Is anyone experiencing interface disconnected during a set? All 3 nights that I have used my 57 at least 2 times per night for no apparent reason the music cuts out and the screen says interface disconnected as if the mixer is unplugged. Then the music cuts back in after several long seconds. Any advice is appreciated. Peace.

Used to happen on the SL-1. I know it sounds silly, but change the cable. Cables dont go bad per se, but the connectors do get a lot of wear and tear. So give that a shot.

Thanks, I'll try it.
