Using the MC6 PRO to output expression pedal data over an omniport

I recently purchased the MC6 PRO and was trying to get it to do something with my El Cap v1. The El Cap can take an expression pedal and use it to adjust multiple parameters. How do I get the MC6 PRO omniport to mimic an expression pedal? I want to make a preset that sets the expression to 90 and one that sets it to 0, but I haven’t had any luck. Any help would be great!

You need something like an OBNE MTET.

The Omniports are expression in only, if you connect to an expression input of a pedal it might cause damage to your MC due to the control voltage. Check this
