  I believe the patents developed at Stanford, if I remember correctly about 
400 in number, was known  as Sondius. Anyway here are some  links:


How much of this made its way to market through Yamaha, I do not know. I 
believe the " YMF nnn " series of chips had some this in the firmware. I 
suspect that this may have been part of the problem in Linux audio to really 
support those cards. As I understood it, was while most of the market was 
relying upon samplings, the Yamaha chips were dynamically sound synthesis.
These presumptions, may be not correct.
Hope this helps.
