Using the spacing of the "Way-after" grace note is a really clever
touch! But here are a few comments:
(1) In my own experiments, placing \caesura\ after the last note of a
bar has the same effect as placing it before the first note of the next
bar, provided there is a next bar in the same input block. In Neil's
original example he terminated the input block after the end-of-bar
caesura and it was completely ignored.
(2) According to the definition of \caesura in musixtex.tex, the symbol
is left-offset by 0.5\noteskip from the insertion point. To get the
desired position you could insert it on the prior note and rightshift
it, or if you put if on the 1st note of the next bar and move it as
desired, e.g.
e04 o_+10 \loffset2{\caesura}\ | e4 o_+10 e4 o_+10 e4 o_+10 e4 o_+10 |
e2 e2 /
(3) When I run Alexander's example I get two caesura's, touching each
other so they look like one thick one. The explicit \caesura\ is showing
up, 0.5\noteskip to the left of the first note in the second bar.
(4) If you want to use or adapt Alexander's suggestion, for safety you
should probably save the original definition of \grcu and then redefine
it back to the original after you use it.
(5) Alexander's solution does not give the proper positioning if used in
the middle of a bar. That's because the "way-after" grace note is
handled differently at the end of a bar, where it is inserted from
within a \znotes, which sets \noteskip=0pt. When used in the middle of
a bar, \noteskip is not zero and \caesura offsets the character by
.5\noteskip as it normally does.
Since this has come up several times already, I suppose I should
consider including the \caesura as an ornament in PMX (even though I've
never had occasion to use it myself).
