Controller Assign
Helix provides a wide variety of tools for controlling your tone during a performance.
The most obvious one is the built-in expression pedal (often assigned to wah or
volume), but you may also assign footswitches to toggle between two values of a
given parameter or parameters, control a parameter from an external MIDI device,
or even from the volume and tone knobs on a James Tyler Variax or Variax Standard
guitar.
If a controller has been assigned to a parameter, the value appears white and in brack-
ets:

[37%]
NOTE: Adding a Wah or Pitch Wham block automatically assigns it to be con-
trolled by EXP 1. Adding a Volume Pedal or Pan block automatically assigns it to
be controlled by EXP 2.
NOTE: Each preset can have up to 64 controller assignments. If you attempt to
add a 65th, "Too many controller assignments!" appears in the header:
