OK, let's write it shorter (just as example, it's only a excerpt of my whole 
code) :

\score 
{
  <<
    \chords
    {
      \transposition bes
      gis,1:m7.5- cis:7
    }
    \new Staff \relative g'
    {
      \transposition bes
      b8 d fis2~ fis8 gis | f2 cis' |
    }
  >>
}

This doesn't work : in midi file melody is OK (I hear F# for gis written in 
code) but chords doesn't (I hear B chord for b written in code. I should 
hear A chord). 

To put it simply, I wrote the sheet for a Tenor Sax, so the score and the 
accompagnying chords are written for a Bb horn. But I want the midi file to 
be generated correctly, so lilypond should transpose the whole a whole-step 
lower (playing C on the tenor sax and a Bb on piano sound the same).

What am I doing wrong ?
