Key Signature Symbols in the Part Box
Key signatures inserted in the Score Editor (or global Signature track or Signature List)
affect all instruments on all display levels. This is reflected both visually and in MIDI
playback.
Natural symbols are automatically displayed with a new key signature, when necessary
(when changing from A flat major to F major or A major, for example).
The display of key signatures and key signature changes depends on:
• The Score project settings in the Clefs & Signatures pane (see Clefs & Signatures Settings ).
• The Key parameter in the Staff Style window (for each staff style).
Detailed information about key signatures can be found in Working with Time and Key
Signatures .
Time Signature Symbols in the Part Box
Time signatures inserted in the Score Editor globally affect all MIDI regions, on all display
levels. Time signature changes affect the display, but not playback.
