When I originally defined centered rests, it never occurred to
me that anyone would ever want to have two in the same staff,
or to have one together with another non-resting voice in the
same staff. Clearly I was wrong. I have started to fix this
several times but it gets rather tricky. Until I can teach PMX
to deal with this, in-line TeX is the best solution (Editing
the TeX file is not a good solution because every time you
change something somewhere else in the pmx file, you will need
to re-edit the TeX file; that is exactly why I activated
in-line TeX). You can simply override the definition of
\atnextbar using a type-3 in-line TeX string, e.g.
================
2 2 4 4 0 6 .000 0
0 4 20 .05
bt
./
c04 /
rp /
% The following two lines in the mail posting must be a single line in pmx file.
\\\def\atnextbar{\znotes\centerbar{\lower2\internote\pause}&\centerbar{\raise2\i
nternote\pause\bsk\lower2\internote\pause}\en}\
c03 /
c04 /
=================
This works because type-3 TeX strings are inserted into the TeX file right
before \xbar .

In-line TeX is the answer, but probably not by introducing
a bar line. Rather, you may want to re-define a particular
type of spacing note, e.g.
\let\hlt\hl\def\hl#1{\wh{#1}\let\hl\hlt}\ c25 |
(UNTESTED!)
I could make this more clear if you had provided a specific
example.

This should not be the case. Please post an example of the pmx
input. Slur definitions in two different lines of music in the
same staff (separated by "//") are supposed to be independent of
each other.
