Dear Stefan,
Sorry for my late reply.

I was able to try out the example. There is one not convincing for me:
The default accidental is an natural. But I would like to use fis

You can easily switch to the standard Lily accidental treatment where
the HE accidentals are then supported additionally. Quote from the
Readme file of the HE-Lily.zip file I just sent:
Note that this code completely disables the common Lilypond
accidentals, because the spacing (and to some extend also the
shape) of these and the HE accidentals differ considerably. In
order to allow for the common Lilypond accidentals anyway, comment
the three Lilypond code lines in the score layout section that set
accidentals to be written written as markups by default and sets
the default HE accidental.
Nevertheless, I feel in most situations you actually want an
accidental for every note (including naturals) in order to avoid
misunderstandings. In fact, the published scores using HE notation
tend to do this.
Wouldnt it a possibilitie to define new pitch-names, like it has
been done in the makam.ly?
But how can this be done?
As far as I understand, the approach of the makam.ly example allows
only for one single accidental per note. Question to the Lily-gurus:
is that actually correct?
With the HE notation however, you can theoretically have an arbitrary
number of accidentals per note. For example, a single note C sharp may
be raised by two septimal commas and flattened by a 11-comma, so you
have 3-4 (!) accidentals that are assigned to a single note head (the
2 septimal commas can be drawn as 1 or 2 accidentals). Also, in just
intonation you have an unlimited number of different pitches in
principle. So, you would need an unlimited number of different note
names if you want fully generic support. At least you would need a
pretty large number of note names, even if you only want to cover some
subset of the pitch lattice. For example, if you allow for only up to
2 Pythagorean accidentals in each direction, 3 syntonic commas in each
direction (HE has special single signs for these), up to two septimal
commas, one 11-comma, one 13-comma, one 17-comma, one 19-comma, one 23-
comma etc., then the required number of note names is the number of
all possible combinations of these times the seven nominals C, D, E, F
and so forth. So, we would need (if I get this math right, others are
welcome to correct :)
5 (Pythagorean accidentals) * 7 (syntonic) * 5 * 3 * 3 * 3 * 3 * 3
(etc.) * 7
= 297,675
different note names. I feel this number of note names gets impractical.
I therefore feel the approach inserting some \HE <accidental-string>
is more generic and still pretty concise.
Best
