Trevor....I'm confused about why you use a "midi controller board" to play the left hand. What's wrong about playing the Korg directly (with the left hand)?

and...

if I find a style too "busy" what are my options towards "quieting" it down while I'm playing?

I don't read when I'm performing....I do everything out of my head. Hence, access of controls and "speed" is important to me as I tend to go from one song to another.
