I am a new SQ User and have recently used the SQ for few events. Few things I observed.
I tried to use the Offline mode on my Mac-Air to setup the IO Routing, but the screen only shows me upto MainLR and I could not get to Matrix outputs. To assign Matrix, I had to push the show to my SQ and then use the Screen on the SQ to set the Matrix routing.
Have a Scroll-bar or a Zoom +/- option on the screen will help get to all the outputs.
Did click and drag and/or zoom (using two fingers by default on a mac) not work?
If not, please let us know using support.allen-heath.com with details on the model and OS so we can log this.
