Eighth rest or smudge
capella-scan can recognize pitch and pitch length, rests, accidentals, keys, key signature and time signature. It also recognizes brackets and curly braces, distances between staves, slurs, ties, repeat boxes, articulation signs, staff size, cue notes and much more. Note recognition is a very demanding process that requires software to accomplish something that in principle is only possible with human experience. When is an undefined mark on the music sheet a note, an eighth rest or simply a smudge?
Of course you know that text recognition programs do not always work completely error-free. This applies for note recognition programs as well.
Our experience shows that with many scores we achieve a 100 % recognition. With more complex ones, still more than 97 % are recognized.
However, there are scores such as handwritten ones which will produce unsatisfactory results.
If the software does diagnose an eighth rest for a smudge, you can edit it out using the same capella-scan program. It comes equipped with intelligent tools for this very purpose. The whole process is very fast and takes only a few minutes for medium-sized scores, sometimes only seconds!
Of course, you can always make changes later after exporting the file to capella (or Finale, Sibelius, Encore etc.).
All in all, you will find using this powerful note-recognition software extremely useful. Depending on how fast you work, typing out sheet music manually takes between 20 and 100 times longer than using capella-scan!
