Can the lyrics move forward automatically while we sing?
Yes. In Ormilio, set the seconds per line and press Play. The words move forward on every screen by themselves, and you can take over at any time.
Sometimes the leader is also singing or playing and has no free hand. Ormilio's auto-advance lets the words move on their own.
Set the pace
Choose how many seconds each line stays on screen, then press Play. The highlighted line moves forward on the big screen and on every phone together.
Live when you need it
Pause at any time, or switch back to live control and tap Next yourself. It is the same words either way, and every screen follows.
