Thanks for your reply. I know what I did wrong. I was not in single sound mode.
About your question.
The XP came in a suitcase. To me it seems that the XP is very solid. The wheel however needs additional protection when you take for a gig. Since I don't do any gigs this is not a great issue for me.

The reason I asked about voice changing is this: the XP comes not with real sounds. They are on the disk but not preinstalled. So now they are user sounds. Now I can try to put these real sounds in the styles.

Greetings Johan
