Jan,
I finally got a chance to try it out, and you are right. In this case the
slot and staff numbers are the same, but that is not guaranteed. As you
suggest, It must have something to do with the channels that the staves are
mapped to. There are only 5 in this case. I don't see anything in the
Class Browser that looks like channel info. Maybe it's not implemented yet.
Jari will have to jump in here. Sorry I couldn't be of more help.
Charles

Charles,
thanks for your input ! But I am not sure, it does not seem to make a
difference here.
In the example I posted region.StartStaff and region.StartSlot both return
7 (and EndStaff== StartStaff, EndSlot == StartSlot), but it should be 5 to
work properly.
Or in code:
region = finale.FCMusicRegion()
region:SetCurrentSelection()
print("Staff:",region.StartStaff,"Slot:",region.StartSlot)
This will print:
Staff: 7 Slot: 7
