How to export tempo changes from on project to a new one

[distorson]

Hey,
I made a track in ableton live with some tempo changes. Now I want to use some of the audio files in a new project and I would like to copy the tempo changes from the first project into the new one. Is there any workaround to realize that? I didn't found anything helpfull in the manual or the internet.
Thanks and regards.

Here's one trick:

So you have tempo changes automations on your master track.
Create a midi track with an Operator playing a simple click sound or a Simpler playing similar sound every 1/4 note. Make it as long as your live set.
Now, freeze and flatten this track. And save the clip somewhere. Your tempo changes are now stored into this clip by the warp markers.
Open a new set and drag this clip onto an audio track.
In its clip properties, under the "sample" panel there's a "slave" button (under the "warp" button. Click it and it will turn into "master".
Now, if you look at your Master track's tempo automation you should see the automations from your previous set.
Right-click on the automation or on the BPM and select "unslave tempo automation". Done.
