I tried a new setup and now my recordings sounds bad. I got a audio interface (fast track) and a couple of krk rokit5 and plugged the audio interface into my usb plug. I'm recording using audacity. I can play the backing track and play my guitar without recording and it sounds fine but soon as I hit the record button the backing track get muzzled very bad. are my settings ok, i put fast track as my input and out device. I've used audacity without any problems the old way which I plugged my gt-10 into my sound card and never had any issues, but now gt-10 going into my audio interface and my monitors hooked up it all messed up. any idea's
