Note: If you perform this procedure when the track height is reduced, a time signature
change is created.
• The Beat Grouping text field allows you to determine the grouping of beats in
compound time signatures. It is sufficient to enter the numbers—223, for example.
This becomes “2+2+3” automatically. The total number of beats in the bar is calculated
automatically by the sum in this field. The Print Compound Signature checkbox needs
to be selected in order to display the defined grouping as the nominator. If not selected,
only the total sum is displayed as the numerator. Beat Grouping, however, affects the
way the notes are beamed together (in both cases). You can also change the automatic
beaming in normal time signatures. In 4/4-time “1+1+1+1” produces four beamed
groups (one for every beat), instead of the two groups displayed as a default.
• Select the Hide Signature checkbox to hide the corresponding time signature change
in the printout. The signature is still displayed onscreen, but is crossed out, and won’t
be included in the calculation of spacing between notes and symbols. As a result,
signatures may overlap notes on the screen, but not in the printout. This function can
be used for notating cadenza-like passages, which contain more notes than would
normally fit the time signature.
