Hi erik,
I will look at your EDSL. However, I am dealing with ties because I am 
converting a MusicXML document into a more natural form for my purposes. 
The initial form of the document will have tied notes (as it comes that way 
from MusicXML), and I want to convert that into a form that makes it 
possible to ignore ties and see notes as having a single duration.

Thanks,
Mike
