By using the USB interface with the ASIO drivers, you do add a noticeable degree of latency for live play, which is why the analog/line-outs, with "Tone Direct" are preferable for live play/monitoring situations. I use the ASIO drivers strictly.
I have been using a UX-2 as my PC input device for years without noticeable latency. The GX can work just as well using the line-out. There are two ways to make this work for you:
1. Take the analog outputs/line out and feed them to the aux in of your PC's sound card (which is what I do)
2. Attach the analog outputs/line out directly to a powered speaker system (this is usually what Line 6 recommends, but I disagree)
Note that with the first option, you want to keep your PC's sound card as the default output device, and make sure that the aux input is enabled.Go to the full post
