Hey all.    Definitely on a budget here. I live buttcheek to buttcheek in a set of flats with no sound insulation (Neighbours either side, above and below). I am finding myself not wanting to practice because I am afraid of a knock on the door. What is the best way of practising with a backing track, no latency, through headphones with no sound/Mono/Stereo issues? Back 20 years ago, there were always problems trying to run such a setup.    Cheers!   R Edit
