I compose by keyboard and midi, and sometimes make parts for bass and guitar players. It would be great if the fret board input could show the notes that are being played when a score is played back, the same way that the keyboard input does. As of now, when I play a score, the white keyboard keys turn grey during the moments they are used in the score. It would be great if the same could be done for the fret board, which would allow me to make sure I'm writing parts that are natural to play.
