Re: x-offset in <<\\>> environment?

[Mats Bengtsson]

Please always try to turn your example .ly code into a full
example that others can run and try directly. As long as you
keep the attachments small, you can also include a PNG or whatever
of the output in your email.

There's one detail about the << \\ >> construct that's only shown in the
examples but not explained in the text (as far as I can see), namely that
the first and the third voices will have stems pointing upwards and the
second and fourth will have stems pointing downwards. Also, in the
third and fourth voices, the notes will be moved to the side to avoid
collisions. Therefore, the easiest solution for your is to add an empty
second voice:
\version "2.8.0"
\new Staff  {
\time 3/4
<< {s4. fis8-. r r | d-. r r
   ais-. r r | fis-. r r d-. r r |
   ais-. r r fis-.
   r r } \\ {} \\ { \stemUp d2.( | d)( |  d)(  |  d) } >>
}

or to explicitly say \voiceThree for your second voice:
\new Staff  {
\time 3/4
<< {s4. fis8-. r r | d-. r r
   ais-. r r | fis-. r r d-. r r |
   ais-. r r fis-.
   r r } \\ { \voiceThree \stemUp d2.( | d)( |  d)(  |  d) } >>
}
