Fractal Audio Systems MFC-101 Manual
To set global Expression Pedal functions, use the following process:
1. Press the EDIT footswitch to enter EDIT MODE.
2. Press MIDI footswitch to select the MIDI menu.
3. Press PAGE footswitch 15x to get to the Global Expression Pedal Setup screen:
XP1 #011 Ch01 BegOFF
4. Press INCR or DECR to select an expression pedal to edit: XP1, XP2, XP3 or XP4.
5. Press PARAMETER footswitch to select the CC# field.
6. Tap and/or hold the INCR or DECR footswitches to assign a MIDI CC# from 0-127 or OFF to
disable the pedal completely.
7. Press PARAMETER footswitch to select the MIDI Channel field.
8. Tap and/or hold the INCR or DECR footswitches to assign a MIDI channel.
9. OPTIONAL: Press PARAMETER footswitch to select a Beginning Value for the selected pedal.
This value will be sent when any new preset is loaded as follows:
PDL
OFF
000-127
10. Press PARAMETER to return to the first cursor position and repeat this process to assign
functions to additional pedals, or press EXIT to return to PERFORMANCE MODE.
NOTE: Pedal #1 is mapped by default to MIDI CC#11 (default for "Output 1 Volume" in the Axe-Fx), and Pedal #2 is
assigned to MIDI CC#16 ("External 1" in the Axe-Fx, which often controls Wah or Whammy).
7.3 Expression Pedal Range
The range of an expression pedal—the minimum and maximum data values sent for the heel and toe positions—
may be modified both globally (12.4.17) or within an individual preset (12.1.10).
For maximum flexibility, Axe-Fx users will likely want to leave expression pedal range settings at full (0–127) and
instead map control relationships using the MODIFIER settings: START, MID, and END points, SLOPE, SCALE and
OFFSET. See the Axe-Fx manual for more information on Modifiers.
Doc v2.15
(Default) The pedal will be polled and a corresponding MIDI value sent whenever a new
preset is loaded.
The Beginning Value function is switched off. No data is sent until the pedal is moved.
The selected value will be sent whenever a new preset is loaded.
To prevent abrupt sound changes, a pedal with a numeric Beginning Value will send
updates only after its physical position crosses the threshold of the beginning value. For
example, if the initial value is "0", you will need to move the pedal to "0" (heel position)
before the pedal sends any MIDI data.
The "Beginning Value" should never be set outside the MIN/MAX range of the pedal,
whether global (12.4.17) or set for the Preset (12.1.10).
