Hi Tim,
That's weird, because I didn't have any problem changing the volume of a particular staff, exporting the .mid, and then re-opening the .mid (making sure it wasn't the original .not) to see the correctly changed volume levels.
Here's how I did it - maybe there's something I'm doing differently which doesn't show the problem.
1. Open the .not file you posted.
2. Use Staff/Setup to bring up the big dialog of staves.
3. Set the volume of the first staff to 127.
4. Click Ok to save the change.
5. Use File/Export as MIDI, and append something to the name
so I won't confuse it with the original file.
6. Close the original file, and open the exported .mid file.
7. Use Staff/Setup to view the volume settings for the staves, and the edited one has saved correctly, as well as the others keeping their previous volume settings (ie, they didn't all change to 96).
What should I do differently to make the problem show up?
Thanks!
Sherry
