Hi John
It would be helpful to know which IPad you have and the type of connector at the bottom. Also how you are connecting the IPAD & Key Board together.
One thing to try though, tap the COG Icon in the Songbook app, then tap MIDI.
On the next screen at the very bottom you will see”Control Mode” in this select your keyboard.
See details on pages 10 & 11 in the manual.
Another question - when you open the Songbook App and look at the list of songs, are they showing up as UNUSED SONGS, if so select Edit on the RH Side. Then click on the green Plus sign, make any changes to title etc then Save.
If they are showing unused, you will not see the three little dots to the left of the MIDI symbol.
Regards
Bill
