Tuner: supported by which Fractal Audio devices?

Tuner MIDI CC

MIDI CC for the Tuner: 15.

Remote Tuner control

Switch

Scroll to the Tuner CC (I/O > Control) and hit Enter. Click the switch on the MIDI foot controller 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.

MFC-101

The MFC-101 has a dedicated Tuner command.

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.

Source for Tuner signal

The Axe-Fx II's Tuner 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.

FX8: at default settings, the Tuner 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.

AX8: the Tuner detects signals at the front input.

Tuner mute

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.

Tuner display on floor controller

Fractal's MFC-101 and certain controllers (i.e. Gordius, Liquid-Foot, RJM) can show a graphical tuner display:

  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.

Tuner issues

"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:

Flickering Axe-Fx II display

Fractal Audio:
"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 II is connected to a DAW which is not set to 48kHz, the tuner settings may be off.

Use 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.
