Alright, I just got my Motu ultralite mk3 and I am not the most computer savvy person in the world. I'm usually not that bad with stuff like this but i've been having some problems. I think i'm following the instructions okay, but i am getting no sound through the interface. The signal seems to be going through, as when i record it shows the waves...you know the little jaggedy things that let you know you're recording, but playback reveals nothing to be heard. Likewise, i hear nothing plugging into the headphones or main out jacks. Can someone give me detailed instructions for an idiot? I don't know if this is relevant but i'm working on last year's model of Macbook Pro with a 2.4 intel, 2 gigs of memory, running 10.5.6, and i'm using Logic Pro. My attempt was plugging my guitar straight into the first input XLR/quarter inch with logic pro running. Granted, i don't really know what i'm supposed to do, so i could just be doing everything wrong. Thanks alot!
