The "mis information" certainly was not helped by the old QVC and HSN spots where a guy came out with a keyboard that played itself... always at Xmas - the keys lit up and you just chased the keys that lit up and voila - you were an instant Liberace... ha ha. Tempo didn't matter either as long as you could follow the lighted keys. Sadly, with those products and video games like "Air Guitar", folks tend to not really think or care about what "might" be required to make the music sound good.
