Mahar, I'm not certain what it is that you are refering to as far as Yamahas ownership with respect to FM sound generation. As far FM patenting is concerned, John Chowing of Stanfords CCRMA is the one who, perhaps didn't conceive of the idea, actively purued and developed the process of Frequency Modulated Sound Generation. The same John Chowning, not Yamaha, is the one who holds any patents having to do with FM Sound Generation. Doug Donahue AT&T Information Systems attunix!dr_d
