RE: Unconventional score and unwanted stray staff lines

[Mark Stephen Mrotek]

David, 

My experience is transcribing 18th and 19th century piano scores.
I do get "run-off" staves. 
This is usually the result of incorrect mensuration of a note or notes.

You piece still has some sort of vertical simultaneity.
Perhaps you could start with a temporary time signature, just to see if voices 
align.
Then remove it for publication.

Hey Mark,

> Maybe use bar checks?

Given that a lot of the music isn't generated to fit any particular time 
signature (ie, the bar lines are often there just to break things up to ease 
reading), I would get tons of bar check errors. Plus, keeping track of when 
bars should be inserted in my software seems like it would be a huge chore. Is 
this something you think would solve the problem?
