An imported chart isn't a picture — every chord is a fact you can change. Editing is built for the two minutes between soundcheck and downbeat: tap the thing that's wrong, fix it, play.
Tap any chord on the sheet and type what it should be — G7, F♯m, Bb/D, whatever the song needs. Tap a word that's missing its chord to add one there. New chords speak the same language as everything else, so they transpose with the song from that moment on.
Charts miss things — a tag the band added, a turnaround only you play. Add a line anywhere: words, chords, or both. A note to yourself ("watch the stop") prints dimmed, in the label's typeface, so on a dark stage you'll never mistake an instruction for a lyric.
Tap the song's title on the sheet and type. The name in your library is the name you'd shout across a stage — make it the one the band uses.
Edit text opens the raw text behind the chart — exactly what the reader saw. Fix the stray chords, tap Chart it, and the sheet rebuilds. Your key is settled state: repairing a typo never re-guesses the key or moves your transpose. Fixing what you have beats re-shooting almost every time.
