Conflicting audio event will be bounced

I have a project with midi and audio. All the parts sound in time and most of audio was from recording the midi tracks, which accurate with click track. It is almost all 139bpm, then changes to 140bpm the rest of the way. I wanted to do set tempo from definition, so I could slow speed but it says it will bounce 134 conflicting audio events. So now I’am hesitant, not knowing what that is going to do.

That tells you that there are 134 instances where 2 or more Audio Events in your Project Window are based on the same underlying Audio file. If you look in the Pool it even lists how many times each file is being used. This can potentially cause problems if one Audio Event wants to change an Audio File in one way and a different Audio Event wants to change it in another way. To avoid this Cubase offers to Bounce the Events so each one has their own unique Audio File to modify. For most use cases you’d want to do this. Your original Audio Files will be left untouched.

OK, I see in the pool one even it says is used 110 times, but it is all on the same track, which is broken into many sections when I fitted a tabla part recorded at a different tempo to this version of the same song. Maybe I duplicated the parts.
thanks.

Jargon alert - actually they are Audio Events & not Parts. An Audio Part is a container that can hold multiple Audio Events.

Even if you just put the whole file on the Timeline and cut it up a bunch they will show up as different Audio Events - duplicating isn’t the only way to create them.
