I have a new partner that uses Onsong. He is very resistant to change. Is there any way to scroll His lyrics over Bluetooth with my iPad running BandHelper? I would suggest a pedal for him but he performs sitting down on a stool.
If you're both viewing lyrics, you can use Live Sharing to share your paging or scrolling actions with his device:

Otherwise you can help him set up auto-scrolling:
