I got my Steinberg UR22 audio interface today. I wanted to see if I could get lower latency. With Rig Kontrol 3 I was getting about 11.5 ms total latency at 48000 and 32 samples. With the UR22 I get about 5.8 at 48000 with 32 samples. My Steinberg MR816x which is a rack unit with firewire gets about 3.2 ms. The UR22 may be slower because it is USB 2.0. Anyhow, it is a small 2 channels in and 2 out. I take the two out and run them to the right an left channels of my Fishman SA220. It sounds about the same as the Rig Kontrol 3, and probably a bit better. Hard to AB them without lots of lag time. I will try an AB by recording both to my Boomerang looper and see if I can tell a difference. Seems like a good unit for $149.
