New 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

Reported by Javier:
http://lists.gnu.org/archive/html/bug-lilypond/2013-02/msg00016.html

Currently LilyPond allows to set the name of Midi files only for book  
blocks, using boookOutputSuffix or bookOutputName.
Javier is asking to add a similar feature for the \score block.

Discussed on lilypond-user:
http://lists.gnu.org/archive/html/lilypond-user/2013-02/msg00028.html

Here's the feature request:

Requesting adding the ability to state a filename for midi output from  
within
score's midi block (or other score-specific block).

\book{
  \bookpart{
      ...some markup
      \score{
         .....music for ScoreOne
         \layout{}
         \midi{ \set midifilename = "chap1-piece-one" }
      }
      ...more markup
      \score{
         .....music for ScoreTwo
         \layout{}
         \midi{ \set midifilename = "chap1-piece-two" }
      }
   }
  \bookpart{
      ...more markup
      \score{
         .....music for ScoreThree
         \layout{}
         \midi{ \set midifilename = "chap2-piece-one" }
      }
      ...more markup
      \score{
         .....music for ScoreTwo
         \layout{}
         \midi{ \set midifilename = "chap2-piece-two" }
      }
   }
}

Allows one to build a single book.ly file (collection of scores) that  
produces
a single "book.pdf" output, as well as individual midi files with user-
selected names significant to their content/context (i.e. chapter number,
composer, opus, etc.).
