Hi Don , I ordered the unit at the end of January 2006 it arrived about a week ago .
They say the delay was because I ordered it with a 40gig hard drive as per the artical in the keyboard player magazine , this was in fact an error in printing as the Italian factory seem to know nothing about a extra large hard drive & left my order on the back burner so to speak.
In the end They sent it over on special delivery to the Uk .
In answer to your question I ordered the XP with the 6pedal foot switch .
It works fine .
The part number code :- 970.464
I have to say that the Expander and the 6 pedal foot switch are very well made and appear very robust , something that is essential when taking them out on gigs .

it comes with a very good quality canvas padded carrying case .

I've always been a "Technics boy " so I have to get used to a different operating system .
The good thing is that there is a lot of expertise with Dave and members of the Gem group .
It will be a learning curve and I expect I'll ask a lot of pretty dumb questions until I'm up to speed .
