Creating an Ardour session with dozens or even hundreds of tempo or meter
changes is tedious, so I wrote a script to do that for me. See
http://das.nasophon.de/klick/, the script klick2ardour.py is at the bottom
of the page.
Basically it reads a tempo map (a simple text file) that describes the
structure of the song, and writes that to an Ardour session. The tempo map
format is described at http://das.nasophon.de/klick/manual.html#tempomap.
klick even supports "true" tempo ramps (no steps). Since Ardour doesn't, the
script generates one tempo change per beat. I hope that's close enough :)
