Problems with G4P and Minim

Hi, I have some problems, I have this code, the idea is that the mic of my mac sense the note and compare this note with the midi note in the program, I think that I have some problems with detect correctly of the microphone, I don´t know if I need some code more like something to calibrate.
Also the idea is that when the note sensing with the microphone is not the same with the midi note appears an image like match to indicate that the note sensing is not the same that the midi note, the problem is that the image always appears.
Does anyone know how can I do?
thanks :D
