Chapter 16 Score Editor 509
This method applies not only to the first staff, but for all staves. However, if the piece
already contains other key signature changes, any newly inserted key signature only
changes the key from the insertion point up until the next key signature change. As
with the starting key signature, inserted key signatures affect all Regions, on all levels.
Deleting a Key Signature Change
This is done by either clicking directly on the key signature change with the Eraser tool,
or by selecting it and pressing Backspace.
Moving and Copying Key Signature Changes
Since key signatures are global symbols, they cannot be moved or copied as easily as
other objects.
Further editing of time signatures is possible with the help of the Time/Key Change List
Editor (see “Time and Key Signature Editor” on page 165).
It is also possible to copy all time and key signatures from one song to another. This is
described in the section Copying Time Signatures between Songs (see “Time Signature
and Division” on page 91).
The display of key signatures and key signature changes also depends on the settings
in Layout > Clefs & Signatures (see “Clefs & Signatures” on page 567), and on the Key
parameter in the Score Style window for each Score Style.
Time Signatures
Time signature changes can be inserted at the beginning of any bar, either by inserting
signatures from the Part box, or by changing the time signature setting in the
Transport window. In the latter case, the signature change will be inserted at the
beginning of the measure containing the current song position.
Time signatures and time signature changes are effective globally for all instruments,
on all display levels. It is not possible to insert different time signatures for different
instruments, or tracks. Time signature changes affect only the display, not the playback.
The tempo indication in the Transport window always relates to quarter notes, even if
eighth notes are chosen as the denominator for the Time signature. You can find more
information about this in the section Time Signature and Division (see “Time Signature
and Division” on page 91).
