Suggestion is to clarify use of the Fold button on p15 of the BBMO user manual with words to the effect: “Use Unfold view when transposing notes so that the screen displays properly.”
macOS 26.2
BBMO 2.0.4 using Vivaldi for an OPB song
Notes are in Fold mode
Steps to reproduce :
Open an OPB song in BBMO 2.0.4
Click Fold button
Use the Quick select instrument to highlight all of the notes in the row for an instrument
Move the note down or up (one semi-tone); expected behavior is for the display to show the transposed notes in it’s new position; instead the screen jumps downwards several octaves
I’ve labeled this an anomaly as this does not happen when the view is Unfolded
