Re: Using other NoteHeads with \harmonicByFret?

[Peter Crighton]

No, unfortunately it doesn't have the desired effect.
First, there was a "$" missing before "fret" in the "\override
TabNoteHead" line.

But then, it does override the NoteHead for every following note, that
does NOT have \mixedHarmonicByFret in front of it. All
\mixedHarmonicByFret notes still have harmonic NoteHeads.
I then added a \revert NoteHead #'style after the other \revert line,
but then it works like the normal \harmonicByFret, so no
harmonic-mixed anywhere.

I'm trying to figure this out, but don't have more ideas right now…
