Hi Impuls

None of those options relate to the Wing, they are for OAS 7 instruments and have been added over time to allow users of earlier instruments to upgrade to the latest features. (All manufactures do the same, however unlike the Wersi OAS instruments you have to buy a brand new keyboard to get them)

BTW Most of the options are standard on New OAS 7 instruments. (Excluding sound packs of course)

Hope this clears up the misunderstanding.
