I don't understand very much what is written within the page you sent me. But from the
"quick start" I have understood the basic and was able to implement this code:

It works. Unfortunately I can only re-name the existing standard notation.What about
adding arrow-"ed" accidentals to the already existing ones?
I can read on the "accidental" paragraph of the web-page you have provided:
"Whether or not you want new accidentals, you need a new associative array for
microtonal tunings."
