Yesterday I finally got the XP.
To connect it to the Tyros was very easy.
But then it went wrong. I couldn't load styles, so I reinstalled the software. Still I got problems so at 2 at night I put it off. Today I went to the shop and it seemed that I received the wrong OS. They completely replaced the XP, I got a new one.
Compliments to Ernst from general music Benelux. As a coincedence they were demonstrating the XP. To make a long story short, I went home and started playing.
My first impression, what a sound! In the coming days I will post more findings. Greetings.
