I recall answering that post. My proposal is to use direct postscript
for the ledger lines, using a rounded pen, and have both thickness and
roundness adjustable. I fear that a mix of rules and characters would
lead to alignment problems.

Yes, but since output still goes through TeX, the 256 char limit still
is an issue. Yes, we have direct PS output, but I think it doesn't
work well enough out of the box to suggest this as an option. Either
we start working on direct PS output, or we figure out how to do the
switch to parmesan, or figure out how to address >256 fonts.

Also, IIRC, PS encodings are also 256 chars and larger fonts require
some trickery somewhere. Don't know about the details, though.

There are no real plans to improve this; I recently changed font-name
and added font-magnification, though. Probably currently the best
option is to encapsulate ancient formatting instructions into an
indentifier, and add

    medicaStyle = {
    \property Voice.NoteHead \set #'font-series = #'ancient



to the settings.

Yes -- complete, working features are always more appealing to the
masses. There are already too many half-working features.
