If the Devnull context is supposed to discard all musical info given to
it, it doesn't.
Assume myMusic = \notes {...} has polyphony on a single staff in it. Naturally, calling \myMusic works fine. BUT, doing this:
try this
****************
\header { texidoc = "A second staff can be aligned to a fragment (say, a cadenza), using a Scheme function: the function creates a skip of the same length as the cadenza. "
}
\version "2.1.37"
cadenza = \notes \relative c' { c4 d8 << { e f g } \\ { d4. } >> g4 f2 g4 g }
#(define (skip-of-length mus) "Create a skip of exactle the same length as MUS." (let* ((skip (make-music 'SkipEvent 'duration (ly:make-duration 0 0))))
(make-event-chord (list (ly:music-compress skip (ly:music-length mus))))
))
#(define (mmrest-of-length mus) "Create a mmrest of exactly the same length as MUS."
(let* ((skip (make-multi-measure-rest (ly:make-duration 0 0) '() ))) (ly:music-compress skip (ly:music-length mus)) skip ))
\score { \notes \relative c' \new GrandStaff << \new Staff { \cadenza c4 \bar "|." } \new Staff { #(ly:export (mmrest-of-length cadenza)) c4 \bar "|." }
\paper {} }
