Update
I've been going back and forth with support and they've been great. Apparently, there's a known issue with delay/reverb trails being cut off when using main, monitor and direct outputs, of which I use all 3 for live gigs. I believe they are working on a fix but right now there's not much I can do.
I run my KPA like this live
main - FOH
monitor - alto 112
direct - dedicated IEM system that the band controls
Been doing it like this for over a year with little to no issues. Hopefully they get a fix soon.
