Is there a way to make the audio files in a project change the speed along with the tempo without changing the pitch. IN Samplitude, it would prompt a message asking if I want to change the audio data. In Cakewalk, it simply changes and the original audio files remain at the original tempo.

Before changing the tempo select all of the audio tracks. Enable Audio Snap with the option for Follow project tempo (auto-stretch option). I prefer Elastique Pro algorithm for Online (realtime) playback and Radius mix for Offline processing. Change the tempo(s) to your liking. Once you're happy with the tempos Right click and Bounce to clip to Offline process tracks with the good algorithm.

Thanks. Will try this when I get home and report back

You know, I never tried that. That works well. Thanks.
