Hi

Get the expansion packs from http://services.music.yamaha.com/vse
Unzip the packs. There is a ".yep" file and some other files in the archives.

Get my "Style in YEP Files" software program from http://www.jososoft.dk/yamaha/software/yep/index.htm

In this program open the ".yep" file...
Styles will be extracted automatically... and saved in a sub folder to the ".yep" file folder...

Tweak styles to your keyboard...

Enjoy
Jørgen
