This question seems to come up every few months on this list. I won't say,
"It can't be done," as "can't" is clearly in the eye of the beholder, but ...
Analog and analog-modeling synthesizers use simple waveforms (saw,
triangle, pulse, etc.) and filtering to create complex sounds. The
resulting approximation either succeeds or fails based on the level to
which the original and copy waveforms can be made to look alike: In the
case of say, a Trumpet, the raw waveform is rather sawtooth-like, so a
decent copy can be obtained by filtering a sawtooth wave using analog
methods. Piano is another story, however.
Commercial piano products using simple waveforms from companies like RMI,
Univox, and even Roland and Yamaha were all the rage in the
mid-to-late-70's. It soon became obvious, however, that the results were
less than stellar. The waveform of a piano is rather complex, and
resembles none of the base elements of classic analog synthesis. No
"reasonable" number of standard analog waveforms summed together can do it
justice, IMHO. It might be possible to create a decent piano copy by using
multiple analog/modeling synths -- one to simulate the hammer attack,
another for the basic tone, a third to add the bright sound of a hard
strike -- but why bother, when sampling keyboards have been tweaked to the
point where they are both cost-effective, and more than adequate for many
piano needs?
A similar attempt occurred when FM synthesis came on the scene, with
similar results. Again, with enough synthesizer horsepower, acceptable
(but far from perfect) results could be found, but a single instrument was
unlikely to have enough elements to simulate the complete sound -- or if it
did, as in the case of the Yamaha DX1, the amount of programming necessary
to arrive at the desired end was prohibitive for all but the most tenacious
(and financially sound) programmers.
There are many wonderful sounds that can be coaxed out of the AN1x;
acoustic piano just isn't really one of them.
Just my $0.02US ...
