When it did crash I heard a loud buzzing sound and then realized it was coming from the first 2 ESB channels. I unassigned then reassigned the channels and the buzzing stopped. I thought that I was lucky in not having had any ESB problems like others but guess I'm not so lucky afterall. I guess the ESB is still unstable, the same thing happened in both Logic 7 & 6 . The only wild card is that I was playing with Spectrasonics new Stylus RMX, maybe it's so new there are some problems with that? Ed Alton
