The display of time signatures and time signature changes also depends on the
settings in Layout > Clefs & Signatures (see “Clefs & Signatures” on page 567).
All time and key signatures from one song can be copied into another song (see “Time
Signature and Division” on page 91).
Repeat Signs and Bar Lines
These objects can be inserted at any “visible” bar position ( at the position of any
graphically displayed note or rest). Usually, however, these objects are used at the
beginning or end of bars. In this case, they replace the regular bar line (except first and
second ending symbols). They are global symbols, so they always are displayed in all
staves, on all display levels.
Moving, Deleting
Repeat signs and bar lines cannot be moved with the mouse. To delete them, you need
to use the Eraser tool. These symbols can be moved, together with time and key
signatures to a certain extent, in the Arrange window (see the two preceding sections).
The “double repeat sign” automatically is displayed as two “back to back” repeat signs, if
it is positioned at a line break.
Invisible Bar Lines
The dotted bar line becomes invisible in the printout. In conjunction with hidden time
signature changes, this enables you to create bars and musical passages which
seemingly do not have a fixed meter. Another use for the invisible bar line is to force a
graphic split of a note into two notes connected with ties, in all staves of a score
simultaneously, if it is inserted in the middle of a bar.
To hide all automatically displayed barlines of a song, there is the option Hide All
Barlines in Layout > Clefs & Signatures. However, manually inserted barlines, double
barlines and so on will still be displayed and printed.
