Second update- played a show using the 'Hawk ( v 1.01) with an outboard expression pedal (EX-1). Had three episodes of sudden loss of output in three hours- one at sound check, two during show. I was very heavy on the good ol' "tap-dance"- frequently changing effects, patches (sometimes three per song), lots of volume swells and parameter control using both pedal controls. I must say that the latency/ delay in patch changes was decent.
Never had the A/D lights of death. The only display quirk is isolated loss of the master volume LED's or loss of all LED's. All patches involved were downloaded or built from scratch. Fortunately, I never lost output in the middle of a solo. In every instance, I quickly re-booted , then navigated back to the user banks and got back to business . I learned that the master volume ( big knob, red lights) reset to a lower level each reboot ( which is better than screaming loud!).
Despite these sudden failures, I'm getting good sound and good control. I concede I wouldn't want to lose output in the middle of a solo or in a three-piece band. I'm a die-hard Line 6 user and will probably continue to use the 'Hawk.
Judging from the feedback (har har) , it seems that there is more than one specific corruption (error, bug, code issue) .
Line 6 , what say ye?
Cheers
