Thanks for the suggestion. Do you know on which LP9 install discs the exs24 (wav, aiff) content resides ? and Does Pacifist allow me to extract the files directly from these discs ? Well, anyway, I think it might be a good idea to move forward to OSX-Snow Leopard, and possibly use a new HD, since I would like to use a larger Main MacOS HD. I will backup important data, replace my current main OS-HD, with a new larger HD, and install OSX-SL. Then try to install LP9 on OSX-SL, and see how that goes as far as getting all the instrument contents installed on my system. Cheers.
