Thank you Hans, Gregory and Jean,

Your help is precious.

Just another beginner's question:
I found amazingly that Lily plays the 1/8th tones correctly as it does for 1/4th tones.
If i need to use other weird scales, can someone point me to the lily code responsible for the midi pitch tuning (bend) in lilypond, so I can mess around ...

From LilyPond's point of view, every note has a pitch, and this pitch is played strictly, that's it.

In the code I sent, the 1/8 tone intervals are played correctly because I defined the pitches "cet", etc., with the values they should have, using ly:parser-set-note-names. You can do that too, like in the following example; you also need to define accidental glyphs.

\version "2.25.2"

#(ly:parser-set-note-names
  `((mynoteA . ,(ly:make-pitch 0 0 1/14))
    (mynoteB . ,(ly:make-pitch 0 0 3/14))))

\layout {
  \context {
    \Score
    alterationGlyphs =
      #'((1/14 . "accidentals.sharp.slash.stem")
         (3/14 . "accidentals.sharp.slashslashslash.stemstem"))
  }
}

{ mynoteA mynoteB }
