Hi Scott,

Nice sound, always good to try new synthesisforms with rich sounds.
Thinking about the string simulations I did back in ´98 or so and
elaborated on later (see http://www.theover.org/Articles/pms.html), I´d
think you´re into issues with the Karplus/strong where both the
noise-type excitation and the way of propagating the sound aren´t too
optimal for harp, but very nice sound though.

Have you tried a Spartan 3e-500 version, too by any chance ?

Greetings
