I'm trying to get Live to set the session tempo to a .wav recording of a live drummer. I've trimmed part of the recording into a 2-bar loop and am dragging and dropping the sample into live but it utterly refuses to set the tempo correctly. I've done it a million times before using whole (MP3) tracks and it always calculates the tempo correctly from the first track you import/drag into the track view.
Anyone know why it's refusing to cooperate before I go mental? :S
