For some reason it produces a exact copy of the input file:

$ lua -v
Lua 5.2.1  Copyright (C) 1994-2012 Lua.org, PUC-Rio
$ lua ~/panning.lua 2b_choer.midi zz.midi
2b_choer.midi   zz.midi
$ lsl 2b_choer.midi zz.midi

Oops, it looks like MIDI files produced by LilyPond 2.17 look a bit different to what 2.16 produced. This revised version of the script appears to work, and spat out the attached MIDI file...

Cheers,
