Hi.
I'd like a "Voice" to be totally invisible (i.e. taking up no space)
while
retaining midi output.
Then don't include it in the \score block with a \layout. You can
have
multiple \score blocks in a file.
\score {
\new Staff {\bagpipeMusic}
\layout {}
}
\score {
<<
\bagpipeMusic
\droneMusic
>>
\midi {}
}
Unfortunately, that doesn't fit well with my current "templates": I
use one
file for each instrument, then another file for the full layout
(that refers
to the "Staff" variables defined in those other files) and then
still others
that contain the "\score"... Well, in short, I'd rather keep the
reference
to "\drone" in the bagpipe file, if possible.
Hence seeking the eventual "\set" or "\override" that could get the
result.
I assumed that something akin to "[...] #'stencil = ##f" would have
been nice
but, if that doesn't exist...
