Comment #1 on issue 3154 by address@hidden: option to specify the  
name of Midi files for each \score block
http://code.google.com/p/lilypond/issues/detail?id=3154

The fix for issue 2343 added the ability to change the overall output file  
name and output file suffix via properties in the \paper block. It should  
be possible to write a patch to generate midi file names and suffixes as in  
the following example:

% In source file mymusic.ly
\book {
    \paper {
       output-file="first-file"
     }
    \bookpart{
      %...some markup
      \score{
         .....music for ScoreOne
         \layout{}
         \midi{ output-file = "movement-one" }
      }
      %...more markup
      \score{
       %  .....music for ScoreTwo
         \layout{}
         \midi{ output-file = "movement-two" }
      }
    }
    % files generated:
    %   first-file.pdf
    %   movement-one.midi
    %   movement-two.midi
    %
 }

\book {
  % No output-file specified
    \bookpart{
      %...some markup
      \score{
         .....music for ScoreOne
         \layout{}
         \midi{ output-suffix = "movement-three" }
      }
      %...more markup
      \score{
       %  .....music for ScoreTwo
         \layout{}
         \midi{ output-suffix = "movement-four" }
      }
    }
    % files generated:
    %   mymusic.pdf
    %   mymusic-movement-three.midi
    %   mymusic-movement-four.midi
    %
 }

\book {
   \paper {
       output-file="third-file"
   }
   \bookpart {
      \score {
      % music for score
      \layout {}
      \midi  {}
      }
      \score {
      % music for score
      \layout {}
      \midi  {}
       }
      }
    }
    %   third-file.pdf     - Inherited from \book or \bookpart output-file  
property
    %   third-file-1.midi  - suffix defaulted from number of midi files  
generated in
    %                       current \book or \bookpart block
    %   third-file-2.midi  - suffix defaulted from number of midi files  
generated in
    %                       current \book or \bookpart block
    %
   \bookpart {
      \score {
      % music for score
      \layout {}
      \midi  {
                 output-suffix="fifth-movement"
        }
      }
      \score {
      % music for score
        \layout {}
        \midi  {
                 output-suffix="sixth-movement"
         }
       }
      }
    }
    %   third-file.pdf     - Inherited from \book or \bookpart output-file  
property
    %   third-file-fifth-movement.midi  - suffix specified in \midi block
    %   third-file-sixth-movement.midi  - suffix specified in \midi block
    %
}
