Zuki... there's a lot to be said for footswitch pedals if you don't want to look down a whole lot. One reason I think the BK-9 is so good. A seven switch pedal in a MOTL arranger.

Nice!

Anything you can do with your feet is something you don't have to take your hands off the keyboard and look for while you press buttons...
