Hi Stephen,
I got just the WIFI model, with the keyboard dock and a case.
The only worry I have is there is no USB port. Which is what I use with a footswitch page-turner.
The Line 6 MIDI Mobiliser does allow MIDI in and out, but only through its own app...
I find it too difficult to jump from the keybed to touch the screen to turn a page.Usually my hands are too busy.
Anyway I will see how it goes. I can return in 14 days if it doesn't work out.
Dennis
