key switch import

I’m using cubase 7.5 and am trialling the Halion symphony instrument and I don’t get an “import key switch” option in my pop-up tab for the expression map. Don’t want to spent $100 if I can’t make use of that function, has anyone encountered this?

Quick check - when viewing the loaded sample patch in HS or HSse - are the various expressions on?
Check the EDIT window.
