OK, I dropped the "or" and replaced it's output with a "1".? Still not switching.? Something funky going on here.? I'm using a ipad recently set up as a touch screen.? I know it's communicating with the processor because in my little test program I have a Dune media player set up for IP control and have normal communication /operation with the Dune.? One thing I miss from upgrading from a Pro2 as all those LED's on the front panel.? Super easy to see if you're communicating.? Just look at the front panel
