I was wandering can I use my guitarportxt to plug into my computer and record to audacity? and if so how do i go about doing so? I asked in the audacity thread also but nobody answered yet and I have a song I really want to record.
yea its an audio interface except it only have a guitar input...

plug it in using the USB cable and in the perfs of Audacity, set the input to the line6 product.
you may have to install the line6 software in order to get the hardware working. I know the toneports wont work unless GearBox is installed as its normally the drivers with the software.
