Features at a glance

Scores and charts

• PDF score library — import, organise, read and annotate PDF sheet music.
• Chord charts — create and edit charts natively, with sections, repeats, time-signature changes and navigation signs (D.S., al Coda, double bars, final bar).
• Blank pages, canvas and manuscript paper — create empty A4 pages, free-drawing canvases and blank stave paper inside the app.
• Scan & photo import — scan paper sheet music with the camera or import photos; they become PDF scores.
• Chart import — bring in .html, MusicXML and MIDI files as editable chord charts; import .4ss setlists.

Keys and transposition

• Transposition & key control — transpose with one tap, keep an “Original key” reference, lock keys, and hold different keys for the same song in different setlists.

• Text Mode — type text blocks directly onto pages, with adjustable font size.

Setlists and live use
