Casio CZ/ VZ/ FZ - Pro Series

Jon,

 that's an excellent analysis. I agree on all points...
Except now I find myself wondering why the _exact_
shape is important at all... I'm sure the perception
issues are important, and that for different kinds of
sounds the perceived volume changes will be sort of
different... So after all, why not use our ears
when adjusting the enevlopes and such?
