Hi all,

A few months ago I posted a message looking for advice on creating piano
sounds that contained the proper damper pedal harmonics, and harmonics
generated when multiple notes are sounded.  Didn't really get anywhere
in my search for a better synthesis model, so I'm wondering what
harmonics would need to be added to a sample playback type synthesis? 
This doesn't need to sound convincing to a classical pianist, just
something that sounds to me noticably "richer" than the plasticy sound
of a sampler.  If I play note A, it produces a harmonic series that
evolves over time, which sounds fine to me on a sampler ... but if note
B is played simulataneously there is some interaction in the harmonics
that I have no idea how to model.  The reading I've done on piano
synthesis has been too much mathematical theory, which is a bit over my
head ... so my question, I guess, is from a practical standpoint how
does one determine the interactive harmonics and produce a decent
approximation of them without reverting to physical models (which are
far to primitive at this point). 

thanks
