Hi i have sonar platinum and want to know when i groove clip a audio file why does the pitch change? it matches tempo great except is sounds high pitched from the original audio file. So does anyone know how to tempo match audio and keep the pitch sames? Thats what i love about abelton auto tempo match sonar platinum must have too....cheers

You should be able to stretch a groove clip without changing the pitch. But your post says you are groove clipping an audio file. What exactly are you doing i. e. detailed steps to create the issue? 

It seems ok today for some reason and ive notice its only some samples that do it they just dont like being grooved clipped

Some groove clips are configured as pitched, and the native pitch is part of the clip's groove configuration. Then they follow the current key signature of the project, or some interval you can modify for the clip. Other groove clips are configured as not pitched, so they don't get transposed. You can modify the pitch or remove the pitch by operating on the clip in the groove editing window, usually accessed by double-clicking the clip.
 
A slightly different approach would be to turn off grooving and use the stretch tool instead, which can change the clip length with no change in pitch.

thanks for the advice bvideo! so how do i use the stretch tool sound like that could be a good way off do things...cheers  

Place the clip so it begins where you want it. Then place your cursor just before the end of the clip while holding ctrl + shift. When you see a funny looking cursor that looks like it should refer to clip stretching (!?) click and drag the end of the clip to stretch it or shrink it so it fits where you want it. It helps quite a bit if you start by setting the snap resolution to a unit that will help you land where you want it.

Thanks mate ive got it working correctly and what a difference cheers
