As I talked about scanning in my Technology in Music Education workshop yesterday, I noticed that SmartScore's NoteReader had been released on the App Store on the 15th. The app itself is free, but if you want to export any of the data, you have to pay $9.99 for the premium upgrade.
SmartScore NoteReader is an app that allows you to scan and then play music (for free), and then (as an In-App Purchase) to export data a number of ways (including e-mail and Dropbox) so that you could import that data into SmartScore Pro X2 or any number of music notation programs, such as Finale, Sibelius, MuseScore, and Notion.
SmartScore NoteReader allows you to take a picture(s) of a score, import a picture of a score, or import a PDF to recognize. In comparison, NotateMe's PhotoScore In-App Purchase allows you to take a picture (or a series of pictures) of a score, but importing a picture (on iOS) requires working through other apps, such as Mail. At the moment, NotateMe does not allow you to import a PDF. As a result, in terms of working with existing documents, NoteReader is easier to use than NotateMe/PhotoScore.
I have only done a few scans with SmartScore's NoteReader so far, and initial trials indicate that NotateMe/PhotoScore is more accurate than NoteReader. On a one part score, SmartScore's NoteReader scans with equivalent accuracy to NotateMe/PhotoScore–when all staves scan. NoteReader dropped staves that NotateMe/PhotoScore did not. PhotoScore also does a better job of handling lyrics–more lyrics are accuate than on NoteReader, although there are errors with lyrics on both apps.
On a single line band score, I would estimate that NoteReader is scanning at 75% accuracy while NotateMe/PhotoScore is scanning at 95% (or greater) accuracy. In a multi-page choral score, NotateMe/PhotoScore stays at 95%, while NoteReader's accuracy diminishes greatly (50% or less).
I am using the same set-up for scanning for both apps, with an iPad “document camera” stand and an iPad 4. It is possible that a closer photo could yield a more accurate “reading” from NoteReader; but I have noticed that NotateMe/PhotoScore tends to be a little more accurate when you don't zoom in very close to the page! Additionally, I would assume that the better the camera (in other words, with a newer device or an iPhone), the better the resulting accuracy of the scan. So, if you scanned with an iPhone 5S, you might have higher accuracy with both programs.
Again, these are preliminary tests, and both apps are in their first weeks (or days) in the App Store. Undoubtedly, there will be app updates in the weeks, months, and years to come. It is exciting that you can scan music on your iPad (or iPhone, or Android) device without the need to purchase a scanner.
In terms of accuracy, NotateMe ($39.99) plus the PhotoScore In-App Purchase ($29.99) is currently the winner, by a large margin (particulary when dealing with multiple parts). In addition to scanning, NotateMe also is a handwriting-based music notation app which allows you to edit those scans after they have been recognized by the software. NotateMe's ability to “Open In” feature is useful when exporting the data to another app (such as Notion). Both apps allow for the use of Dropbox.
In terms of built-in useability (selecting existing images, using PDFs) and price, SmartScore's NoteReader (free, $9.99 In-App Purchase to export data) is ahead of its competitor. At 1/7 the price of the NotateMe/PhotoScore package ($69.98), NoteReader might be worth purchasing. And remember…both SmartScore and PhotoScore are very expensive desktop programs, each costing nearly three times the price if you were to buy both of these apps!
And if you want to just TRY these apps, NotateMe does have a “lite” version called NotateMe Now (allowing for one score at a time) which DOES include PhotoScore, and SmartScore's NoteReader is a free app (until you want to export data). So…if you have an iPad, iPhone, or Android device (note: the camera on the iPad 2 and the original iPad Mini are not high resolution enough to work with some apps, such as NotateMe), at the very least download the free versions and see what these apps can do!
Note: In the image above, I show what happens when you export the MusicXML file generated by these apps into another app (in this case, I printed these to my printer from Notion for iPad). Compared to the original score, both apps could not determine an existing multi-measure rest (there were 3 in the original file). NoteReader dropped the first and last staves of the original; NotateMe/PhotoScore's greatest issue was the addition of a second note to a number of notes in the score. Both scores picked up key signatures, clefs, and time signatures changes (meter changes) in the original score, and both can play back what they have processed from paper to digital notation. Just remember…whenever you scan in music, there will be clean-up. The important question at that point is: 'How much clean-up do I have to do here?”
