Change the tempo of audio tracks

[Grace de Richebourg]

Hello boys & girls i finished some songs and i would like to experiment different tempo: (bpm)
My songs is 100% audio composed.
So i switched every tracks on timestretch in the inspector then i changed the bpm in the little low central banner of the window and.... nothing happen ?
Thanks for you enlightment.

To have a track change tempo with the song's tempo it must have a tempo in the inspector, further down in the window. If the track's tempo box says "not set" then "timestretch" will not work. The easiest way to make it work is to enter for each "not set" track the initial value of the song's tempo, before you start fiddling with it. The best way to make it work is to enter the actual exact tempo for each track which, depending on the track's content, can be a fixed tempo value or a tempo map (for a variable tempo track). Deep subject.

Thanks a lot for your answer !
But God im unable to find that box saying "not set" ??
Where is it please ?

First select a track event, then open the Track Inspector (if not open already). Slowly move your mouse cursor down across the Inspector window and note that there are handles/dividers you can move upwards to reveal more boxes/options further down.

An alternative (if I remember correctly) is to right-click a track event to open a window with event properties. That should have a Tempo box too.

Ok cool i see it with the right click but not in the inspector so strange
Thanks a lot will try if it works now.

It is in the inspector, but below the fader portion. But right click is fine as well

Ok a feedback for future users, i could not find the "not set" box simply because i prolly deleted it from the customisation menu in the inspector window...
So thanks a lot guys it works fine !!!! (even if it looks that some audio region could be affected by overlap... if someone know how to avoid that do not hesitate to tell me please)

If you "bounce" a track, it will take the current tempo. There are many reasons not to bounce, but it's just some info. If you have audio tracks that are "not set" and possibly split or otherwise edited. If you select everything on the track and bounce it in place, then it will combine everything and set the tempo to whatever the current song tempo is.

Then you can change the tempo, etc. without any overlap problems.

Not sure i understand, are you saying that when changing tempo the best way is to bounce all the track from beginning to end to avoid my overlap problems ? If yes im all agree but i think it adds extra work lol so its a pity it does not overlap without bouncing.

It avoids the overlap and also automatically assigns the tempo, so you wouldn't have to right-click and set the tempo. Every time you bounce a track it auto assigns the current tempo of the song. If it's a tempo mapped song, it will set it to mapped, if not it will set it to the tempo you have set for the song.

So in your case. Instead of doing all the work to go into each track and assign the tempo, you could have selected all the tracks and events and hit "ctrl-b", ("cmd-b" on a mac) and it would have combined all the overlapping events and assigned the current song tempo to every track. One command for the entire song to do everything. Then you could set the tracks to timestretch and change the tempo however you wanted.

Ok gabo thats very nice thank you !

(ideally i would like to avoid bouncing like this because you lose every region, its a bit confusing and scary i think but yes, when the song is finished thats a clear option of course but when the song is not finished and you want to make some test on the fly this is not really adapted but this is a small detail so i will not worry too much about this.)

Totally understand that decision, just wanted you to be aware of how things work in S1.
