[JW Lua] Note displacement

[Mr.Pat]

I'm using the following to get the vertical position of a note on a staff.

 

Region = finenv.Region()

for fcnoteentry in eachentry(region) do

   if fcnoteentry:IsNote() then

      for note in each(fcnoteentry) do

         offset = note.Displacement

         print (offset)

      end

   end

end

 

The documentation says:

 

0 is middle C. Positive values is above middle C, negative is below.

 

All is well in C Major but things go south for any other key. Most often the
displacement is relative to the tonic, but an octave off. Sometimes I can't
even figure out where the number comes from.

 

Any ideas on what I'm seeing or what I'm doing wrong?

Pat
