Sync Tempo with Audio Tracks


New member
I'm using Logic Pro X. I have some songs that were live performances multi tracked with an XR18 as we were performing. Im trying without success to sync the tempo up with the audio (I understand it won't be perfect) to do some rhythmic delays. Whenever I changed the Tempo it just moves the audio with it. Is there a way I can make them operate independent of each other so I can try and adjust the tempo to a point that it fits the audio?

Usually I just manually set the delay time rather than trying to sync it to an external tempo or set the tempo on a song that wasn't recorded to a click track. I hope that makes sense in the context of Logic Pro.
