Editing Repeat Signs and Bar Lines in the Score Editor
Repeat signs and bar lines cannot be moved with the mouse. You can, however, move
these symbols (along with time and key signatures) to a certain extent, in the Arrange
window.
Once a region is selected in the Arrange window, alterations to its end point (or position)
will affect existing repeat signs and bar lines in the score. Inserting, deleting, and moving
key or time signatures in the Arrange window global tracks also have an impact on these
score elements.
To delete repeat signs and bar lines
µ Click them with the Eraser tool.
Hidden Bar Lines
The hidden bar line symbol is not visible when you print the score.
Normal bar line
Hidden bar line
Using hidden bar lines in conjunction with hidden time signature changes allows you to
create bars and musical passages that don’t seem to have a fixed meter. Another use for
the hidden bar line symbol is to force a graphical split of a note into two notes connected
with ties—in all staffs of a score simultaneously—if it is inserted in the middle of a bar.
Logic Pro includes a preference to hide all automatically displayed bar lines. Manually
inserted bar lines, double bar lines, and so on will still be displayed and printed, regardless
of the preference setting.
To hide all automatically displayed bar lines
µ Select the Hide Bar Lines checkbox in the File > Project Settings > Score > Clefs and
Signatures pane.
