I hear you, Donny. I think these kinds of videos have their purpose for some, and may even be entertaining (except the Polish ones!).;)
I hope videos showing technique, editing sounds, etc. like you said start to appear.
Technology is growing exponentially, so who knows what they'll come up with in a few years!
They way it's going as you can also see in the polish demo......
sadly the arranger KB as it was once known is becoming a karaoke, play-along with machine for professional use,...or it will sink back into the "HOME" players living room Hobby instrument as the automatic organ was.
