Hi Don,
maybe you could try it with your Roland, using it as a soundmodule to see how it works and then maybe consider some sort of a soundmodule.
The korg loads samples, but I don't know if there's anything commercially available specifically for the pa3x.
I played around with loading wav files to put together a bit of a live drumkit for a couple of my ketron conversion, but I found time consuming, and discovered it was a bit beyond me. haahaa. Decided I'll probably go back to using the sd2 should I need the Live drum sounds.
Rikki,
Thanks for the information regarding using PA3X as controller. It's something I may try at some point.
All I really would like is a few electric guitars though. I need to do some looking around and/or editing.
