for this project I’m testing this solution:
In particular I’m studying the MIDI part of the problem.
I created an Ardour project with a MIDI track and some MIDI notes. Time: 4/4; for the first bar, tempo 120/4; second bar, tempo starts at 120/4 and finishes at 60/4 (I simulated a big rallentando); third and last bar, tempo 60/4.
I selected the MIDI track, Region → Export… → Test.mid
$ fluidsynth -a alsa -m alsa_seq -l -i /usr/share/sounds/sf3/default-GM.sf3 Test.mid
fluidsynth plays the MIDI file at 120/4, from the beginning to the end.
Where is the problem? Is Ardour ignoring tempo mapping during the export, or is fluidsynth ignoring it?
I imported the MIDI file in Rosegarden; tempo is still 120/4 from the beginning to the end. So I think the problem is in Ardour export.
Is this a known bug?
