Yet another expression pedals not working question



Bought a secondhand 1010 and I just can't get the expression pedals to do anything. I'm using a UM-ONE MK2 interface and the firmware is v2.4. I cannot see any MIDI in indication when trying the pedals.
I'II admit I am a bit of a MIDI newbie, but it appears (if everything is set upcorrectly) the pedals are 'off' by default ?

Any suggestions / advice appreciated !
