I'm not even going to comment on the sound or even the guy doing the demo. I just can't understand why they would design this thing with the panel controls (including the arranger controls) so far away from the player.

Wersi's will always be designed for the "organ" player. You get all the drawbars you need right there at your fingertips.., but everything else (as it appears from Wersi's design team).., must be secondary to the organ player. Including reasonable access to the arranger controls.
