http://trademarklawbriefs.com/?p=48

but yamaha Copyrighted his styles:
http://www.global.yamaha.com/news/2008/20080508.html

so, yamaha styles are copyrighted but not the yamaha file extensions, so user can use if they pay orginal yamaha or ketron style with ketron or yamaha hardware or third party software. if they create own styles in yamaha or ketron format they are free to use it with yamaha or ketron hardware or thirdparty software that can work with this 2 brands style extensions.

maybe i read it again wrong!!!!!!!
