Hi Christof:
I am afraid I don't quite understand your question. Do you mean by
a clef change by Ct at the very beginning the _very beginning of
a movement_ of, say a piano piece? And in that case, you would want
the piece to nevertheless start _with the usual piano notation of a
bass clef for the left hand_ , but switching to treble immediately
(as demonstrated in my silly example attached)? I must admit that
I never saw anything like that in the literature [I am not a
pianist :-( ], so I can't answer the esthetic part of your
question (if that _was_ indeed your question).
On the technical side, PMX does ignore the extra Ct in that
case. You can, of course, trick PMX into doing what you want, as
in my example (the hard spaces included for graphic reasons ony):

Common practice, you say?  In my copy of Volume One of Schubert's
songs, Der Tod und das Mädchen starts with both hands in the bass.
No G-then-F clef.

Maybe accompanists have anyway to be more alert than soloists ;-)

 tenor clef. Likewise, one needs a change sign also within the peace

Sorry, I meant of course piece!

The clef can be changed probably simply by in-line text, but

It was an oversight. I never considered this case when originally writing
the code. I'll look into fixing it, but
please don't hold your breath as I'm preoccupied with Storace at the moment.
Meanwhile, Cornelius' hack is the best you can do, and it should work very
well. Since it only uses PMX commands, it doesn't introduce any space that
is hidden from PMX, so any PMX horizontal adjustments, e.g. for a crowded
accidental later in the system, will be accurately handled.

...one needs a change sign also within the peace

So should I include a peace sign in PMX ?

 if the signature or the clef change at the beginning of a new line,
 in this case at the end of the previous system.

At least I got this one right.
