[sdiy] Piano physical modeling

[Rkm]

The finite difference method PDE stuff isn't too bad, it just takes me a while since I don't do it often.  

I read a good paper for a differential equation modeling of the moog filter a few years back (by Antti Houvilen I think?). I implemented it in JS (an audio plugin language for the Reaper DAW).  If I can find it, I'll share.

I would love to be able to quickly change hammer materials/positions, or apply mutes at harmonics or near the bridge, or simulate driving the strings with magnets and an external signal, etc.
