well, thats not what they are teaching in engineering school these days!
They say that (loosely quoted from textbook) "Any sound can be broken up
into its harmonic series using fourier analysis. Once these basic
frequencies and amplitudes are known, then, all that needs to be done to
replicate the original sound is to do a time domain analysis of the
amplitude changes of each of the various harmonics."

BUT, it IS possible.. there used to be a program for the atari ST that
would take a sampled sound and break it down using fourier analysis and
turn it into sysex and send it to the ol Kawai K5.. I believe it worked
on the dx7 too..mind you, the replication of the samples were often
terrible, but some were very close.

Actually, the first generation attempt was the mellotron (sampling) and
FM additive was the second.
But, now Im sounding like a know it all dickhead, sooo..  :))

whatever!
