I'm attempting to use an audio action with an AUPitch filter to transition from one pitch value to another. However instead of gradually changing over time, the entire clip will play using the pitch value based on where the scrubber is.

For example, if I start the clip from the beginning, it will be at the starting pitch I set (let's say it's 0). If I pause and then resume at the halfway mark, the remainder of the clip will playback using the pitch value halfway between my start and end values.

So if my end value is say, 100, pausing and resuming from that halfway point makes the rest of the clip play at 50. Continuously pausing and resuming shows that the pitch is indeed changing throughout the audio action, it just doesn't play it back properly (this also goes for exporting).

This seems to be specific to using AU filters, as changing values for volume and such work as expected. The inspector also shows this during the audio action playback:

I'm also seeing "No Properties" when I'm directly on the action. There seems to be no transition during playback from before to after the action. The pitch abruptly change post action.
