So far I haven't been able to do this. I'm going to include some detail here in
hopes that Dirk will have a look at it and maybe point the way to a solution.
Before going into the details, note that there's always the ugly possibility of
creating two completely separate scores for the two different sections with
different numbers of staves, then merging them at the PDF stage.
But to do it all in M-Tx/PMX: I think you want to start with style Singer
piano (since you said 3 staves; organ gives 3 staves itself). This has 3
staves and 2 instruments. Then to change to (say) style SATB4 piano you'd
need 6 staves and 5 instruments. Unfortunately PMX cannot increase the number
of instruments beyond the original number. But that's not a show stopper
because you can start with a dummy, throwaway page having the maximum number of
instruments.
So to get started let's try to set up an mtx file that starts with SATB4
piano (for the dummy page) and then switches to Singer piano . Here's the
mtx I came up with:
=
Style: SATB4 piano
Meter: 4/4
Systems: 2
Pages: 2
% Need a dummy page up front, since PMX cannot increase
% number of voices beyond original value.
e4+ d c d | e e e2 |
L: Th-is is a dum-my page
c4+ b g b | c c c2 |
L: Th-is is a dum-my page
g4+ g e g | g g g2 |
L: Th-is is a dum-my page
c4+ g c- g | c c c2 |
L: Th-is is a dum-my page
c4 b c g | c c c2 |
c2 c | c c |
% Style Singer piano
% Need to put inline PMX commands BEFORE last line of
% first input group of new section!
e4 d c d | e e e2 |
L: Mar-y had a lit-tle lamb
e2 e | e e |
%% L2P2Mn215btt
c2 c | c c |
This produces pmx file

This does succeed in changing to the desired, reduced number of instruments in
the PMX file after the first system. But M-tx has added in some unwanted rp's
and has assigned the lyrics to instrument #5, not #3 as desired. It seems that
M-Tx is insisting on maintaining 5 instruments and filling in rp's for the ones
it doesn't find in the input file. I don't think there's any way to fix this
using inline PMX. Short of manually editing the pmx file, to fix things we'd
like to accomplish the following from within the M-Tx input file: (1) eliminate
the rp's; (2) change the last \\\mtxAssignLyrics{5}{11}\ to
\\\mtxAssignLyrics{3}{11}\; and (3) cancel out the effect of \\mtxTenorClef{3}\
. Without that capability, there might even be advanced in-line TeX that would
do (2) and (3), but I think (1) would require some sort of post-processing of
the pmx file.

Hi: I am trying to code O for a close Walk (SATB voices and organ) in mtx.
The first sixteen measures are for soprano and organ, and so requires
only three stave. Thereafter the style changes and there are 4 staves to a
system,
SATB and organ. Can this be coded in mtx, since there is only one preamble
to
declare the style? Does one have to go to pmx or musixtex to code this/
This can in principle be done with PMX by using the movement change
instruction.
It's not in M-Tx.
