Yeah, might as well wait! I just realized why I was getting hung on the [isa _soundIsAU:] call (forgot to include the implementation .m file on the build) anyway. The the seg fault can be looked at later.
I want to start slowly and actually plan this time around. Last time I just pulled up an editor and started typing, look how well that turned out! I'm going to try to have a proposal sometime soon, then we can go poke holes in it.
