Why didn't it, Chris?  That's the part I don't get.  Going after this with a 
grid quantize should have trashed the human aspect of the performance, but 
left everything lined up on neat lines.  It didn't seem to change much of 
anything, and I think there's another bug here.

IF the quantizer worked.

Your fix in LilyPondExporter seems to deal with the first problem reasonably 
enough.  I'm almost as bad as you are at really testing anything, but it 
passed the test case in question, and a couple of random snippets I dug up, 
and the change seems logical enough.  I wouldn't have thought we could still 
have a bug like that in code that thoroughly tested for so many years, so it's 
pretty amazing to discover a nugget like this.

What about quantizing though?  I never could use any combination of quantizers 
to get that original performance lined up mechanically on precise boundaries, 
which is always my first approach to dealing with an especially human passage 
that just come out properly.

I guess in my real world use, once in awhile I hit a few bars that I have to 
erase and draw by hand.  Maybe none of this ever worked very well, and it just 
happened that the sample piece we just looked at was an entire recording 
showing the same characteristics as what would typically only be a bar or two 
in the middle somewhere.

Who knows.  It's kind of troubling, but I'm also no longer in a very good 
position to try to think about or do anything about stuff like this now.
