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

http://otl.stanford.edu/tech/sondius.html
http://news-service.stanford.edu/pr/97/970708staccato.html
http://news-service.stanford.edu/pr/97/970709sondiusxg.html

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.
Tom
