Diki, you mentioned somewhere that you love the super natural guitar sounds in the BK-9. Today I understood what you meant, I didn't know that supernatural means that you play like you would play a regular piano piece, while the sound engine would take your playing, process it, and put out a guitar sounding piece. I almost fell off my seat when I heard it how it sounds, especially that Nylon Guitar, it's unbelievable what this keyboard does.

Although I don't hear much in the Grand Piano, I don't know what to look for any suggestion?, but the guitar definitely stands out.
