I have a pianist friend. She is a littlesighted. She feels anxious because her eyesight weakens day by day. She loves playing the piano, but it's hard to read sheet music. I can read a book for her, but I can't read the score. If she could take a picture of the score and make it a MIDI message, she would be able to play the new score on the piano. For her, make connector that makes the score a MIDI message.
