Display and text size

Everyone reads differently. Under Display you set up the sheet the way you want it. It only applies to you, the rest of the band sees none of it.

How to do it

Open a song
Tap Display at the bottom, the button with Aa
Under Text size, make the text bigger or smaller
Under I sing, choose No, Lead or Backing
With Backing, your lines light up.
Tap next to the panel to close it

Light screen: white with black letters, for bright light or outdoors.
Capo for this song: for guitar. Turn on the switch and choose the fret. It only applies to your sheet, and only to this song.
View as another instrument: have a look as the bass player or drummer, for example.
Notation: if the band has its own way of writing chords, you choose here between Above the lyrics and the band's own.
The song as: for drums on a phone. Choose Blocks or Lyrics.
Auto-scroll: see Auto-scroll and the metronome.

Go to Settings and, under How I want to see songs, choose your own instrument. Then every song opens that way. See Settings.

Yes. The text size applies to all your sheets. You can also set it under Settings.

With drums in blocks there is no text on screen. The text size then does nothing.
