Editing Single-Staff Polyphonic Styles
(With Several Independent Voices)
Polyphonic Score Styles are needed when rhythmically different melodic lines should
be displayed in the same staff. Theoretically, up to 16 independent Voices are possible.
There are two possible ways to add another Voice to a staff in the Score Style window:
• Menu New > Insert Voice. The new Voice will be inserted at the position of the insert
mark (>), which can be set with the mouse in the narrow column to the left of the
staff numbers. (This is important if you want to insert a new Voice between existing
Voices)
• By clicking with the Pencil tool into the (empty) lower right portion of the Score Style
window. In this case, the new Voice is simply added at the bottom.
In both cases, the newly inserted Voice will have the same parameters as the Voice
above it, which can now be edited.
For every new Voice, a new line appears in the Score Style window. For additional
Voices within the same staff, it is important that the staff field in the first column stays
empty. If a number is displayed there, click on it. This will cause the number to
disappear, and the corresponding staff to disappear from the Score display.
If there are two independent Voices throughout the piece, the parameters might be set
as follows: Stem, Tie, and N-tuplet direction are set to up for the top Voice and down
for the bottom Voice. Note that even with these general parameters, these Note
Attributes (see “Note Attributes” on page 548) can be changed for each note. Both
Voices are displayed with automatically displayed rests (Parameter Rest: Show).
For Voice Separation (see “Voice Separation Method” on page 538), the same methods
as used in two-stave systems can also be applied. Either draw a line between the notes
with the Separation tool, or edit the MIDI channels of the notes directly, according to
the Voice assignment in the Score Style window.
While the Voice Separation tool is being used, the help tag shows which of the Voices
are being separated in the current process. This is indicated by two horizontal arrows
between the numbers of the Voices, and is only relevant if there are more than two
Voices. To switch to the lower Voices, the arrows can be moved with Shift while the
mouse button is pressed.
