I found that I can load the background track on my computer with audacity and play along with that and also record at the same time. I tried the aux out to computer mic input but the computer did not like the impedance and only got a crackling noise. The only problem with using the computer and recording with audacity is that I can't do it with headphones and disturbing other people in the house. (The noise, not that I play that bad.) So still no luck with recording along with the amps drum loops.
