I'm not getting noticeable latency but when I take a previously built preset like an Austin Buddy Live Gold preset and switch to Dyna Cabs, I get barely controllable feedback. Sometimes when I switch back to the legacy cabs, the feedback stays. I power cycled the unit and it went away. Then when I switched to Dyna Cabs, it was back and was to the point where it was feeding back over my playing. Not sure if it's something I'm doing wrong or what. Austin Buddy's high and low cuts transfer over to the Dyna Cabs when I switch, too.
