Hello there list,

I've recently discovered the joys of physical modeling and waveguide 
synthesis thanks to the csound book etc. (about 15 years late, I know!). 
When I search for PM on the internet I get a lot of results about the 
fact that Physical Modeling is still under patent.

I presume that I don't have to worry about this for making music using 
csound, and it is only if I were to make a piece of commercial hardware 
or software that I would be infringing patent...? Can anyone clarify 
this? It seems a slightly muddy issue! (Plus I don't want to spend the 
next three weeks getting a virtual drum to work if I'm not allowed to 
use it!)

Many thanks in advance for any advice,

Joe
