Capella-scan is a professional note recognition tool to help you digitize your printed music scores. You can either use your scanner or open an already existing image file (TIFF, BMP, PDF, and others), and the program will accurately recognize all the elements that conform the score, including multiple voices, accidentals, cue notes, grace notes, ties, slurs, and many more.
This program owes its outstanding recognition capabilities to Tesseract 4 OCR engine, which Capella-scan uses not only for note recognition, but also to detect even the smallest and more complex features you can find in sheet music, such as brackets, curly braces, dynamics, keys, crescendo and articulation signs, etc. Complex scores with multiple voices, lyrics, etc., are easily digitized with Capella-scan. With its more than 100 different dictionaries, it is capable of recognizing and double-checking almost any kind of text. Capella-scan also includes a convenient MIDI functionality that will allow you to listen to any fragment or to a full score. You can configure Windows MIDI mapper to play your score using any of the 127 different instruments and sound effects available.
One of the beauties of this tool is the possibility of having both the original score and the OCR results in the same window, displaying one on top of the other. This useful feature highly simplifies the editing process, minimizing the time you usually spend correcting notation mistakes. Additionally, it may work as a conventional music editing program, allowing you to insert any note or sign that was left out during the scanning process or that was missing from the original score. For further editing, printing, and enhancing tasks, the program can save your scores into Capella, CapXML, MIDI, or MusicXML files that you can then use with other professional tools like Finale, Sibelius, or Encore.
v8.0.25 [Apr 29, 2013]
1. Note recognition
Recognition of most note objects was revised and now is much more reliable. Such note objects are eighth rests (and shorter rests), half note heads, cross note heads, treble and bass clef, symbol C, beams (especially thin ones), ties and slurs.
- Staves with strongly differing line distances which occasionally appear in PDF files are now accepted more tolerantly.
- Percussion staves with only one note line will be automatically recognized if they appear together with „normal“ lines in a system.
- Pedal brackets in piano notation are now recognized.
- Breath marks are recognized.
- Text and music symbols (dynamics etc.) from PDF files are taken over directly (when existing). Notes themselves are still recognized by looking at the created image (bitmap). This will only work for PDF files which were created directly via the print menu of a notation program. You can identify such PDF files by being able to mark and copy single symbols with mouse or computer keyboard.
- Greyscale information will now be applied for lyrics recognition, too.
2. Automatic image optimization
The scanned/loaded note image can be automatically optimized for note recognition before starting the recognition process. These optimization steps will be considered:
- Invert if white on black
- Remove shadows (greyscale images)
- Optimize brightness (greyscale images)
- Optimize contrast (greyscale images)
- Adjust page orientation
- Reduce too high resolution
- Remove white spots
3. Import/Export
- Improved Midi export (via capella-tune) with several export options
- Revised file dialogs:
- The capella file format can now be selected more easily in the „Save notation“ dialog.
- In the „Open image“ dialog there are additional PDF import options.
- In the „Save level of recognition“ dialog the image file can be saved as well.
- A converter PDF-bitmap is included, Ghostscript is still supported.
- Processing of colored images (scan, load, save)
4. Functions
- keys are now framed with a dotted red line to distinguish them from single accidentals.
- Improved means of voice reduction in the System Template as well as directly in the stave properties. Voices can be left out in order to create a voice extraction. This saves you from correcting mistakes in voices you do not need.
- Triplet note values can be interpreted either as reduced or as prolonged.
- Quarter and half note heads can be optionally accepted without stem.
- Graphic objects can now be anchored to barlines.
- In „Options“ you can set which graphic objects are to be anchored to which objects (to notes, rests and barlines) and if they are to be counted to the upper or lower stave.
- With the “Search” function text with differing font can be found and then unified. This way you will obtain plain text in capella rather than freeform text.
- Several settings are saved separately together with each level of recognition (playback tempo, voice reduction).
5. Objects
- Octave brackets
- Pedal brackets
- Free lines
- Quarter tone accidentals
- System brackets consisting of a straight line
- Program handling
- Object groups can be marked by multiple mouse clicks. Repeated clicking on a note head marks the head first, then its stem, then the beam or triplet group, then the accidentals, then the entire voice in the bar, then the entire voice in the stave, then all objects in the stave. Instead of quick multiple clicks you can also keep the Alt key pressed and then do multiple unhurried clicks.
- Duplicate objects with Ctrl drag.
- Zoom by pressing and turning the mouse wheel.
- System Template: Transposition, instrument, volume and voice reduction can be set with keys /- and 0...9.
