cpu overloads tip

hi guys i found this on another forum and i thought it may be a good workaround for people suffering with cpu overloads. I have a possible fix for the common cpu overload problem that so many Logic users are experiencing! I am using Logic 8 on my Mac Pro 2.66 quad machine. Even with a simple project, about 95 percent of the workload was being handled by one core. It was constantly spiking while the other three were hardly showing any activity at all! This spiking wasnâ€™t simply a visual thing either. It was causing glitches in the sound and I was getting â€œsystem overloadâ€ messages quite often. I tried increasing my buffer size which helped the one core not to spike, but even this adjustment didnâ€™t do anything to help even out the workload within the processor. HERE IS HOW I DISCOVERED THE FIX!!! I was experiencing some hiss from one or more inputs during a project. In an effort to eliminate the background noise, I set the input of EVERY AUDIO TRACK to â€œNO INPUT.â€ Of course, the hiss disappeared, but to my surprise, the one meter that seemed to be carrying the entire load went down to a normal level and my workload was basically evenly distributed among the 4 cores of my processor!!!! I tried this on a very complex project with the same results. I opened a project with 70 tracks, both audio and midi, with automation and effects. The one meter of the cpu was constantly spiking. I set all audio track inputs to â€œNO INPUTâ€ and the problem was fixed! All 70 tracks running smoothly with all four cpu meters carrying an equal load and each only peaking at about 50 percent!!!! Now, I simply assign inputs to my tracks while tracking, and when Iâ€™m finished recording those tracks, I reset the tracks to â€œno input.â€ And by not allowing a bunch of inputs to accumulate within the project, I have no more problems whatsoever with cpu spiking!!!!! Give it a try, it solved the problem for me and I hope it works for you!!! NO MORE SYSTEM OVERLOADS OR GLITCHES!!!
