Interesting fix… First to answer your question. Yes, it simply stopped working, during a rehearsal, and the I/O setup was assigned correctly to socket 1. So per your recommendation, I assigned Aux 1 to a different socket and it worked at the new socket location, so I reassigned it back to socket 1 and Ta-Da it started working in its original socket 1 location. A bit concerning, but the lesson here is I have to start thinking in a software based environment, not a hardwired one. Tks, dB
