Hi all, I have a line6 toneport ux2 connected to my computer. I've been plugging a microphone into it and then recording some drums with audacity. It used to be that I could record a track with audacity, and then after I was done, hit record again and it would play back the first track while recording the second one. I like to fool around with building up little percussion jams with myself this way. Well, today I turn it on to fool around and it will record just fine, but for some reason it no longer plays back the other tracks while recording the new one. Any ideas as to what setting I've screwed up? It used to work just fine and I haven't changed anything about my computer that I know of. Thanks for any help.
