Yamaha CS80

I want to publicly thank Juergen Haible and Scott "Crow" Rider for having enlighted me about the Expression circuit and about some aspects in the touch response.

BTW: I found many patents about the CSs and GX1 on the USPTO site, it seems that the work involved many people, there are different sources for the KAS, the Touch response, Expression circuit etc, surely Tetsuo "Phil" Nishimoto is among them, he's responsible for the Touch response patent.
