Re: Suppressing engraving of string numbers on all voices simultaneously

[Dave Trombley]

This is perfect, thanks!   It's all working. 

Arguably this is not a super-common use case, but it is illustrative of how these features work / are associated.  Perhaps it should be added to the snippets?

That will still reserve space for the string number.

An override for Voice will work for the current Voice.

Again, transparency is the wrong solution since the spacing will still
be affected.  You can just use

\omit Staff.StringNumber

to have string numbers omitted for the entire Staff.  Of course you can
also do so in the whole score by specifying

\layout {
  \context {
    \Staff
    \omit StringNumber
  }
}

\once \undo \omit StringNumber

might work for a single string number.
