I downloaded the pod farm software off of the website for free and im trying to use it with my usb guitar but i cant figure out how to make it work or if it even will work. Im trying to plug my guitar straight into my computer with the usb port (which only contains an audio signal, NO MIDI). I AM NOT trying to use a UX type guitar port where there is something between the guitar and the computer. Is it at all possible to use this program by ust pluging my guitar into my computer using the usb cord i have?
