Hi,

i have a MBP retina 15" 2,3 Ghz connected to FF UC. All drivers are updated. Under Logic 9 32bit mode i can record live with 64 samples safe. 32 samples are not possible. i am wondering because i just use one track without effects. It comes even worse under the 64 bit mode just 256 samples are safe. when i set it to 32 samples i also have cpu spikes every few seconds even when nothing is loaded and nothing happens in logic. Does anyone have experience with this setting? i tried a lot of things and have no clue. Thanks for any help!
