I see it now: black_notehead_width is defined in line 349 of
feta-noteheads.mf, it is also mentioned at the end of that file.
Unfortuantely it's not defined using some given value (or explicit
formula), but as a result of glyph drawing operation, namely drawing
black notehead.
(In other words: variable black_notehead_width depends on how notehead
is designed, not the other way round.)
Because of that i don't know how to extract this value from
feta-noteheads to feta-flags, my knowledge of Metafont is too limited
:(
Does anyone know how to do this?

thanks,
Janek
