External Foot Controllers
Eleven Rack has a 1/4” TRS input that can accept
input from an expression pedal or a single or
dual momentary footswitch.
Expression Pedal
An expression pedal can be used to control con-
tinuously variable parameters within Eleven
Rack, such as volume or wah position.
In addition to commonly-used expression ped-
als, a standard volume pedal with a “Y” adapter
cable (two 1/4-inch TS plugs to one 1/4-inch TRS
plug) can be used, though keep in mind that the
taper of the potentiometer in a volume pedal is
exponential, rather than linear as in an expres-
sion pedal.
Expression Pedal Calibration
The response of expression pedals vary slightly
from model to model, and even unit to unit, so
it is important to calibrate Eleven Rack to follow
your pedal’s sweep correctly.
To calibrate Eleven Rack to your expression pedal:
1 Hold the Edit/Back button to enter User Op-
tions mode.
2 Use the Scroll wheel to navigate to External
Pedals.
3 Press Select to access the External Pedals set-
tings page.
4 Press Calib to enter calibration mode.
5 Move the expression pedal to its heel position,
and press Next.
6 Move the expression pedal to its toe position,
and press Next.
7 Sweep the pedal to test its functionality. If the
pedal is working correctly, the Active indicator
on the display will light up.
8 Press Done to exit calibration mode.
9 Press Edit/Back twice to return to the previ-
ously chosen screen.
Momentary Footswitch
(Single or Dual)
Most single or dual momentary footswitches
can be used to toggle various switched functions
within Eleven Rack, such as effects on/off and
cycling through rigs.
Choose a momentary footswitch with a
1/4-inch TS (single switch) or 1/4-inch TRS (dual
switch) connection.

and footswitches with Eleven Rack, “Exter-
nal Pedals” on page 95.
