@ccp3 You, sir, either know nothing of music, or are a troll. Nobody cares to hear, or is better off in life because of your ill informed critiques. Before you post, think to yourself, "Self, if I were the creator of this device, would I want to hear what I am about to say?"
bad, dosent even have correct 50% of what my piano/synthesizer has.
if you are doing the guitar chords, maybe you could do a guitar neck with about 12 frets (because that is really all you need) and every fret on every string can light up individually. thus showing the notes of a chord. maybe an ARAY and PSTN cross reader could be the go. look at arK's reader save to see what i mean.
