It would be neat if they were to finally integrate Steven Kay's "Karma." Or at least SOMETHING, with some degree of randomness.

I'm not talking about playing random wrong notes. Just some paramaters to humanize the arranger's performance. As far as I know, none of the brands have ever attempted this. If it sounded a little different every time, or "evolved" in some random way, I might be tempted to keep practicing, just to see what happened next. And obviously a way to turn it off, for studio musicians or live performers.

When the instrument inspires you to keep playing, you know that you have something very special!
