Parameter Column
e Parameter column shows all Program and FX parameters for the current program. 
Eect Chain parameters are named with prexes based on their eect type: “INS” for 
parameters from Insert eects, “LFX” for parameters from layer eects, and “AUX1” or 
“AUX2” for parameters from Aux eects.
To quickly nd a parameter that is already assigned to a controller, select the parameter 
column, hold the ENTER button and move a controller to select the assigned parameter. 
Control Column
e Control column determines which physical controller (or external MIDI CC number) 
will control the parameter in the selected row. To quickly assign one of the PC4 SE’s physical 
controllers to a parameter, select the control column in the row of the desired parameter, 
hold the ENTER button and move the desired controller. Alternatively, you can use the 
ALPHA WHEEL to select a controller from the list, or type in the controller’s MIDI number 
followed by the ENTER button. See below for a list of PC4 SE physical controllers and their 
associated MIDI numbers.
If you want to disable the controller for a parameter, you can select a value of None by 
scrolling to the bottom of the controller list.
To choose an external MIDI CC number as a control source, you can enter the number of 
the controller followed by the ENTER button, or use the ALPHA WHEEL. e PC4 SE’s 
physical controllers each use one of the available MIDI CC numbers, so you must choose 
one of the other available CC numbers when using an external MIDI control source or else 
the parameter will also be controlled by a PC4 SE physical controller. MIDI CC numbers 
associated with the PC4 SE’s physical controllers are shown in the list below.
