I would like to specify the name (or extensions) of the .midi files
exported by the \midi{} command. I have multiple \scores{} in one .ly
file producing one .pdf file and multiple .midi files.
I do something like that by setting up a \book block for each midi
output file. Each such block has a \score section and a \midi section
and starts off with a \bookOutputName (or just a \bookOutputSuffix)
declaration.
