Audio Overload Message

Hi Guys,

I get an Audio Overload message while working on Logic 9 , surprisingly I don't see that Logic uses the second core (checked the same clicking on core performance option) .

I don't use added effects as such but yeah mostly work on AU instruments and EXS 24 sampler ; have a white macbook with basic config - 2GB ram , 55 GB (250GB) free with 2GB DDR 3 Ram.

I'm looking forward to upgrading my RAM to 4GB next week , wondering if that solves the problem.

Cheers,

Gaggy
