Hi,
You've definitely been putting Composer through it's paces! That's a lot of work that you've done to a really complex file (which started out with no regard whatsoever to barlines nor time signatures) - well done!
Regarding the bug problem, thanks for including both "before" and "after" files - that should prove helpful in tracking down the problem(s). I've written it up and have both files on hand.
For your continued work, though, here's what I'd recommend trying.
- Delete any staves that you no longer need. In other words, include only the staves that you want for further work.
- Now use File/Export MIDI (rather than the typical "File/Save as") and give it an appended name to help you remember where you were in your work. This will export a .mid file of your work, and eliminate any "junk" that has been created in the .not file as part of the bug. I don't see any annotations or such, so you won't lose your already-done work, just the junk
- Now reopen the saved .mid file and continue with that.
Thanks again for the report - this type of reporting helps us make things better!
ttfn,
Sherry
