I'm having trouble getting any sound at all or even having any Input with Pod Farm plug in using logic express 8. I dont know if its something with line 6 drivers and mac compatibility. It works perfectly fine in stand alone. I do most of my recording using a presonus firebox and thats the default sound device. I have to unplug that to use my GX and it doesnt read as any sound device, so i have to use the computer speakers built into the mac and it gives me little guitar and a lot of horrible noises and feeback. Never had any problems with ANY plug in besides THIS one.
