Hi everyone. I once posted on here about adding led fixtures to an etc express 120 board. Thanks for the help and all went well patching. But after patching and assigning channels, I can raise levels by accessing the channel and changing intensity, but when assigning to a submaster, the is no light and the channel levels do not appear to raise on the screen although the bunp button is lit as if it was assigned.Not sure what the problem is, it seems like i am missing something simple but not sure. Any ideas?
