Tuner in the Axe-Fx III

The Tuner in the Axe-Fx III has a new interface and better pitch detection. The eight-ball has been replaced by a spinning strobe wheel.

Mini-tuners appear on various places on the hardware GUI.

Source input for tuner

Ace-Fx III: lets you select which input should be used.

Axe-Fx II: detects signals at the front input of the Axe-Fx II, at Input 1 at the rear and in the S/PDIF signal. This cannot be changed. If Input 1 Mode is set to Left Only, the Tuner picks up the source signal at the rear left input only. If it is set to Sum L+R, the Tuner picks up the source signal at the left and right rear input.

AX8: detects signals at the front input.

FX8: detects signals at the PRE input. You can change the Global Detector to POST input, which you'll want to do when using the FX8 in a POST-only setup.

Muting the output

The sound can be muted when engaging the Tuner. You have the choice of muting at the Input or Output stage. Muting at the input stage allows delay and reverb trails to continue to sound when engaging the Tuner. The Mute parameter is in the Tuner menu.

Remote control

Footswitch

Scroll to the Tuner CC (I/O menu) and hit Enter. Click the switch on the footswitch that you want to assign the Tuner to.

Or configure it manually by assigning the Tuner MIDI CC to a switch on the floor controller.

MIDI CC

Default MIDI CC for the Tuner is 15 in the Axe-Fx II, AX8 and FX8. Keep this setting to avoid problems with MIDI controllers.

MFC-101

The MFC-101 has a dedicated Tuner command. This does not work with the Axe-Fx III.

You can also program the MFC-101 to turn on the Tuner by pressing a "preset" switch:

  1. In Edit > MIDI, set IntCC00 to CC15.
  2. In Edit > Preset, scroll to the designated preset and set IntCC01 to On.

3rd-party MIDI controllers

Certain MIDI foot controllers (i.e. Gordius, RJM, Liquid-Foot) can show a graphical tuner display when used with the Axe-Fx II:

  1. Enable real-time MIDI SysEx communication on the Axe-Fx II (I/O > MIDI) by setting it to “Tuner” or "All".
  2. Use a suitable cable connection which allows full bi-directional MIDI communication.

This does not work with the Axe-Fx III tuner because the Axe-Fx III has a proprietary communications protocol. MIDI controllers need to act as a client to the Axe-Fx III to be able to communicate, by implementing Fractal Audio's protocol.

Sweetened tunings

Use the offsets below in the Tuner for Peterson GTR Sweetened tuning. source

E1 = -2.3 cent
B2 = 0
G3 = 0
D4 = -0.4 Cent
A5 = -2.1 Cent
E6 = -2.3 Cent

To apply: press the Tuner button, move to page 2 CONFIG, set USE OFFSETS to "ON", move to page 3 OFFSETS, adjust each string to the above offsets.

Troubleshooting

"Waiting for tuner..." message on MFC-101

If this message appears on the MFC-101 after pressing the Tuner switch on your foot controller, check these Axe-Fx II settings:

  • I/O > MIDI: Send Realtime Sysex must be enabled.
  • Tuner menu: must be set to display the first tab page.
  • Tuner MIDI CC: must be set to default.

Flickering Axe-Fx II display

"Display flickering on the tuner is normal. Some do it more than other. It's just the nature of the display. The display uses a ping-pong buffer. One page is updated while the other is displayed. Then the pages are switched. Some flickering can occur during the page switch. The reason it is noticeable more on the tuner is that the display is updated more frequently." source

Wrong tuner value when not using 48kHz sampling rate

If the Axe-Fx is connected to a DAW which is not set to 48kHz, the tuner settings may be off.
