Garage Band

Does anyone know of a good way to learn Garage Band. Is there is site better that the Mac tutorials to help a person out learning this thing??
I really like it but have lots of questions.

Myself and a friend use it( or at least some of it ). Most/ all of the knowledge we gained was through trial and error. It takes time.

How did you overcome the !/2 second lag time, or was it fixed in a newer version?

I haven’t run into any lag.  I use it all the time to make ringtones :smile:  and to edit audio for a podcast.

Ringtones??? oooh, can it be used with PC?
