Controller Assignments
The Controller Assignment function allows for specific Xpression
™
adjustable parameters to be
mapped (or assigned)* to a MIDI controller for real-time control by an expression pedal.
The Controller Assignment option also lets you store an upper and lower parameter value limit
which the controller cannot exceed. For example, when using an expression pedal with a Rocktron All
Access
™
,MIDI Mate
™
, MIDI XChange
™
footcontroller to send continuous control changes to control
the "PITCH" parameter, an upper limit of +300 can be set and a lower limit of -200 can be set - even
though the actual parameter range is from +1200 to -2400. When the expression pedal is at its heel
position in this example, the "PITCH" parameter will be at -200, while at its toe position it will be at
+300. Up to ten controllers can be assigned for each individual preset.

Step 2
To access the Controller Assign function, turn the FUNCTION SELECT control clockwise to
"CONTROLLER ASSIG".
This parameter (CTR A only) also gives you the option of selecting "ADJ". When "ADJ" is
selected, the parameter assigned to the first controller (PA-A) can be instantly accessed by
turning the PARAMETER ADJUST control when the preset title is displayed. This allows you
to access a parameter that you adjust frequently without paging through function headings
and parameters.
Turn the PARAMETER SELECT control for the first parameter of the Controller Assign
function. This parameter allows you to select a controller number for the "CTR A" (Controller
A) parameter to respond to.
