woah... thats true but its a really small change... maybe not
even noticible. More likely is that as the string is played at
higher amplitude... the pitch goes sharper because the string
is, on the average... stretched more.
Worst part is that the harmonics of the truly 'stiff' string are
quite sharp. This causes some cycles to have multiple zero
crosses, etc. The fundamental pitch is correct, but may consist
of unequal (time) half cycles... one longer and one shorter.
woah now stick THAT in yer DSP... :^P

just processes it these days... er... with a synthesizer :^)
