It is funny to see people criticize alternative MIDI keyboards. At least they are meant to be easier to play.
I can prove that the piano keyboard was a bad idea, its easy. See this?
It’s a finger stretcher for pianists. I don’t think there’s a similar torture device for other instruments.
Supposedly Robert Schumann ended his playing career with one of these by injuring his right hand.
Face it, the traditional piano keyboard is a BAD DESIGN. Its great that some companies are taking a chance and offering a better design.
