HSO on Halion SE


I am a proud owner of Cubase 6 now and I upgraded from cubase 5.
There I had a licence fo HSO.
So I can use the new version of HSO in Halion SE.
Only I noticed that the sounds of HSO sound much less loud than the other sounds in Halion SE.
How to solve this problem?
Where can I find the expression maps for HSO and Halion SE?

Thank you for you reply
