Re: Suggestion: new property "filename" for MIDI output

[Ian Hulin]

Hi Manuel,
You'll need to arrange your project so you can generate output for your 
overall main score and for individual players' parts, using variables 
and \include files.

You'll need to generate the  midi files from the compilations when you 
generate the individual parts, so these files will look something like this:

% DjembeOne.ly
% Part for Djembe 1 player
\version "2.12.1"
\include "DjembeOneMusic.ily"
%%
%% DO NOT PUT ACCENTED CHARACTERS IN THE STRING FOR
%% output-suffix or your file-names (trackers 714 and 832)
%% OR LILYPOND WILL CRASH WHEN IT GENERATES THE PDF FILES
%%
#(define output-suffix "Rhythm")
\book {
        \midi{}
        \layout{}
        \score {
         \DjembeOneRhythm % You'll have defined this in
                          % DjembeOneMusic.ily
        }
}
#(define output-suffix "Echauffement")
\book {
        \midi{}
        \layout{}
        \score {
         \DjembeOneEchauffement % You'll have defined this in
                                % DjembeOneMusic.ily
        }
}

This should produce midi files named DjembeOne-Rhythm-1.mid and 
DjembeOne-Echauffement-1.mid. You'll also get separate pdfs 
DjembeOne-Rhythm-1.pdf and DjembeOne-Echauffement-1.pdf.

There are patches waiting to be reviewed in the development system to 
sort out the accented characters issue and the numbering in the output 
filenames.

I'm looking at developing a property for the midi code to use in the 
development version but I'm on a steep learning curve so it may take a 
while.

Cheers,
Ian Hulin
