If the looper is loaded into Slot A, press the A LED button to cycle through the options. Only 1 option may be selected. You can use the dedicated looper page to access more than 1 option.

To map the parameters to MIDI controllers or aux switched:

Press and hold any of the LED buttons (P/A/B) and this will open the Performance Parameter Mapping menu.

Use Quick Knob 1 to select a parameter (example: Record) and use Quick Knob 2 to select a control source (example: CC1)

Now, CC1 will toggle the record function.
