I have been using logic 7.1 with no problems until today. I start a song that was previously recorded...and instead of any sound I get clicks and pops and error messages telling me that there is an audio midi sync error. The only thing I can think of is that I did a software update for my mac last night. Before that there was no problem. Does anyone have any suggestions I have a deadline to deal with...and I am freaking out!!! Any help would be greatly appreciated Peter

Make sure your sample rates are set the same for the Logic and any other digital gear u have.
