Hello,
I have a large film score (1200 measures) that I started in Finale and imported via xml. The first time I inserted a split flow, I had no problem. Looks great. Upon the second inserted split flow, I lose about 75% of the music after the split. I can’t determine why some music disappears and other music does not, but it is always the same passages affected.
I tried splitting in different places and also inserting a blank measure and splitting after the blank. Same result no matter where I try.
This screen shot shows the piano part before and after the split flow is executed. (Thankfully “undo” is working well.)
