AJ,
I should just email you direct .... we're the only two that seem to respond on these PA80 issues anyway! (kidding)
If I ever had a situation that required a second keyboard, I think it would be a tough choice for me. My left hand is tied to the bass, so there is not much time or room to modify settings. I guess I'd still like the have a dedicated piano or organ on the bottom of the rig.
