I've exported my session to a .mid file to open in Sibelius and the second half of my project shows as empty in Sibelius. So i tried it in Presonus' notion and it's the same thing.
My session is one cue about 2 mins separated by 2 mins silence then the big 4 min cue. The latter just showing up as empty bars in both notation software. What could account for this??

All the time signature changes and marker heading are there but no note information at all!! I'm at a loss This is kind of an emergency as i have to get this recorded with players.

Thanks in advance. Haydn.
