Where can I find presets to download?

Hi all,

I have just installed garageband and have been fiddling around with it. One thing I wondered was whether there are any resources online that you can download preset effects settings from. For example when wanting to mimic and artist or song, you download the preset for this and it automatically sets up garageband to those settings.

I have had a google, but it seems there is nothing? Does Apple even allow this?

Thanks

Tom
