Guitar Rig comes with a controller pedal like this





but could I control guitar rig or similar programs with something like this?





if i ever did get to jam with some peeps i wouldn't mind jamming through my pc at all. i'm just wondering if i could buy some kind of foot controller to control the vst's on my pc?

if guitar rig is midi controllable then i dont see why not
