No, LilyPond has its own fonts, Denemo has got two of them feta.ttf and
emmentaler.ttf in its own distribution which it uses for the Denemo
Display. If you look at 

Help->Browse Feature Packed Score 

the last movement of that score shows the glyphs from the LilyPond
fonts that Denemo can display. However the LilyPond fonts that Denemo
has are not, I think, the most recent versions of LilyPond's fonts.
Denemo only has them to let the user know see an approximate typeset in
the Denemo Display, it is LilyPond that does the actual typesetting
with its up-to-date fonts.

is as much as I know. The LilyPond mailing list lilypond-u...@gnu.org
is extremely active and the folk there would know all about LilyPond
and fonts. In particular, if you post an example showing the range of
microtonal symbols you want to typeset they will be very eager to
develop simple samples of LilyPond syntax that does what you want.
Armed with that you might want to tell Denemo to generate the syntax
needed, but that is the second stage.

On Windows especially the first time you run Denemo it can spend an
extraordinarily long time caching fonts - the feta and emmentaler fonts
are designed with different glyphs depending on the final point-size
required and there is a lot of work goes on the first time LilyPond is

I presume you mean the very latest version 2.2.7? This will not make
any start icon I think, because it is not installed, it can reside
entirely on an external USB stick etc. Did you notice if it left a
black console window open while the program was running?

Is that to say you made a palette button that would run the script I
sent when clicked?

It is LilyPond's syntax for a note, everything except the note name is
optional, the defaults being the natural accidental, the octave below
middle C (unless in relative mode when the default is relative to the
last note) and the duration of the last note. LilyPond reads this and
decides what should be typeset. By including "makam.ly" LilyPond
expects "k" as a possible accidental and will typeset the glyph it has
for that.

Python is not used in LilyPond itself, only some converter programs
like midi2ly and so on. The parsing of LilyPond syntax is handled in
C++ and Scheme. But, again, this is not the mailing list for LilyPond
questions - anything you read here may be just a fuzzy understanding of
LilyPond, there are a dozen or so experts on the workings of LilyPond
on their list, only too happy to see more music typeset by LilyPond.
