Controlling Timeline Looper Level via Exp Pedal

Hi There,

Trying to control my timeline looper level via expression pedal. I know the expression pedal should send a CC# on 98 to the Timeline but nothing is happening to a loop when doing that.

Just figured out the EXP1, EXP2.. relate to the Omniports. My exp was set to Omniport 2 so I should set the CC message up on EXP2. Face palm but also I dont think that is very clear tbh
