I just got my new Mac Pro 2.66 / 2 gig Ram and MOTU traveler. I'm running my new sessions at 192k / 24 bit. Currently running 25 stereo audio tracks and 5 Instruments Ultra beat, Sculpture. I keep getting A Core Audio error message that says "System Overload, the audio engine was not able to process all required data in time. I've adjusted the I / O buffer size settings and still no luck. Am I missing something? I expected to get better performance from this set up. thanks Aaron
