How to activate "Midi Out" for Scarlett 18i20 ???

I would like to connect Cubase LE with my Roland RD2000 via my Scarlett 18i20.

Midi In works fine.

However, Midi out seems to be deactivated:


How can I switch the Midi out “on”? Clicking on it does not help nor does the Ficusrite software offer any Midi activation.

Thanks for your kind support!

connect it on a track in cubase.
