has anyone used this setup with garageband?

if so...how do i configure with garage band so that i can specifically:

1) play drums on a track.. not just the drums that are loaded on my mac.. but samples..

2) trigger samples

the editor librarian makes it easy to load preset scenes, but whenever i load them, i don't get anything changing in the output... I was assuming that the preset scenes were linked to audio, that would give me several different kits, but that is not working.. am I wrong?

is there any manual available that will take me through this process step by step?

all the reviews i read said "it can do this & it can do that".. now that i got it.. i cant do squat...

anyone?

thanks
peace
