Beat unit

Leave the default: it follows Puji Syukur practice, where a quarter note is the plain digit even in 2/2, 6/8, or 7/8. Switch only if the source expects the formal denominator rule.

Built for choirs

The three things that matter most — everything else stays out of the way until you need it.

Digital sources

MusicXML is read directly. Born-digital PDFs — MuseScore, Sibelius, and Finale exports — are read from their embedded music glyphs. No image guessing, no optical recognition errors.

Beat audit

Each voice in each measure is counted against its time signature. Overflowing measures are marked !, underfilled ones ? — printed right in the PDF.

Puji Syukur

Key signature, meter, reference octave, and church modes follow Puji Syukur practice — ready to hand out at rehearsal.

Under the hood
03 / 03

Measured, not promised

What the research behind the converter actually established.

Glyphs over OCR

On real-world choir PDFs, reading embedded glyphs passes far more files than optical recognition — seconds per file instead of minutes of correction.

Two readers

Every print run is cross-checked by two independent readers; the measured agreement rate is published with the method, warts and all.

Octave rule

The plain octave of scale-degree 1 is derived from each part's actual melodic range and validated against seventeen Puji Syukur Kor pages — not from the tonic letter.

Scanned or photographed?

Scans carry no music font, so they cannot be read accurately — such files are rejected with an explanation instead of being guessed at. Re-export to MusicXML or PDF from your notation app whenever possible.
