Our set up is a Motu 828 MK II sound card with an external firewire hard drive plugged into it and the MOTU is plugged into the computer through an other firewire cable. Just today after getting set we turned on our computer and started up logic express 7 and tried playing a song. With in a few seconds we recieved an error that said "Error while trying to syncronize Audio and Midi", and some strange high pitch noises started coming out of our moniters, but the channal strips showed that the song was playing normally, besides for this Error. We have recieved this once before and after restarting the computer the problem went away. We have restarted 4 times already and shut of our MOTU with the computer still on after dragging the hard drive to the trash about 5 times. I tried looking in the some of the preferences and just can't find out what is going on. Can someone please help us out soon. We are recording a CD and have dont everything except for Vocals, and we were planning to finish those with in the next couple days. This CD has already been set back by months before and we can't afford an other set back. Please help us right away. Thank you. Ben
