If you have already created some Tracks which look and play back as they should, and you want to combine these into one Track with polyphonic voices, there is a special function on the Score menu for this:
1. Open the Tracks (up to four) in Score Edit.
As previously described, you could either select the Tracks in the Arrangement first, or add Tracks to the Score Edit display using the Display Tracks feature.
2. Pull down the Score menu and select “Merge All Staves” from the Staff Functions submenu.
Now a new Track is created and added to the Score Edit display. The Track will have Polyphonic Voices activated, and the four original Tracks will be assigned to one voice each (voices 1, 2, 5 and 6 will be used).
Furthermore, all non-linked symbols, that belongs to the staff that will become the first polyphonic voice in the merged staff, will be copied. They will have same positions as the original symbols.
P When you later play back the music, you need to mute the four original Tracks, or you will get double notes.
