Hi!
GlennT,
First you have to register (you can go to groups.yahoo.com)
The best tip is, after registering, just join any group in english, so you can understand how to do it.
Then just follow this link
http://fr.groups.yahoo.com/group/KetronSoltonworld/ and the do exactly the same thing because all the buttons are at the same place! The most important thing is the "Fichiers" (= Files) section where you can find a lot of styles for the SD1!
Any questions, just post them!
