Hi
 
Files Move when changing project tempo
Is it there a way to turn that off?
 
I normally do more songs on a project when I record live
So, when we do one song we fix’s that and go on to the next song
So when I change the tempo for the new song all of the files from the previous song moves.
 
Normally I don’t use the metronome when I record live, the drummers have their own metronomes that they use to count them self in.
 
Or I do tempo map like when it’s a tempo change in a song

Maybe try locking the clips for the songs you don't want to be affected by the tempo change?
 
(Right click on the clip, "Clip Lock" -> "Lock Position".)

check your clip properties in the inspector and see whether you have set your "Time Base" to "Musical" or "Absolute"

it is common for a clip to move during tempo changes because the timeline changes, there for the clip needs to stretch and conform to the new alignment.

As Rob suggested, the reason is that audio clips have their start times referenced to Musical M:B:T time by default. This is appropriate if the audio is recorded to a click in the first place, and you want clips to retain their positions relative to the M:B:T timeline when changing tempo (with Autostretch enabled on audio clips as well). Changing clip Timebase to Absolute for all clips will allow the clip start times to retain there absolute timing.
 
But if you're not recording to SONAR's click, I don't know why you would care what the project tempo is...?
 
As for audio clip lengths changing when you change tempo, that's because the M:B:T timeline is the fixed visual reference in SONAR. Rather than having measure/beat lines get closer together at a higher tempo, for example, the Now time cursor travels faster. This means that an audio clip with a fixed absolute length will get longer, visually, to have the same absolute run time as the Now time cursor traverses it more quickly.
 
This is a little unintuitive if you're used to working in other contexts/programs where absolute time is the fixed visual reference. I'm not sure how many DAWs - if any - are built this way.
