Ok, so my friend let me borrow his lexicon omega because he doesnt use it. Im using a macbook and garageband. Im not exactly sure how to use it and the manual wasnt so helpfull. I have a 9v power supply plugged in on the back... im just recording my bass through it. I also have the usb plugged in. On the front there is an instrument plug in, so I plugged my bass into that. Fooled around with the audio settings and had to change my audio drivers in garageband for the input to Lexicon Omega USB and I put the output to Lexicon Omega USB as well since I plugged my headphones into the front as well. There was an option in the audio drivers for Lexicon Omega 1-2 only and 3-4 only as well, but I just put it on the Lexicon omega usb. Now in garageband everything seemed to be working ok, I could hear myself play back, set it for usb assign 1-2. But there is an AWFUL distorion. So I was messing with the knobs and found that the intrument input volume is controlled through the Line 3 knob, turned to maybe 2 and was the same distorted sound just super low... so im turning to talkbass for help... sorry if I confused you... maybe if someone has one of these they can just take me step by step on what to plug in and press etc to record just bass in garageband..
