Cubase SE (full cheaper version, which is down to $99. on Musicians Friend, and probably American Musical Supply)Cakewalk Guitar Tracks Pro. Also, a Line6 Guitar Port, which I plug my guitar into the Port, plug the Port into the computer by way of an USB cable. I can jam and/or record with different amps and cabs and effects, interchangable; but with my computer's recording software. Plus I can use the Port to hook my guitar up, via "Line in", with other virtual music studios and software.
