John, You do have a real sense of humor
The automatic song/keyboard control is working like a charm! Took it out for its first gig last week. I had a set list configured on my Pa4x and as soon as I picked tune from the Pa4x set list the corresponding lead sheet was on the Pro12 immediately. Talk about keeping downtime between songs to a minimum this set up does the trick. I'm posting some photos that I took while deciding the best way to set up my new tablet holder with the wiring, it's not very neat but was all part of deciding how I wanted the set up.
I set things up so that my mic boom and tablet holder both connect to the x-stand no need for any additional stands.
The only additional cable I need is a USB cable that connects from the 4x to the Pro12 tablet.
