Apparently Logic Studio has some new presets. However, Apple also removed many presets that were in Logic Pro 7. I spent the morning moving presets around and installing new (old) ones. If you have any presets saved, you will most likely have to move them to the new installation. You can find them in MAC OSX/Library/Application Support/Previous Logic Settings/ The Logic Studio preset location is MAC OSX/Library/Application Support/Logic/
There is also a section of the Logic Pro Help Forum that is for uploads of presets, and channel strips. http://logicprohelp.com/index.php You can find all the old presets and others there.
