No Time Signature
Notion supports scores with no time signature . This can be a significant help for you to jot down ideas without having to
stop to iron out meter counts, particularly if you will change meters often (you can concentrate on note/rest entry and
take the time to add separate time signatures later) .
Simply remove the existing time signature (click so it turns orange in color and press Delete) and don’t replace it with an
another signature . With this arrangement, since there is no meter to exceed, you can add notes and rests without having
to be concerned about measure bars (notes and rests do not turn red at any point) . Yet, Notion is still able to play back
your entry .
Courtesy Key/Clef/Time Signatures
Now Notion will add a cautionary key or time signature at the end of system if the key or clef changes on the next line .
These can be hidden by right clicking on them and selecting Hide End of System Courtesy . Courtesy clefs work
automatically .
