connect and power the MFC-101:

1. You can use the supplied 9VAC adapter to power the MFC. This is also the recommended power method when upgrading the firmware. Do NOT connect the adapter to the MFC simultaneously with the use of an Ethernet, Ethercon or XLR cable, or when using MIDI phantom power, or damage can occur!
2. MIDI can be used for just communications or for communications and power (phantom power). A good MIDI cable is required! To receive tuner and tempo data all pins of a 5-pin MIDI cable must be connected. Many low-cost MIDI cables just have 3 pins connected and are not properly shielded, resulting in audible data transfers. To use phantom power via MIDI a 7-pin MIDI cable is required and all pins must be wired (pins 6 and 7 carry power), and connect the 9VAC adapter to the phantom power input at the rear of the Axe-Fx. The Axe-Fx doesn't provide power itself, it needs the power supply.
3. You can use a CAT5 Ethernet cable for communications and power. It provides power to the MFC-101 without the need to connect the adapter to the Axe-Fx II, transmits MIDI data and tuner and tempo information, and switches off the MFC-101 when the Axe-Fx II is switched off. The MFC-101 Mark II and III models also support Ethercon connections (sturdier than Ethernet). When using Ethernet/Ethercon, the MFC's MIDI OUT port won't pass data anymore, you can't use both ports simultaneously. Source
4. On the Mark III model you can also a XLR cable to power the MFC and transfer data. You need a FASlink adapter (XA-1) to convert XLR to Ethernet/Ethercon at the Axe-Fx side, or use the Axe-Fx II XL with integrated FASLINK. If you want to use a XLR cable with Mark I/II models, a FASlink adapter (XA-2) is required at the MFC side.

• Use Edit > MIDI to set the MFC-101 to the correct cable connection.
• A propietary communication protocol is used for bidirectional communication and phantom power. The internal PSU for the MFC-101 will also support an expansion module for the MFC-101. Source1 Source2 Source3
• More information about connecting and powering the MFC-101 in the Owner's Manual.
• Do not power up the Axe-Fx after the MFC. Otherwise none of the switches will work (until a preset is switched). Cliff: "This happens when the Axe-Fx II is not powered on first. Selecting any preset on the MFC will reset the state machine." Source
• Cliff: "Do NOT attempt to extract power from the MFC connector. It is only rated for 1A and if you burn out the port we won't cover that under warranty." Source
• Forum member Chrisallen8888 made videos explaining how to set up the Axe-Fx II and the MFC-101 for basic use as well as how to configure expression pedals:

Essential configuration

• Quick Start guide
• Make sure you select the correct Axe-Fx II model and type of connection.

Firmware updates

• Go to Edit > Setup to see the currently loaded firmware version.
• Fractal Audio Support Download the latest firmware, launch Fractal-Bot and follow the instructions. Note that there are different firmware files for Mark I/II and Mark II units.
• The update process requires a MIDI interface (the Axe-Fx II can be used as such. Updating is not possible via Ethernet/Ethercon. And during the update process, the MFC-101 cannot be powered via MIDI phantom power. The firmware file includes a handy Read Me - Firmware Update Guide, explaining the process. It also explains how to use the Axe-Fx II as a MIDI interface, and how to power the MFC-101 via Ethernet/Ethercon during updating if you haven;t got the power supply.
• An upgrade may require you to reset the MFC-101 to its factory settings. If so, it will be stated in the release notes. To reset the MFC-101, power on while holding switch #11. Note: this erase all configured settings! You can save these on forehand and restore these afterwards.
• If you're experiencing problems, open the Utility > Preset page on the Axe-Fx II. This makes sure that the Axe-Fx II is not sending out stuff which could interfere with the update process.
• All firmware release notes can be found here: MFC-101 firmware release notes.
• Error messages during updating:
  • Error 14: rare problem that occurs after a failed firmware update. Once this occurs, you can start over to achieve success, but the MFC-101 will “time out” if the update is not completed quickly enough, causing the unit to display ERROR 14 again. Decrease the MIDI Buffer Delay setting in Fractal-Bot (In step 1 “READY”) to 90ms or lower to speed the firmware transmission process.
  • Error 16: usually indicates that the MFC saw “garbage” during a firmware update. This problem is often seen when using “inferior” MIDI Interfaces, but can also indicate computer problems, or even a bad MIDI cable. In rare cases, re-downloading the firmware update can also solve this problem.
  • Error 18: indicates that the MFC-101 has received some stray MIDI message while awaiting a firmware update. Please make sure no other MIDI applications are running on your computer, or, if using the Axe-Fx II as a MIDI Interface, ensure that I/O: MIDI: SEND REALTIME SYSEX is set to “NONE”.
  • The manual explains more error messages.

Backup and restore

• Use Edit > Setup > Sysex Data.

Resetting to factory defaults

• Power the MFC-101 while holding switch 11. The manual lists all factory default settings.

Brightness of LEDs

• Put small bits of painter's tape on top of them. Or use this smart and simple solution.

Programming

• Use the Edit menu. There's no software editor. You may have to press Edit for a couple of seconds (long press), depending on a configuration setting. This prevents accidental entering Edit mode during live use.

TotalSync

• When you switch presets on the front panel of the Axe-Fx II, the MFC-101 can switch along. It's called TotalSync. You switch this on/off in the MFC's MIDI menu.
• TotalSync doesn't work in Song and Set modes, and custom MFC-101 Tx Map and Axe-Fx II preset remapping (for example to support scenes) are not supported.

MFC-101 and Axe-Edit

• It's recommended to not use the MFC-101 while Axe-Edit is running. It's possible to do so, but using the MFC-101 can cause audio gaps, and fast switching can cause communications issues.
• Engaging and bypassing effects through the MFC-101 will not always update the block states in Axe-Edit. To make Axe-Edit recognise such changes, its polling mechanism must be engaged. This can be accomplished to attach the Bypass parameter of any block in the preset to a controller.

Tuner and Tempo

• To show the Tuner display and see the Tempo LED blink in the correct tempo, the MFC-101 must be in Axe-Fx Mode. Also, a connection type must be used which supports this: 5-pin MIDI, CAT5 (Ethernet/Ethercon) or XLR. On the Axe-Fx II (I/O > MIDI) Send Realtime Sysex must be set to to Tuner, Tempo, or All.
• The MFC won't display the Tuner when using an external switch to switch it on. It will be displayed on the Axe-Fx though.
• When the Tuner on the Axe-Fx is set to anything other than its first tab page, the message "Waiting for tuner" appears.
• When the tuner display is active, it's still possible to engage/bypass other effects, switch banks, presets and songs etc.
• You can combine Tap Tempo and Tuner functionality: hold Tap Tempo will enter the Tuner mode. Use Edit > Setup to set this up. This does not work with external switches.
• How to create a tuner "preset" instead of an IA switch.
