Director I am familiar with :D Thank you for the advice!
I just put the code in my app to test it. I made it so that when you toggle something on the menu (with menuscene) then it clicks. It does click, but the first time I press the toggle it also pauses/freezes for about a second first. I assume I need to preload/buffer the sounds beforehand. Using preloadEffect, or something *looks at the SimpleAudioEngine.m* aha! preloadEffect is what I'm looking for.
EDITED: ignore the above, the preload works great.
I don't see anything in there for volume. Can these be changed on the fly?
