Resolution of the ponering on Chordmode

[Peter Gentry]

David provided the best solution. See file below

\version "2.19.25"
\include "predefined-ukulele-fretboards.ly"
\storePredefinedDiagram #default-fret-table \chordmode {c:dim7}
                        #ukulele-tuning 
                       "5-3;3-2;2-1;o;"

myChordsTransposed = \chordmode {
  e1:7 |
  s1 |
  a2 g |
  c2:dim7 a:7 |
  d1 |
  s1 |
  s2 s4 g |
}
\score {
<<
\new ChordNames {
    \myChordsTransposed
}
 \new FretBoards {
    \set Staff.stringTunings = #ukulele-tuning
    \set ChordNames.midiInstrument = "acoustic guitar (nylon)"
    \myChordsTransposed
  }

  \relative c'' 
  \new Staff {
    \set Staff.midiInstrument = "acoustic guitar (nylon)"

\transpose c b {
      \key ees\major
      r1 |
      r1 |
      r2 r2 |
      r2 r2 |
      g4^\markup{\musicglyph #"scripts.segno"} g8. f16 ees8. bes16 ees8. f16 |
      g4 g ees2 |
      g4 g bes aes8. aes16 |
      g4 f f2 |
   }
}
>>
\layout {}
\midi {}

I would never have thought of adding the midiInstrument to the FretBoards.
