I think I might stupid or retarded for asking this question. But what's MIDI? my Casio WK-210 has this General MIDI logo on it and idk what that means. My piano teacher long ago told me it was cool and the information he game to me was apparently useless.

Yes, I did look it up on wiki. But the words intimidated me to finding a general and basic summary of information about here. I just had a "too long, did not read moment"

Thanks for answering. Kthxbai
