Cliff,
Playing your example of E087 helped alot. What I could see was that the B module of Karma was assigned to the upper part of the keyboard and A,C and D modules were on the left and are triggering "patterns" so the overall effect is exactly like a arranger on the left and a melody on the right. Now, if I could understand the technology (need a Korg Rep to come to the store) maybe I could see how hard this would be to make some of these up with different style types. I wonder if you can find Bossa Novas, etc.......probably not. I'm thinking to much like my arranger kind of guy I am. I'm driving the guys in my store crazy right now......they want to know why I would even want to make Karma into an arranger...........they think I have too many arranger now!..............Never too many arrangers for me!
