to work with Sonar - November 02, 12 5:21 PM ( #3 ) I use Line 6's UX1 and have never had any issues, even before I upgraded my previously terrible PC. It must have something to do with what latency settings you have. Also, check the Asio panel on hs7 and make sure you have latency set to extra small. It will use up more of ur CPU, but not too much.
