SUS4 Score: Sheet Music Scan
Read, play back and export
Free · In-App Purchases
Choir on Thursday and your part is only on paper. Scan it, show just your staff, slow the playback down and learn it on the way in.
Read sheet music. Scan paper scores. Play them back.
Optical music recognition turns a photo of printed sheet music into notes you can hear.
Import PDFs or MusicXML, export MusicXML or PDF, and keep every score on your device.
SUS4 Score is a full-staff score reader with on-device heuristic music recognition built in. Import a MusicXML file, scan a paper score with your camera, and the app renders it cleanly on screen with correct notation. Tap play and the score plays back at any tempo. Navigate by rehearsal mark, zoom by pinch, and extract individual parts when you only need the violin line or the bass clef.
The MIDI roll view sits alongside the standard notation view so you can see rhythmic relationships clearly. MusicXML export means you are never locked in — take your score to Sibelius, Dorico, Finale, or anything else that speaks the standard format.
• Full-staff score rendering — treble, bass, and grand staff
• On-device heuristic music recognition — scan paper sheet music with your camera (results vary with print quality)
• Score playback at any tempo
• Parts extraction — isolate any instrument or voice
• MIDI roll view alongside standard notation
• MusicXML export for compatibility with any notation software
• Subscribe monthly, or unlock forever with a one-time purchase: unlimited score imports, parts extraction, MusicXML export, and MIDI roll
Runs on-device. No audio or score data sent to a server.
