A nice thing with Lua would/could be that many entries actually could
be code. For example one could define harmonic voices in the config
file as functions like: 

  function major7(n) return {n, n + 4, n + 7, n + 10} end

and use this with the instruments: 

  sax(major7(60))

or 

  c = major7(60)
  sax.play(c)
  trumpet.play(c)
  c = minor7(62)
  sax.play(c)
  ...

I don't know if it makes sense to write a general purpose file loader
around this, but I plan to do some examples of this approach.

Ciao
