So we want to fix up musixgre. The four things Elie has identified as missing
in MusixTeX are included in opusTeX
1. Episema \episema with two arguments, one for pitch the other for length in
notewidths
2. Special bar lines: \divisiominima and \divisiominor (might also consider
\virgula)
3. Custos \custos with one argument for pitch followed by \lineaproxima to make
a new line
4. The flat (\bmolle) and maybe the keysignature version \bgenerale
You can see how these are coded in opusgre.tex and opusggen.mf. The
00readme.txt says you can't change these files, but what about using bits? I
suspect there would be a bit of work in getting them to work with MusiXTeX.
Elie hasn't mentioned the problem of aligning lyrics in under the chant.
OpusTeX allows you to align the vowel of each syllable under the neume, whereas
musixlyr would centre the whole syllable. For example in Opus the syllable
`Chri-' would be coded as {Chr}i- and the `i' would align with the neume,
whereas musixlyr would centre the syllable and the `h' would be the closest to
the neume. Would I be right in saying that this is the big difference between
MusixTeX and OpusTeX for gregorian chant?
Most people looking for a way to do Greg chant well in TeX just use OpusTeX and
the licence doesn't matter. I'm a bit concerned about the licence if its going
to prevent development. At least Don Knuth's TeX files say IT MUST NOT BE
MODIFIED IN ANY WAY UNLESS THE FILE NAME IS CHANGED! Could we have a subset of
OpusTeX available that just did Gregorian Chant (no beams necesary)? Maybe a
changeable version so odd neumes could be added like torculusresupinusflexus.
It's my hazy understanding that these can't be added so easily by new .tex
files because of the definitions with @ in them aren't global (does any one
understand what I mean here?)
