Greetings Luggers, I wonder if anyone can help. I just upgraded to LAG 4.0. At the same time I stuck the Yamaha SW1000 XG card in my B&W Mac G3. Nice interface, lovely effects, beautiful plumage etc etc but the trouble is the damn system keeps crashing. Could it be the SW1000? Could it be the Logic 4.0 upgrade? Could it the bloody Roland MPU64 midi interface that this dumb configuration requires? Are there some known bugs? I realise this has probably been covered months ago (I've been asleep for a while) but if anyone could give me any ideas as to how to track down this problem, I'd be extremely grateful. Regards, Michael Kretzmer PS Oh yes, the XG editor off the Sw1000 also crashes frequently...
