Question

I see, Notion can write 4 voice on piano. But i have sometimes 5 voices with different pulse in every voice. How write it?

Answer 1

Notion 6 will only allow you to write 4 voices per staff.  If you are working with a grand staff, you can write 4 voices into the treble clef and 4 voices into the bass clef.  This gives you a total of 8 voices for the grand staff.
