SharpEye Music Reader converts a scanned image of printed music into a MIDI or NIFF file. It does not support direct scanning but will accept BMP and TIFF files.
Used at its simplest, you drag an image file into a window, click on a button and wait for the conversion to take place. The output is shown in conventional music notation in another window. Click on another button to save the result as a MIDI or NIFF file.
Usually there will be some errors in the output: SharpEye has a built in editor for correcting them. Almost all the editing can be done with the mouse and delete key. The input image window automatically scrolls to the right place in the image as you edit. SharpEye also shows warnings for each bar which doesn't make musical sense. This acts a bit like a spellchecker and directs your attention to likely errors.
