The pan is correct when I load the Sound Font in the AuSampler instrument in Mac, but in iOS I get only one channel. I've tried the sound font file provided by my client, as well as one I created from scratch.

However, I don't see any mention of that parameter, or any parameters in the (very sparse) documentation for AUSampler. Is my guess about a pan parameter correct? If so, how can I learn more about it? If not, any ideas about what's going wrong?
