Re: Struggling with Midi and long repeats

[Knute Snortum]

Well, that was the output you gave me.  Below I've cleaned up the example with some notes that make more sense to illustrate the use of \unfoldRepeats with alternate endings.  You can change it or apply it any way you want.

(In the future, please post examples that compile.)

%%%

\version "2.22.2"

upper = \relative c' {
  \voiceOne
  \tempo 4 = 90

  \repeat volta 2 { b b b b }

  \alternative {
    { a a a a  }
    { g g g g  \mark \markup { \italic "Fine"   } \bar "||" }
  }

  c d e f g a b c \mark \markup { \italic "D.C. al Fine" }
}

lower = \relative c {
  \key g \major
  \voiceTwo

  \repeat volta 2 { b b b b }

  \alternative {
    { a a a a  }
    { g g g g }
  }

  c d e f g a b c
}

\score {
  <<
    \new StaffGroup = "tab with traditional" <<
      \new Staff = "guitar traditional" <<
        \clef "treble_8"
        \context Voice = "upper" \upper
        \context Voice = "lower" \lower
      >>
      \new TabStaff = "guitar tab" <<
        \context TabVoice = "upper" \upper
        \context TabVoice = "lower" \lower
      >>
    >>
  >>
 
  %%% Below, tells LilyPond to only create PDF
  \layout {}

}

%%% Below, create a MIDI-only score with repeats unfolded
\score {
  \unfoldRepeats {
    \new Staff <<
      \new Voice \upper
      \new Voice \lower
    >>
  }
  \midi {}
}

%%%

I'm sorry you're having troubles with LilyPond.  If you tell me what you don't get I (or someone) can help with that.

As a starting point, here's the LilyPond source code you posted, corrected so it will compile, and with the MIDI honoring the repeats:

%------

\version "2.22.2"


\header {
  title = “%%%%"
  composer = "Omer Katzir"
  tagline = "http://omerkatzir.net"
}



upper = \relative c' {
  \time 3/4
  \key g\major
  \voiceOne
  \tempo 4 = 90


b b b b


}

lower = \relative c {
  \key g \major
  \voiceTwo

  \repeat volta 2 { b b b b b    }


  \alternative {
    { a a a a  }
    { a a a a  \mark \markup { \italic "Fine"   } \bar "||"
  }




  }

c d e f g a b c \mark \markup { \italic "D.C. al Fine" }


}

\score {
  <<
    \new StaffGroup = "tab with traditional" <<
      \new Staff = "guitar traditional" <<
        \clef "treble_8"
        \context Voice = "upper" \upper
        \context Voice = "lower" \lower
      >>
      \new TabStaff = "guitar tab" <<
        \context TabVoice = "upper" \upper
        \context TabVoice = "lower" \lower
      >>
    >>
  >>
 
  %%% Below, tells LilyPond to only create PDF
  \layout {}

}

%%% Below, create a MIDI-only score with repeats unfolded
\score {
  \unfoldRepeats {
    \new Staff <<
      \new Voice \upper
      \new Voice \lower
    >>
  }
  \midi {}
}

Well, I’ll be ashamed but honest. I didn’t understand anything from it. Maybe lilypond is just not for me for more complicated pieces.

I have this music, but when I try to make midi out of it, it doesn’t do the repeats. Does anyone have any suggestions on how to do it?
