I'm confused. Do I need a MIDI foot switch to trigger record externally?
The OP seems to be using a momentary switch.
I've got a momentary switch plugged into pedal 4 set up as a momentary switch in the pedal menu and can assign looper record to trigger from pedal 4 but nothing happens.

You can assign anything under SETUP->IO->CTRL to Pedal 4, but only the first assignment in the list will work.
By default EXT CTRL 4 is set to PEDAL 4. Set it to NONE. Assuming you don't have anything else also assigned to Pedal 4, it should then work for LOOPER REC.
