Answer a few questions
Where the reading isn't sure (a smudged lyric, a bar that doesn't add up), it shows you that spot of the page and asks.
Fix the rest beside the scan
A score editor with MuseScore's keys. The page you scanned follows your cursor, so checking a bar is a glance.
Take it with you
MusicXML for MuseScore, Sibelius, Dorico or Finale; MIDI for rehearsal tracks; a PDF to print.
What it's good at
Made for choirs
Lyrics under every part, verses, dynamics, hairpins, chord symbols, divisi and voices, and a piano reduction underneath.
Checks itself against the page
Lyrics are spelled from the page's own text. Low notes are checked against the ledger lines in the scan. Bars that don't add up are flagged, not guessed.
Lines of music like your page
The score breaks where your original does, so each line sits level with the scan you're checking it against.
Write music too
Start a new score from a template, play notes in from a MIDI keyboard, add text, repeats, endings and ornaments, and print.
How well it reads
Measured on real choir pages it never trained on. No reader is perfect, which is why the questions and the editor are there.
Lyric syllables wrong, 5-page piano-vocal score
0.4%ours
11.4% PhotoScore 2020
25.8% Flat
Lower is better. Against the corrected score (corrected by hand, starting from our reading, so it may favor us slightly). Ours before any proofreading.
Notes right, same score (pitch, F1)
97.0%ours
97.3% Flat
70.4% PhotoScore 2020
Higher is better. Voice, right hand and left hand averaged; every reader's notes lined up with the corrected score the same way.
Notes read wrong, 10 choir pages
7.5%ours
42.5% homr 0.7
48.9% Audiveris 5.11
Lower is better. Symbol error rate against hand-made answer keys for 10 choir pages none of them trained on; every reader's MusicXML scored the same way.
Lyric syllables wrong, same 10 pages
13.8%ours
36.4% Audiveris 5.11
Lower is better. homr and oemer don't read lyrics at all.
