Problem: Use “8va ledger lines” in BB for high register notes.
Solution: 1) enter desired note as it should be heard, but make it “invisible”.
2) enter another note in the same place, but one octave lower, and make “velocity = 0”.
3) enter "8va----|" in text (as lyrics) above the invisible notes.
The lower note will be displayed and not heard, and the note an octave higher will be heard but not displayed.
