battuta: Score Editor

battuta is a music notation editor that works the way a text editor does: a caret that walks through the notes, a selection, copy and paste, and undo that always lands. Your score is an MEI file, the open format of the Music Encoding Initiative, and it stays yours. • Write music by touch with the on-screen keyboard, from a hardware keyboard, or by playing a MIDI instrument connected by USB or Bluetooth. Accidentals follow the key signature, and what you enter always adds up to a full measure. • Arrange in blocks: select measures and staves, copy them, paste them into another staff or another score, transpose them. • Ties, slurs, articulations, ornaments, dynamics, hairpins, pedal and fingering; tuplets and grace notes; lyrics, chord symbols and Roman numerals. • Repeats, voltas, segno and coda, and playback that takes the jumps you wrote, on the built-in piano or on your own MIDI instrument or app. • Transcribe with a PDF of the original beside the score, or with a recording's pitch traced over it. • Open MusicXML, ABC, Humdrum and Plaine & Easie; export SVG pages, MIDI, Humdrum and Plaine & Easie. Page view shows the score engraved as printed pages. • Your scores live in battuta's own folder in the Files app, or in any folder you pick, iCloud Drive included; the share sheet sends a score or an export anywhere. battuta is made in the open by Vibetuned, a non-profit for music and arts education. It is free software (GNU AGPL v3): no account, no ads, no tracking, and it never connects to the internet — nothing you write leaves your device. The source is at github.com/vibetuned/battuta.
