Using an Expression Pedal on an MFC-101
16.12.2
The process for using an expression pedal connected to a Fractal Audio Systems MFC-101 MIDI Foot controller is
almost the same as that required for the onboard PEDAL jack.
1.
Connect the pedal to the MFC-101
PEDAL 2
jack. (Pedal 1 is pre-programmed for VOLUME control.)
2.
Calibrate the pedal.
3.
With default settings on both MFC-101 and Axe-Fx II, no custom I/O parameters are required.
4.
Assign the External Controller to the Wah parameter
.
Here are the steps in greater detail:
Please note that this section assumes your MFC-101 has factory default settings. To return an MFC-101
to factory default settings, press the #11 footswitch and reboot the unit by disconnecting it from and
reconnecting it to power.
WARNING! THIS WILL ERASE ALL USER SETTINGS ON THE MFC-101!
1)
Connect an expression pedal to the #2 onboard pedal jack of the MFC-101. (Pedal Jack #1 is pre-
configured at the factory to control OUT1 VOLUME on the Axe-Fx II.)
2)
Calibrate the pedal according to the instructions in Section 7.1 of the MFC-101 Owner’s Manual.
Be sure
to change to “XP2” at Step 5!
3)
Since Expression Pedal #2 on the MFC-101 is pre-configured to send MIDI CC# 16, and MIDI CC#16 is pre-
configured to control EXTERNAL 1 on the Axe-Fx II, no special settings are required in the I/O menu for
this tutorial.
If you were using a different MIDI controller, or if you had XP2 assigned to a different CC#, you would use
the CTRL page of the I/O menu to set the desired EXTERNAL CONTROLLER to the desired MIDI CC number.
4)
Assign
External 1
to control the Wah:
a.
Press
to view the grid.
b.
Select or insert a WAH block.
c.
Press
to open its edit menu.
d.
Find and select the
CONTROL
parameter.
e.
Press
to view the MODIFIER screen.
f.
Change the
SOURCE
to EXT 1. Test the pedal to see the dot on the screen moves. If it doesn’t
move, check the above steps again, starting from #1, or try a different pedal/cable.
i.
OPTIONAL: to change the FEEL of the Wah, try adjusting the value of
MID
.
ii.
OPTIONAL: to make the Wah “smoother,” adjust
DAMPING
to a value from 1–20 ms.
iii.
OPTIONAL: to set the Wah so it turns on and off automatically when you move the
pedal, scroll down on the MODIFIER SCREEN and change the value for AUTO ENG to
anything but “OFF.” (See p.
g.
Press
to return to the WAH edit menu. Make other adjustments as desired, such as setting
the range using the
MIN
/
MAX FREQUENCY
, or adjusting the
RESONANCE
and
TRACKING
.
h.
STORE the preset to save the new wah and modifier settings.
Again, please recognize that MODIFIER assignments are not global. You must repeat Step 4 for every preset where
you want the pedal to control the Wah. The advantage of this, however, is that in another preset you will be able
to use the same pedal to control a Whammy, or the feedback of a delay, or any other parameter that allows the
use of a Modifier. See Modifiers & Controllers on p.
