It'll play perfectly fine, then right before the spot where I duplicated time or created time, it'll pause for a split second.
I have a Mid 2012 15 Macbook Pro Retina and shouldn't be doing that. It's both with the built-in card and an external audio interface. It's been doing this since 8 so I dont know what it is!

Weird-thing: When I change the buffer samples up or down, it'll fix it but it will comeback randomly. It could fix it at one setting, then I restart the program, have the exact same settings then the dropout is there.
Anybody got any ideas, tips? What really sucks, is that it exports like that.
