Add and delete staffs or voices in the Staff Style window in Logic Pro for Mac

You can add staffs to a staff style, allowing you to create a two-staff piano style from a single-staff style, for example.

A staff can display multiple independent melodic lines, called voices. Some predefined staff styles display only a single voice, while others can display multiple voices (these are called polyphonic). You can choose polyphonic staff styles to display multiple voices (for choirs or polyphonic instruments), and can add voices to a staff style to display independent lines. Theoretically, a staff style can display up to 16 independent voices (but this may not be readable).

You can also duplicate staffs or voices.

Each staff is represented by an ID number. The ID numbers are assigned automatically and cannot be changed.
