RE: Synchronize music of different length

[Richard Sabey]

Hi Urs.

I tried to send a reply earlier. I don't know if I succeeded, but the method I suggested was not good enough anyway. Here's my second attempt at a solution to your problem:

\version "16.0"

firstVersion =

\relative e'' {

e2. e4 | g2. cis,4 |

}

secondVersion =

\scaleDurations #'(2 . 1)

\relative e'' {

e4~ e16[ fis] e[ fis]

\bar ""

g4. cis,8 |

}

\score

{

<<

\new Staff

\firstVersion

\new Staff

\secondVersion

>>

\layout

{

\context

{

\Score

\remove "Timing_translator"

\remove "Default_bar_line_engraver"

}

\context

{

\Staff

\consists "Timing_translator"

\consists "Default_bar_line_engraver"

}

}

}

Note that I have fixed a bug with the beaming in the second version.

All the business of removing two engravers from the Score context & putting them into the Staff context is needed because you have two music expressions running alongside each other, and the one has a bar line where the other one does not.

Now this is all very well because, musically speaking, all that was needed to make the two music expressions correspond was to treat each note in the second version as if it lasted twice as long as it actually does. If you had another example where the music expressions correspond in a different way from that, then you could try spacer rests ( s4 etc ).
