I have two audio files of full length songs that I want to work with. Neither is a loop. I want to import the first track, beat-detect it (which comes out to 145), and set the project tempo to match that track. When I import the second track, I want Logic to make that track match the tempo of the first track (or project...both are the same). Every time I try to detect tempo it says "no tempo could be found". If I use the marquee tool to select a small region of the file in order to beat detect that region, it says that there's no audio selected...so that doesn't work. I don't know why it will detect the tempo fine on one, but not on the other. I've tried everything I know how to do. The ultimate goal is to use a part of track 1 as an intro at 145bpm, which then goes directly into another track that is sped up to 145bpm, but with the pitch exactly the same as the original track. (Both tracks are natively in the key of F) Make sense? I'm using Logic 9.
