The USB software came in a CDROM with thousands of styles for your arranger. There was no instruction for the software but i guess you dont need any. These styles were devided by manufactures and models. Can download USB style list at their web site.
I had a little problem with all Yamaha styles. When it is loaded in my Solton the entire drum part were missing. I had e-mail the author and he said the new version (to be released in November) will correct all that. I hope that answer your question.
