They've been using these types of controllers on electronica for years (AirFX, for instance, not to mention the theramin
). Nobody worries about that. Main thing is the connection between visual gestures and something you can actually hear.
I'm a fan of what Bjørk's electronica guys do...
The general public doesn't believe we are playing the keyboards if we go out front and put on our chicken hats and have the sequencer play the song
If we stay behind the keys and play with one hand and use the other for the D-Beam, no problem! At least they can see us doing SOMETHING...
