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.
