Yes the motu 828mk2 is running on its own bus and i'm using 3 internal drives no external firewires with 3gbs of ram. i don't think adding more ram should resolve the issue because logic can't reach more than 4gbs of ram as far as i know. it's interesting to see other people having the same problem. here's the weirdest thing i found out though. not after every crash but after some crashes, my motu 828 goes crazy. the small green display starts showing gibberish characters. i reset to factory defaults and that's the only way to fix it. Is logic/mac pro/coreaudio killing my sound card? is this possible? I'm usually good at finding the origin of problems in my computers, but i'm really puzzled by all this. It looks like there's more than one source of problem. And yes logic crashes if i want to add an audio file too. But all of this stuff won't happen in a fresh blank session. The problems start with bigger sessions. The whole thing might be because of running multiple 3rd party soft synths too but i simply would be out of work if i quit using stylus rmx, kontakt and all the good stuff NI has to offer. I had problems with RMX in the past so i'm usually bouncing that right away so it won't create problems. Thanks for all the input. Kaplan
