How to change tempo and not stretch audio clips?

I'm having trouble when I want to change tempo at a point in a project to record MIDI parts against, that the existing audio tracks stretch or bunch up and are then out of sync with where they should be. How to stop this? These are not Groove-Clips, just imported audio files. The only thing I've found possibly addressing this in the Help is about "enable audio stretching", but in Loop Construction View that button is off on all of the audio tracks, as it would seem it should be. So... ??????

Actually, in the situation I'm currently working with, I've got a video track (with it's accompanying audio track) and then the same audio track (minus backing music) that is synched with the video track. When I change the tempo, the video track (and it's audio track) stretches, but not the other audio track, so then it's all out of whack. Argh.

You've encountered one of my biggest complaints of Sonar. Audio clips are only associated with Bars:Beats:Ticks they can't be associated with a timecode location. Which makes it very difficult to work with video whenever you want to put in a tempo change--as you found out.

Please go to the Sonar feature request page: http://www.cakewalk.com/support/featurerequest.asp and let them know that you need some sort of feature to lock clips to timecode.

But if you enable looping then the clips do not stretch when you change tempo, which is what you want right? So, if you click on "Beats in Clip" in the loop editor and thus activate looping, you're good to go?

Ive encountered a similiar kind of problem. I havent yet tried those suggestions the above nice guys given , but ill tell my problem anyway.
I created a complete song out of Sonar and Reason, and added some singer`s vocals. Now after mixing the song and bringing it to a certain shape,, i realise the song was recorded at a much faster tempo than i originally intended to, so i reduce tempo, and WHOA!!!! the Vocals are seriously out of sync, i laughed at some moments, but was disappointed that i couldnt find a setting that would allow me to stretch the vocal track as perfectly as it was in sync when it was recorded. The Reason tracks and the Vsti i recorded were in perfect sync ironically though.
