Just a quick update ,
Had a private e mail from Dave McM with assistance (dispite his raging tooth ache )
Now that deserves a dedicated manager of the month award !!! in my book !!

Auto reload did not work .
So loaded from supplied cd all styles and had to go thro the load sequence for all the user 2 styles 1 to 8 . ie pop thro to world .

everything is back to normal (what ever that is !!) midi settings were uneffected !!so at least it did not involve a call out from the music shop engineer to reset everything for my midi accordion .

I've learn't a number of things :-
If it ain't broke don't try to fix it !!

seriously do not load a complete style folder as it will completely over write everything .
Load on a single style basis only !!
if this had happened on a gig it would have been terrible !!!

I'm still not sure how to load styles from a floppy disk so if anyone wants to tell me I would be pleased to have the information .
