MIDI export: \partial measure and volta repeats

[Federico Bruni]

Hi,

I'm trying to export a lilypond score to MIDI (then I want to import 
it in TuxGuitar).
I have 2 problems:


1. the score starts with a partial measure, but the MIDI can't 
understand that...so when I import it in TuxGuitar, the notes are not 
placed correctly in the bars.
There's any cool workaround?

I know TuxGuitar does not support partial measure.. Maybe I should 
write a score tailored for the midi output (beside the one for the PDF 
output) and substitute \partial with some rests.



2. the repeats and alternatives are not displayed correctly. I've read 
about this workaround:
http://lilypond.org/doc/v2.13/Documentation/user/lilypond/Repeats-in-MIDI#Repeats-in-MIDI

But the problem is: I have a two voice score and the repeats are in 
the voices.
Again, I can't see any solution but writing a tailored score for the 
MIDI output (that is, creating a copy of the voices and replacing 
volta repeats with unfold repeats).

Or there is a smarter way to get the same result?

Thanks for your help!

Federico

To be very clear, I'm thinking about something like this:

% pdf output music
upper= { music with \partial and volta repeats...}
lower= { music with \partial and volta repeats...}

\score {
 <<
     \new Staff = "guitar" <<
          \context Voice = "upper guitar" { \clef "G_8" \voiceOne 
\upper }
          \context Voice = "lower guitar" { \clef "G_8" \voiceTwo 
\lower } >>
     \new TabStaff = "tab" <<
       \context TabVoice = "upper tab" { \clef "moderntab" \voiceOne 
\upper }
       \context TabVoice = "lower tab" { \clef "moderntab" \voiceTwo 
\lower } >>
 >>

        \layout {
        }
}


% midi output music
uppermidi= { music without \partial and with unfold repeats... }
lowermidi= { music without \partial and with unfold repeats... }

\score {
 <<
     \new Staff = "guitar" <<
          \context Voice = "upper guitar" { \clef "G_8" \voiceOne 
\uppermidi }
          \context Voice = "lower guitar" { \clef "G_8" \voiceTwo 
\lowermidi } >>
     \new TabStaff = "tab" <<
       \context TabVoice = "upper tab" { \clef "moderntab" \voiceOne 
\uppermidi }
       \context TabVoice = "lower tab" { \clef "moderntab" \voiceTwo 
\lowermidi } >>
 >>

        \midi {
        }
}
