I guess because I like the playhead being tied to the actual current sample position, not a separate animation that is faking being connected to what's happening. With an animation, that's not really happening. If I change the sample rate / playback speed, then core animation has to be "faking" that. Where as if its position is just mapped to an X coordinate based on the math of the number of samples and current sample index, then you get all of that for free and it seems better to me. Patrick J.
