Logic Pro 8 Making your own sounds

Can someone recommend me a good book or website that teaches you how to make sounds in Logic 8? Or how to change sounds etc.

I'm thinking about not using ReWire for Reason but one aspect of reason I like is being able to make your own sounds. I know I've barely scratched the surface with Logic 8 so I was wondering how to do stuff like that. Thanks!!
There are so many Instruments in Logic, it's to even say where to start! :eeek:

MacProVideo.com have really good tutorials - check them out.

You can also do searches on youtube for each instrument in Logic eg

Also fool around with EVD6 - it is better than one thinks at first listen.
