I need to develop a performance evaluator for playing the piano. Based on the midi created from the notes, I need to evaluate the midi of the actual playback (midi keyboard). I plan to evaluate the game based on the key of the note, duration and volume. Evaluation is perhaps a comparison of notes of a note and a game of midi.
But I have no idea how I can visualize (that is, show where a person did wrong), this assessment process. that is, it may appear as a designation or highlight what note went wrong. But how can I show this in some kind of graphic form? Or, more precisely, on the foot (musical score). I have record information (step, duration) and evaluation details (key and temporary signature) stored in a table, and I use Java. But I have no idea how in how I can put all this in a graphic form.
Any understanding is greatly appreciated. Thank you for
