Ahhhhh . . . at least I don't have to feel stupid now for possibly having overlooked this feature on the beloved KN5000 which I thought I knew so well both 'inside & out'.

Alec , thanks for your explanation of the 'sound controler'. Sounds like a cool feature. The feature that's always intrigued me, though unfortunately I never had the opportunity to try it cuz I've never owned an arranger that had it is the dynamic arranger. Oh well. . . .
