Hi guys. I bought a Line 6 UX2 device a few days ago and I've been having a very annoying problem. Basically, I can't listen and record at the same time because I only record noise. For example. I recorded a simple riff without any problems. No latency, no noise, nothing. It sounds beautiful. I click 'stop' when I finish and as soon as I click 'record' again to record the harmonized riff the track gets filled with noise INSTANTLY. I don't even have to touch the guitar for this to happen. I can put it away, roll the volume knob all the way down and still if I hit the 'record' button the track turns into a very loud and very high pitched noise. The same thing happens when I import a song to my recording program. In this case the song is in the first layer/track and as soon as I hit the 'record' button when I want to cover the song, the track gets filled with noise instantly. I attached a picture that visualizes it. The track at the top is the first layer. The track at the bottom was meant to be a harmonized guitar, but I didn't even touch the guitar, and the track started filling with lots of noise. Has anyone every come across such an issue? If so, how do I sort this out? Thanks.
