I've written a small script which can make this task a lot less tedious:


The script reads klick tempo maps (which are simple text files) and
rewrites the tempo markers in existing Ardour session files. If the
tempo map contains ramps it will add one marker per beat, just like you
You can still set the tempo of each beat individually if you need to,
but it should generate smooth ramps if you just say "change tempo from x
bpm to y bpm over this many bars".
