Had rehearsal tonight with the DL mixer. Updated firmware just fine. No issues noticed. (Wasn't having any problems before either.) I did seem to get back a former saved show which included a singing member who is no longer with the band. Go figure. I'm trying to understand where it was hiding. (Does the mixer itself save any shows?) It's not a problem, but it was unexpected. Think this show was still on the ipad when it was upgraded previously. Since then I had experimented with restoring My Fader to the ipad. (Wanting to make sure it could be done before I needed it.)
