hi all.. i just got a used sp 404..seesm to work flawlessly...but i have no clue how to interface it to my laptop (macbook 2008).. and i have no idea how to put music from the laptop onto the 404..

I'm sorry if i'm in the wrong section .. would be grateful if you could post this to the right one.. i've been reading all the posts regarding the settings and i also got the manual but i'm really stuck!! i'm very new to hardware (i've been using ableton for a while) and i m lost !!! many thanks to all of yo SP crowd..
