Hi, As soon as I put Logic to sync in IAC mode with ProTools as master, I get an error message of "System Overload. The audio engine was not able to process all required date in time." I had this problem last week when I was running 10.5.8. I have since upgraded to SL 10.6.4. The problem persists. When I stop sending MTC to Logic from PT, the CPU calms down. I can't sync Logic and PT and have stem transfers to do each week. I'm stumped. Any ideas anyone? thanks!
