Thanks for answering. I can do a few minor tweaks with the software. Kontakt will allow pitch bend setting changes (which lock to 1 whole step in local off mode. I think you told me what I already suspected, that the psr won't let me remap, and I need a dedicated controller.

But the 540 can still be useful for playing out ideas quickly to a floppy without having to wait for sampled voices to load.
