I THINK I HAVE MADE A MAJOR ERROR! Everything I have written is for the left hand, as applied to an arranger keyboard. Not in piano mode, or two finger chords.

My thought is to control everything with the left hand, right hand follows. The left hand is part of the orchestra (Accomp.)
The right hand adds the colors that you feel.

PS, I am going to record some of what I posted -- soon.
