No, that's all far more complicated than I was intending. I was more
thinking that playing two notes of the same note should be synced. If
note 1 is already playing, and then note 2 is struck (the MIDI event)
then look at the fundamental frequency of these notes and delay the
start of the second note's samples until they would play 'in sync'
with the first note's samples. In this way I was thinking the first
and second note would be more 'supportive' of each other, and in some
ways more like I'm guessing the real string works.

This works for the case where the first note is loud and the second is
soft. However, when we turn it around it's not so clear what to do. If
you want the two to be in sync, then do you play the second one a bit
late again? Or do you play it right away?

My thought is to play them all second notes just a bit late to
guarantee sync between any notes of the same value.

this is all programming trick. I'm not talking about changing anything
fundamental here. All we need to know is the apparent fundamental
frequencies of the notes, but even this may not be obvious, or may be
weird when we add tuning to the tool sets.
