I installed the ADJ 12PX Hex unit in the editor and it responds well in the "Steps" editor. When I go to pushing buttons in "LIVE", it flickers and blinks intermittently. It also occasionally 'blacks out' for half a second when I switch from one "solo" button to another. I also have the "flash" button giving me the same problem.
In some ways, it seems like a cable issue. But it works fine in the "steps" mode.
