After a pretty careful look at the Prelude’s manuals, I don’t see the slightest evidence or hint that you could ever externally select a Performance…

One interesting find… it seems the Prelude is the only pro/semipro arranger to have the ‘Catch + Last’ mode for the bend lever…. Play a note and bend it, but subsequent notes played are unbent until you move the lever back. This would allow you to do a double stop bend like guitarists and string players can. Let me know if this works for you!
