Hello everyone. I have a late 2010 iMac i3 upgraded to Mavericks 10.9.4. For the last two years I have been getting this error when Using Logic Pro 9, recently upgraded to Logic X: "Error While trying to Synchronize Audio and Midi" When ever I get this message, I get a bunch of popping and clicking noises and my COMPUTER RUNS SLOW, even when I try to look at youtube or listen to iTunes. It tells me my sample rate is recognized at 40973 and to check conflict between Logic and external device. Don't know how to do that. Some of the plugins I have are Trillian Bass, Kontakt 5, Focusrite mixers, Bass Station, Addictive Keys, etc. I also have a scarlett 2i2 audio interface, but it even does it when the interface isn't plugged in. I know every little about audio DRIVERS, and the Coreaudio whatchamajigger. I even tried to get help from the so called apple "genies" but to know avail. Does anyone have a "Simple yet effective solution to what I can do about this. Even if its not so simple, please be as plain as possible. I love music but I'm no tech head. Thanks.
