Re: How to force a superfluous CombineTextScript to be printed?

[Ian Hulin]

Hi Dominic,
Have you tried using \partcombineApart and \partcombineAutomatic?  (See
code below).  See also Notation Reference 1.5.2 - Automatic Part Combining
http://lilypond.org/doc/v2.17/Documentation/notation/multiple-voices

There are also \partcombineUP and \partcombineDOWN flavours of
\partcombine (same syntax as \partcombine) which force both the parts to
use the specified stem direction when combined.

The code below is still a work-round to get the "a2" to print, but you
might want to use this as a template.

The \partcombine call is pretty horrible but this way you get the
\partcombine<mumble> directives applied to both parts without having to
add them individually to each the music for each instrument.

At the moment you get dynamics above and below the combined stave, but
you could control this with tags on the flutedyn variable so it only
gets used when you're print out the flute part.

Hope this gives you some ideas to work around the restriction without
too much pain (and typing) in your big score.

HTH, Cheers,

Ian
