I had to do this myself sometime recently. The following is what Werner Icking
wrote in response:

AFAIK it's not possible with PMX up to now. So you have to do one of
the usual tricks. In the second case "c4x3 r d":
\\let\qbsav\qb\
\\def\qbtods{\def\qb##1##2{\zcharnote{##2}{~}\ds\let\qb\qbsav}\
...
c4x3 \qbtods\ c d ...
That means replace \qb by a new \qb which generates a \ds; in addition
it generates an empty text using \zcharnote, if the pitch in #2 does
do any change in the octaviation; then it restores the old \qb.
The first case is more sophisticated, because the start of the beam
\ib... has to be ported to the next note :-(
In some case the problem can be fixed by blind meter changes. But then
you have to suppress the barlines.

(But if you can cope with the beam extending over the first rest, the fix works
for this case as well.)
There is a lot of helpful advice on the mailing list archive:
http://www.gmd.de/Mail/mutex-archive/
but I realise it's not always easy to find things, as the archive is now rather
large :)

now *this* I don't know how to do - and it's something I would like on
occasion. (starting a beam in one hand, and finishing it in the other, for
example). Any ideas, people?
