Re: SATB with automatic piano reduction - dynamics?

[Mats Bengtsson]

The problem is that \partcombine creates its own voices.
A simple solution is to keep the engraver and just make sure that no
dynamics are printed:
\override DynamicText #'stencil = ##f
\override DynamicTextSpanner #'stencil = ##f
\override Hairpin #'stencil = ##f

However, do you really need \partcombine? Often you can get very far with

  \new PianoStaff <<
     \new Staff { \clef treble \Key \Time
         << \sopranoMusic \\ \altoMusic >> 
     } % Staff
     ...
   >> % Piano Staff


or even 

  \new PianoStaff <<
     \new Staff { \clef treble \Key \Time
         \new Voice << \sopranoMusic \altoMusic >> 
     } % Staff
     ...
   >> % Piano Staff

Then, you can easily remove the Dynamic engraver, for example in the 
first case you can do:

 \new PianoStaff <<
     \new Staff { \clef treble \Key \Time
         << \new Voice \with {\remove Dynamic_engraver } \sopranoMusic \\ 
             \altoMusic >> 
     } % Staff
     ...
   >> % Piano Staff

assuming that it's the dynamics of the \altoMusic that you want to keep.
