Re:some simple physical modelling

Hey Matt,

How about allocating a separate buffer to each track?  Your code doesn't include
provisions for multiple tracks yet, but when you add it I think the problem will
take care of itself.

I mean, when you pluck a guitar string twice in a row, it cuts itself off, so
from one standpoint, having multiple plucks within a given track cut each other
off makes more sense than not -- basically it makes the analogy that each track
models one string.  If you want to properly emulate a six-stringed instrument,
say, then you use six tracks.

Dunno if this is how Geonik's machine works (haven't used it enough to have
noticed) but it makes more sense to me than dealing with multiple buffers.

SimpleString is a simple plucked string synth.  It uses the
Karplus-Strong physical model with damping.

It's almost identical to Geonik's Plucked String synth for Buzz, but
with one important difference:  new plucks will cut off older ones. 
I've thought of two ways (that don't involve allocating memory on new
plucks) to fix this:

1.  Allocate 16 or so buffers, and assign new plucks to them in some
method.

2.  Assign a buffer of the correct length (samplerate / frequency) to
every note, then poll each every time ox_work is called.

Neither seems like a particularly good method to me.  Am I just being
too picky, or is there a better way?
