I'm trying to understand the pan property in the AEAudioPlayable protocol. I have created two AEPlaythroughChannel instances and then assign the pan property of one of them to -1.0 and the other gets 1.0. This works as expected one channel is only in the left channel and one is only in the right. The issue is how to change those values and have the output be correct. If I have a slider and change the pan value from -1.0 to 1.0 the channel does not go from the left to the right, it gets stuck in the middle. What am I missing?
