Okay - now I understand better.
Maybe there’s a way of doing that by using track lanes?
However you’d need to prepare the audio tracks in question
- musical mode off in for the source audio file in the pool window
- musical mode on for the selected track, if you want the starting points of each audio event to be fixed to the same bar after changing tempo.
- Move each successive audio event to it’s own lane
- Select all of the resulting events, and lengthen them all by a generous amount
- Hide the lanes to reduce the clutter in the project window.
The resulting audio track (before hiding the lanes) ends up looking something like this:
Now you can change the tempo, and the each audio event will start at the same bar position, but will always play to the beginning of the next one.
p.s. The step to create lanes may not be strictly necessary, but it guarantees which audio event is “in front” and therefore being played.
