Big +1 here. We keep firmware/software updates carefully managed, but I’ve been bitten by this one on at least a couple of occasions early on with this desk.
I feel like One Mix is arguably the weakest part of the dLive ecosystem, for the compatibility-between-firmwares reason, but also because OneMix occasionally blows out all the settings for no reason whatsoever. …also also, two login screens for an end user? …and pan sliders that are really difficult to see when you’re actually touching them? No me gusta.
…we’ve jumped ship for the new “Control,” app at our primary venue. I have the user logins to burn, and all the layouts get stored on the desk. Customization isn’t as quick or dynamic as it is with OneMix (IE can’t drag and drop faders,) but so far it’s been arguably more stable, and the end user simply needs to open the app.
