Omnisphere - Last touched parameter greyed out?

[Mavoz]

Hi,
I'm trying to train the cutoff dial in Omnisphere via the Parameter menu...Learn..
But when I press the dial on the cut off...and go to parameter menu..it is totally greyed out and says:

"No recently touched parameter"

Is Omnisphere not capable of this?

If I go to Alicia Keys for example..it works fine..

I've seen other videos where people are able to train the Omnisphere controllers with a Midi controller....there must be some way?

Thanks for any clues!
