Re: Transpose notes when changing treble to bass clef
So immediately after your treble clef, press K for insert key signature, and select C major. That will insert a natural sign on the top line F, with a visibility setting Never (in other words, it won't print).
The visibility setting will be whatever the visibility setting was the last time you inserted a key signature in the same session. For the first time, it will be Visibility:Default.
Visibility:Default is not the same as Visibility:Never! For a key of Signature:C, none of the visibility options will produce any ink, but they cause different spacing, which can easily be seen here:
!NoteWorthyComposerClip(2.0,Single)
|TimeSig|Signature:2/4
|Bar
|Key|Signature:C|Visibility:Never
|Note|Dur:Half|Pos:3
|Bar
|Key|Signature:C
|Note|Dur:Half|Pos:3
|Bar
|Rest|Dur:Half
!NoteWorthyComposerClip-End
Yeah, I know. Picky, picky ...
