It doesn't work, I've tried several methods. The samples are .tif files and bitmaps. It won't take anything else or it won't load. I converted all my jpegs into .tif bitmaps and it loaded but the recognition process destroyed it, Filled with missing and wrong notes. Maybe I'm using it wrong, who knows but I'm just a normal guy who needs a working midi file from a jpeg of sheet music. This promised it but didn't deliver.
