Neil thank you for the confirmation and quick reply. What I did leave
out in my message was that I'm trying to get my transpositions while
using the makam.ly file for Turkish music. What I get often are
warnings that glyphs don't exist for such and such alteration for
example one warning says:

"no glyph found for alteration: 7/18"

I'm not even savvy enough to figure out how lilypond came up with that
number (in this case it's asking for the glyph that shows a 4 koma
sharp character...4/9).

By the way, transposing Turkish music on paper in general is
irrelevant for most Turkish classical musicians since transposing by
sight is very common. However a highly practical application for
transposing Turkish music would be to make it readable for Arabic
classical musicians...Arabic music in general is written a 5th below
where Turkish notation sits.

Any more thoughts from anyone?
