hi. I'm planning on setting up my own little recording studio at home. nothing too fancy. just webcam+a device like the line 6 toneport or pod studio. just enough to get a decent quality for a guitar track since I'm 2 lazy to go down to the studio every time they hold a rehearsal. do i live pretty far from the place so its kinda of a hassle as well.

now what i need to be doing is. be able to record a video of me+the guitar in the audio input. but what throws me off is how do i get a back tracking going. i seen many youtube videos where the guy doing a cover and the tone is distinctively coming from a midi port.

any help would be appreciated. thanks
